Small but significant is good. It’s especially helpful during short periods of extremely powerful physical activity, particularly if those short bursts of activity are repeated, as in weightlifting, sprinting or football, for example. The study also says that creatine supplementation is associated with enhanced strength gains in strength training programs, which could be related to the greater volume and intensity of training that you can achieve when you’re taking creatine supplements. Plus, according to the study, there’s no evidence of gastrointestinal, renal or muscle cramping complications – more good news.
Side-Effects: While the signs of a great body may make one think that there cannot be anything wrong with bodybuilding supplements, the facts speak otherwise. Bodybuilding supplements do have side-effects and you must listen to your trainer before giving in to the thoughts of buying one. Creatine can cause heart problems, kidney problems, dehydration, diarrhoea and muscle cramping. You must also discuss your medical history with the trainer. 
Other areas of research include therapeutic uses of creatine to help patients with muscle wasting caused by disease states such as muscular dystrophy and amyotrophic lateral sclerosis (ALS). Small-scale preliminary studies show some gains in strength may be possible for these patients, which could improve their quality of life. One study of 81 patients with various neurologic diseases found that giving 10 g/day of creatine for five days, followed by 5 grams for another week, increases their muscle strength by about 10% [20]. Large-scale studies should be done before recommendations are made to such patients.
Though weight training can stimulate the cardiovascular system, many exercise physiologists, based on their observation of maximal oxygen uptake, argue that aerobics training is a better cardiovascular stimulus. Central catheter monitoring during resistance training reveals increased cardiac output, suggesting that strength training shows potential for cardiovascular exercise. However, a 2007 meta-analysis found that, though aerobic training is an effective therapy for heart failure patients, combined aerobic and strength training is ineffective; "the favorable antiremodeling role of aerobic exercise was not confirmed when this mode of exercise was combined with strength training".[36]
Creatine supplementation often causes weight gain that can be mistaken for increase in muscle mass. Increasing intracellular creatine may cause an osmotic influx of water into the cell because creatine is an osmotically active substance [10]. It is possible that the weight gained is water retention and not increased muscle. The retention of water may be connected to reports of muscle cramps, dehydration, and heat intolerance when taking creatine supplements. It would be prudent to encourage proper hydration for creatine users. Further research is needed to investigate these and other possible side effects.
Without supplementation, approximately 14.6mmol (2g) of creatinine, creatine’s urinary metabolite, is lost on a daily basis in a standard 70kg male ages 20-39. The value is slightly lower in females and the elderly due to a presence of less muscle mass.[35] This amount is considered necessary to obtain in either food or supplemental form to avoid creatine deficiency. Requirements may be increased in people with higher than normal lean mass.[35][198] Creatine excretion rates on a daily basis are correlated with muscle mass, and the value of 2g a day is derived from the aforementioned male population with about 120g creatine storage capacity.[35] Specifically, the rate of daily creatine losses is about 1.6%[199]-1.7%,[25] and mean losses for women are approximately 80% that of men due to less average lean mass.[35] For weight-matched elderly men (70kg, 70-79 years of age) the rate of loss of 7.8mmol/day,[49] or about half (53%) that of younger men.
The last survivors of the pro-hormone supplements, which were removed from sale last January, estrogen-blocking supplements aren't pro-hormones but do inhibit the enzyme aromatase, which converts androgens into estrogens. In normal men that enzyme is ubiquitous, being present in such tissues as muscle, brain and skin. About 20 percent of the free testosterone circulating in the blood is converted into estrogen by way of aromatase.
In the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger, Franco Columbu, Lou Ferrigno, and others in the 1977 docudrama Pumping Iron. By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion,[7] who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
Do you know what happens when a person attempts to build muscle faster than they legitimately can? They fail, and then they wonder why it’s not working as quickly as they thought it would. From there, they’ll jump from workout to workout, diet to diet and useless supplement to useless supplement in the hopes of finally finding the missing link that will make it happen. But they’re never going to find it. They’ll just keep wasting their time, effort and money searching for something that doesn’t exist.
A double-blind study provided 20 g/day of creatine monohydrate for 5 days to qualified sprinters and jumpers who performed 45 seconds of continuous jumping and 60 seconds of continuous treadmill running. Supplementation enhanced performance in the jumping test by 7% for the first 15 seconds and 12% for the next 15 seconds, but there was no difference for the final 15 seconds. There was a 13% improvement in the time of intensive running to exhaustion [12].
When splitting a sample into exercisers and non-exercisers, it appears that exercise as a pre-requisite precedes a higher range of activity. Inactive people tend to be on the lower end of creatine kinase activity and relatively clustered in magnitude, while exercise generally increases activity, but also introduces a larger range of possible activity.[56]
Elsewhere, it has been noted that in chronic progressive external ophthalmoplegia (CPEO, a progressive weakening of the muscles around the eye and a mitochondrial disorder), there was a failure of creatine supplementation to benefit symptoms when subjects were provided 20g daily for four weeks.[483] Creatine supplementation failed again at 150mg/kg for six weeks in people with either CPEO or another disorder associated with single gene deletions affecting the eyes (Kearns–Sayre syndrome, KSS) in improving muscular function.[484]
Phosphocreatine is known to be a major source of energy for cardiac tissue alongside fatty acids, which are dominant under periods of normoxia (normal oxygen) while phosphocreatine becomes more important in periods of hypoxic stress.[281][282][283] The entire CK system plays a role in the recovery of the heart following ischemic/hypoxic stress, since blocking CK activity impairs recovery[284][285] and overexpressing CK activity promotes it.[286] This is due to the heart tissue needing high energy phosphate groups at this time, and the ischemic stress reduces CK activity and the ability of CK to donate these groups.[287][288]
Based on the limited data on performance and safety, some authors have not identified any conclusions and do not recommend its consumption in regards to creatine supplementation in children and adolescents [52,54]. Conversely, according to the view of the ISSN [5], younger athletes should consider a creatine supplement under certain conditions: puberty is past and he/she is involved in serious competitive training; the athlete is eating a well-balanced caloric adequate diet; he/she as well as the parents approve and understand the truth concerning the effects of creatine supplementation; supplement protocols are supervised by qualified professionals; recommended doses must not be exceeded; quality supplements are administered.

^ "The History of Weightlifting". USA Weightlifting. United States Olympic Committee. Archived from the original on 7 July 2013. Retrieved 3 September 2018. The genealogy of lifting traces back to the beginning of recorded history where man's fascination with physical prowess can be found among numerous ancient writings. A 5,000-year-old Chinese text tells of prospective soldiers having to pass lifting tests.
Put simply, "strength training means using resistance to create work for your muscles," says Hannah Davis, C.S.C.S. and author of Operation Bikini Body. So even if your mind jumps straight to those hardcore machines and massive weights, there are a lot of ways to create this resistance that require minimal equipment (or none at all). Bodyweight workouts can be an incredibly effective way to strength train. Squats and push-ups FTW. You can also use tools like dumbbells, medicine balls, TRX bands, resistance bands, kettlebells, and slider disks, to help get the job done, explains Davis. But if that sounds like gibberish don't worry about it. Keep it simple and focus on equipment-free routines first. No matter what you do, the most important thing is to find something that challenges you, says Davis.

Supplementation of creatine at 5g daily alongside rehabilitation (after limb immobilization for two weeks while taking 20g daily) is associated with a preservation in GLUT4 levels, which were reduced during immobilization. During exercise rehabilitation, it increased to 40% above placebo.[330] This study failed to note an increase in GLUT4 in control, despite exercise normally doing so.[331][332] This effect is thought to be the result of the low frequency of activity. Thus, creatine was thought to augment the increase (insignificant due to low exercise) to significant levels.[330] In other studies, creatine was found to increase GLUT by approximately 30% relative to control, but this effect failed to reach statistical significance. This study did not issue an exercise protocol.[207]


1. Are you tracking calories? Doesn't have to be religiously but one should have a general idea of where they're at if the goal is mass gain and things have stalled. I'm not talking about weighing every gram of food you put in your mouth and meticulously logging your life on MyFitnessPal. As long as you're aware (within 100-200 calories) of what's going in, you should have an idea of what to adjust.
In regard to practical interventions, concurrent glycogen loading has been noted to increase creatine stores by 37-46% regardless of whether the tissue was exercised prior to loading phase.[176] It is important to note, however, that creatine levels in response to the creatine loading protocol were compared in one glycogen-depleted leg to the contralateral control leg, which was not exercised.[176] This does not rule out a possible systemic exercise-driven increase in creatine uptake, and the increase in creatine noted above[176] was larger than typically seen with a loading protocol (usually in the 20-25% range). Consistent with an exercise-effect, others have reported that exercise itself increases creatine uptake into muscle, reporting 68% greater creatine uptake in an exercised limb, relative to 14% without exercise.[153]

If you’re a beginner, you should train with three full-body workouts per week. In each one, do a compound pushing movement (like a bench press), a compound pulling movement (like a chinup), and a compound lower-body exercise (squat, trap-bar deadlift, for example). If you want to add in 1–2 other exercises like loaded carries or kettlebell swings as a finisher, that’s fine, but three exercises is enough to work the whole body.


One pilot study using 150mg/kg creatine monohydrate for a five day loading phase followed by maintenance (60mg/kg) for the remainder of the five weeks noted that supplementation was associated with fewer muscle symptoms and complaints alongside improved muscular function,[572] yet a later trial trying to replicate the obsevations using 150mg/kg daily for five weeks noted the opposite, that creatine supplementation exacerbated symptoms.[573] 
There is a nuclear receptor known as TIS1 (orphan receptor, since there are no known endogeouns targets at this time) which positively influences transcription of new creatine transporters[171] and, in C2C12 myotubes, seems to be responsive to cAMP or adenyl cyclase stimulation from forskolin (from Coleus Forskohlii) with peak activation at 20µM.[171][172] 
Arguably the most influential factor, exercise is what instigates muscle growth. When you exercise, especially if you engage in resistance training, it causes trauma to your muscles. This is exactly what you want because it’s this trauma that triggers a response from your body that grows your muscles. To repair the injury or damage to your muscles, special cells called satellite cells arrive. Typically, your muscle fibers thicken and lengthen in this process. (1)

Creatine supplementation in the under 18 population has not received a great deal of attention, especially in regards to sports/exercise performance. Despite this, creatine is being supplemented in young, <18 years old, athletes [52,53]. In a 2001 report [52] conducted on pupils from middle and high school (aged 10 – 18) in Westchester County (USA) 62 of the 1103 pupils surveyed were using creatine. The authors found this concerning for 2 main reasons: firstly, the safety of creatine supplementation is not established for this age group and is therefore not recommended. Secondly, it was speculated that taking creatine would lead on to more dangerous performance enhancing products such as anabolic steroids. It is important to point out that this potential escalation is speculation. Furthermore, a questionnaire was used to determine creatine use amongst this age group and does not necessarily reflect the truth.

Lung disease (Chronic obstructive pulmonary disease). Early research on the effects of creatine in people with chronic obstructive pulmonary disease (COPD) is inconsistent. Some research suggests that taking creating daily does not improve lung function. However, other research suggests that taking creatine may improve lung function or exercise capacity.
When creatine is absorbed it pulls water in with it, causing cells to swell. This “cell volumization” is known to promote a cellular anabolic state associated with less protein breakdown and increased DNA synthesis.[107][108][109] An increase in cellular viability assessed via phase angle (measuring body cell mass[110]) has been noted in humans during supplementation of creatine.[111]
Having a spotter nearby is particularly important when using free weights. Even someone in great shape sometimes just can't make that last rep. It's no big deal if you're doing biceps curls; all you'll have to do is drop the weight onto the floor. But if you're in the middle of a bench press — a chest exercise where you're lying on a bench and pushing a loaded barbell away from your chest — it's easy to get hurt if you drop the weight. A spotter can keep you from dropping the barbell onto your chest.

Creatine is found in many protein supplements at baseline in the form of creatine monohydrate. If you take a protein supplement, you may already be getting creatine. What makes this creatine so special? Like the protein supplement above, this creatine supplement contains no artificial sweeteners or dyes. It contains 5000mg of creatine per dose and includes certain compounds to increase the bioavailability of the creatine, allowing it to be better absorbed.


Focus on form. Good form means you can reap all of the benefits of your workout and avoid injuries at the same time. To maintain proper form, pay attention to your posture (stand tall with chest lifted and abs held tight), move slowly (this ensures you're relying on muscles, not momentum, to do the lifting), and remember to breathe. Many people hold their breath while exerting, but exhaling during the hardest part of the exercise helps fuel the movement.
After all, you’ve probably seen the countless workouts, diets, supplements, programs, products and people claiming that super fast muscle growth is possible. You’ve probably also seen the click-bait headlines (“How To Build 20lbs Of Muscle In Just 6 Weeks!”) and the unbelievable transformations of supposedly “natural” people (bodybuilders, celebrities, athletes, fitness gurus on social media, etc.) that clearly prove it can happen faster than this.

The bodybuilding community has been the source of many weight training principles, techniques, vocabulary, and customs. Weight training does allow tremendous flexibility in exercises and weights which can allow bodybuilders to target specific muscles and muscle groups, as well as attain specific goals. Not all bodybuilding is undertaken to compete in bodybuilding contests and, in fact, the vast majority of bodybuilders never compete, but bodybuild for their own personal reasons.
Cyclocreatine (1-carboxymethyl-2-iminoimidazolidine) is a synthetic analogue of creatine in a cyclic form. It serves as a substrate for the creatine kinase enzyme system, acting as a creatine mimetic. Cyclocreatine may compete with creatine in the CK enzyme system to transfer phosphate groups to ADP, as coincubation of both can reduce cyclocreatine’s anti-motility effects on some cancer cells.[96]
It is equally important, if not more so, to ensure that you supply your body with more protein than it is breaking down each day. Your body uses protein for many things daily, and when you are working out, your body may start to break down proteins to provide extra energy. But your body also requires proteins to create new muscle cells and repair damaged ones. Many bodybuilding supplements contain large amounts of protein to ensure that your body has plenty for all required processes. Jump to Our 10 Best Bodybuilding Supplement List
Of course, cardio is an important part of fitness too, but the benefits of strength training are major. Strength training helps build muscle, and lean muscle is better at burning calories when the body is at rest, which is important whether you're trying to lose weight or maintain it. It also helps strengthens joints and bones, avoid injury, improve your muscular endurance, and will help you give it your all during your other workouts, whether that means setting a new PR if you're a runner or pushing (and pulling) a little harder with your legs during your favorite indoor cycling class.
Weight training has also been shown to benefit dieters as it inhibits lean body mass loss (as opposed to fat loss) when under a caloric deficit. Weight training also strengthens bones, helping to prevent bone loss and osteoporosis. By increasing muscular strength and improving balance, weight training can also reduce falls by elderly persons. Weight training is also attracting attention for the benefits it can have on the brain, and in older adults, a 2017 meta analysis found that it was effective in improving cognitive performance.[38]

While muscle growth is critical for bodybuilding, getting rid of extra fat is a necessity to improve your total physique. These supplements can help to increase your metabolism, forcing your body to burn away more of its fat stores. They can also slow down the digestion process to prevent excess fat and carbohydrates from entering the body and being stored.
“Reg Park’s theory was that first you have to build the mass and then chisel it down to get the quality; you work on your body the way a sculptor would work on a piece of clay or wood or steel. You rough it out””the more carefully, the more thoroughly, the better”” then you start to cut and define. You work it down gradually until it’s ready to be rubbed and polished. And that’s when you really know about the foundation. Then all the faults of poor early training stand out as hopeless, almost irreparable flaws. [..]
There are a number of weight machines that are commonly found in neighborhood gyms. The Smith machine is a barbell that is constrained to vertical movement. The cable machine consists of two weight stacks separated by 2.5 metres, with cables running through adjustable pulleys (that can be fixed at any height so as to select different amounts of weight) to various types of handles. There are also exercise-specific weight machines such as the leg press. A multigym includes a variety of exercise-specific mechanisms in one apparatus.
Oral ingestion of 1-1000mg/kg bodyweight of creatine in mice was able to exert an anti-depressive effect, which was blocked by dopamine receptor antagonists. A low dose of creatine (0.1mg/kg) was able to enhance the dopaminergic effects of dopamine receptor activators, suggesting supplemental creatine can positively influence dopamine signaling and neurotransmission.[252]
Take time to rest. To give your muscles time to recover, rest one full day between exercising each specific muscle group. You might choose to work the major muscle groups at a single session two or three times a week, or plan daily sessions for specific muscle groups. For example, on Monday work your arms and shoulders, on Tuesday work your legs, and so on.
Perform bent over rows to work your back. Stand with your feet shoulder-width apart, about 6 to 10 inches (15–25 cm) behind the barbell or two dumbbells. Bend slightly at the knees but keep your shins vertical. Bend forward at the waist with your spine and head straight. Lift the weight with an overhand grip up to your lower chest or upper abdomen. Lower slowly until your arms are nearly extended, without touching the ground. 3 x 8.[5]
Translation: your muscles are going to have more energy. The process of accessing that energy is so complicated, you almost need an organic chemistry degree to totally understand it. Yes, it’s complicated, but completely necessary for biochemical reactions like muscle contractions. And the more your muscle works, the more ATP is depleted and needs to be replaced for you to make progress toward your goals. With creatine supplementation, you can enhance your ATP regeneration and thus delay onset of muscle fatigue and work more intensely for a longer period of time. Little goes a long way in the pursuit of muscle gains.
Recommended dose: The fastest way to increase muscle creatine stores is to follow the loading method of 20 grams per day for 5-7 days, followed by the standard maintenance dose of 5 grams per day. However, a lower dose of 5 grams for 28 days will also increase creatine stores without causing the 2-4 pound weight gain typically seen with a loading protocol.
Prohormones are precursors to hormones and are most typically sold to bodybuilders as a precursor to the natural hormone testosterone. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen. To deal with this, many supplements also have aromatase inhibitors and DHT blockers such as chrysin and 4-androstene-3,6,17-trione. To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown. Although initially available over the counter, their purchase was made illegal without a prescription in the US in 2004, and they hold similar status in many other countries. They remain legal, however, in the United Kingdom and the wider European Union. Their use is prohibited by most sporting bodies.
When you're in the middle of a strength-training session and something doesn't feel right to you, you feel pain, or if you hear or feel a "pop" during a workout, stop what you're doing. Have a doctor check it out before you go back to training. You may need to change your training or even stop lifting weights for a while to allow the injury to heal.

"Start with two days for two to three weeks, then add a third day," says Davis*.*"Ideally, you should strength train three to five days per week, but work your way up—starting off at five days a week might shock your body." Here's a comprehensive three-day-per-week plan to get you started. Aim to complete 20-minute sessions, then gradually add on time in ten-minute increments until you're working for 45 to 60 minutes, suggests Davis.
Moreover, the Food and Drug Administration (FDA) has identified numerous products marketed as bodybuilding or muscle-building dietary supplements that contain hidden active ingredients, including prescription drugs and steroid and steroid-like ingredients. Not only do these ingredients pose serious health risks, they might cause you to pop positive on a drug test. The only way to be sure a product contains only what’s on the label is to look for one that has been evaluated by an independent, third-party organization. For more information, visit FDA’s Consumer Update about bodybuilding products.
Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost (relative to meat and fish products), ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats. Additionally, some argue that bodybuilders, by virtue of their unique training and goals, require higher-than-average quantities of protein to support maximal muscle growth.[19][20][21][22][23][24][25] However, there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance.[18][26] Protein supplements are sold in ready-to-drink shakes, bars, meal replacement products (see below), bites, oats, gels and powders. Protein powders are the most popular and may have flavoring added for palatability. The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:

Weight training is also attracting attention for the benefits it can have on the brain, and in older adults, a 2017 meta analysis found that it was effective in improving cognitive performance.[38]
If you have been training properly for at least three years, you’ll find that advanced pump-enhancing techniques like rest-pause sets, drop sets, and some of the other old-school bodybuilding techniques you’ve no doubt heard of can be effective when used sparingly. Just be sure not to overdo the use of them. And never get away from the most important rule: setting PR’s to get stronger.
Negative regulators of the creatine transporter (CrT) are those that, when activated, reduce the activity of the CrT and overall creatine uptake into cells. As noted above, CrT activity is positively regulated by mTOR.[158] Consistent with the well-known role of AMPK as a suppressor mTOR signaling,[177] CrT activity has also been shown to be inhibited in response to AMPK activation in kidney epithelial cells.[178] Since AMPK suppresses mTOR via upstream TSC2 activation,[179] the negative regulation of AMPK on CrT activity in these cells appears to occur through an indirect mechanism. Although indirect, activation of AMPK has been noted to reduce the Vmax of the CrT without altering creatine binding, and is involved in internalizing the receptors.[178] This pathway seems to max out at around 30% suppression, with no combination of mTOR antagonists and AMPK inducers further suppressing creatine uptake.[178]
If you’re the kind of person who shops for popular dietary supplements like protein or collagen powder, you’ve probably seen another popular bottle on the shelves: creatine. This supplement, which can be taken as a powder or liquid (and usually in some kind of healthy shake), is a staple in the bodybuilding community thanks to its ability to help you pack on muscle and work out longer and harder. (1) While creatine is generally considered safe — and is one of the most researched supplements out there (according to a review published in July 2012 in the Journal of the International Society of Sports Nutrition) — it is still a supplement, which means it’s not regulated by the Food and Drug Administration (FDA) and product claims don’t necessarily need to be substantiated (though the FDA can pull products that are found to be unsafe). (2,3)
You may have heard hardcore lifters talk about things like "leg day," but when it comes to a beginner strength workout that's only a few days a week, a full-body workout is often the way to go (rather than splitting your days up by body part). "Full-body workouts maximize your caloric burn and the muscles worked each session," says Davis. The best way to do this is to pair one upper body exercise with one lower body exercise. "This way, the lower body has time to recover while the upper body works and vice-versa," says Davis. You should also aim for a balance between movements that feel like pulling and ones that feel like pushing. For example, Davis suggests pairing these exercises together:
First off, every single resistance-training athlete in the world should be very thankful for bodybuilding training. It was bodybuilding that brought weight training to the mainstream. The bottom line is that the average gym goer is MORE interested in how they look vs. how they perform. 99% of every client I ever trained had an aesthetic goal as their primary goal. In my 20 plus years as a trainer I can count maybe 10 clients who said, “My goal is to be able to bench press or squat or lift more weight.” It was the aesthetic focus of bodybuilding that opened the doors for all other resistance training pursuits to enter into the mainstream.
A child’s ability to regenerate high energy phosphates during high intensity exercise is less than that of an adult. Due to this, creatine supplementation may benefit the rate and use of creatine phosphate and ATP rephosporylation. However, performance in short duration high-intensity exercise can be improved through training therefore supplementation may not be necessary [54].
All you need to know about low creatinine levels Creatinine is a waste material in the body, and low levels can suggest a shortfall in liver function or activity. This MNT Knowledge Center feature looks at low creatinine levels., as well as information on what creatinine is, how it affects the body, and how to increase low creatinine levels. Read now
Different forms of creatine in combination with other sports supplements as well as varying doses and supplementation methodology should continue to be researched in an attempt to understand further application of creatine to increase sports and exercise performance of varying disciplines. It is important to remain impartial when evaluating the safety of creatine ingested as a natural supplement. The available evidence indicates that creatine consumption is safe. This perception of safety cannot be guaranteed especially that of the long term safety of creatine supplementation and the various forms of creatine which are administered to different populations (athletes, sedentary, patient, active, young or elderly) throughout the globe.
Despite the fact that BCAAs may offer some benefits, you should keep in mind that these three amino acids are also present in any quality whey protein that you purchase. You can also get these essential amino acids from food sources. Basically, as long as you’re meeting your daily protein intake goals, you’re probably getting enough of these essential amino acids. Research supports this approach. So, why spend more on another supplement?

GLUTs are vesicle transporters that are the rate-limiting steps for bringing glucose into a cell, and GLUT4 is the most active variant.[327] Agents that reduce blood glucose (insulin or AMPK) are known to act via mobilizing GLUT4, and increased GLUT4 expression and activity is indicative of a greater ability to bring glucose into a cell, while reducing it impairs glucose uptake.[328] Rat studies have confirmed that creatine feeding increases muscular GLUT4 expression associated with increased insulin-stimulated glucose uptake.[329]
Genetic deficiencies in the creatine biosynthetic pathway lead to various severe neurological defects.[26] Clinically, there are three distinct disorders of creatine metabolism. Deficiencies in the two synthesis enzymes can cause L-arginine:glycine amidinotransferase deficiency caused by variants in GATM and guanidinoacetate methyltransferase deficiency, caused by variants in GAMT. Both biosynthetic defects are inherited in an autosomal recessive manner. A third defect, creatine transporter defect, is caused by mutations in SLC6A8 and inherited in a X-linked manner. This condition is related to the transport of creatine into the brain.[27]
