Some people do have allergies to soy, or they have an intolerance to soy. If you notice certain symptoms (like a headache) after soy consumption, you may have an intolerance. Discovering your food intolerances/allergies would also be handled by a Dietitian. For the general population who are not allergic/intolerant to soy, however, soy-based products can be a part of a healthy diet. New research has shown that soy is not harmful as people fear. If soy gives you issues, you could always opt for whey protein, pea protein or other forms of vegetable protein. Have you seen our article on protein powders? Click here.
An exercise should be halted if marked or sudden pain is felt, to prevent further injury. However, not all discomfort indicates injury. Weight training exercises are brief but very intense, and many people are unaccustomed to this level of effort. The expression "no pain, no gain" refers to working through the discomfort expected from such vigorous effort, rather than to willfully ignore extreme pain, which may indicate serious soft tissue injuries. The focus must be proper form, not the amount of weight lifted.[23]
Creatine may preserve dopamine synthesis in the striatum of mice (while protecting against dopaminergic depletion) when fed to mice at 2% of the diet for one week prior to MPTP toxicity[230]. This is possibly secondary to increasing tyrosine hydroxylase activity, the rate-limiting step of dopamine biosynthesis.[210][235] Two percent creatine was as protective as 0.005% rofecoxib (a COX2 inhibitor), but the two were additive in their protective effects (highly synergistic in regard to DOPAC by normalizing it, but not synergistic in preserving HVA).[230]

Creatine, through its ability to act as an energy reserve, attenuates neuron death induced by the MPTP toxin that can produce Parkinson’s disease-like effects in research animals,[235] reduces glutamate-induced excitotoxicity,[236] attenuates rotenone-induced toxicity,[120] L-DOPA induced dyskinesia,[237] 3-nitropropinoic acid,[238] and preserves growth rate of neurons during exposure to corticosteroids (like cortisol), which can reduce neuron growth rates.[239] Interestingly, the energetic effect also applies to Alzheimer’s disease, during which creatine phosphate per se attenuates pathogenesis in vitro, yet creatine per se did not.[240]


Recommended Dose: 3-6 grams before or during exercise. A ratio of two parts leucine to one part each of isoleucine and valine appears to be most beneficial. As Krissy Kendall, PhD, explains in "The Top 7 Supplements to Boost Endurance Performance," BCAAs can be just as effective for endurance athletes like runners, rowers, and cyclists as they can be for lifters and bodybuilders.
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 you’re doing higher reps, focus on the muscle you are trying to build and squeeze every ounce of effort out of it. Yes, cheesie as it may sound, visualizing the muscles working and growing while you train them can be helpful. A 2016 study in the European Journal of Applied Physiology found that, when lifters thought about their pecs and triceps during a workout, they activated them better.

Three amino acids (glycine, arginine and methionine) and three enzymes (L-arginine:glycine amidinotransferase, guanidinoacetate methyltransferase and methionine adenosyltransferase) are required for creatine synthesis. The impact creatine synthesis has on glycine metabolism in adults is low, however the demand is more appreciable on the metabolism of arginine and methionine [11].
Heath has 1.8 million Instagram followers, 300,000 Twitter followers, a global fan base and a growing portfolio of muscle magazine covers. He competes in just one competition a year, Mr. Olympia, for which he won the $400,000 first prize this year. He spends the rest of the year staying in shape and flying hundreds of thousands of miles for appearances, conferences and meetings. He has five sponsors, led by Ultimate Nutrition, a supplement company. All told, he earns more than $1 million a year, his agent said.
It is regularly reported that creatine supplementation, when combined with heavy resistance training leads to enhanced physical performance, fat free mass, and muscle morphology [18-22]. A 2003 meta analysis [8] showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups. However, contradicting studies have reported no effects of creatine supplementation on strength performance. Jakobi et al [23] found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process. However, this study did not clearly state if creatine supplementation was administered concurrent with resistance training. Bemben et al [24] have shown no additional benefits of creatine alone or combined with whey protein for improving strength and muscle mass after a progressive 14 weeks (3 days per week) resistance training program in older men. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only (3 times a week). This strategy has not been adequately tested as effective in middle aged and older men for maintaining post loading elevated creatine stores [5].

So it was popular then, but is it effective now? Just because something is popular doesn’t mean it works. In the case of creatine supplementation, however, you can be confident that increased muscle strength and less fatigue is possible. All thanks to a critical chemical reaction taking place in your muscle cells. Read on and learn how creatine works and why it lives up to that nostalgic ‘90s hype.

Several studies have used either beet root juice or pomegranate extract in multi-ingredient performance supplements and have observed improvements in strength, hypertrophy, and performance in resistance-trained men. At this point, however, it's difficult to determine if these benefits are from beet root juice and pomegranate extract working alone or synergistically with other ingredients.[11,12]
In regard to bioenergetics, phosphorylated cyclocreatine appears to have less affinity for the creatine kinase enzyme than phosphorylated creatine in terms of donating the high energy phosphate group (about 160-fold less affinity) despite the process of receiving phosphorylation being similar.[104][105] When fed to chickens, phosphorylated cyclocreatine can accumulate up to 60mM in skeletal muscle,[106] which suggests a sequestering of phosphate groups before equilibrium is reached.[105] Cyclocreatine still has the capacity to donate phosphate, however, as beta-adrenergic stimulated skeletal muscle (which depletes ATP and glycogen) exhibits an attenuation of glycogen depletion (indicative of preservation of ATP) with phosphocreatine.[102]
Multivitamin supplements may help you reach the recommended daily intakes for vitamins and minerals if you have a less than ideal diet, travel impairs your diet, or strenuous exercise increases requirements. I consider a multivitamin good insurance in these circumstances against possible deficiencies. Choose a reputable brand. You should choose a good all-around supplement with a balanced formula.

Pick a few key exercises that together train the whole body. Presses, chinups, rows, and squat and deadlift variations are the best choices (more on these in Rules #2 and #3). Write down how much weight you can currently do for 5–10 reps on each of them, and, over the next few months, work your way up to where you can either add 10–20 pounds to each of those lifts or do 3–5 more reps with the same weight. That’s how you force your body to grow.

Creatine is a powerful supplement for strength and muscle gain. It always recommended utilize creatine before the workout. It gives you the strength and power of more repetition. With creatine, you can also use SR-9009. SR-9009 has the capabilities of lowering obesity and reversing metabolic syndrome. SR-9009 allows to perform more cardio training, weight loss, improve cholesterol levels, and gain lean muscle mass. Hope this information will help someone.


Synthesis primarily takes place in the kidney and liver, with creatine then being transported to the muscles via the blood. The majority of the human body's total creatine and phosphocreatine stores is located in skeletal muscle, while the remainder is distributed in the blood, brain, and other tissues.[17][18][20] Typically, creatine is produced endogenously at an estimated rate of about 8.3 mmol or 1 gram per day in young adults.[16][17] Creatine is also obtained through the diet at a rate of about 1 gram per day from an omnivorous diet.[17][18] Some small studies suggest that total muscle creatine is significantly lower in vegetarians than non-vegetarians, as expected since foods of animal origin are the primary source of creatine. However, subjects happened to show the same levels after using supplements.[21]
