Generally speaking, high dose amino acid supplements, utilizing pure amino acid sources. While a chicken breast, or handful of peanuts may contain similar amounts of some of these amino acids, getting them in a proper ratio is very important (from what I've been told by experts in this field). There is a strong body of evidence that BCAA (leucine, valine, isoleucine) are metabolized by skeletal muscle in order to meet increased energy demands during exercise. BCAAs may also participate in inhibiting central nervous system fatigue (mental tiredness).
I still don't know what dosage of amino acids is the best to use for exercise, but generally you see between 1-5 mg as a general amount of mixed or pure amino acid. 5 mg is a lot! Remember, more is NOT always better, especially because it is important to get the proper ratios.
Other amino acids such as alpha-ketoglutarate, glutamine, ornithine, and taurine have more speculative roles that are perhaps less proven/researched.

| There exists evidence that by encouraging intramuscular carnosine synthesis beta-alanine supplementation results in lactic acid buffering within the muscle cells and perhaps increasing VO2 max under certain test conditions. Generally thought to be more important for sprint or anaerobic workouts that generate a lot of lactic acid, recent evidence suggests there may also be some benefit for endurance athletes. This particular supplement could have its very own blog. |
