Amino Acids for Super Humans, Part IV - Purported Ergogenics (3/3): Glutamine, the Anabolic Immune Booster?

Image
Image 1: Still one of the top- sellers in almost all supplement shops - l-glutamine ; tip : buying bulk powder will save money Although glutamine is one of the non-essential amino acids , even the fact that your body continuously 'sacrifices' truly essential amino acids to synthesize glutamine in your muscle tissue, should go to tell you that, after all, glutamine, the most abundant amino acid in human muscle and plasma , cannot be so non-essential as its classification would suggest. Under normal conditions it forms 50% of the whole body amino acid pool. In cells, esp. muscles, where glutamine makes up 66% of the amino acid pool. Within the cellular space, the purported cell-volumizer can reach concentrations that are up to 33 times higher than on the outside of the cell. In times of acute stress, severe burns or surgical trauma, on the other hand, tissue glutamine levels have been observed to decline by up to -50% - ...

Amino Acids for Super Humans, Part IV - Purported Ergogenics (2/3): L-Carnitine, ALCAR, LCLT, GPLC & Co.

Image
Image 1: Even bought in bulk, the carnitines are not exactly cheap, so you better read on to gather whether ALCAR, L-CAR, P-LCAR, L-CLT & Co are worth spending money on. Despite the fact that even my grandmother has heard of the miraculous energizing and fat-burning abilities of carnitine, most people - and even those who are buying those carnitine-enriched functional, or should I say disfunctional foods are not even aware that L-3-hydroxy-4-N,N,N-trimethylaminobutyric acid (l-carnitine) is a naturally occurring amino acid, all mammals (humans included) can synthesize from l-lysine or l-methionine in their livers and kidneys. Necessary co-factors for carnitine synthesis are ascorbic acid (vitamin C),  pyridoxine (vitamin B6),  niacin (vitamin B3) and  S-Adenosyl methionine (SAMe) Interestingly, supplementation of the EAA substrates and co-factors failed to raise carnitine synthesis and or serum levels in respective studies. Gamma-butyrobetaine, ...

Amino Acids for Super Humans, Part IV - Purported Ergogenics (1/3): Beta Alanine, The New Creatine?

Image
Image 1: Despite its presence in meat, fish and dairy, it is near impossible to achieve supra-physiological and thus ergogenic carnosine levels without supplemental beta alanine . Beta alanine, unlike l-alanine is one of the "beta-amino acids", indicating that it is neither essential nor proteinogenic , i.e. it is not built into proteins or used in the synthesis of major enzymes. Nevertheless, beta alanine plays a major role with regard to health in general and brain health and muscular performance , particular. Taken orally, as a supplement, beta alanine (BA) has a slight sweet taste to it ( the artificial sweetener suosan is derived from BA). It is highly water soluble and the funny tingles, which can be avoided by either taking it with food or by taking smaller servings (e.g. 5x 800mg for a total of 4g, which would be a reasonable amount for carnosine "loading") multiple times a day, aside, it is virtually side effects free (some people also de...
