Seems like there is a mistake in the label, but it is interesting all the people claiming "muhh low leucine =bad for muscle protein synthesis" when in fact the blend allows for a much more balanced amino acid profile for optimal health. The specific ratio that comes up in the literature is roughly 1:1 methionine to glycine. But essentially most people consume far too much methionine relative to glycine and would likely benefit from this blend. Methionine is abundant in muscle meat, eggs, and dairy. Glycine is abundant in connective tissue, skin, bones, and organs, which modern diets almost entirely exclude. Excess methionine without adequate glycine drives elevated homocysteine (methionine's primary metabolic byproduct, also used as a cardiovascular risk factor). It will also deplete glycine pools, since glycine is one of the substrates used to clear homocysteine via the transsulfuration pathway. Probably reduced glutathione synthesis (glycine + cysteine + glutamate) as well. Most people are short 5-10g of glycine per day just from eating muscle meat exclusively. So actually I kinda like @paulsaladinomd 's bar, doesn't replace normal meals but that was never the point and all the carnivores using this argument are just straw-manning.
