Methionine-Glycine Balance

Glycine supplementation may help people with lean-meat-heavy, collagen-poor diets by restoring a more natural methionine-glycine balance. Modern diets are often high in methionine-rich muscle meats and low in glycine-rich animal tissues. A high-methionine, low-glycine pattern can increase metabolic processing concerns because methionine metabolism generates homocysteine and related compounds. Traditional whole-animal eating patterns included collagen-rich tissues that supplied more glycine.
