The human body may not synthesize enough glycine on average diets to meet metabolic needs, including collagen and glutathione synthesis.

“Ideally, you should be able to use glycine to make your own collagen.”

“and that in people like in France they usually only got one and a half to three grams a day in addition to that they thought that that sit four and a half to six grams a day at glycine was falling significantly short of what was needed for all metabolic uses including collagen synthesis and making glutathione would probably be equally important in the human body”

“so the study is so this is one of the studies that I talked about a weak link in metabolism the metabolic capacity for glycine biosynthesis does not satisfy the need for collagen synthesis”

“the research is pretty strongly indicating that we can't synthesize enough of it so we basically have a cap of a few grams of glycine that we can synthesize and we fall short of our glycine needs by 10 to 60 grams a day”

“glycine is a critical amino acid for collagen those doesn't critical massive amino acids including the thione and most people who are not in this room who are living normal lives in society don't get enough lysine because they don't get enough amino acids because they don't have protein”

“the average person probably should fall short of their ability to synthesize glycine by 10 to 60 grams a day in terms of optimizing collagen turnover in the skin and etc etc etc”
