Amino acids (AAs) are available as individual AAs or in AA combinations. They also come as part of multi-vitamins, proteins, and food supplements. The forms include tablets, fluids, and powders.
Note that by eating enough protein in your diet, you get all of the amino acids you need.
There are no conditions that increase how much glycine you need.
Using a single amino acid supplement may lead to negative nitrogen balance. This can decrease how efficient your metabolism is. It can also make your kidneys work harder. In children, taking single amino acid supplements may also cause growth problems. It may also cause seizures and developmental delays.
You should not take high doses of individual amino acids for long periods of time.
Women who are pregnant or breastfeeding shouldn’t use glycine supplements.
