For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit. | |
Who is likely to be deficient?
Few people are glycine deficient, in part because the body makes its own supply of the nonessential amino acids.
How much is usually taken?
Healthy people do not need to supplement with glycine. A physician should be consulted before supplemental glycine is used for the support of serious health conditions.
Are there any side effects or interactions?
No clear toxicity has emerged from glycine studies. However, people with kidney or liver disease should not consume high intakes of amino acids without consulting a healthcare professional.
Are there any drug interactions?
Certain medicines may interact with glycine. Refer to drug interactions for a list of those medicines.
