                                Multiple clinical studies have evaluated glycine dosages ranging from 3 to 15 grams per day and have found them to be generally safe for most people. A 1000 mg (1 gram) dose of glycine is significantly lower than these studied amounts, making it well within the range considered safe for typical supplementation.
