Glycine is a nonessential amino acid used by the body to build proteins. It is present in considerable amounts in prostate fluid.

Glycine may play a role in maintaining the health of the prostate, since a study of 45 men with benign prostatic hyperplasia (BPH) found that 780 mg of glycine per day for two weeks and then 390 mg for the next two and a half months, taken in combination with equal amounts of the amino acids, alanine and glutamic acid, reduced symptoms of the condition.1 This effect has been reported by others.2 Glycine also enhances the activity of chemical messengers (neurotransmitters) in the brain that are involved in memory and cognition.3

Suitable for vegans.
