STATEMENT: Glycine aids in diabetic ulcer, stroke prevention and liver health
TITLE: 17 Benefits of Glycine Supplements and Dietary Supplements
The richest dietary sources of glycine include fish, gelatin and all types of meat.
20-30% of glycine is found in Collagen
Glycine (through the consumption of collagen) significantly improved skin elasticity in elderly women and improved skin moisture and water loss [4, 5].Collagen peptide, which contains a lot of glycine, suppressed UV-B induced skin damage and photoaging .Women taking 2.5g of collagen peptide for 4 weeks significantly reduced eye wrinkles by 20%, with positive effects lasting after the study ended .At 8 weeks, collagen significantly improved skin content of procollagen type I by 65%, and elastin by 18%.
Glycine nearly doubles the speed at which skin ulcers heal in 89 diabetic patients across 23 long term care facilities .Glycine enhanced wound healing in diabetic animal models as well .Glycine in combination with l-cysteine and dl-threonine topically applied to leg ulcerations significantly improved the degree of wound healing and decreased pain .
In ischemic stroke patients, taking glycine 1 – 2g/day normalized autoantibodies, reduced glutamate and aspartate levels, increased GABA concentrations, and reduces lipid peroxidation .Those who consume regularly low doses of glycine actually reduce damage in future strokes .The glycine treatment at the dose of 1 – 2g/day was accompanied by a tendency to a decreased risk of dying over 30-days .
Glycine prevents lactate dehydrogenase leakage (a cell death indicator) in rat liver cells in test tubes .In rats with alcohol poisoning, feeding glycine reduced accumulation of cholesterol, phospholipids, free fatty acids and triglycerides in blood circulation, liver, and brain, ultimately reversing liver disorder associated with fat accumulation .
Glycine supplementation may prove useful for diabetic ulcers, schizophrenia, and stroke recovery. Other human studies suggest a potential benefit for other areas of metabolic and mental health, including insulin resistance, insomnia, and sleep disorders.
