Bulk Glycine Powder

by Bulk

GMP Third-Party Tested

Pure glycine powder in a 500g pouch from the UK's leading sports nutrition retailer. Unflavoured and additive-free, designed for flexible dosing and easy mixing. A slightly larger quantity than NOW Foods at a competitive UK price. Popular among gym-goers for sleep recovery and as an ingredient in homemade pre-sleep blends.

AI Review Summary

Bulk's Glycine Powder offers the same pure amino acid as NOW Foods in a larger 500g quantity at a lower UK price. The sensible 3g serving size matches the clinical dose, unlike NOW's 1g label serving. Quality is comparable — pure glycine is pure glycine regardless of brand. The main advantage is price; the main disadvantage is the pouch packaging versus a rigid tub.
