NOW Glycine 1000mg - 100 Free-Form Veg Capsules
NOW Glycine 1000mg provides pure, free-form, pharmaceutical-grade glycine — the smallest and simplest amino acid. Each serving of 3 vegetarian capsules delivers 3,000mg (3g) of glycine with no fillers beyond the capsule excipients. Available in 100 and 250 capsule sizes from Probiotic.ie.
Glycine is found naturally in collagen, connective tissue, and protein-rich foods. As a free-form supplement it is absorbed directly without requiring digestion to break peptide bonds. Pharmaceutical-grade purity means it is manufactured to stricter quality specifications under GMP-certified conditions.

What is Glycine?
Glycine is the smallest and simplest of the 20 standard amino acids. Unlike many amino acids, it has no side chain — its molecule consists of just an amino group, a carboxyl group, and a hydrogen atom. This structural simplicity makes it highly versatile as a building block in biological systems.
It is classified as a non-essential amino acid, meaning the body can synthesise it endogenously. It is also obtained through dietary sources, particularly foods rich in collagen and connective tissue such as bone broth, meat, and fish. Glycine is found in high concentrations in skin, cartilage, and other connective tissues.
As a component of proteins, glycine is involved in the synthesis of collagen, glutathione, creatine, bile salts, and haemoglobin. It is also an inhibitory neurotransmitter in the central nervous system.
Free-Form and Pharmaceutical Grade: What It Means
Free-form means the glycine is in its unbound, pure amino acid state — not incorporated into a protein chain or bound to another compound. Free-form amino acids do not require enzymatic digestion to break peptide bonds before absorption.
Pharmaceutical grade means the glycine used in this product meets higher purity and quality specifications than standard food-grade ingredients. It is manufactured under GMP (Good Manufacturing Practice) conditions with testing for potency, identity, and contaminants.
Most glycine supplements on the market are either food grade or do not specify grade. NOW specifies pharmaceutical-grade free-form glycine — a meaningful quality distinction at the 3,000mg serving size.
