collagen formation with glycine

Collagen is the most superabundant protein in the human body and is a critical component of the extracellular matrix, which supplies structural support to cells and tissues. When a wound occurs, the body immediately initiates a cascade of events to repair the damaged tissue. One of these events is the deposition of new collagen to replace the damaged tissue. Glycine is a critical component of collagen; therefore, it is vital for the growth and repair of skin, bones, and other tissues.

Numerous studies have shown that supplementing with glycine can promote the healing of wounds, including burns and ulcers. For example, research published in the Journal of Burn Care and Rehabilitation found that glycine supplementation significantly improved wound healing in burn-injury patients. Another study published in the Journal of Clinical Investigation found that glycine supplementation accelerated the healing of diabetic foot ulcers.
