General Info

Glycine is readily absorbed from within the small intestine.
Dietary Origins
It is considered to be the most widely available amino acid in the body. The best dietary food sources include fish, meats, and dairy products.

Glycine is an amino acid, a building block of protein. Protein is constructed from a set of twenty amino acids. These amino acids are essential to life and the human body is reliant on proper dietary intake to survive. The underlying cause of many disease not associated with infection is a problem with protein assimilation. Once digested, the amino acids in protein reconfigure to produce muscle and collagen.

Glycine protects ATP-depleted cells by low affinity interactions with multimeric channel proteins. Glycine provided during ATP depletion blocked the development of membranous pores completely. The relationship between necrosis and an extra-cellular depletion of ATP makes its protection and restoration imperative during the prelethal stages of necrosis (non-programmed cell death) or early necrosis.
Toxicities & Precautions

There are no known toxicities associated with glycine.
Side Effects
Taking more than the recommended daily allowance can cause fatigue.

Functions in the Body

Cellular Health
Protects ATP-depleted cells by blocking the development of membranous pores.
Enhance Energy
Proper amounts produce more energy by improving blood-sugar storage.
Nervous System
It is necessary for proper central nervous system function.
Symptoms & Causes of Deficiency
Based on what is known about glycine it may be speculated that a deficiency may cause improper central nervous system function, reduction in energy, and increased risk of free radical damage to cells.
