Glycine is a part of creatine, which transforms adenosine diphosphate, ADP, into adenosine triphosphate, ATP.  When ATP is broken down energy is released and this powers all of our body processes including muscle contraction.

Creatine also helps to construct our genetic material, DNA and RNA.  Glycine is used to synthesize other amino acids, bile acids (for fat digestion) and connective tissue (for healing the skin).  It is often added to commercial antacids because of its ability to decrease stomach acidity.  As a neurotransmitter, a brain chemical that regulates the electrical conduction of the brain, glycine stops brain cells from overfiring.  Thus it relaxes the mind and body.  Glycine can be supplemented to help with the following health concerns: hyperactivity, bipolar disorder, epilepsy, muscle weakness, indigestion, heartburn, fatigue and poor wound healing.

Glycine is usually supplemented as L-glycine.  L-glycine is found in capsules, tablets or cream.  It is best absorbed when taken between meals.    If you take an individual amino acid supplement for longer than one month, take it with an amino acid complex to prevent the deficiency of other amino acids.  Glycine cream can be applied topically for wound healing.  Glycine can also convert into serine if vitamins B3, B6 and folic acid are present.

A balance of glycine is needed for optimal health and energy enhancement.  Too much glycine actually causes fatigue.
