Glycine has a calming effect on the brain – it helps you wind down and prepare for sleep. Its role as an inhibitory neurotransmitter has been unfolding over many years of ongoing research efforts.

Easily one of the most versatile amino acids, glycine serves as a building block to proteins (collagen, the most abundant protein in our body, is one-third glycine), and is heavily utilized for the production of heme, DNA and RNA synthesis, glutathione formation, and for enriching the body’s capacity for methylation reactions [1] [2].

About 20% of our body weight is mitochondria. This translates to about 250 quadrillion of these organelles. There are 37.2 trillion body cells with an average of 1 to 2000 mitochondria per cell. Sperm each have about 16 mitochondria and oocytes have 100,000 (which shows you where the power is).
