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]. Sleep Problems People need sleep. It is our basic human need. Too many of...

By ZRT Laboratory.  Most hormones are produced by a group of glands known collectively as the endocrine system. Even though these glands are located in various parts of the body, they are considered one system because of their similar functions and relationship to each other.

Testosterone is non-trivial for social functioning –  increasing levels enhance generosity [1], cooperation [2], and honesty [3], thereby emphasizing that its effects in shaping male psychological makeup are infinitely more complex than previously thought. New Study Points to Altered Consumer Preferences after Testosterone Dosing...
