Supplement Description

What is L-Lysine? 

Lysine is an essential amino acid, which means that the human body cannot synthesise it.

Why take L-Lysine?

Amino acids are critical to life, and have many functions in metabolism. One particularly important function is to serve as the building blocks of proteins, which are linear chains of amino acids. Amino acids can be linked together in varying sequences to form a vast variety of proteins.

L-Lysine is a necessary building block for all protein in the body.
