Amino acids are the building blocks of protein, they aid in the growth and repair of muscle tissue, and also stop the breakdown of muscle. Amino acids also help regulate moods and healthy sleep. In essence without having an abundance of amino acids on a daily basis your muscles will not grow and indeed your body will not function properly.

Amino acid supplements come in various different forms, firstly supplements that contain all aminos, secondly individual aminos and thirdly BCAAs that contain leucine, isoleucine and valine (essential aminos). BCAAs are important for athletes as they are metabolised in muscle, however just because some aminos are non-essential make sure you attain these from your diet as well – having all amino acids in your body is large enough quantities is vital for muscle growth, development and preservation.

L-Glutamine is also popular as it is the most abundant free form amino found in muscle tissue - hence the link to muscle repair and recovery. Supplementing with L-Glutamine will make sure none of the glutamine found in muscle tissue will be used for other sources, ensuring glutamine can do its job uninterrupted.

HMB is also becoming very popular for its muscle sparing and muscle building capacity. HMB, short for beta-hydroxy beta-methylbutyrate is a metabolite of leucine, one of the branched chain amino acids, and also an essential amino acid. Studies show that HMB can increase strength and muscle mass over control groups. Other studies show that HMB works by increasing the amount protein that can be used by the body, whilst simultaneously preventing muscle breakdown.
