Proteins are organic molecules made up of amino acids - the building blocks of life. These amino acids are joined together by chemical bonds and then folded in different ways to create three-dimensional structures that are important to many functions in our body. They support everything from the repair, maintenance and growth of muscle tissue to various brain and mood related functions like concentration, sleep and mood to name a few. Our bodies need proteins and amino acids to produce a host of vital molecules in our body like enzymes, hormones, neurotransmitters, and antibodies and so without an adequate protein intake, our bodies can't function properly.

More than 100 amino acids have been found in nature. Of these, 20 are considered "standard amino acids" because they are encoded by the standard genetic code. The 20 "standard amino acids" are further separated into two categories - essential (EAAs) and non-essential. EAAs cannot be produced by the body and must be made available through the diet. Non-essential amino acids can be produced by the body within the liver. The correct ratios of essential and non-essential amino acids must be present in sufficient quantities before any muscle can be produced.
