REXIVA® is a range of highly purified amino acids suitable for all nutritional applications – from infant and sports nutrition to supplements and flavors.
Simply put, amino acids are the building blocks of life. These constituents of proteins are involved in most biochemical processes within the human body. As a result, they play an integral role in metabolism and overall health.
The amino acids found in proteins are called protein genic amino acids. These are all L-amino acids and can be divided into two categories: essential and non-essential. Essential amino acids cannot be synthesized by the body and therefore need to be obtained from diet, whereas non-essential amino acids can be synthesized within the body.
Amino acids have a wide range of important functions. They synthesize proteins such as enzymes, immunoproteins, transport proteins, peptide hormones, structural proteins (e.g., skeletal muscle and collagen. Additionally, through absorption in the gastrointestinal tract, they induce catabolism for energy production.
One amino acid that is converted within the body into serotonin is L-Tryptophan, which is used as sleeping aid. Branched chain amino acids (BCAAs), on the other hand, must be replaced by diet. They are essential for building skeletal muscle and are metabolized during exercise. L-Lysine, like BCAAs, cannot by synthesized by the body. This is a building block for proteins in the body, required for collagen synthesis and possibly integral to bone health.
