Beta-Hydroxy-Beta-Methylbutyrate or Calcium HMB is a metabolite of the essential amino acid leucine. It is naturally produced in human body and small quantities can also be found in grapefruit, alfalfa, and catfish. Calcium HMB is used as a supplement because research has shown it to Increase sarcolemmal integrity via conversion to HMG-CoA and to enhance protein synthesis. It also helps in depression of protein degradation through inhibition of the ubiquitin pathway. Calcium HMB is proved to help muscle formulation so it is given to patients with HIV or AIDS and trauma victims with severe injuries. It is also used in treatment of cancer.

Creatine Monohydrate- I- methionnine, I- glycine and I- arginine are responsible for the composition of creatine in the body which acts as a metabolite. Minimum of 2 grams of creatine is metabolized even in an inactive person. Hence, those who are into heavy duty workouts and weight lifting have higher amounts of metabolism of creatine. Some types of fishes and red meat would be an ideal source of creatine monohydrate. However, the quantity derived by these may not be sufficient hence it is advisable to take creatine in the form of powder. Creatine is beneficial to pump your work out sessions. However, it has some side effects. One common side effect of creatine monohydrate is gastro entreaties, but it might not affect everyone.

L-Arginine - Several functions in our body are carried out by L-Arginine that is actually an amino acid. Its major advantage is to help the body get free of the waste product named ammonia. It also helps in the development of compounds such as L-proline, L-glutamate and creatine in the body. If required, it can also be converted into glycogen or glucose. The blood vessels in our body our relaxed by the compound named nitric oxide which is produced by the help of L-arginine. Another great advantage of L-arginine is the formation of protein in our body. Many other uses of L-arginine is found in the treatment of erectile dysfunction, healing of wounds, reducing high blood pressure and many more.

L-Citrulline is an amino acid that helps in improving the flow of blood by changing into L-arginine and then nitric oxide. Nitric oxide helps to improve the mental and physical well-being of an individual by increasing blood circulation. Due to this action of the amino acid on the circulation of blood in the body, blood pressure problems are kept well under control. l-citrulline assists in the stimulation of growth enhancing hormones, helps in promoting the smooth functioning of the Urea Cycle, responsible for building up a part of the energy reserve of the body and in fortifying the immune system. A deficiency in this particular amino acid leads to fatigue- both mentally and physically as well as being one of the causes of sexual dysfunction.

L-Glycine- Glycine is an organic compound and one of the 20 amino acids deemed as building blocks for proteins. This proteinogenic amino acid is not only the smallest but also the only amino acid of the group that is not chiral, which means there is no enantiomer of glycine. With the prominent exception of collagen, which thirty five percent are glycine, most proteins contain only small amounts of it. As a solid, glycine is sweet tasting, crystalline and has no color. Despite being non-essential, because it can be biosynthesized from the amino acid serine, glycine has several important physiological functions, besides being a precursor to proteins. It is a biosynthetic intermediate of purines and the D-Aminolevulinic acid and it is an inhibitory neurotransmitter found in the central nervous system.

L-Ornithine is an amino acid that is commonly used in various nutritional supplements. It aids the metabolism and promotes the excretion of growth hormones. It helps develop lean muscles and burns body fat. It also boosts the immune system function and protects the body from acquiring illness caused by infections. It also aids in detoxifying the body from toxins that may cause serious diseases. L-Ornithine promotes the development of muscles and prevents catabolic activity. It benefits the elderly because it prevents muscle degeneration. It helps burn fats for energy supply and promotes formation of muscles. It also helps in regulating blood sugar and blood cholesterol level.
