L-Isoleucine is an essential alpha-amino acid that is considered both, a ketogenic and a glucogenic amino acid. Since that L-Isoleucine is an essential amino acid, it cannot be synthesized by the body, therefore it needs to be ingested. The primary source of L-Isoleucine is as a component of proteins. It has become a prominent component of nutritional supplements, mostly with the body building and similar athletic communities, where it is believed that L-Isoleucine has the capability to increase endurance, but also to repair muscle tissue. It has been observed that L-Isoleucine ingestion allows power athletes to recover easier from very tough trainings and exhausting activities. This branched chain amino acid is one of the three main BCAA in the body, the other ones being valine and leucine.

L-Leucine with the food additive E number code E641 is classified as a flavor enhancer. Leucine is actually an essential alpha-amino acid and a vital part of so called “buffer” proteins, such as ferritin and astacin. You can find leucine in foods such as whole wheat bread products, nuts and brown rice. As a supplement, researchers have found that leucine slows the degradation of muscles and muscle tissues through an inflated synthesis of muscle proteins. In the human body, leucine can be found in the liver, but most prominently in the muscle and adipose tissues, where it is utilized in production of sterols. In body building circles L-Leucine as a dietary supplement is very popular for all these properties, but also for the preservation of muscle glycogen, nitrogen balance maintenance and more.

L-Valine, an essential amino acid, promotes the smooth functioning of the body. It is derived from animal and vegetable proteins like seafood, poultry, meat, cottage cheese, sesame seeds, dry whole lentils and roasted peanuts. It regulates the immune system, assists protein synthesis and glucose metabolism. It also promotes growth of muscles and repair of tissues that get damaged due to stress, disease, surgery or injury. It maintains the body’s nitrogen level and energizes the muscles. L-Valine helps detoxify the body against ammonia and prevents muscle wasting in diabetics. It assists in correcting drug addiction related amino acid deficiencies, gallbladder and liver diseases and is linked with treating neurological conditions and brain damage due to alcohol intake. One should consult a physician before consuming the supplement.

Taurine is basically an amino acid that is not formed by the body. It is found freely in the bloodstream and in tissues. It is also found in abundance in the skeletal system, the heart and the nervous system. During times of extreme physical activity, the amounts of taurine in the body are depleted. Taurine has a tendency to act as a metabolic transmitter and can also be used as a detoxifying agent. It has been added to a number of products for infants as well. The popular energy drink ‘Red Bull’ is well known for its taurine content. Taurine is also recommended for use by people who suffer from manic depression. Taurine is tested and has proven to be an extremely safe dietary supplement.
