Caffeine, is a naturally produced medicine from the seeds and leaves of many plants. It is also produced unnaturally to add to certain foods. Caffeine is termed as a medicine because it arouses the central nervous system, causing enhanced alertness. Caffeine gives most people a short-term energy boost and bump up mood. Caffeine is present in tea, many soft drinks, coffee, chocolate, and pain relievers and other over-the-counter medicines. Caffeine tastes very bitter in its natural form. However, most caffeinated drinks undergo processing to cover-up the bitter taste. You may feel caffeine’s effects for up to 6 hours though it is not stored in the body.

L-Arginine AKG is a salt of amino acid arginine and alpha-ketoglutaric acid, and is widely used as a body building supplement. Its components assist in the metabolism of nitric oxides. Arginine and alpha-ketoglutarate are forerunners of polyamines and nitric oxide, which take part in a number of metabolic functions. Its supplements enhance growth hormone and insulin secretion with anabolic effects in postoperative patients. Their intermediary metabolites, glutamine and proline, can also help promote recovery from trauma. In animal studies, it increased the levels of glutamine and arginine in skeletal muscles and stimulated the immune system function as compared to animals which did not receive it. It can also improve host-defense mechanisms, especially during injury and acute stress.

L-Glutamine- Found in plasma and muscles of the human body, L-Glutamine is an essential amino acid. In the skeletal muscle cells, more than 60% of free floating amino acid is made of L-Glutamine. It acts as the primary donor of nitrogen and moves in the body wherever required. This amino acid has been considered useful in reducing physical stress. During surgery or heavy exercise regime the human body needs it for maintaining the level of glutamine in muscles and blood. It is also essential for maintenance of immune system and prevention of intestinal stress. Glutamine supplements can help in restoring L-Glutamine levels during stress. L-Glutamine supplements are relatively less expensive and help in minimizing the breakdown of muscles. It also improves the metabolism of protein in the human body and ensures a positive balance of nitrogen.

L-Lysine is an essential amino acid obtainable from daily food sources we consume. It has many medicinal properties which benefit us in our daily lives. While it is mainly used in the treatment of herpes, it also helps us become stronger by building our muscle tissues. It helps us to recover form injuries and surgeries besides absorbing calcium for building healthy bones. It also regulates the production of antibodies, enzymes and hormones which are required for healthy immunity level. L-lysine when consumed in high doses can lead to serious conditions. Although L-lysine is important for good health, we never really realize we are consuming it. Deficiency of L-lysine causes lethargy, amnesia, enzyme disorders, reproductive problems and hair loss. Generally, L-lysine is present in all vegetarian and non-vegetarian foods. Fish and cereals have higher amount of L-lysine in them.

L-Ornithine is produced when the enzyme arginase reacts on L-arginine, whereby urea is being created. Consequentially, ornithine seems to be a vital part of the urea cycle, the disposal of ammonia and the removal of excess nitrogen. Although ornithine is not coded for by the DNA, which means that it is not a part of the protein synthesis processes. Despite this fact, the urea cycle plays a big part in arginine biosynthesis, which means that as an intermediate in a metabolic process, ornithine still retains vital importance. L-Ornithine is gaining on popularity as a nutritional supplement, in particular with the body building circles, where it is propagated as a muscle building and fat loss agent. It is furthermore stated that L-Ornithine may be initiating the release of growth hormones in the body.

L-Ornithine Alpha-Ketoglutarate is a combination of two amino acids, namely: ornithine and glutamine. They are considered “conditionally essential” because the body can produce these two amino acids by it self. L-Ornithine Alpha-Ketoglutarate has both anabolic and anti-catabolic effects. L-Ornithine Alpha-Ketoglutarate’s anabolic property stimulates the body to build muscles and other tissues; the anti-catabolic property, on the other hand, blocks the effects of hormones that cause the muscles and other tissues in the body to break down. L-Ornithine Alpha-Ketoglutarate increases the energy level, endurance and muscle mass as it slows down the fatigue and the build up of unwanted fats. It also speeds up the recovery and healing of muscle.

L-Taurine , a semi-essential amino acid found in the heart muscle, central nervous system, white blood cells, and skeletal muscle, may not be as popular as other types of aminos such as glutamine, but is extremely crucial. It is also vital for metabolism. While taurine is made in adults’ bodies, newborns cannot make it. If the body fails to produce it in sufficient quantities, it is possible to correct this deficiency by using L-Taurine supplements. You are likely to get enough taurine if you are a meat eater since it is found in abundance in eggs, meats, fish proteins, and dairy products. Generally, vegetarians and women of all ages are at a greater risk of developing a L-Taurine deficiency. It is possible to treat depression, low sperm count, low sperm motility, high blood pressure, and cirrhosis using this supplement.

NADH or nicotinamide adenine dinucleotide hydrogen is a double nucleotide and is the reduced form of NAD. It acts as an electron carrier in the body. Chemically it is composed of two nucleotides adenine and nicotinamide joined through their phosphate groups.

Vitamin B3, commonly called Niacin, exists in two main forms, niacin and niacinamide. The niacin form produces a flushing and itching of the skin when taken at higher dosages and this feeling is only temporary.

Yohimbe is a tree that grows in different parts of Western Africa. Active compounds called alkolids are present in its bark with Yohimbine being the principal alkaloid. Yohimbe bark extracts are available in health food outlets. You can also buy it online. These extracts are promoted as a product that increases sex drive and for the treatment of erectile dysfunction. However, there is proof of their effectiveness. Most studies are concerned with the drug Yohimbine and not herbal extract Yohimbe. The side effects of Yohimbe include anxiety and dangerous increase in blood pressure.
