Caffeine is a methylated xenthine discovered in 1819 by Friedrich Ferdinand Runge, a German chemist. Sources of Caffeine include beans, fruit and leaves of some plants. Caffeine available for human consumption is most commonly extracted from the coffee plant cherries and tea bush leaves, as well as foods and drinks that contain products derived from the kola nut. Caffeine can temporarily reduce the sensation of being tired; however, this does not mean that it eliminates the need for sleep. Generally, twenty five to fifty milligrams of caffeine is enough for most consumers to report an increase in alertness and arousal. Caffeine should be not be consumed by those with fecal incontinence as it relaxes the internal anal sphincter muscles.

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- Glutamine is an amino acid which is responsible for a multitude of biochemical functions in humans. L-Glutamine is generally found in dietary sources such as chicken, beef, eggs, milk and dairy products, fish, spinach, wheat, parsley, cabbages, beans and beets. Glutamine is apparently the most common amino acid occurring naturally, furthermore this non essential amino acid is one of just a few, which are able to directly cross the blood brain barrier. In the human body, L-Glutamine is found in the skeletal muscles, but also in the blood. Besides the vital biological functions, such as fuel for brain, blocking cortisol induced protein catabolism, immune function assistance, protein synthesis and in DNA synthesis, L-Glutamine is used as a supplement for ailing and injured, improving recovery, but also as muscle growth agent in body building and athletic circles.

L-Lysine- Lysine is an essential alpha amino acid that needs to be ingested and cannot be synthesized by the human body. Sources of L-Lysine include meat, particularly red meat, lamb, poultry and pork, but also cheeses, like parmesan, some fish like cod and sardines and eggs. Several plants are rich in L-Lysine, soybean, lentil, spinach and buckwheat, but also buffalo gourd, watercress, locust bean and many other bean variants, including the common bean. L-Lysine is deemed vital for the overall production of protein, as a structural building block. It seems that L-Lysine also plays a prominent part in the absorption of calcium. Further properties include playing a role in the production of enzymes, hormones and antibodies, but also in the recovery from sports injuries and surgeries.

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 , which contains cysteine and methoinine is an essential amino acid. It acts as a diuretic by maintaining the level of magnesium and potassium in our cells while purging sodium. It improves the functioning of kidney and gets rid of fluid accumulation and swelling and thus keeps our body away from toxicity. It maintains a good balance of calcium in our body and strenghtens the heart muscles too. L-Taurine is also used in the treatment of progressive eye conditions, hypertension, memory loss, cystic fibrosis and in atherosclerosis. It is often mixed in energy drinks because while working out the level of L-taurine drops in the skeletan muscle, L-taurine supplements lowers the level of exhaustion and improves endurance. Besides being found in meat and egg yolks it is abundantly found in shellfish.

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 an alkaloid and the active ingredient of a medicinal herb also known as Pausinystalia yohimbe, formerly named Corynanthe yohimbe. It is noted as a stimulant drug and also as an aphrodisiac. While the medicinal community has conducted numerous studies of yohimbe in conjunction with sexual dysfunctions, in veterinary medicine, yohimbine is employed as the antidode to anesthesia stemming from the drug xylazine in large and small animals. In recent times, yohimbine has been found to instigate fat loss in athletes when taken orally. There are also some formulations available, for a significant price, where yohimbine can be directly applied transdermally to adipose tissue, leading to a local reduction. This application is still in experimentation and should not be used without professional assistance.
