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-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-Histidine is an amino acid which is present in proteins. It is furthermore one of only twenty amino acids located there and is considered essential for human infants. Older children and adults are able to synthesize histidine, which thereafter is deemed non-essential. Histidine is viewed as a precursor for the biosynthesis of histamine, but also of carnosine. The enzyme necessary for the synthesis of histidine into histamine is called histidine decarboxylase. Histidine transmiase is able to transfer L-Histidine into (imidazol-5-yl)pyruvate and L-glutamate. L-Histidine is deemed necessary also for the utilization and regulation of other essential trace minerals by the human body, these minerals are manganese, iron, zinc, copper and molybdenum. With help of histidine kinase, protein L-Histidine and adenosine triphosphate can be converted into adenosine diphosphate and protein N-phospho-L-histidine.

L-Isoleucine is one of the amino acids besides the other two, L-Valine and L-Leucine. These are found in all the forms of life as proteins. They are as well obtainable in the diet through vegetable and animal sources. L-Isoleucine is good to regulated blood sugar as well the energy levels. It is also important in the synthesis of hemoglobulin and thereby increases endurance. L-Isolecuine gets metabolized in the tissues of the muscles and the opulent L-Isolecuine sources are almonds, cashews and soy protein. Hence, this is prominent among athletes and is taken in combination with the other two amino acids, L-Leucine and L-Valine. L-Isoleucine is required for the formation of hemoglobin and also regulates as well as stabilizes the energy levels. The other food sources of L-Isoleucine are eggs, meat, fish, rye, chickpeas, chicken, liver and lentils. People suffering from physical and mental disorders are usually deficient in L-Isoleucine. These amino acids are required for the synthesis of enzymes, structural protein and for hormones.

L-Leucine is an essential amino acid that works together with isoleucine and valine, forming the three branched chain amino acids (BCAA). Leucine is easily converted by to body to glucose, helping to regulate and maintain the blood sugar level. Leucine promotes muscle recovery, muscle repair and provides the body with energy. It also helps in burning fat that are least responsive to exercise and dieting. Leucine helps in toning the body and the muscles. Leucine prevents muscle loss by breaking down and converting to glucose, this prevents the body from breaking down muscle tissues to create energy, particularly during intense workouts and heavy weight lifting.

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-Methionine- One of the most significant amino acids there is for the breaking down of fats. It is water-soluble and is known for deactivating free radicals. Recognized as being a leading antioxidant.

L-Phenylalanine is a vital amino acid. It acts as a building block for various proteins produced in the body. It is found in most foods that contain protein, like poultry, beef, pork, milk, fish, yogurt, cheese, eggs, soy products, and certain nuts and seeds. It can assist in decreasing chronic pain linked with different health conditions by inducing nerve pathways in the brain which control pain. It can also help improve rigidity and is beneficial in conditions like walking disabilities, depression associated with Parkinson’s disease, and speech difficulties. Combination of L-Phenylalanine with ultraviolet radiation for people having vitiligo, a condition that is characterized by irregular depigmentation or white patches of skin, can lead to some darkening or repigmentation of whitened areas, especially on the face.

L-Threonine optimizes the utilization of animals that you consume in order to deposit protein to the muscles and aides in weight gain.

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.

Phosphate (Phosphorus) is perhaps one of the most important mineral, which in form of phosphate as an intercellular anion serves a multitude of functions. Not only are phosphates essential for the utilization of most vitamins belonging to the B complex, but they are vital for energy storage and the overall metabolism. But that is not all, phosphate is essential for healthy bones and teeth, calcium with phosphorus are required for them and soft tissues as well. But also body fluids require phosphates for excretion of hydrogen ions through the kidneys. Somewhere around one per cent of the body weight should be phosphorus in some form, therefore it is vital to supply your body with sufficient phosphates through milk, cheese, nuts, peanut butter, peas and other sources, including supplements.
