Biotin, also called Vitamin H or Vitamin B7. Biotin is a water-soluble B-Complex Vitamin that is needed for the metabolism of fats, carbohydrates and proteins.

Caffeine- The bitter, white crystalline xanthine alkaloid caffeine is found in tea, coffee, soft drinks, chocolates, pain relievers, and a variety of over the counter medications. It is a psychoactive stimulant drug that causes increased alertness by stimulating the central nervous system. For the same reason, many people feel more energetic after consuming it. It even elevates the mood but these effects do not last for long. The effects of caffeine usually last for about five to six hours, though caffeine sensitivity varies from person to person. It has been found that people who consume lot of caffeine on a daily basis soon develop less sensitivity and may need to increase their intake to enjoy the same effect. Being a diuretic, a person consuming caffeine may have to urinate more often.

Chromium Picolinate is a combination of chromium and picolinate acid. Combined with exercise, it is commonly used to lose weight through reducing appetite, increasing metabolism rate and melting fats. This, however, has not been proved clinically. It is also believed to increase energy, life span, prevent acne and improve a person’s mood. Being considered a natural alternative to steroids, it is recommended to athletes. Chromium is found in fish, poultry, whole-grains, cheese and meat. It helps in the proper working of cells by improving the efficiency of insulin. Picolinate acid helps in the proper absorption of chromium. A combination of chromium picolinate and other supplements may be risky, hence professional advice should be sought before using it. Pregnant or nursing women should also be careful.

Folic Acid, also known as Vitamin B9 or Folacin is a water-soluble vitamin. It is very essential to several bodily functions including nucleotide synthesis to the remethylation of homocysteine. Vitamin B9 is also very important during the periods of rapid cell division and growth and thus it is essential that pregnant women have an adequate intake of folic acid. This is also because Vitamin B9 helps protect against a number of congenital malformations like spina bifida etc. Vitamin B9 should be a part of the diet of both adults and children as it is required to produce healthy red blood cells as well as prevent anemia. It is also necessary for fertility in both men and women. It isn’t difficult ingesting vitamin B9 since it is present in green leafy vegetables like spinach, lettuce, beans, peas, sunflower seeds, liver, baker’s yeast etc.

Hoodia Gordonii grows in Namibia and South Africa naturally. It is a leafless spiny plant useful for medicinal purposes. These flowers are pollinated by flies mainly as they smell identical to rotten meat. Hoodia is known long by indigenous population and is infrequently used for treating small infections and indigestion. This is used to suppress appetite during long hunting trips such as Kalahari Desert that interests more tourists. Hoodia Gordonii was prominent for it appetite suppressing effect and hence was collaborated with Pfizer, a pharmaceutical company to deal with obesity. However, it was stopped as it is stated to have indications of effects on liver. Hoodia Gordonii is wild harvested by individuals as well as by few companies that are granted license. However, there is no evidence of Hoodia working in humans as appetite suppressant. Due to the lack of clarity and fear of breaking down of liver, it is not recommended for obesity.

L-Arginine is an amino acid that performs several functions in the human body. L-Arginine not only helps in getting rid of the ammonia but also aids the formation of nitric oxide, a compound responsible for relaxation of blood vessels. This amino acid is also involved in the formation of protein in human body. Besides stimulating the release of prolactin and growth hormones, L-Arginine can help in the treatment of heart diseases as it increases blood flow and improves the function of the blood vessels. It is effective for treating erectile dysfunction and heals wounds effectively. L-Arginine is produced in the liver as well as the kidney. Food items which include this acid are animal proteins like meat, fish, poultry and plants. L-Arginine supplements become essential when the supply of arginine depletes because of infections and severe burns.

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-Tyrosine is a non-essential amino acid, which is used by the cells in order to synthesize the proteins and appears to help stabilize ones mood during periods of high stress levels.

Niacin is an essential B vitamin, in cellular energy used for the promotion of healthy cardiovascular function, nervous system function, and immune function. Niacin nutritionally manages cholesterol levels already within the normal range. Also known as vitamin B3, niacin is one of a complex of B vitamins that are essential for good health. Niacin is so-called nicotinic acid, known also as nicotinamide. It helps regulate blood sugar and also works at cellular level protecting the skin and enhances the digestive system. And being an originator of the amino acid tryptophan, it can be made by tryptophan in the body. It’s also a coenzyme playing an important role in body metabolism. Supplements of vitamin B3 are also known to reduce levels of bad cholesterol and increase good cholesterol in the blood.

Pantothenic Acid is thought to reduce lactic acid accumulation in athletes, may improve oxygen utilization efficiency, and is believed to improve the body's ability to heal and possibly help in reducing acne

Vitamin B1, also called Thiamin, is needed to help the body utilize energy from proteins, fats and carbohydrates. Vitamin B1 is commonly found in breads and cereals. Vitamin B1 is water-soluble and is concentrated in muscle tissue as it passes thru the body.

Vitamin B12, also known as cobalamin, which is naturally found in foods such as fish, milk and milk products, eggs, meat and poultry. Vitamin B12 is important for good health, necessary for the proper digestion and absorption of foods and for normal metabolism of carbohydrates, and fat. It helps maintain healthy nerve cells and red blood cells and is needed to make DNA. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Unlike other water-soluble nutrients, vitamin B12 is stored in the liver, kidney, and other body tissues. It can take several years before signs of the deficiency appear due to poor dietary intake. Vitamin B12 functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups to other molecules, including cell membrane components and neurotransmitters. As a methyl donor vitamin B12 is involved in homocysteine metabolism and plays a critical role in proper energy metabolism, immune function, and nerve function. Therefore, vitamin B12 is clearly an added benefit for anyone wanting to lose weight, as without it, metabolism is not at its peak potential.

Vitamin B2 is a water-soluble vitamin with no known toxic effects. Riboflavin (Vitamin B2) is necessary in the oxidative process of metabolism. It is also sometimes used to correct certain enzyme deficiencies and improve mental processes.

Vitamin B6 is important to a healthy human diet and is equally important in various metabolic and synthesis functions as well as gene expression.
