Choline was discovered in 1864 by Andreas Strecker, Choline is a water soluble organic compound. This nutrient is found in the neurotransmitter acetylcholine and lipids which make up cell membranes. Choline is a member of the Vitamin B Complex group and it is generally required for physiological purposes like structuring of cell membranes, as a precursor molecule for neurotransmitter acetylcholine and to protect the livers from accumulation of fat. Besides the infant or fetus brain development, choline can also prevent memory loss caused due to aging. Your homocysteine levels related to cardiovascular diseases and cholesterol can be lowered by it. The recommended intake of choline which is found in peanut butter, beef liver, cauliflower and almonds is 550 mg for men and 425 mg for women.

L-Carnitine - Carnitine is a quat, quaternary ammonium cation, which is derived through biosynthesis of amino acids lysine and methionine. During the breakdown of stored fat in the lipids for purposes of generating additional metabolic energy, carnitine is needed to transport the fatty acids from the intracellular fluid to the mitochondria. The biologically active form of this stereoisomer is named l-carnitine. It is believed that l-carnitine has strong antioxidant effects and that it can strengthen the bone mass during the aging process. It is furthermore believed that l-carnitine promotes the glucose uptake and that it improves the male fertility in clinical trials. Concentrations of carnitine are found in highest levels in red meat and dairy products, but also in some seeds and pulses, as well as cereals and some fruits.

L-Tyrosine is a common amino acid and a para-isomer of tyrosine. It is deemed organic because of the carbon atom present and it is nonessential to survival, but works as a building block of protein. It is also viewed as a precursor of dopamine, which has several effects, like offsetting fatigue, mental and physical, as well as increasing the impression of well being. When the amino acid phenylalanine is broken down, L-Tyrosine can be won completely naturally.

In body building circles this supplement is popular to offset fatigue after a hard training or competition, but also to raise mental alertness while working out.

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 widely used for its effective use to treat acne. It is also used to relieve pain caused by rheumatoid arthritis and to relieve morning stiffness.

Since it is very easily digestible and provides a balance of necessary nutrients, it has become a potential source of probiotic, whole food. For instance, the blue colored pigments called phycocyanin are known to combat cancer. For these reasons, Spirulina is also considered to be a beneficial biochemical and medical resource. Through ages, the alga has been widely used for its nutritional properties by the indigenous people of North Africa and Mexico. But now, Spirulina is used in dietary supplements also.
