Niacin is a vitamin that wards against pellagra, a disease characterized by a vitamin B3 deficiency. Niacin is made from pyridine and is often called vitamin B3 or nicotinamide, because they all three have similar formulas. Niacin and nicotinamide are comparable in make up, but only niacin works to lower cholesterol levels. The restoration of DNA is also known to be a positive side effect of taking niacin. A fairly large number of individuals, particularly those in third world countries or those suffering from alcoholism, have been shown to be lacking in niacin. Niacin is often taken as a supplement by those with high cholesterol levels, as it has been proven to lower “bad” cholesterol and raise “good” cholesterol.

Quercetin is a flavanoid derived from plants and is widely used as a nutritional supplement. There are many studies which are being conducted to exactly determine the benefits of Quercetin. It is said to have antioxidant and anti-inflammatory properties and hence is being tested to help curb and cure terminal diseases like cancer. The high intake of fruits and vegetables is good for cancer treatments. Many researchers believe that these qualities of Quercetin are what allow it to be used for treating cancer as well. Quercetin is classified into the IARC group 3; which categorizes food and drugs as that which are not carcinogenic.

Riboflavin, also called Vitamin B2, is naturally manufactured by the body. Riboflavin is needed for the proper use of oxygen and amino acids, carbohydrates and fatty acids. Riboflavin is also utilized by Vitamin B6 in the body and is used to manufacture niacin. Riboflavin is especially needed when eating large amounts of protein.

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

Vitamin A is needed by the retina of the eye in the form of a specific metabolite(the light-absorbing molecule retinal). This molecule is absolutely necessary for both scotopic and color vision. It also palys an important role in the health or our skin, bone metabolism, immune function. It is also commercially produced and administered as esters such as retinyl acetate commonly called Vitamin A acetate. Its defeciency can cause blindness. Other problems include impaired immunity, hypokeratosis (white lumps at hair follicles), keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

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 B6 is one of the most important vitamins that play an essential role in the development and keeping the immune system healthy. Vitamin B6 is water soluble that contains pyridoxal, pyridoxine, and pyridoxamine. It is needed by the body in various functions such as red blood cell metabolism and conversion of the amino acid tryptophan to the vitamin niacin. It is also important in ensuring the efficient function of the nervous and immune systems. It helps manufacture proteins and neurotransmitters, haemoglobin, and prostaglandins. It also helps balance the hormones. Vitamin B6 is known to help give relief to women suffering from menopausal symptoms, and premenstrual syndromes. It also helps reduce the incidence of breast cancer.

Vitamin C, also known as Ascorbic (a-SKOR-bik) acid, is needed for many functions in the body, including helping the body use carbohydrates, protein, and fats. Vitamin C is found in most citrus fruits and green vegetables and is a strong antioxidant.

Vitamin E is the name for a group of tocopherols and tocotrienols that are soluble in fat and display antioxidant properties. The most important vitamin out of this group is alpha tocopherol, which professes the highest bioavailability, and therefore, was the most studied Vitamin E. Found in such foods as nuts, seeds, milk, wheat germ and most vegetable oils, this Vitamin is said to be perhaps the most important antioxidant in human nourishment, although this trait is not deemed the imperative reason why Vitamin E is required to be in every diet. Most clinical studies which were supposed to crown Vitamin E as the prevention from prostate cancer or cardiovascular wonder supplement have been either inconclusive or were discontinued due to poor results. Vitamin E deficiency results in neurological and neuromuscular problems, but also in failure to absorb fat.
