Vitamin B complex

There are eight vitamins which, together, make up the vitamin B complex. They are all water-soluble, as opposed to fat-soluble, which some other vitamins are. Basic information on the items which make up this complex is mentioned on this page.

Vitamin B1 (thiamine)

Brewer's yeast is one of the highest sources of this. A deficiency in it leads to a condition known as beriberi. This one is the main topic of this website. You can return to the home page to read further on vitamin B1.

Vitamin B2 (riboflavin)

A deficiency of this is the cause of ariboflavinosis. Milk, almonds and wheat bran are a few of natural sources of riboflavin. It has a yellowish color and is also used for food coloring.

Vitamin B3 (niacin)

An excessive intake of niacin can sometimes lead to symptoms, including flushing of the skin. On the other hand, pellagra is a disease that is usually caused by insufficient ingestion of niacin. If a deficiency is minor, it may reduce the patient's metabolism.

Vitamin B5 (pantothenic acid)

This is used in the synthesis of what is known as coenzyme A. It can be found, in tiny amounts, in most foods. A couple of examples of natural sources that are higher in it are eggs and yogurt. Cases of insufficient levels of this are rare.

Vitamin B6 (pyridoxine, etc.)

This was discovered in 1934. Being involved in the metabolism of amino acids is one of its functions. The amount that is recommended to be ingested on daily basis varies by age, gender, and certain situations. For instance, the Recommended Dietary Allowance (RDA) is 1.3mg for a 25-year-old male, and is 1.9mg for a pregnant female of the same age.


Vitamin B7 (biotin)

One of the things that is accomplished by biotin is its involvement in gluconeogenesis. It can be located in various foods, altough there are not many that have an especially high amount of it. Peanuts and Swiss chard are a couple of foods with a greater content of it. A low level of biotin in a patient is somewhat rare.

Vitamin B9 (folic acid)

It is thought that a particularly high level of folic acid may be able to mask a deficiency of vitamin B12, although there is little evidence of confirmed occurrence of this. Having a low level of folic acid, though, can cause anemia, amongst other issues.

Vitamin B12 (cyanocobalamin, etc.)

This is sometimes referred to as cobalamin, with cyanocobalamin being only one particular type, which does not appear naturally but is rather a synthetic form, and is used in many supplements. As for vitamin B12 in general, a deficiency in can possibly lead to serious damage to the person's nervous system and brain, and this may be irreversible.
