Vitamin B Complex is a term that describes dietary supplements which contain all 8 types of Vitamin B. The eight distinct forms of Vitamin B are:
- B1 (Thiamine)
- B2 (Riboflavin)
- B3 (Niacin)
- B5 (Pantothenic Acid)
- B6 (Pyridoxine)
- B7 (Biotin)
- B9 (Folic Acid)
- B12 (Cobalamin)
Each form of Vitamin B has a different function in the body but they are all important for cellular metabolism. B Vitamins are popular nutritional supplements and are purported to help increase metabolism and boost energy levels. B Vitamins are rarely used as a direct treatment for acne, but they are frequently incorporated into comprehensive acne treatment regimens as part of the nutritional plan.
B vitamins primarily function as coenzymes. Coenzymes are molecules that are essential for the structure and function of certain enzymes and other proteins. B vitamins occur naturally in many foods and processed foods are often fortified with additional B Vitamins. B Vitamin deficiencies are rare in most regions of the world. People who have B Vitamin deficiencies can experience a range of health problems, including skin problems. In particular, deficiencies in Vitamins B2, B5 and B6 are known to cause acne or acne-like symptoms.
Some people have reported that their acne symptoms improved after starting daily Vitamin B complex supplements. Vitamin B supplements are known to significantly improve skin health in people who have Vitamin B deficiencies. However, there has been little scientific research into whether Vitamin B supplements are effective acne treatments in people that do not have Vitamin B deficiencies. There are also conflicting reports on how Vitamin B supplements affect the bacteria (eg. Propionibacterium acnes) that contribute to acne symptoms. Currently, there is no robust scientific evidence to indicate Vitamin B supplementation can significantly reduce the frequency or severity of acne symptoms for most people.
All forms of Vitamin B are water soluble and excess Vitamin B is readily eliminated by the body in urine. Therefore to get a benefit from Vitamin B it should be taken daily. When consumed at the recommended dosages, Vitamin B complex supplements are generally quite safe. However, very high doses of B Vitamins can cause side effects. Vitamin B toxicities are more likely to occur in individuals who are having Vitamin B cocktails injected intravenously. Interestingly, there have been reports that very high doses of Vitamin B12 can trigger acne symptoms in some individuals.
Overall, Vitamin B supplements are healthy additions to almost any dietary program, when used at recommended dosages. Although Vitamin B supplementation is unlikely to dramatically improve acne symptoms for most individuals, it may be helpful for some people. If you would like to experiment with high dose Vitamin B therapy, it is best to avoid Vitamin B Complex (and Vitamin B12 specifically) and focus on Vitamins B2 (Riboflavin), B5 (Pantothenic Acid) and B6 (Pyridoxine).
