Vitamin B7 is a vitamin that converts the food you eat into energy in your body. It is also responsible for gene regulation and cell signalling. The adequate intake (AI) of Vitamin B7 to ensure no deficiency for adults is 30 mcg per day.
You should only take a Vitamin B7 supplement when you have a Vitamin B7 deficiency, which is quite rare, or when you are unable to take sufficient Vitamin B7 from your diet. Symptoms of Vitamin B7 deficiency include thinning of hair and skin, brittle nails and red rashes.
Vitamin B7 is usually taken by mouth in tablets. The usual adult dose is one tablet daily (30-3000 mcg per day). For specific dosages, refer to the product label.
Vitamin B7 is water-soluble and accumulation in the body is unlikely. It has no potential side effects. If you experience side effects, tell your doctor or pharmacist immediately.
