1. What is Vitamin B7?

You may recognize vitamin B7 by its common name biotin. This is a water-soluble B vitamin found naturally in some foods and also in supplements. Biotin plays an important role in supporting enzymes that break down fats, carbohydrates and proteins in food. It also helps regulate the signals sent by cells and the activity of genes. Recommended Dosage (RDA) does not exist for biotin because there is not enough evidence to recommend a daily intake needed for most healthy people. Instead, there is an AI (Adequate Intake), which is assumed to ensure adequate nutrition. AI of biotin for men and women 19 years and older and for pregnant women is 30 micrograms per day. Breastfeeding women need 35 micrograms per day. The safe upper limit of intake (UL) is the maximum daily intake that is unlikely to cause harmful side effects in the general population. There is no UL for biotin due to lack of reports showing negative effects from very high intakes.

Researchers have also noted that some hair loss conditions can go away on their own without treatment, so it's impossible to say that biotin supplements specifically help hair regrow.

Since biotin is an important factor in glucose synthesis, it may help maintain proper blood glucose levels in patients with type 2 diabetes. Despite the inconclusive evidence, vitamin B7 supplements are still very popular. Biotin is often added to multivitamins and supplements for hair, nails, and skin. While vitamin B7 can be found in some cosmetics, it's important to remember that it can't actually be absorbed through the skin, hair, or nails. The FDA recommends that people inform their doctor at each visit about all supplements and dosages they are taking.
