1.Vitamin H

Biotin, also known as vitamin H or coenzyme R, is a water-soluble B-vitamin (vitamin B7). Vitamin H is a colorless, water-soluble member of the B-complex group of vitamins. Although Vitamin H was discovered already in 1901 as a special growth factor for yeast, it took nearly forty years of research to establish biotin as a vitamin. Due to its beneficial effects for hair, skin and nails, Vitamin H is also known as the “beauty vitamin”. Biotin can only be synthesised by bacteria, moulds, yeasts, algae, and by certain plant species.

2.Dietary sources

Vitamin H is widely distributed in most foods but at very low levels compared to other water-soluble vitamins. It is found in free and protein-bound forms in foods. Its richest sources are yeast, liver and kidney. Egg yolk, soybeans, nuts and cereals are also good sources. 100 g of liver contains approximately 100 µg biotin, whereas most other meats, vegetables and fruits only contain approximately 1 µg biotin /100 g. In animal experiments, biotin bioavailability has been shown to vary considerably (5%-62%), and in cereals it appears to be lower.

3.Recommended Dietary Allowance

In 1998 the Food and Nutrition Board of the Institute of Medicine felt the existing scientific evidence was insufficient to calculate an EAR, and thus an RDA, for Vitamin H. Instead an Adequate Intake level (AI) has been defined. The AI for Vitamin H assumes that current average intakes of Vitamin H (35 µg to 60 µg/day) are meeting the dietary requirement. An estimation of the safe and adequate daily dietary intake for Vitamin H was made for the first time in 1980 by the Food and Nutrition Board of the United States National Research Council. The present recommendations in the USA are 20-30 µg daily for adults and children over 11 years, and 5-12 µg daily for infants and younger children. France and South Africa recommend a daily intake of up to 300 µg, and Singapore up to 400 µg biotin. Others, including the Federal Republic of Germany, assume that diet and intestinal synthesis provide sufficient amounts.
