According to the Food and Nutrition Board of the Institute of Medicine of the United States National Research Council in 1998, it has set an average adequate intake levels (Al) for Biotin for the adults up to 20 to 30 micrograms per day. However the appropriate dose for Biotin or Recommended Dietary allowances (RDA) has not been established due to the insufficient information to determine an appropriate range of doses for Biotin.
The following list gives you a brief glance on adequate intakes (AI) for Biotin are :
- From newborns to 12 months of age, 7 micrograms of Biotin is required per day.
- For children between 1 to 3 years of age, 8 micrograms of Biotin is required per day.
- For children between 4 to 8 years of age, 12 micrograms of Biotin is required per day.
- For children between 9to 13 years of age, 20 micrograms of Biotin is required per day.
- For adolescents of age between 14 to 18 years, should get a Biotin of 25 micrograms per day.
