Considerations

The U.S. Recommended Dietary Allowance for adults is 300 micrograms per day. As a water-soluble vitamin, biotin is not stored in the body, and there is less of a risk of toxicity when compared with fat-soluble vitamins. There is no upper tolerable limit intake for biotin, as determined by the Institute of Medicine at the National Academy of Sciences.
According to WHFoods, almost half of all pregnant women might be biotin deficient in the first and third trimesters. Biotin deficiencies can lead to birth defects and skin problems, including cradle cap in infants.
