Current recommendations for biotin by the Institute of Medicine state that the daily adequate intake (AI) for adults is 30 μg/day . Most healthy individuals meet these requirements through a well-balanced diet, though many still take up to 500–1,000 μg of biotin supplementation daily.
Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date. Reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.

Collagen appears to be a bit more impactful for hair growth than biotin. “Biotin helps provide the key energy needed to power hair production. It is only a part of supporting hair growth,” says Dr. Anzelone.

We observed that long-term administration of biotin decreased systolic blood pressure in the SHRSP strain; also, a single dose of biotin immediately decreased systolic blood pressure in this strain.
A biotin deficiency can often reveal itself in weak facial hair growth or patchy beard growth. Although Biotin is often touted as a wonder hair supplement, but too high a dosage of Biotin can lead to acne, incensed sugar levels, slower release of insulin and skin reactions.
