How much biotin should you take daily?

I found a chart that gives dosages according to age... Biotin in higher doses might be prescribed by your doctor. There is no known amount that is "too high" but you shouldn't ever chance taking a higher dose unless your doctor tells you to!

0-6 months

5 micrograms/day

7-12 months

6 mcg/day

1-3 years

8 mcg/day

4-8 years

12 mcg/day

9-13 years

20 mcg/day

14-18 years

25 mcg/day

19 years and up

30 mcg/day

Pregnant women

30 mcg/day

Breastfeeding women

35 mcg/day

Hope this helps :)
