Another supplement..: Biotin deficiency is rare, but can occur in persons with genetic mutations, on long-term antibiotics or anti-convulsants, or who eat a lot of raw egg whites. There is no good evidence that this over-the-counter supplement is needed, because normal people eating a regular, balanced diet should get enough of it from their foods.

Vitamin: Mostly used for hair and nails. Most people have no side effects except maybe urine color change or odor.

Is 1mg of biotin a lot?

Biotin: Biotin is vitamin b7, and is water-soluble. It most often comes in "mcg" doses -- there are 1000 mcg in 1 mg. Deficiencies are rare, as daily needs are small (around 50 mcg/day in adults) and it's abundant in food. Long-term antiseizure meds or antibiotics, intestinal malabsorption, & eating raw egg whites can lead to biotin deficiency. If you have one of these issues, 1mg is okay.
