How many micrograms is equivalent to 20mg of this product?

Thank you for your interest in Puritan's Pride Ultra Mega Biotin 10, 000 Mcg (B51463)! 10,000 mcg equals10 mg. Therefore 20,000 mcg equals 20 mg.

I can read the label. I would like to know what is the source of the biotin?

Thank you for your interest in Puritan's Pride Ultra Mega Biotin 10,000 mcg (Prod No. 51463, B51463) . The source of biotin is ketenes.

Just to clarify is this 3 bottles with 100 softgels of 10000 mcg Biotin in each bottle? The product says 300 but the photo is for 1 bottle with 50

I don’t know but just as a thought if it says 2 times a day then 100 pills would be 50 daily servings. I used mine up several years ago. Be sure to read back label.
