Is this product Gluten free?

Sorry, I don't know. I feel this is a great product but I don't have gluten intolerance so that's not something that's high on my radar. Sometimes you can email the company right from Amazon...? Good Luck!

Is this a natural Biotin or synthetic D-biotin ?

They say all their products are natural.

How many pills each day?

I take one per day & I take it before bed. I've read Biotin may help with sleep. I like this brand a lot.
