Spring Valley - Biotin 1000 mcg, 150 Softgels.

I wanted to know spring valley biotin softgels 1000 mcg gelatin source?

what is the expiration date???

It plainly states that the spring valley 1;000 mcg biotin are tablets, but bottle reads softgels. why have you not corrected this?

does spring valley biotin 10,000mg. contain aluminum or any heavy metals?
