I love that I don't have to chew these

I used the chewable biotin for about a year and had great results with my thining hair and brittle nails. I tried to reorder and they out of stock, so I purchased these. They work equally as well and they are a pill that I can swallow. I do not like chewable vitamins. I have recommended these to my friends with similar hair and nail issues

Good value and convenient

I just started taking it. But I like that I only have to take one capsule a day and not 3 or 6 like some other brands.

Good value

This is a good value for the money. There were a lot more pills versus a bottle bought at a nutrition store for a similar price.

Biotin pills value

I like using the biotin pills. Honestly if I didn’t get almost a year worth grown Sams I wouldn’t take them. Very expensive else where.
