Comments about GNC Biotin 5000mcg, Capsules, 240 ea:
I find it is a great help with keeping my nails strong and preventing splitting and breakage that seems to have become a problem as I am no longer in my 30's. I have recommended it to several friends who have seen similar improvement. I have also seem a slight improvement in my hair, but not as marked as my nails.
Bottom Line Yes, I would recommend this to a friend
