dietary supplementation
"I started taking this vitamin because my hair was rapidly falling out. Two weeks I have been on the vitamin, and for the entire two weeks my stomach was extremely upset. Diarrhea, upset stomach, sore throat, and skin rashes occured. I have never had any allergic reaction, or even side effects to medication or vitamins, until this. To top it all off, I have noticed not a single change in hair, skin, or nails. Be wary of this product, and at the very least, keep an eye out for symptoms."
