My hair has started falling out and I hope this makes it stop. Highly recommended and I like the Jarrow brand.

I have only been using the product less than a month so it is too soon to know if I have benefitted; however, I am getting low and plan to reorder soon. My daughter and I are sharing a bottle. I must say that I was warned that the taste would not be favorable. We tried it in cranberry juice, apple juice and finally orange juice. We both agree that orange juice is the winner, hands down. On one occasion, I had the unfortunate opportunity to take it with water; no juice available. It was a lasting memory, so juice is always availble.

I have used this product for over two months, and am finally starting to see a slight improvement in my nails. I see no difference in my skin or hair at all. The change has been so slight and gradual that it is almost unnoticeable. The taste and smell of this liquid is so horrible, that it is difficult to disguise, even in juice. I will continue using it for another month, and make a decision on whether or not I will continue to use it.
