I ordered this product on advice that it would help my hair stop breaking off. I've been using it for a few weeks, and I can't say for sure if my hair is better, but my knee sure does not hurt anymore!

My wife has had pain in her elbows off and on for nearly two years. She has been taking biosil for 6-8 weeks, and she says it is making a difference on the elbow pain. Further, she thinks her hair (stopped falling out), nails and skin are better.

I have used this product for several months. I am 54 and a weekend athlete. I use it to relieve general aches in my knees from workouts and runs. I am not nearly as stiff when I use it, but if I forget to use it the second day I of not using it I really notice it in my knees and shoulders.

it isn't magic in a bottle or anything for me, but my hair is in fact growing faster and thicker/stronger than before I began using it. I will stick with it for a year in order to get the results I seek. The taste is very strong/unpleasant in water but I find the tiniest bit of any kind of juice totally masks it. The taste isn't as offensive as many of the reviews say if you are used to taking rather foul-tasting supplements or multi-vitamins.

Taking 5 drops 2x/day. Mixing in a small amount of warm water before adding a bit of cold oj is working fine to dissolve it and mask the taste. I tried it this a.m. with a different juice and it was not tasty. lol but in general it's not meant to be savored like wine so if you slug it down it isn't as bad as other users have made it sound. As for the results, it's only been a couple of weeks. But I do think I am beginning to see some improvement in overall texture of my face and a nice subtle glow, and no digestive upset or acne, etc. side effects. I am also taking New Chapter's Wholemega wild salmon oil, the combination seems to be working. Hope to see increased benefits over time. Will continue to take.
