Not just tested—clinically proven

Biosil's benefits are clinically proven in unbiased, independent clinical studies conducted by leading European, American, and British university researchers. These studies are double-blind, placebo-controlled, and randomized. In other words, using the gold standards of scientific research, international scientists have documented statistically significant and clinically relevant results for hair, skin, nails, joints, and bones.†

And that's excellent news because that means that Biosil® is proven to work. These studies were conducted using Biosil® products. The results cannot and should not be applied to other brands.†
