Makes my hair, skin, nails - softer, nicer and stronger. 1) Smells horrendous and tastes very gross. Tried it with a 12 ounce glass of lemonade and did not notice a thing. Glad to have found this method for downing it. 2) When I took about 12 drops at one time, my stomach felt like I had an indigestion. So will stick to just 6 drops twice a day. 3) The liquid outperforms the tablets. The tablets are easier to take and do not stink. 4) I'll always stick with this liquid form. I'm not sure if I want to try out their other stuff as this is working so well for me. 5) My hair is stronger and it's looking thicker. I am convinced that my hair growing faster than ever. 6) Great improvement in my skin. Yes, there is a difference also the fine wrinkles are looking better. My girlfriend say it's looking better. Results of softer and glowing skin is immediate. 7) Nail - definite improvement ! Now, I have stronger and fast growing nails than ever. Just a few days and I have to cut them, because they are too long :)) Finnally, do not forget that collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But starting at age 21, collagen diminishes 1% per year. By age 30, the signs become visible. But to counter this we need collagen generator. Everyone knows that collagen is composed of three major protein: collagen, keratin, elastin. Collagen "plumps out" skin, removing wrinkles and preventing them from forming. In addition, collagen is essential for strong, healthy bones and joints. Keratin is the protein that's packed into your hair shaft. It gives your hair thickness, body, strength, and elasticity. Plus, keratin gives your nails strength. Elastin gives your skin its ability to stretch and "bounce back" preventing fine lines and wrinkles. I'm very glad that I found this product. Biosil have given me lovely nails, nicer skin and hopefully better hair. Highly recommend this product !

Wow, definetely helping with fine lines around eyes, and my acne scars are MUCH less visible! I couldn't realise why. But then I though it must be it, since I am not using any other supplements or special creams. I was using it on and off for couple weeks and didn't see much difference, and was thinking why everyone was so happy about it. But only after 2 weeks everyday use I've seen huge improvement. Please feel free to click "yes" if you find my review helpful for you. Best wishes

If you're anything like me, you've probably spent several hundred dollars (if not more) on supplements over the years, only to discover that three-quarters of them appear to make little or no discernable, tangible, difference to your health, despite the claims of the manufacturers. I am very pleased to say that, for me, Biosil is a very notable exception to this trend. This stuff works. I'll say it again: THIS STUFF WORKS! I have close-shaven hair (about 1/8" long)and because of this, it is readily apparent to me when my hair has changed because any difference in stiffness makes it much harder to run my hand over. Whenever I stop using Biosil for a few weeks and then return to it, the difference in strength of my hair is quite startling. I highly recommend this product if you suffer from silicon deficiency (most people do), and I also suggest you look into Kervran's book 'Biological Transmutations', which is hard-going but discusses the concept of transmutation of minerals. While this concept has yet to garner wide-spread acceptance, there is good sense behind it and it points to the possiblity that silicon can be used by the body for many purposes other than those directly pertaining to silicon in its basic form. That Biosil makes silicon so abundantly-absorbable for the body, only adds to its potential.

... and am happy to report that I've seen positive results in approx. 3 weeks, in that my curly/coily hair doesn't seem to shed as much during styling, and my nails are growing stronger. I use quality beauty products and am permanently adding this to my regime.

This review may be a bit premature because I've only been using the Biosil for a couple months, but: my nails are growing at an alarming rate (a disadvantage, for me) and my hair already seems to be thicker. Not thicker as in more hair per sq. inch, but each individual strand seems thicker and healthier. This is noticable primarily near the scalp, so I'm guessing the Biosil must already be affecting the new growth. The clinical studies showed differences at the 5 and 6 month mark, so I'm not expecting overnight miracles, but seeing a small improvement so quickly is nice. The liquid Biosil has a horrendous taste, so I bought the Now Foods empty capsules and take it that way - makes life a little easier.
