BioSil Orthosilicic Acid is rated 4.7 out of 5 by 17.
Rated 5 out of 5 by from good deal I took this product for a period of time and then I ran out and neglected to order it. I am back on it again and not sure what it is doing for bone density but my hair and nails look stronger and I believe it is a good indicator. Will keep taking this and ordering through Swanson when I place my regular orders for all my organics. Love this company!

Rated 4 out of 5 by from Effective Product One of the few supplements that actually assist nail and hair growth. Despite the taste, I prefer the drops over the capsules. Takes a few months to see results, but worth the wait. Big difference when I take a hiatus.

Rated 5 out of 5 by from Very Effective! This product keeps you young looking and your hair is thicker and your nails and bones are stronger. A must have!

Rated 5 out of 5 by from Combat the taste for the great benefits I use empty gelatin capsules and drop the drops into that. Works great. The capsules also come in vegan if you prefer that. I've taken this for years. It really makes a noticeable difference to hair/nails.

Rated 5 out of 5 by from fingernails I have problem fingernails. They seem to be much better when I take this supplement. It is easy to use too.

Rated 5 out of 5 by from Faster hair growth than ever I have tried Biotin and received no results but with BioSil my hair has been growing about an inch or more a month when normally it grows 3 quarters of an inch a month.

Rated 5 out of 5 by from Helps my skin I've noticed that my skin is smoother and not so dry looking since I started this product a couple months ago.

Rated 4 out of 5 by from High quality and convenient I've used this product for years together with other products for joint protection. The 1oz. dropper bottle is the best buy.

Rated 5 out of 5 by from Very good price compare to Ultrasil My hairs get fuller, my nails get stronger since I started using biosil 6 years ago. I mix it in my oatmeal to reduce that metal smell.

Rated 5 out of 5 by from very good product I have been taking this for several months now, twice a day, 5 drops each time. It indeed improved my hair and nails, and I keep taking it. An unexpected benefit was that all my life I had been picking on my nails and had not been able to quit, but after I took BioSil for a while, I found myself not doing it anymore, without trying. The only thing that cannot be avoided is that the taste is not pleasant. However, it is most noticeable if the drops are put in water. If I use some sour juice instead (e.g., tart cherry, pomegranate, etc.), I do not notice the taste.

Rated 5 out of 5 by from This stuff works! May hair and nails are strong and grow like weeds. Yes, the liquid tastes bad, but if you curl up the end of your tongue a bit and put the drops in there, then take a swig of liquid and swallow, you don't taste it. Evidently the tip of the tongue does not have taste receptors for this. This is much easier than putting it in water or juice or whatever and then having to drink a whole bunch of nasty flavored stuff.

Rated 4 out of 5 by from works for me although it tastes bad,need to mix it with something other than water. i believe it has helped me.

Rated 3 out of 5 by from BioSil drops I have taken the tablets and they are great! I accidentally ordered the drops and they are the worst tasting stuff I have ever had! Don't buy it unless you are a glutton for punishment!

Rated 5 out of 5 by from tried and true been taking biosil for years, back to when jarrow was bottling it. i think it is the same orthosilicic formula, because my nails and hair have stayed in great shape. sure it tastes funky, but you will get past that part of it once you start seeing the benefits
Date published: 2012-03-23
Rated 5 out of 5 by from fingernails are long and strong. Hope it is helping my bones also because that is why i am taking it.
Date published: 2011-10-16
Rated 5 out of 5 by from I Just Can't Say Enough! I took this product a couple of years ago, along with ConcenTrace Liquid Minerals. My fingernails finally grew stong, but I stopped taking both of them. I decided to order some of this silica again, and after the very first dose, I felt better! I'm not kidding. Most products, even when you need them, won't do that! Now I've resumed the minerals AND regularly taking this Bio Sil. Orthosilicic acid is REALLY important, especially for strong bones. And fingernails are a good reflection of what's going on INSIDE your body.
