Great product Love this product, has really helped my hair and nails look better. June 5, 2013
Wonderful product if you are in need of this much biotin. It seems to work wonderfully and at an O.K. price thanks to Swanson's. May 21, 2013
For fast growing hair ;) Made my hair grow longer really fast. Originally bought this because I busted my fingers and nails in a door jam :<! Nails grew back very quickly & as a bonus my already long hair grew at least 2 inches more in one month. (btw I trimmed my hair the week before taking biotin- I also use Life FIo pure Argan Oil in my hair and face as well.. that is great stuff also.) I take this in conjunction with Omegas, Alive! (the women's once daily), vitamin c, calcium with d, and a few other supplements. My hair is healthy, bouncy, shiny and long :)!! Oh! Not to mention my nails grow faster now too. Stronger nails?... maybe. can't tell... maybe a little. April 21, 2013
Love this! I've been using the Biotin Maximum Strength for over a year now and I love it. I wanted to find something that would help my hair and skin and this is it! April 18, 2013
Seems to be good for my skin and hair April 4, 2013
great product I think it works because I can tell a difference in my nails April 3, 2013
Actually works for hair growth. There are only a few supplements that I actually notice a difference with when I take them. I usually just hope they are working. After using this high dose of biotin I have noticed that my hair has grown faster. April 1, 2013
I think my hair growth is improving. It seems like my hair growth has improved since taking Biotin Maximum Strength. March 16, 2013
Most Cost-Effective Choice on the Market This is my THIRD bottle, as they say "Three times for EMPHASIS!" I have told all of my friends about the product and Swanson's Vitamins. Even when you google Biotin pills online, Swansons came up hands down as the most cost-effective and I love a good bargain. This is also a quality product. I have seen fast hair growth within six months. My nails and hair has grown with the products' use. Try the results for yourself TODAY! March 12, 2013
Love it! My nails have grown nice and strong. My hair has also shown growth and My skin is much clearer. I will be using this forever, March 11, 2013
GREAT VALUE Biotin Maximum Strength G This is how vitamins should be sold, on the Net: In large quantities, and higher doses, for greater value and landfill reduction, for a great price If you require, Biotin in your diet, and who doesn't, Maximum Strength, Biotin is your wiser choice, with the good pill count per bottle, and wow, 10,000 mcg, 10 MG and don't forget to pair this up with your Folic acid, Paba, B12 and B6 March 9, 2013
Great product This product is easy to take & I believe it will be effective..... February 21, 2013
Break outs galore Can you imagine? i got pimples everyday from taking this product. EVERYDAY. My face needs extra TLC just for my skin to look good again. I see it did something for my nails but nothing for my hair. So upset. February 13, 2013
I got it to promote faster hair growth but doesn't see like much is happening there. My finger and toe nails on the other hand have taken off like wild fire. Since it's suppose to promote hair and nail growth it's doing what if states. Just wish the hair growth was quicker. December 11, 2012
The best!!! Hello, I just wanted say that natrol biotin 10,000 mcg. is the best. I have nothing but great results from this product. This is my second bottle that I've ordered with Swanson and my nails and hair are and still is growing!!!!!!!!!! Thanks Natrol for this amazing product..... August 23, 2012
Maximum Strength Biotin This is a great product . I was looking for Biotin in a higher strength and was very lucky to find Biotin in this 10,000 mcg maximum strength form here on Swansonvitamins.com and it is a great price for 100 pills per bottle . June 17, 2012
i will admit, i was a bit nervous to take such a high mg of biotin, but my nerves were eased the moment i started to take this! love the way it's improved my hair & nails! :) May 6, 2012
Not as good as liquid caps I like taking Biotin and think it definitely helps with my hair. However, I don't think this is a good one to take. These are tablets, like coated chalky tablets. In my experience, liquid caps work MUCH MUCH better, even in a lesser strength. I had some liquid caps from Wal-Green's that I used for awhile and my hair looked GREAT. I switched to these because I thought the higher dose would be better and my hair went back to the way it had been before. Not any better at all. Get liquid caps for Biotin. They work a LOT better. March 28, 2012
Great Product I just started using this product , I want to see if it is true that the B vitamin Biotin can cause my hair to grow stronger , this is the strongest Biotin on the market , I which they had it in 50mg. tablets, I would purchase it even faster . March 23, 2012
Just started using it People my age lack in the B vitamins, this seems to be helping March 16, 2012
Best Solution Lately, I have noticied some hair damage which includes breakage and, brittleness. I decided to purchase the necessary vitamins that would be able to help me. So far, I have noticed hair growth and sheen back to my har. September 10, 2011
