Customer Ratings & Reviews

Rated 4.6 out of 5 by 36 reviewers.
Rated 4 out of 5 by Like this product I can't see a huge difference in growth of my hair or nails but I also haven't given up on it for about five months. I feel like I should switch and will once this bottle is done. September 30, 2016
Rated 5 out of 5 by Good quality - good pricing It is a little too early to tell for sure - but the product seems to be as effective as other Biotin I have purchased elsewhere and is at slightly better pricing. March 17, 2016
Rated 5 out of 5 by Hair, Skin, & Nails This is an amazing product for your hair skin and nails. I recommend this to all of my clients because I am a hair stylist and I know from experience the benefits of taking this regularly. Even if you take it twice a day I have seen it work most effectively then. If you take it too late it might give you energy or could have trouble sleeping but I take mine at breakfast and lunch with food. February 4, 2016
Rated 5 out of 5 by Love this a must use. I have been using this product since last year and it has grown my hair and made my nails stronger. I would recommend this to a friend. July 12, 2015

Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by Seems to be good for my skin and hair April 4, 2013
Rated 5 out of 5 by great product I think it works because I can tell a difference in my nails April 3, 2013
Rated 5 out of 5 by 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
Rated 5 out of 5 by I think my hair growth is improving. It seems like my hair growth has improved since taking Biotin Maximum Strength. March 16, 2013
Rated 4 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by Great product This product is easy to take & I believe it will be effective..... February 21, 2013
Rated 1 out of 5 by 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
Rated 4 out of 5 by 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
