Biotin Maximum Strength is rated 4.6 out of 5 by 39.
Rated 5 out of 5 by from Works Love how it has improved the look and health of my nails. As for my hair, I haven’t noticed anything really, but it’s pretty healthy anyway. Maybe after a haircut I’ll notice some change/improvement.

Rated 3 out of 5 by from Wait and see I just started taking this brand of biotin and seems to be working. Nails are a little stronger. Took the Swanson's brand for quite a while, but nails were not getting strong enough to where they would not break. Will wait and see if this brand works better.

Rated 5 out of 5 by from Work much better than anticipated I have never taken a separate biotin supplement before so I was skeptical as to what benefits I would really receive. I was surprised and pleased to learn that after regular use (over several weeks) my thick hair became much less dry and more shiny. I have also noticed my nails seem to grow faster and have more strength than I previously remember. I can't say if these contribute to healthier skin because I use other topical products in addition to biotin for face and body. I definitely think I will continue to add biotin to my daily vitamin intake.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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!
