Our Pick
Natrol Biotin
Natrol biotin is one of the most popular biotin brands on Amazon. With 10,000+ reviews, there are numerous reviews and amazing hair growth results.

Natrol Biotin is so popular on Amazon for number of reasons.

First, it costs less than $10 for 100 tablets (which is contained in one bottle). As you only need to take it one tablet a day, it will last more than 3 months. In other words, it only costs about $3 per month.

Biotin supplements are usually available in various dosages from 500, 1000, 2000, 5000, and 10,000 mcg. What we also love about Natrol Biotin is that it offers the maximum dosage in each tablet (10,000 mg)

We know what you’re thinking: “Isn’t 10000 mg too much?”

Since biotin is water soluble, you can’t overdose on it. Your body will naturally remove any excess amount. If this is your first time trying biotin and still worried about the high dosage, try it with smaller dosage (5000 mcg) instead.

Natrol Biotin reviews from actual users

Some people take biotin for faster hair growth. However, most are taking biotin because of hair loss.


Natrol Biotin for Hair Loss: A large number of reviews mention that after taking Biotin from 6 to 8 weeks, they did see their bald spots were filling in with new hair. Make sure to check customer photos on Amazon. Before and after transformation for hair regrowth are truly amazing!

Also, a number of users noticed thicker and fuller hair after taking biotin. (Keep in mind the noticeable difference started from 6 weeks of usage. In other words, you can’t expect instant results with hair vitamins like Biotin).


Some people commented that they didn’t see hair regrowth- instead, they noticed faster hair growth.

Other reviewers say that biotin gives them cystic acne and increased breakouts on their facial skins.

One way you can avoid acne is to drink lots of water (at least 4 glasses a day). This will make it easy for your body to flush it through the system and clear up any existing skin breakage.
