This product is said to help restore strength and radiance to your skin, hair, and nails.

Natrol Biotin is available in tablet form. The manufacturer suggesting taking one capsule daily with meals. Since there are a variety of dosage options available, we suggest sticking to the 10 000 mcg option as studies have shown that lower doses of biotin may be ineffective for desired results.


Unfortunately, the manufacturer does not sell these items directly from their website, they only offer a list of authorized third-party retailers which sell these products for $6.00 to $17.95 depending on the strength you choose. Each container contains 100 tablets and some retailers offer 2 bottle supply specials. You would need to shop around on each of these websites in order to get the best price. It seems that the official website has a coupons page hidden in the footer which you could use when purchasing this product. We cannot confirm if these coupons are applicable to all products and if they will work on third-party sites.

Possible Side Effects

While the manufacturer has not mentioned any side effects associated with taking this product, it is always advisable to consult your doctor before taking any supplements especially if you are pregnant or have any known medical condition.

Manufacturer’s Commitment

We were unable to find any policy that mentions refunds or guarantees on the official site. Some sites have included a legal disclaimer which states that any warranty, implied or otherwise, is separate from and unknown to Seller. We cannot confirm if third-party distributors will refund you if you are not satisfied with the quality and effectiveness of this product. While there are a variety of mixed reviews, we were unable to find any that have mentioned that they have successfully received a refund from the manufacturer or seller.

Natrol Biotin Review – The Bottom Line

We appreciate the fact that this product is natural and that it comes with a 10 000 mcg strength, however, we do have a few concerns.  The first concern we have is that this product includes calcium, evidence reveals that biotin should be the only active ingredient in order for the product to be effective. We are also disappointed to see that the manufacturer does not sell these products directly from its website, it is a hassle to compare prices especially when there are so many authorized sellers who are selling this product at various prices. There is an abundance of mixed reviews and many of consumers who have felt this product was ineffective have complained about how this product has caused breakouts and their acne to worsen. Our final concern is that the manufacturer has not given any confidence in their formula based on the lack of the manufacturer’s commitment and guarantee. The information on the official website is very limited and has not provided us with enough evidence to back up the manufacturer’s claims.
