Each tablet of Natrol Biotin provides you with 66 mg of Calcium and 10,000 mcg of Biotin (3,333% of your Daily Value). The tablets are soy-free, gluten-free, and wheat-free, and are designed to support cellular energy for healthier hair and strong nails.

But how can you be sure that 10,000 mcg is a safe dose to start with? Almost all Biotin supplements deliver 5,000 mcg per serving, but Natrol and Nature’s Bounty both have products with 10,000 mcg per tablet.

In this review we compare the Natrol product to two other top-rated biotin supplements; Nature’s Bounty Biotin, and Zhou Nutrition Hairfluence. Comparisons include the ingredients, dosages, cost per serving, price, and customer feedback.

We’ve also added recommendations for the best multivitamin to combine with Natrol Biotin. This is so you can maintain a healthy balance between your vitamin, mineral, Omega-3, antioxidant, and probiotic intake.

Natrol Biotin Ingredients

Currently ranked as the bestselling biotin supplement on Amazon, Natrol Biotin 10,000 mcg represents excellent value for money.

In terms of the ingredients, Natrol have kept it simple, adding only 66 mg of calcium per serving to aid in the formation of healthy bones and teeth.

Natrol are also one of the only supplement companies to combine these ingredients in tablet form. Most companies, such as Nature’s Bounty, Spring Valley, and Nature Made package their biotin inside softgels.

Although many people believe the softgels are easier to swallow, due to the small size of the Natrol tablets, there’s really not much of a difference. By using tablet form rather than a liquid, this also means there’s no need for a protective coating.

Each of the companies we just mentioned use softgels as a delivery system, but they also use gelatin and soybean oil. Gelatin means they’re not suitable for vegetarians or vegans, while some studies have shown soybean phytates to limit absorption of key minerals into the body.

In place of these ingredients, Natrol uses cellulose and glycerin, with no animal derived products or byproducts whatsoever. This makes it an excellent choice for anyone needing a high daily dose of biotin, including vegetarians and vegans.

Other ingredients: Cellulose, stearin acid, silica, magnesium stearate, methylcellulose, cellulose gum, glycerin.

What sizes are available?

With a serving size of 1 tablet, each box provides you with 100 servings. Following the recommended daily dose of 1 tablet per day, this should be enough to last 100 days.

At the time of writing this review, the best value for money comes from the multi-pack offer on 4 bottles from Amazon. Each serving was priced at $0.06, compared to $0.08 per serving for the single bottle of 100 tablets. That’s a 50%+ saving on the Omegaboost Biotin, for a tablet that offers double the dose (10,000 mcg).

This is why we always recommend calculating the average cost per serving, across all sizes, before making a final buying decision.
