The 13 Best RD-Approved Biotin Supplements

If you’re looking for an affordable, high-dose biotin supplement, it’s hard to beat Just Nutrients Biotin Gummies. At around $10 for 100 gummies, it’s one of the most affordable options we could find. They’re gluten-, dairy-, and soy-free, making them suitable for a variety of dietary needs. They’re also gelatin-free, so they’re a good choice for people following a vegan or vegetarian diet.

These biotin gummies are manufactured in a CGMP-compliant facility, ensuring they’re produced, processed, and packaged to high standards of safety and purity. They also contain 3 grams (g) of sugar per two-gummy serving, so keep this in mind if you prefer to minimize your sugar intake.

Of all the biotin supplements we reviewed, Pure Encapsulations Biotin stood out as the best biotin capsule for several reasons. First, reviewers note that these capsules are small and easy to swallow. Plus, a dose is only one capsule, which makes it easy to incorporate into your daily routine. This biotin supplement contains 8,000 mcg of biotin, making it a high-potency option. It is formulated to support metabolism and nail strength.

All Pure Encapsulations products are free from common allergens such as gluten, soy, eggs, tree nuts, peanuts, and dairy. They’re also vegan-friendly, making them a great choice for all diets.

Pure Encapsulations products are also free from artificial colors, flavors, and sweeteners, and they contain no coating, shellacs, or unnecessary binders, fillers, or preservatives. This makes them ideal for people with sensitivities to additives and preservatives. They’re also tested for purity and potency by third-party laboratories such as Eurofins and Advanced Laboratories. This ensures that the supplements only contain what’s listed on the label.

Finally, we loved that Pure Encapsulations aims to reduce plastic consumption by removing unnecessary plastic packaging. Plus, they partner with TerraCycle to recycle packaging that isn’t accepted for municipal recycling. To recycle with TerraCycle, you create a TerraCycle account, collect your Pure Encapsulations supplement bottles, print a free shipping label, and send your box of collected supplement bottles to TerraCycle to be recycled.

Liquid biotin supplements may be easier to consume for people who have difficulty swallowing pills. And because it’s liquid, you can easily adjust the dose by changing the amount you draw into the dropper. On the label for this supplement, you’ll see that the dose is measured in micrograms (mcg), not milligrams (mg). Biotin supplements use both units of measurement, so you might see “mg” or “mcg” on different supplement labels. It’s important to check and understand the difference, because 10,000 mcg is equivalent to 10 mg.

It’s also vegan-friendly, non-GMO, and free from several common allergens. It comes in a natural berry flavor, which may make it more palatable for some people. Finally, all Carlyle Nutritionals products are produced in a CGMP-compliant and U.S. Department of Agriculture (USDA) organic–certified facility. The manufacturing facility is also audited by the FDA. While not third-party tested, Carlyle Nutritionals products are tested for purity, potency, and composition in an in-house microbial lab.

Nature’s Bounty Hair, Skin & Nails Gummies are more affordable than a lot of the other biotin gummies on the market. They’re available at several online and in-person stores and are an easy-to-take option for those who can’t take pills.

These gummies are free from artificial flavors and sweeteners. The strawberry flavor makes them a supplement most people will enjoy taking. They’re also free from common allergens like dairy, soy, gluten, and fish, so they’re suitable for people with a wide range of dietary restrictions.

Because these gummies contain gelatin, they’re not suitable for those following a vegan or vegetarian diet. They also contain 2 g of sugar, which could be an issue for those watching their sugar intake. While these factors may deter some people from using this supplement, we still feel that it’s a solid choice. Reviewers said it’s effective for hair growth, nail strength, and skin improvement. People also note the gummies taste good and are easy to take.

While biotin gummies are a popular choice, people watching their sugar intake may prefer a sugar-free option. We love Nature Made Zero Sugar Hair Skin Nails Gummies because they have no added sugar, are vegan-friendly, and contain no gluten or aspartame. They’re also free of synthetic dyes and artificial flavors, so they’re a good option for people who prefer to avoid these additives.

While these gummies are not third-party tested, Nature Made is a well-regarded and well-established brand, so we still feel comfortable including them on this list.

Since a dose of these gummies only contains 3 g of sugar alcohols, most people (with the exception of people with irritable bowel syndrome, who may be more sensitive to the effects of sugar alcohols) should tolerate them.

We didn’t find many powdered biotin supplements during our search, but this one stood out because the powder format allows for the customization of doses. It also contains just one additional ingredient — dicalcium phosphate (a filler) — making it a good choice for those seeking a shorter ingredient list. It’s also affordable compared with other powdered biotin, and it’s third-party tested and manufactured to CGMP standards.

There are a couple of downsides to using a powder over a capsule. First, it may be difficult to accurately measure the powder, which could lead to not taking the correct dosage. Since the product doesn’t come with a scoop, you’ll have to use a teaspoon instead. Also, some reviewers on Amazon noted that it has a slightly bitter taste and does not dissolve well. However, if you mix it into a smoothie, coffee, or juice, it will likely mask the bitter taste.

Doctor’s Best Biotin offers 10,000 mcg in a plant-based capsule that’s suitable for people following a vegan diet. While the price varies significantly depending on where you buy it, it was still one of the most affordable supplements we reviewed.

Doctor’s Best is transparent about its ingredients. All of its supplements are third-party tested and produced in a CGMP-compliant facility, ensuring that the product you receive is pure and contains only the listed ingredients.

In addition to being USDA organic certified, MaryRuth’s Organic Hair, Skin & Nails Gummies are third-party tested by Clean Label Project, ensuring they’re free from harmful contaminants. Plus, as a Certified B-Corporation, the company meets high standards for social and environmental responsibility.

We also love that because these gummies don’t contain gelatin, they’re vegan-friendly. They’re also nut-free, making them a safe option for people with nut allergies. They do contain 4 g of added sugars per two-gummy serving, so keep this in mind if you’re watching your sugar intake. Although many reviewers enjoy the strawberry flavor, it’s the only available option, so it may not appeal to people who don’t like strawberries.

For those looking for a biotin supplement with a short ingredients list, Thorne Biotin has just five ingredients (including biotin). It’s gluten-, dairy-, soy-, and yeast-free, so it’s a good choice for people with allergies or sensitivities to these ingredients. While the brand doesn’t specify whether this supplement is vegan-friendly, it contains no animal-derived ingredients.

We loved that a dose is a single capsule, making it easy to incorporate into your daily routine. That said, some reviewers noted that the capsules were large and difficult to swallow, so keep this in mind if you struggle to swallow larger pills. Some also wrote that these biotin capsules did not help with hair loss or nail health. However, this is a common complaint with biotin supplements and not specific to this product.

They’re health savings account (HSA) and flexible spending account (FSA) eligible, too, so you may be able to try them for a relatively low cost.

Nutrafol is manufactured in a CGMP-compliant, FDA-registered facility. The final products are tested in-house and at a third-party laboratory to ensure that the supplement contains only what is listed on the label.

All NOW products are manufactured in a CGMP-compliant facility, meaning they’re produced under strict quality control standards, ensuring consistency, safety, and compliance with FDA supplement regulations. This product contains beef gelatin, so it’s not for vegans or vegetarians — but NOW does have a similar product that is vegetarian and vegan-friendly.

We chose Sports Research Collagen Beauty Complex because, in addition to biotin, it contains several ingredients that research has shown to promote skin health, such as collagen peptides, vitamin C, and hyaluronic acid. Hyaluronic acid is part of all the connective tissues and organs in the body. While hyaluronic acid is often used topically to improve skin appearance, less is known about the effects of oral hyaluronic acid on wrinkles and skin moisturization. A balanced diet containing healthy fats, lean proteins, and fiber is also important for glowing skin.

Nutricost supplements are manufactured in a CGMP-compliant facility and are third-party tested, ensuring quality, purity, and potency. While some people noted they didn’t like the flavor of this supplement, that could be masked by adding it to a smoothie or juice instead of water.

Webber Naturals Collagen30 With Biotin is free from common allergens and non-GMO, and it’s gluten-, dairy-, and sugar-free. Webber Naturals products are tested for quality and safety at several steps through the production process. Each ingredient must meet high standards for potency and purity.
