The top biotin supplements for 2025: Brands you need to know and try

As the saying goes, beauty starts from within – and your diet and the nutrients you consume are just as important as the topical lotions and potions you use to keep your hair, skin and nails looking their best.

Biotin is one of the most talked-about supplements for those looking to enhance hair growth, strengthen nails, and support healthy skin. Often referred to as vitamin B7, it plays a key role in energy metabolism and the maintenance of keratin structures, supporting shiny, healthy looking hair and a clear, radiant complexion. But, with hundreds of products available, finding one that actually delivers can be challenging.

To make the task easier, we’ve curated some of the top biotin supplements to consider adding to your routine, based on quality, formulation, and trust – and broken down all of the finer details so you can decide which one is right for you.

1. Nutrition Geeks (Top Choice)

Nutrition Geeks earns the number one position for 2025 thanks to its precise formulation, clean ingredient profile, and outstanding customer satisfaction. The brand’s Biotin Growth+ supplement provides a balanced 10,000 micrograms of biotin alongside supportive nutrients such as zinc and selenium, which together work in synergy to enhance the visible benefits of biotin for hair and nail strength.

With a focus on ingredient transparency and manufacturing integrity, each batch is produced under strict GMP standards and undergoes third-party testing for purity. The dosage instructions are simple and practical: two tablets per day, taken with food. Users report stronger nails within weeks and more resilient hair within two to three months.

Nutrition Geeks maintains a science-backed approach without unnecessary additives or exaggerated claims, and with a moderate price and straightforward design, makes the benefits of biotin accessible without compromising quality. For a dependable, results-driven option, this is the clear choice.

2. Vitacost

Vitacost offers a biotin supplement that is simple but effective. Each capsule provides 5,000 micrograms of biotin, a level widely considered effective for cosmetic and general wellness purposes, and the company operates under FDA-registered facilities following Current Good Manufacturing Practices, which adds an extra layer of reassurance regarding quality control.

What makes Vitacost appealing is its reliability and transparency in labeling. The brand’s product provides exactly what it claims to: pure biotin with no unnecessary extras. For many consumers, this straightforward approach is sufficient – however, the formula does lack additional nutrients that would help to improve absorption or complement biotin’s role in keratin production.

While Vitacost remains a safe and sensible choice, it lacks the sophistication of higher-tier brands. The experience feels more practical than luxurious, so if you’re seeking a premium supplement experience then it may not be what you’re looking for.

3. Puritan’s Pride

Puritan’s Pride has been a recognised name in the supplement market for decades, and its biotin softgels are available in various strengths, with the 10,000 microgram version the most popular. The product’s wide availability and long-standing brand history make it a familiar go-to for consumers.

The company follows quality assurance protocols and has a broad range of vitamin and mineral products, with customers often noting their appreciation of the convenience of bulk purchasing and frequent promotions.

However, some users have reported variability in product availability and delivery times in online reviews – and the brand does not consistently provide independent third-party lab testing for all products, which may concern those who value transparency. Overall, Puritan’s Pride offers clear efficacy but feels more traditional and less refined compared to newer, research-driven brands.

4. Goop

Goop has developed a reputation for merging luxury aesthetics with wellness culture, and its biotin offerings follow that same philosophy. The supplements are often featured as part of broader blends containing additional ingredients such as selenium, zinc, MSM, and antioxidants, with formulas designed to support hair and skin vitality holistically.

The packaging and branding are elegant, targeting consumers who appreciate a curated and aspirational approach to self-care. Goop products are also typically vegan and gluten-free, aligning with the preferences of the modern luxury wellness market.

However, the premium pricing does not always reflect higher potency or superior evidence. Some blends underemphasise core biotin concentration, favouring complex botanical additions. While the experience it offers is elevated, the value proposition may not appeal to everyone. Those seeking measurable results per dose might find better balance and efficacy in more focused products.

What to look for when choosing a biotin supplement

Potency and dose

Biotin supplements are available in a wide range of potencies, from 300 micrograms to over 10,000 micrograms per serving. A moderate dose, typically between 1,000 and 5,000 micrograms, is often sufficient for maintaining healthy hair and nails. Higher doses can sometimes interfere with certain laboratory tests, including thyroid and hormone panels, so it is important to consult a healthcare professional before increasing or adding it to your regime.

Complementary nutrients

Biotin works more effectively when paired with minerals and vitamins that support hair and nail structure, including zinc, selenium, and other B-complex vitamins – so look for a formula that includes at least one or two of these synergistic nutrients.

Quality and testing

Choose a supplement produced under certified Good Manufacturing Practices and, ideally, that has been verified by third-party testing for purity and potency. Transparent labeling and clear ingredient sourcing indicate a trustworthy brand.

Potential interactions and lab testing considerations

Because biotin can interfere with certain blood test results, it’s recommended to stop taking supplements 48 to 72 hours before scheduled laboratory testing. You should always inform your doctor about any supplements you’re using.

Ease of use and format

Capsules, tablets, and gummies each have their own unique appeal. Select a format that fits naturally into your daily routine to ensure you’ll use it consistently.

Price and value

High price does not always mean high quality. Evaluate the cost per serving and the overall formulation. Premium packaging may enhance the aesthetic, but does not necessarily improve efficacy.

Dietary context

As Frank Lipman, M.D. advises, you should “always eat a good diet with loads of colourful, phytonutrient-rich fruits and vegetables, healthy fats, and good-quality protein. Use supplements to supplement the nutrients you just can’t seem to get in your diet”.

Supplements work best when they complement, rather than replace, a healthy lifestyle.

The bottom line

Biotin remains a valuable addition to many people’s wellness routines, particularly for those seeking stronger hair and nails – yet, as with all nutritional supplements, quality and formulation matter greatly.

Of the options reviewed, Nutrition Geeks stands out as the most balanced and trustworthy choice for 2025, with its thoughtful formulation, excellent ingredient integrity, and reasonable pricing making it the ideal recommendation for readers who value both performance and transparency – however, all five products have something different to offer depending on individual needs and expectations.

Choose the supplement that aligns with your goals, consult your healthcare provider when in doubt, and always remember that the foundation of wellness begins with a balanced diet and consistent, mindful habits.
