Nutravita Biotin Review: A Vegan Hair Supplement Worth It?

Nutravita Biotin is a popular UK-made supplement that delivers 10,000mcg of biotin with coconut oil in a full year's supply. It is cheap per day, it is fully vegan, and Nutravita is a well-established British brand. The honest verdict is that it is a well-made, well-priced biotin tablet, but that biotin itself does far less for hair than the category's marketing implies unless you are actually deficient.

About Nutravita

Nutravita is a UK-based company that has been producing and selling vitamins and supplements since 2014. They pride themselves on using high-quality ingredients across their range, while keeping the manufacturing process free from contaminants.

Not all of their products are 100% vegan, but they are working towards that goal, and the majority are free from the most common allergens. The company has grown quickly to become one of the leading names in pure, high-quality supplements at an affordable price.

This particular biotin supplement built up a large and strongly positive base of reviews on Amazon UK over the years it was on sale. Worth remembering, though, that hair and nails change with the seasons, diet, stress and age, so a wall of happy reviews for any hair supplement is weaker evidence than it looks. That is exactly why we lean on the published research below rather than on the star rating.

What Nutravita claim

• One bottle provides a full year's supply of tablets.
• Biotin contributes to the maintenance of normal hair and skin.
• Enriched with coconut oil.
• 100% vegan and free from gluten, lactose, nuts and soya.
• Biotin contributes to normal psychological function.
• Biotin contributes to normal energy-yielding metabolism.
• Certified and made in the UK under British guidelines.

The hair, skin, psychological function and metabolism claims are the standard authorised wording for biotin, and they are accurate as far as they go. What they do not tell you is whether taking more biotin does anything for someone who is already getting enough, which is the question that actually matters. More on that below.

Ingredients and nutrition

Nutravita's High Strength Biotin with Coconut contains just two active ingredients: biotin and coconut oil.

Per tablet (one a day) your body receives 10,000mcg of biotin, which is 10mg. That is not a modest top-up: it is a very large dose of a vitamin the body needs in tiny amounts. For context, the NHS advises that you should be able to get all the biotin you need from a varied and balanced diet, that biotin is also made by the bacteria in your own bowel, and that taking 0.9mg or less a day in supplements is unlikely to cause any harm. This tablet is more than eleven times that 0.9mg figure. The NHS is explicit that there is not enough evidence to know the effects of high daily doses, and that taking too much might be harmful.

Each tablet also contains 5mg of coconut oil. Nutravita present this as an absorption aid, though biotin is water-soluble, so it is not obvious what 5mg of coconut oil adds.

To form the tablet, Nutravita adds bulking and anti-caking agents. The bulking agents are plant-derived, used to hold the mixture together, while the anti-caking agents stop the ingredients sticking together. Both are vegan.

Does biotin actually do anything for hair?

This is the part most biotin reviews skip, so let's be straight about it.

Biotin genuinely does contribute to normal hair and skin. That is not in dispute. The question is whether supplementing more of it helps someone who is not deficient, and here the evidence is thin. A review of the published research on biotin for hair loss in Skin Appendage Disorders went through every case report and randomised trial it could find. It found 18 reported cases of biotin improving hair or nails, and in every single one the person had an underlying condition or a genuine biotin deficiency driving the problem. The authors concluded that despite biotin's popularity as a hair and nail supplement, the research demonstrating its efficacy is limited.

Put simply: if you are actually deficient, correcting that can help, and it can help a lot. If you are not, there is little good evidence that more biotin grows more hair. And since the NHS position is that a varied diet plus your own gut bacteria should cover your biotin needs, most people taking these tablets are in the second group.

That does not make this a bad product. It makes it a product that is very good at delivering something most people do not need. If you have a diagnosed deficiency, or a doctor has told you to supplement, a cheap year's supply of a clean vegan tablet is a sensible way to do it. If you are buying it hoping for thicker hair and you eat a normal diet, manage your expectations.

Do we recommend Nutravita Biotin?

As a biotin tablet, it is a good one. It is cheap per day, it is fully vegan, it is easy to swallow, Nutravita is a well-established British brand, and a year's supply in one bottle is genuinely convenient. If you want biotin, this is a sensible way to buy it.

Whether you want biotin at all is the harder question, and for most people eating a normal, varied diet the honest answer is probably not. The dose is also far above what the NHS considers a level unlikely to cause harm, which is worth weighing before you commit to taking it daily for a year.

It is also, as of July 2026, unavailable. Nutravita still sell biotin on Amazon UK, but the range has moved to formulas built around zinc, selenium and copper rather than coconut oil, so this particular product looks discontinued.
