Nutravita Biotin is a popular UK-made hair growth supplement that delivers 10,000mcg of biotin with coconut oil in a full year's supply, and after three months of daily testing our team rates it as an affordable, genuinely effective pick, especially for vegans. Biotin is a B vitamin typically found in high-protein foods, which is why it can be a useful supplement for anyone on a plant-based diet. You can view the current price on Amazon UK here.
Our team bought one bottle of the Nutravita Biotin Hair Growth Supplement 10,000mcg a few months ago and have been taking one tablet a day, as recommended, ever since. Here's our honest verdict so you can make an informed decision before buying.
| Biotin per tablet | 10,000mcg (0.01g) |
|---|---|
| Coconut oil per tablet | 5mg |
| Tablets per bottle | 365 (1 year's supply) |
| Dose | 1 tablet per day |
| Vegan | Yes, 100% |
| Free from | Gluten, lactose, nuts, soya |
| Made in | United Kingdom |
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.
From looking at the reviews on Amazon UK, customers clearly agree. At the time of writing, the Nutravita Biotin supplement has over 2,400 reviews, with more than 70% of them being 5-star. Those are impressive numbers for any hair supplement.
To put these claims to the test, we bought a year's supply and took one tablet a day, as recommended, for several months.
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, or 0.01g. That sounds small, but it's plenty to ensure you're getting enough of this important vitamin into your diet each day. Each tablet also contains 5mg of coconut oil to help your body absorb the biotin.
To form the tablet, Nutravita adds bulking and anti-caking agents. The bulking agents are plant-derived and completely natural, used to hold the mixture together, while the anti-caking agents stop the ingredients sticking together. Both are vegan.
In short
Each Nutravita Biotin tablet packs the right amount of biotin and coconut oil to top up your daily intake, with no added nasties. It's 100% vegan and free from gluten, soya, lactose and nuts.
Several of the team took one tablet a day for a few months to test the supplement's effect on hair and skin quality.
We all found the tablets very easy to swallow with a glass of water, with no funny aftertaste. In fact, no taste at all. At the start of the test we made notes on the coarseness of our hair and our skin quality, focusing mainly on the face and any oiliness or dullness.
After three months of taking the supplement each day with breakfast, every one of us reported a clear improvement in hair and skin quality. Two of us started to notice changes around a month in.
The most noticeable improvement was a reduction in hair dryness. One of our team regularly dyes her hair, which usually leaves it feeling dry. Three months in, she was genuinely happy with the difference. All three of us also felt our nails had become stronger and our skin looked brighter, but our hair was the biggest and most noticeable change.
What changed for us
A clear improvement in hair thickness and a reduction in hair dryness for everyone who took it. Less dramatic, but still noticeable, were stronger fingernails and brighter-looking skin.
Short answer: yes. We'd happily recommend picking up a bottle from Amazon UK.
The longer answer: it's well worth it if you want a noticeable improvement in the quality of your hair, skin and nails, and especially so if you follow a vegan lifestyle, where biotin can be harder to get from food alone. If you're already blessed with thick hair and flawless skin, you probably don't need a biotin supplement at all.
Getting a full year's supply in a single bottle is a big plus, at a price that won't break the bank. The ingredients are high quality and have to pass stringent checks from independent UK testing companies, and because Nutravita is a British brand with UK-based manufacturing, you can be confident the supplement is safe to use.
Biotin is an important B vitamin. When you consume certain nutrients, your body uses biotin to convert them into energy. It also helps to maintain healthy hair, skin and nails.
Yes. Nutravita Biotin is 100% vegan and free from gluten, lactose, nuts and soya, which makes it a useful supplement for anyone following a plant-based diet where biotin can be harder to come by.
One bottle contains 365 tablets, a full year's supply at the recommended dose of one tablet a day. That makes the cost per day very low compared with many other biotin supplements.
Each tablet provides 10,000mcg (0.01g) of biotin plus 5mg of coconut oil to aid absorption. That's plenty to top up your daily intake of this important vitamin.
