Hair feels a thicker.

My nails have always been the weak point — paper-thin, peel constantly. Took these religiously for about three months. They're harder now. Hair feels a bit thicker too but that might just be wishful thinking on my part.

Great value.

Bought for my wife but I've been taking them too since she rates them. 180 tablets per pot is great value, lasts ages. The zinc and selenium combo with biotin is a sensible formula.

Naveed I. Coventry · 6 April 2026
Highly recommended.

Started these after my hair stylist mentioned biotin. Notice my hair shedding less when I brush. Three tablets a day is a bit of a faff but I take them with breakfast and it's fine. Will keep going.

Cherelle J. Hackney · 2 March 2026
Reasonable product, fair price.

Reasonable product, fair price. Selenium content is a nice bonus, that's not always included in beauty supplements. Took off a star because I find the tablets quite plain looking but that's hardly a real complaint.

Anna K. Cambridge · 21 January 2026
Doing what they say on the tin.

Six month supply for the price is honestly hard to beat. Vegan tablets which matters to me. My nails are noticeably stronger and my skin feels better hydrated. Doing what they say on the tin.

Overall rating: 4.3 / 5 from 12 reviews.

My nails are certainly improving. My hair is getting better as well. Shame skin isn't. Doesn't seem to remove wrinkles, not so far. Will keep using, has definitely got some benefits.

Store owner replied: Hi Lorraine. Thanks for your review. Since you’ve only just started taking the biotin tablets, it’s completely normal not to notice a change straight away. Results can take a little time, especially with hair, skin, and nails, and consistency matters. Thanks - Lisa -ONYX NUTRA™

I’m finding it ok but I’m still waiting for ‘good’ results!!

Biotin Complex+ Zinc & Selenium Complex – High Strength 12,000µg Biotin

Store owner replied: Hi Kerri - Thank you for leaving a review. Results can take a little time and do vary from person to person. Consistency is the key, and many customers find they notice the most benefit after taking it regularly for a few weeks rather than expecting an immediate change. Liam - ONYX NUTRA™
