Vitamin B7 (Biotin)

Biotin (Vitamin B7) contributes to the maintenance of normal hair and normal skin, alongside a role in normal energy-yielding metabolism and normal functioning of the nervous system — genuine, authorised claims that make it a popular everyday choice.

What's in this range:

  • Standalone biotin — from Lindens and HealthAid, letting you control the exact amount you're taking.
  • Combination hair, skin and nails formulas — such as Vitabiotics' Perfectil range, pairing biotin with other relevant nutrients in one product.

Worth knowing: biotin's authorised claims are about maintaining normal hair and skin, not promoting hair growth or treating hair loss. Our FAQs below cover this distinction and how to choose between standalone and combination formulas.

Frequently Asked Questions


This is worth clarifying honestly, since it's the most common assumption about biotin. Biotin's authorised UK/EU claim is that it contributes to the maintenance of normal hair — this is about supporting your hair's normal condition, not promoting new growth or reversing hair loss caused by other factors (genetics, hormonal changes, or nutrient deficiencies unrelated to biotin). If you have a genuine biotin deficiency, supplementing can help restore normal hair and skin function, but if your hair or skin is otherwise healthy, taking more biotin than you need won't produce additional benefit beyond that normal maintenance role. If you're experiencing noticeable hair thinning or loss, it's worth discussing with your GP to identify the actual cause, rather than assuming biotin alone will resolve it.

This depends on whether you want a targeted, single nutrient or a broader formula. Standalone biotin (Lindens, HealthAid) gives you full control over the exact amount you're taking, and is the more affordable option if biotin specifically is what you're after. Combination formulas like Vitabiotics' Perfectil range pair biotin with other nutrients relevant to hair, skin and nails in one product, which is more convenient if you'd rather not manage several separate supplements. If you already take a general multivitamin, check for biotin overlap before adding a combination formula on top, since doubling up on the same nutrients across products is easy to do without realising.


Biotin is water-soluble, meaning your body doesn't store significant excess amounts, and it's generally considered to have a strong safety profile at typical supplement doses. One practical thing worth knowing: high-dose biotin supplementation can interfere with certain blood test results, particularly thyroid function tests, sometimes causing inaccurate readings. If you're due to have blood tests, it's worth mentioning to your doctor that you're taking a biotin supplement, or pausing it for a few days beforehand if advised. Beyond this specific consideration, biotin doesn't carry significant known interactions with common medications, making it one of the more straightforward additions to a daily routine.

Biotin deficiency is genuinely uncommon in people eating a varied diet, since it's found in a wide range of foods including eggs, nuts and vegetables. Supplementation tends to be more relevant if you have a specific dietary restriction, a digestive condition affecting nutrient absorption, or if you're specifically trying to support normal hair and skin as part of a broader routine, since biotin's authorised claims apply regardless of whether you have an existing deficiency. If you're generally healthy and eating well, biotin supplementation is more about proactive everyday support than filling a likely gap — if you're concerned about a possible deficiency specifically, that's worth raising with your GP.

With 25 products in this range, the honest answer is that most people don't need to compare all of them — they need to know which two or three variables actually matter. Dosage is the first: biotin doesn't have a set Reference Intake in the UK/EU, and most supplements sit anywhere between 50mcg and 10,000mcg, so it's worth checking the label rather than assuming higher is automatically better. Format is the second: standalone biotin capsules or tablets suit anyone who wants a simple, single-nutrient approach, while combination formulas (biotin alongside zinc, selenium, or other skin-and-hair nutrients, such as Perfectil) suit anyone who'd rather cover several bases in one product. Sourcing is the third: if you follow a vegetarian or vegan diet, check the capsule shell and any gelatin-based ingredients, as not every biotin product on the market is suitable. Beyond those three factors, most biotin products are functionally very similar, so it's rarely worth overthinking the bran

Product and price are both 5 star. Courier awful. Tracking less than useless but seriously, these items are fabulous. And this was definitely the best price I’ve seen. I’ll put up with the longer delivery time. It’s not the seller’s fault at all. I’m telling all my T2D friends about these. The only crisp type snack...

Good quality product, higher dha/epa than others, being in a foiled pouch helps keep fresh and doesn't allow light to oxidise as fast as clear packaging. Recommended.
