Star rating 3.5/5

A comprehensive blend of nutrients including omega-3 and antioxidants, although there are also bulking agents, talc and colours in the formulation. The pack contains both a tablet and a capsule, and you are instructed to take one of each a day. The tablet is quite large, and the capsule has a stronger smell to it, which may be more problematic for some, but each blister pack comes with the days of the week on the back to help incorporate it into your daily routine.

Is biotin good for skin?

There are limited studies on the benefits of biotin in skin health, unless you happen to have a biotin deficiency. In fact, there is some concern about the levels of high dosing that can be found in some products as high levels of biotin may interfere with thyroid function. A few small studies demonstrate that when people with thin and brittle nails took high doses of biotin it did have a positive effect.

Is biotin good for hair?

Like with skin health, there also appears to be limited scientific evidence about the effectiveness of biotin for hair health, and any beneficial studies appear to be in those who had a biotin deficiency.

How much biotin should I take per day?

There is no recommended daily allowance for biotin in the UK, because there isn’t enough evidence, and the NHS supports that we should be able to get enough from our diet. Their recommendation is to take 0.9mcg or less without any side effects, but there is also some evidence that supports 30mcg a day for adults being safe, and even higher levels have currently not been found to cause toxicity.

How should I take a biotin supplement?

No single nutrient works on its own, so if you are going to take a biotin supplement, look for one that has other vitamins and minerals as well to maximise efficacy. The standard recommendation is to take biotin supplements with food, and plenty of fluid; the time of day is not thought to be important.

What format of biotin is best?

There is some evidence that liposomal formats may provide better nutrient uptake, but as tablets and capsules tend to contain more nutrients, it might be wise to look for one of these rather than a liposomal format which may have fewer nutrients.

What we looked for in biotin supplements

All supplements were tested within the same time period, with observations recorded based on the testing criteria. We included samples from various manufacturers, offering diverse formats such as capsules, tablets, gummies and soluble offerings, with a range of price points to suit different budgets. The key areas we assessed were as follows:

Taste and flavour: is the consuming experience pleasant?

Nutrient profile: how much biotin per daily dose? How does this compare to the NRV?

Additives: does the product contain additives, for example: preservatives, artificial sweeteners or colourings?

Dietary requirements: does the product meet any specific dietary needs– is it vegetarian, vegan?

Value for money: how does it compare to other products on a cost-per-day basis
