Best Urolithin A Supplement UK
Best Urolithin A Supplement UK
How to choose a urolithin A supplement on the facts a label can show: that it really is urolithin A, how much is in a daily serving, and how pure it is — plus where urolithin A stands as a novel food in Great Britain and the EU. No health claims, no ranking of other brands.
Check it is urolithin A at all.
Urolithin A is a compound gut bacteria make from ellagitannins in foods such as pomegranate and walnuts; the background is on what is urolithin A. When buying, three things matter: that the label lists urolithin A itself rather than a pomegranate extract, the mg per daily serving, and a stated purity. Then check the regulatory position, because in Great Britain urolithin A is not yet an authorised novel food.
Urolithin A is a novel food. In Great Britain it is not yet authorised: the Food Standards Agency application from Amazentis SA (reference RP1777, received 25 October 2022) was first reviewed by the Advisory Committee on Novel Foods and Processes on 24–25 September 2025, which asked the applicant for more information. In the EU, Amazentis applied in 2018 (application NF 2018/0538, for adults aged 18 and over); trade press reported in February 2026 that EFSA had issued a positive safety opinion and that authorisation was under way, but we have not been able to confirm a published EU authorising regulation, so no official daily limit is in force yet. There are no authorised UK or EU health claims for urolithin A.
Reading a urolithin A label.
Urolithin A is a high-value ingredient, and in July 2026 a US federal court issued judgments against online sellers whose products were falsely advertised as containing it. A clear label is your first defence. Use this checklist on any brand; our own standards are on quality & testing.
| Label fact | What a clear label tells you | Why it matters |
|---|---|---|
| Ingredient name | "Urolithin A" in the ingredient list | Pomegranate extract and ellagic acid are precursors; your gut may make little urolithin A from them |
| Dose per serving | mg of urolithin A per daily serving | Trials used 250, 500 and 1000mg a day; a per-capsule figure can hide a multi-capsule serving |
| Purity | A stated purity percentage | Shows how much of the powder is urolithin A rather than other material |
| Form | Synthetic urolithin A, as described in the novel food applications | Urolithin A in supplements is made, not extracted from food |
| Other actives | Every active listed with its own mg figure | A blend makes the urolithin A dose impossible to check |
| Who it is for | Adults only | The EU application covers adults aged 18 and over |
| Regulatory wording | No claim that it is "approved" or "authorised" in GB | It is not yet authorised in Great Britain |
| Claims | No mitochondria, muscle, ageing or disease claims | No authorised claim exists for urolithin A |

What we sell.
First-party disclosure: Vitality Supplements makes and sells supplements, and this guide only ever ranks our own products. We never name or score other brands. We do not sell a urolithin A product, so there is nothing of ours to rank here. We would not launch one in Great Britain until it is an authorised novel food.
We do sell Urolithin B 300mg, 60 capsules. Urolithin B is a different molecule, not a substitute for urolithin A, and no urolithin A study applies to it. What it is: what is urolithin B. For our editorial rules, see editorial standards.
What the trials looked like.
Andreux et al., 2019 (Nature Metabolism 1:595–603): a randomised, double-blind, placebo-controlled trial in about 60 healthy, sedentary older adults, with single doses of 250–2000mg and then 250, 500 or 1000mg a day for 28 days.
Liu et al., 2022 (JAMA Network Open 5(1):e2144279): a randomised, double-blind, placebo-controlled trial in 66 adults aged 65–90, taking 1000mg a day for 4 months.
Singh et al., 2022 (Cell Reports Medicine 3(5):100633): a randomised, double-blind, placebo-controlled trial in 88 healthy, overweight middle-aged adults, taking 500mg or 1000mg a day for 4 months.
We describe these studies by design only and deliberately do not summarise outcomes. All three used the applicant's own urolithin A, and none is a basis for a health claim, of which there are none authorised.
Study doses describe what was tested, not a recommended intake. The authorised daily limit, once set, is the number that will apply to products sold in the UK or EU.
