What can your supplements actually claim?
The Great Britain Nutrition and Health Claims Register is the government list of what may lawfully be said about a food or supplement. Paste in what you take and see exactly where it sits.
259
Claims authorised
2,082
Claims refused
1,031
Ingredients with nothing authorised
Try “supports better sleep”, “reduces stress”, “detoxifies”, or “reduces tiredness”. Only one of those four exists on the register.
The trending shelf, checked
Every ingredient below has been submitted to the register and refused, or never submitted at all. None of them may legally say what they do.
Authorised claims sit almost entirely with vitamins and minerals. Botanicals, mushrooms and newer compounds are bought on their extract and their standardisation instead, which is a different thing to judge them on rather than a lesser one.
We report on ingredients and claims, never on brands. An unauthorised claim does not mean a product is unsafe or wrongly sold. It means the law does not permit that specific thing to be said about it. Source: GB Nutrition and Health Claims Register, 19 May 2026, Open Government Licence v3.0. Not medical advice.
