Find capsules by goal

Say what you want help with. The finder shows what the GB register lets any seller claim for it, what the register assessed and refused, and the cheapest capsules per capsule for each ingredient. It quotes; it never advises.

Libido and Bones and Weight

1309 capsules across 46 ingredients

Libido. Almost no ingredient holds an authorised register claim in this area, which is itself useful information: sellers may not claim what is not authorised. What people discuss appears below with its actual register status.

Bones. Ingredients here hold register claims relating to the maintenance of normal bones, quoted exactly on their pages. Weight-bearing exercise and dietary calcium are the foundations, and the Royal Osteoporosis Society is the specialist charity for anything further.

Weight. The register takes a strict line on weight claims, and very little is authorised. This page shows the real status of ingredients people discuss for weight, quoted exactly. The NHS Better Health programme below is the evidence-based starting point.

Nothing here is medical advice. The wording is the GB register's, quoted exactly; whether a product qualifies to use it is the seller's responsibility. Speak to a GP or pharmacist before taking a supplement, especially if you are pregnant, take medicines or have a diagnosed condition. Wording from the GB nutrition and health claims register; mapping reviewed 4 September 2026.
