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.

Joints and Fertility and Heart

1408 capsules across 64 ingredients

Joints. Joints carry the largest set of refused claims in the register: glucosamine, chondroitin, MSM, turmeric and collagen-for-joints wording were all assessed and turned down. What is authorised is narrow and quoted exactly on the ingredient pages: vitamin C for normal collagen formation for the normal function of cartilage, and manganese for normal formation of connective tissue. Versus Arthritis is the specialist charity for anything beyond nutrition.

Fertility. Ingredients here hold register claims relating to fertility and reproduction, quoted exactly. UK guidance on folic acid before and during early pregnancy is the best-established nutritional advice in this area, and Fertility Network UK below offers wider support.

Heart. This page collects ingredients whose register claims relate to the heart, blood pressure or cholesterol, quoted exactly. Diet, movement and prescribed medication come first in this area, and the British Heart Foundation below is the specialist charity for reliable information.

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.
