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.

Blood sugar and Muscles

11 capsules across 7 ingredients

Blood sugar. A small number of ingredients hold authorised register wording about normal blood glucose levels, quoted exactly on their pages; a much larger number of claims about blood sugar were assessed and refused. Nothing here is about treating or preventing diabetes, and anyone managing blood glucose should follow their care team's advice. Diabetes UK is the specialist charity.

Muscles. Ingredients here hold register claims relating to normal muscle function or muscle protein, quoted exactly on their pages. Resistance exercise and overall protein intake are the fundamentals the claims assume; the NHS exercise guidance below is a good 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.
