Get in touch

Corrections come first. If a figure in one of our guides no longer matches the bottle you received, tell us and we will check it against the current label the same week. Everything else, from editorial questions to partnership enquiries, reaches the same inbox.

Where to send what

One inbox, four routes

Corrections

A dose, price, bottle count, or certification in a guide that no longer matches the label. Include the lot or expiry date if you have it and we will check it against the current panel.

Fixed the same week

Reader questions

Anything about how a comparison was built, why a product ranked where it did, or what a figure in a table means. We answer these ourselves, not with a template.

Two business days

Editorial & contributors

Pitches, category suggestions, and enquiries from researchers or coaches who want to contribute. Tell us the category you know and what you would add to it.

One week

Partnerships

Commercial enquiries reach the same inbox and get an honest answer. Nothing purchased here affects a ranking, a score, or a place on a shortlist.

One week

What we cannot do

Please read before contacting us

−We cannot recommend a dose for you personally, or tell you whether a supplement is safe alongside your medication. That is a conversation for your own clinician, who knows your history.
−We cannot arrange returns, refunds, or warranty claims. Those go to the retailer or the manufacturer, and we have no account access with either.
−We cannot add a product to a guide because its brand asked. Products enter a shortlist by clearing the same criteria as everything else, and no placement is for sale.
