True Cost Rankings · 2026
Best Value Supplements UK 2026
The best-value pick in every category, ranked by True Cost: the price of one full, evidence-based effective serving. Cheap means nothing if the dose does not work, so every product here first has to earn a passing Effectiveness Match score.
Winners are the products delivering the most clinical effect per pound across the 21 categories we currently price. Rankings recalculate as prices and the catalogue change, so this page always reflects the current best buy.

How value is judged
Each product earns an Effectiveness Match score (0–100) measuring how closely its active doses match the evidence-based clinical reference for its category. We then rank the products that pass (score 50+) by True Cost — price per full effective serving — so the value winner is the cheapest product that actually works, not the cheapest product full stop.
