Supplement guides for the UK
The same label data and evidence as the US site, cut for readers in the UK: dose per serving, which products carry an independent third-party certification, and cost per day for comparison. Every buy button opens the product on Amazon.co.uk.
What is UK-specific here, and what is not yet. The guides, doses and testing status apply to
the products wherever they are sold. The prices and cost-per-day figures are from our US catalogue in USD:
use them to compare products with each other, not to budget in pounds. A UK price feed with UK-market products
is the next step for this edition; until then a buy button opens an Amazon.co.uk search for that product, so
a brand not sold in the UK shows you the closest listings instead of a dead page.
