How prices are compared

We use active, mapped, in-stock retailer offers checked within 24 hours. Where both the product price and delivery charge are known, the delivered total decides the lowest current offer for that product. An offer with unknown delivery cannot outrank one with a complete delivered total.

109 older or unusable in-stock offers are currently excluded. Prices and stock can change after the shown check time, so confirm the final amount at the retailer.

When value metrics are shown

Price per kilogram and cost per 25 g of protein appear only when the required package, serving and nutrition fields have been reviewed and marked as verified. Missing information is left blank rather than estimated from a product name or retailer description.

Whey Protein comparison questions

What is included in this comparison?

The page covers reviewed Whey Protein powders and whey-based blends in the SupplementScout catalogue. Plant, beef, collagen, egg and casein-only products are excluded even if a retailer placed them in a broad protein category.

Are concentrate, isolate and clear whey the same?

They are different product types and formulations. This page groups them as Whey Protein but keeps each canonical product and pack size separate so prices are not compared as if the products were identical.

Does the first product mean the best Whey Protein?

No. The order favours products with more current retailer coverage. SupplementScout does not make a quality or health ranking without evidence that supports it.

Why is a value calculation sometimes missing?

A current price can be valid even when package or nutrition data is incomplete. We still show the retailer comparison but hide any per-kilogram, per-serving or protein calculation that cannot be verified safely.

How often are prices checked?

Only offers checked within the last 24 hours are eligible for this page. Each product shows its latest check time, and stale prices are removed from the current ranking.

We only feature this comparison in search when it includes enough recently checked offers from multiple UK retailers. If coverage is temporarily limited, you can still use the page, but we will not present it as a complete market comparison.
