How Our Protein Price Tracker Works
Every price on WheyWise is scraped from the retailer’s own product page and stored with the moment it was read. A change here means we recorded one price, then later recorded a different one for the same product at the same retailer. We compare a product against itself over time rather than against whichever shop happened to be cheapest, because that would measure our scrape schedule instead of the price.
We deliberately do not say “this month”. Retailers are re-checked weekly to monthly, so the gap between the two readings on a card varies from one product to the next. That is why both dates are printed: the card tells you what we saw and when, and you can judge how current it is.
Prices are shown exactly as the retailer listed them, with no voucher-code maths and no estimated discounts. Some links earn WheyWise a commission, which never affects what appears here.
Frequently Asked Questions
How do you track protein powder price trends?
We scrape each retailer's own product page and store every price we read with the moment we read it. When a later reading differs from an earlier one for the same product at the same retailer, that difference is a price trend. We compare a product against itself over time rather than against whichever shop happened to be cheapest that week, because that would measure our scrape schedule instead of the price.
How often are protein powder prices updated?
Retailers are re-checked on a weekly to monthly cycle depending on the source, across 57+ UK retailers. That is why every price on this page carries the date it was checked: the gap between the two readings behind a change varies from one product to the next, so we show both dates rather than claiming a fixed window like "this month".
Which protein powders does the price tracker cover?
Whey protein concentrate, whey protein isolate, clear whey, casein, mass gainers and vegan protein powders, from the brands we hold a catalogue for. A product appears here only once we have recorded at least two different prices for it, so newly added products take a few scrape cycles to show a trend.
Why has a protein powder price gone up?
We report what we measured, not why. Rises are usually a promotion ending, a pack size changing, or a retailer moving off a launch price. Because both the old and new price are shown with their dates, you can see whether a rise is a return to a normal price or a genuine increase.
Are these the cheapest protein powder prices in the UK?
Not necessarily. This page ranks by how much a price moved, not by how low it is, so a big saving on an expensive tub can still cost more than a product that never changed. To find the lowest price per 25g of protein, use the comparison table instead.
Do discount codes affect the prices shown?
No. Prices are exactly as the retailer listed them, with no voucher-code maths and no estimated basket discounts, because a price you cannot reliably obtain is not a price. Some outbound links earn WheyWise a commission, which never affects what appears here or in what order.
