MyProtein Review (2026): The Bad, The Good and The Great

Short verdict, eight years in: MyProtein is still worth buying — if you buy it right. The products are certified, the range is enormous, and with a discount code the per-protein price is hard to beat. What you’re navigating is the noise around the products: rotating flavours, theatrical “was” prices, and a marketing machine that never sleeps.

We’ve used MyProtein since 2016, and eight years of tubs have settled the shape of this review: the Bad, the Good and the Great. Prices and product details were checked on MyProtein’s UK site on 4 July 2026.

The Bad things about MyProtein

The flavour lottery is real

With 30+ Impact Whey flavours on the UK list, some are inevitably more “miss” than “hit” — we’ve had tubs we loved and tubs we quietly donated. This hasn’t changed in eight years. The fix is simple: don’t gamble a full tub on an unknown. Our tested flavour rankings exist for exactly this reason.

The pricing is theatre

Almost everything on the site shows a “was” price. When we checked in July 2026, Impact Whey Isolate was listed at £44.49 “down from” £58.99 — a discount that, in our years of watching this site, is closer to the permanent state of affairs than a sale. Treat RRPs as decoration. The only number that matters is the price per 100g of protein you actually pay (more on that below), and it should almost always be improved further by a code from our deals page.

The promotional emails

Sign up and your inbox will know about it. There’s a deal most days, which rather proves the point above. Unsubscribe early; check the deals when you want to buy, not when they want to sell.

Small print varies across the range

The catalogue is huge, and bases, sweeteners and allergen profiles differ product to product — don’t assume the label you read on one MyProtein product holds for the next. Thirty seconds on the ingredients tab saves a wasted tub (and if you’re a tested athlete, stick to the certified lines mentioned below).

The Good things about MyProtein

Independent certification, not just marketing

Impact Whey Isolate carries Informed Choice and Informed Protein certification (independent banned-substance and protein-content testing — checked on the product page, July 2026). That’s a meaningful third-party signal, especially if you compete in tested sport.

On MyProtein’s own site, Impact Whey holds a 4.64/5 rating across roughly 30,000 reviews — their data, so read it as directional rather than gospel, but it matches our experience of the core products.

The range really is a one-stop shop

Whey, isolate, clear whey, vegan options, creatine, snacks, clothing — whatever your training looks like, the catalogue covers it. That breadth is genuinely convenient: one basket, one delivery, one loyalty scheme. (It’s also how they get you — see “promotional emails”, above.)

The deals, used correctly

The near-permanent discounting is a flaw when it’s dressed up as urgency, but it’s a feature when you exploit it deliberately: stock up when the code is good, ignore the countdown timers, and never buy at list. We track the current codes on the MyProtein deals page.

The clothing is better than it needs to be

Still decently priced, still fits well, still updated regularly. Not why you’re here, but a legitimate add-on to a supplement order.

The Great thing about MyProtein

Impact Whey Protein, judged by the numbers

The flagship remains the reason the brand works. As of 4 July 2026, the UK page lists a 1kg tub at £30.99 — £1.03 per serving for 23g of protein. That’s ≈£4.48 per 100g of protein at list price, before any code touches it. MyProtein calls it the UK and Europe’s No.1 best-selling whey — their claim, but a believable one.

Here’s how the value maths stacks up across the products people actually cross-shop (all prices as listed on 4 July 2026):

Two honest observations from that table. First, the Isolate premium buys you certification, near-zero fat and 0.5g sugar — worth it for some, not for the average scoop-in-milk user. Second, at list prices, Optimum Nutrition’s Gold Standard actually undercuts Impact Whey per gram of protein — MyProtein’s real advantage is that its codes fire constantly and its flavour list is twice as long.

So — is MyProtein good?

• For beginners: yes. Impact Whey + a flavour from our rankings is the lowest-risk first tub in the UK.
• For budget buyers: yes, with a code. At list price, compare against ON first and check MyProtein vs Bulk.
• For flavour explorers: emphatically yes — nobody else runs 30+ flavours with licensed Mars/Snickers/Bounty collaborations.
• For tested athletes: stick to the certified lines (Impact Whey Isolate’s Informed Choice/Informed Protein marks, verified July 2026).

Round up

Eight years in, the conclusion holds: MyProtein earns its place as our default recommendation, not because it’s flawless but because its flaws are avoidable — buy with a code, buy flavours somebody has actually tasted, and read the label on anything new. Everything great about the brand survives that discipline intact.
