Short answer: if you want a flavour we’ve actually tasted and can still buy today, get Chocolate Smooth — it never foams, it blends with everything, and it tastes like chocolate rather than sweetener. If you want something more interesting, Salted Caramel is the tested wildcard. And if you cook with your protein, Unflavoured remains the most versatile tub MyProtein sells.

This guide has been running since 2018, and the lineup has changed a lot under it. It’s split into two rankings, kept deliberately separate:

  1. Tasted by us — our own taste-test scores, for flavours we’ve actually drunk that are still on sale.
  2. Ranked from reviews — the flavours we haven’t tasted, ordered using MyProtein’s per-flavour review scores and the consensus in customer reviews. Clearly labelled, because we won’t pass off the internet’s verdict as our own.

Plus an honest section on the flavours MyProtein has quietly retired.

Prices and the flavour list below were checked on MyProtein’s UK site on 4 July 2026.

The value picture first

Impact Whey Protein (1kg)Checked 4 July 2026
List price£30.99 (listed as reduced from £32.99)
Protein per serving23g
Cost per serving£1.03
Cost per 100g of protein≈ £4.48
Flavours listed (UK)30+

One habit worth adopting: ignore the “was” price — MyProtein runs promotions near-constantly, so judge everything on the price per 100g of protein you actually pay. Our MyProtein deals page tracks the current codes.

The flavours we’ve tested, ranked

These verdicts come from our own tubs — we’ve been ordering Impact Whey since 2016, and the scores are unchanged from our original taste tests. Only flavours still listed on the UK page in July 2026 appear here, ranked best to worst.

1. Chocolate Smooth — 4/5 Our pick

The reliable one. If you want a protein that won’t foam no matter how violently you shake it, this is it. Blend it with cashew milk, a banana and peanut butter and it’s genuinely good. Not the most exciting chocolate on the list any more (see the licensed newcomers below), but the one we keep coming back to.

2. Salted Caramel — 4/5

Now listed as a “Milkshake” variant in the current lineup. Tastes exactly as the name suggests — slightly salty with a proper caramel finish. Try it blended with ice. Still the best answer to “I’m bored of chocolate and vanilla.” Two 4/5s at the top: Chocolate Smooth takes the spot for reliability, Salted Caramel if you want a bit more character.

3. Strawberry Cream — 3/5

Nicer than a standard strawberry, mixes extremely well, but noticeably sweet — some of us tapped out after a few weeks. A safe pick if you know you’re a strawberry person.

4. Vanilla — 3/5

Tried and tested, does its job, wins no prizes. The right choice if you mostly blend your shakes with fruit and just want a base that behaves.

Special case — Unflavoured (5/5 for versatility): we score it outside the ranking because it isn’t really a shake. Don’t drink it straight; do put it in porridge, pancakes, rice, soups — anything you cook. On that job nothing flavoured competes, which is why it earns our only 5.

Chocolate Peanut Butter (4/5 in our tests) deserves a mention, though it wasn’t on the UK flavour list when we checked in July 2026 — look for it before you plan around it. (MyProtein has also used the name on a nut-butter spread — that review is here.)

Ranked from reviews — flavours we haven’t tasted

We only give a tested score to flavours we’ve drunk. But the 2026 lineup has ballooned to 34 flavours, gone heavily licensed, and we can’t buy them all — so for the rest, here’s the order the evidence supports. Where a flavour has its own product listing (the licensed bars), we use MyProtein’s own on-site star rating and review count; where reviews are pooled into the main product, we rank on the recurring themes in customer feedback. Treat this as the internet’s verdict, not ours. On-site scores checked 4 July 2026.

The licensed bars — each carries its own on-site score:

  1. Mars® — 4.0/5 (18 reviews). The consensus best of the three: authentic chocolate-caramel-malt, a smooth mix, and it sidesteps the peanut problem that reviewers keep flagging on Snickers. The obvious first experiment if you’re a chocolate person.
  2. Snickers Original — 4.1/5 (56 reviews). The largest review base of the trio and a solid score — the chocolate-caramel base lands, but reviewers repeatedly say the peanut note falls flat. Snickers White is the paler, less-reviewed sibling.
  3. Bounty® — 4.5/5 (just 4 reviews — early days). The highest score of the trio but off a tiny sample, so hold it loosely. Reviewers who like coconut call it genuinely “full-on”; if you don’t like Bounty bars, skip it.

Beyond the bars — reviews pooled into the main product, so no standalone score; ranked on recurring sentiment:

  1. Cookies and Cream — the most-praised non-licensed newcomer in customer reviews, repeatedly named a personal favourite for both taste and mixability.
  2. Mocha — polarising. Fans call it café-quality; others report a recent reformulation as a step down, with a strong, almost bitter coffee note. Coffee drinkers only.
  3. Dark Chocolate, Chocolate Brownie, Caramel Sticky Dates, Acai, the Milkshake range (Banana, Chocolate, Chocolate Fudge, Cookie Crumble) and the Natural line (Chocolate, Strawberry, Vanilla) — thinner review signal so far. We’ll rank these individually as scores accumulate or we taste them ourselves.

We’ll promote any of these into the tested list above the moment we’ve put a tub through its paces.

Gone but not forgotten

Four flavours from our original test no longer appear on MyProtein’s UK Impact Whey page as of July 2026:

  • Blueberry (5/5) — our old favourite fruit flavour, no artificial edge to it
  • Rocky Road (5/5) — basically superior chocolate; made protein pancakes taste like waffle cones
  • Chocolate Mint (4/5) — the After Eight of protein powders
  • Blueberry Cheesecake (3/5) — creamier, less sweet Blueberry

Flavour lineups rotate, so if you spot any of these in a clearance or sample sale, our verdicts stand.

How to choose (the 30-second version)

  • Safe and good (tasted by us): Chocolate Smooth
  • Something different (tasted by us): Salted Caramel
  • Best-reviewed newcomer we haven’t tried: Mars® (4.0/5 on-site) — the licensed bar reviewers rate highest
  • You cook with protein: Unflavoured
  • Fruit person: Strawberry Cream — and mourn Blueberry with us
  • Can’t decide: most people end up with two tubs and alternate morning/post-workout

If you’re still weighing up the brand itself, our full MyProtein review covers quality, pricing habits and what still bugs us after eight years — and the MyProtein vs Bulk comparison is the head-to-head most UK buyers actually need. For everything beyond whey, see our top 5 MyProtein supplements.

Frequently asked questions

What's the best MyProtein flavour overall?

Of the flavours we've tasted that are still on sale in July 2026, Chocolate Smooth is the safest great choice — it mixes without foaming and tastes like chocolate rather than chemicals. Salted Caramel is the pick if you want something less obvious. Among the licensed newcomers we haven't tasted, MyProtein's own reviewers rate Mars highest (4.0/5). Our old 5/5 favourites, Blueberry and Rocky Road, no longer appear on the UK flavour list.

How many flavours does Impact Whey come in?

MyProtein's UK product page listed 34 Impact Whey flavours when we checked on 4 July 2026, including licensed collaborations like Mars, Snickers and Bounty alongside the classics and Milkshake and Natural ranges.

Do flavoured versions have worse macros than Unflavoured?

The differences are usually small, but they do vary by flavour. MyProtein publishes per-flavour nutrition on each product page, so check the label for the specific flavour if you're counting closely.

Is Impact Whey good value?

At the July 2026 list price — £30.99 for 1kg, 23g of protein per serving, £1.03 a serving — it works out at roughly £4.48 per 100g of protein. Discount codes routinely cut that further; see our MyProtein deals page before paying list price.
