Myprotein logo

Myprotein Impact Whey is the cost-per-gram benchmark for certified protein powder. Founded in the UK in 2004, the brand ships to the US with USD pricing from domestic fulfilment — and consistently offers the lowest per-serving cost among Informed Sport certified proteins, particularly during their frequent sale events.

Quick summary

Impact Whey Protein is the best-value certified whey concentrate available — lowest cost-per-gram, 50+ flavors, Informed Sport certified. Clear Whey Isolate is a different product worth knowing about. Sells direct only — no physical US retail presence.

  • Impact Whey: 21–23g protein, ≈103 calories per serving — lowest cost-per-gram in the certified category
  • Informed Sport certified across the core range — batch-tested for banned substances
  • 50+ flavors on Impact Whey — the widest range of any major protein brand
  • Clear Whey Isolate mixes to a clear juice-style drink — a different format from milky shakes, not a substitute
  • Direct-to-consumer only — no physical US retail stores; best value during sale events

Myprotein Impact Whey Protein

21–23g protein, ≈103 calories — the value benchmark

The Data

The Pro Tip

Buy the largest tub size available during a sale event — Myprotein’s pricing rewards both quantity and timing simultaneously. The 5.5 lb bag at sale pricing brings the cost per serving to around $1.29, which undercuts most certified alternatives by a meaningful margin. The brand runs promotions at least monthly; if you see full retail pricing, wait for the next sale.

The Honest Critique

Concentrate-based, not isolate-first. Impact Whey uses whey protein concentrate as the primary source — it has slightly more fat and lactose per serving than isolate-primary products like Optimum Nutrition Gold Standard or Isopure Zero Carb. For most people this is nutritionally negligible, but for those managing lactose intolerance or tracking macros very tightly, this distinction matters. The Impact Whey Isolate product addresses this at a higher price point.

Myprotein Impact Whey Isolate

Isolate upgrade for lactose sensitivity and cleaner macros

The Data

The Pro Tip

Impact Whey Isolate at sale pricing is one of the most competitive isolate options in the US market — the price gap between it and Impact Whey concentrate narrows significantly during Myprotein’s main sale events.

The Honest Critique

Fewer flavor options than Impact Whey. The isolate range covers the core flavors but misses many of the 50+ options available on the concentrate product. If flavor variety is part of the reason you’re choosing Myprotein, Impact Whey is the stronger product; the isolate is a functional choice, not a flavor choice.

Myprotein Clear Whey Isolate

20g protein in a clear, fruit-flavored juice-style drink

The Data

The Pro Tip

Mix with ice-cold water and drink immediately. Clear Whey is designed to be consumed like a sports drink — the flavor quality drops noticeably at room temperature. It’s particularly useful in summer training or post-cardio sessions when a cold milky shake is unappealing.

The Honest Critique

Lower protein than Impact Whey at a higher price per gram. 20g protein per serving versus 21–23g for Impact Whey concentrate, at higher cost per gram. Clear Whey earns its place by solving a real problem — light, cold, no milky texture for summer training — but it’s a complement to your main protein powder, not a replacement.

Myprotein Vegan Protein Blend

22–24g plant protein — pea isolate and faba bean blend

The Data

The Pro Tip

The pea + faba bean blend addresses the amino acid gaps of single-source plant proteins — pea protein is lysine-rich but lower in methionine; faba bean balances this. For a plant-based option, the blend approach is more nutritionally complete than single-source pea protein alone.

The Honest Critique

Texture is noticeably grainier than whey. Plant protein blends at this price point have improved significantly, but the texture remains slightly gritty compared to whey when mixed with water. Use plant milk rather than water if texture matters to you.

Buyer’s Guide: Is Myprotein Right for You?

1. If cost per gram of protein is the primary factor, Impact Whey is the answer. At sale pricing, it consistently undercuts every other Informed Sport certified whey protein in the US market. If you use protein powder daily, buying a large tub during a Myprotein sale event is one of the most cost-efficient moves in the supplement category.

2. The 50+ flavor range is a genuine differentiator for daily users. Drinking the same protein flavor every day gets old quickly. No other major brand offers the same breadth of flavor options. If you’ve been rotating between two or three flavors from another brand, this alone is a reason to try Myprotein.

3. Clear Whey is a different product, not a marketing gimmick. It solves a real problem: milky protein shakes turn off some people, especially in warm weather or post-cardio. If that describes you, Clear Whey Isolate is worth trying as an alternative format. See our protein shakes guide for how clear whey fits the broader category.

FAQ

Is Myprotein good quality?

Yes. The core range carries Informed Sport certification — batch-tested for banned substances and label accuracy. Impact Whey has been on the market for years with a consistent quality track record.

Does Myprotein ship to the USA?

Yes. Myprotein operates us.myprotein.com with USD pricing and ships from US fulfilment centres. Delivery times are comparable to other online supplement retailers.

Is Impact Whey concentrate or isolate?

Concentrate. Impact Whey uses whey protein concentrate as the primary source. The Impact Whey Isolate product uses whey protein isolate. Both are clearly labelled and available on the Myprotein site.

How does Myprotein compare to Optimum Nutrition?

Myprotein offers lower cost per gram at sale pricing. ON Gold Standard uses isolate as the primary source (concentrate for Myprotein) and has a longer US market track record. Both carry third-party certification. Buy Myprotein for value; buy ON if you specifically want the isolate-primary formula.

When is the best time to buy Myprotein?

During sale events. Black Friday and January sales offer the deepest discounts, but Myprotein runs smaller promotions throughout the year. At full retail, the price advantage over competitors narrows significantly.
