Impact Whey Isolate – MARS® - 15servings

MARS® Has landed. We teamed up with MARS® so you can rediscover the great taste — and pack that taste into one seriously satisfying shake.

More protein. Refined for purity.

When your training demands more, your protein should too. Serious athletes and dedicated gym-goers don't just need protein — they need the purest, most efficient form of it, with nothing getting in the way of performance or recovery.

Impact Whey Isolate is designed to deliver exactly that. Each serving is packed with up to 23g of fast-absorbing protein, filtered through a precise multi-step process to reduce fat and lactose, preserving every gram of protein quality.

The result is a purer whey isolate — low fat, just 122 calories per serving — so you get more of what matters, and nothing you don't. Tested by experts.

Trusted by millions. When it comes to what you put into your body, trust matters.

Our whey protein is developed alongside our Performance Advisory Board and independently tested by globally recognised certification programmes — Informed Choice for banned substances and Informed Protein for label accuracy. That's quality you can see on the label, and trust in every scoop.

Reliable. Every time.

With the classic MARS® flavour, staying consistent doesn’t feel repetitive. Smooth, easy to mix, and light to drink, it works just as well in a quick shake as it does mixed into smoothies or stirred into oats.

Whether you’re training hard, tracking macros, or keeping your intake consistent, Impact Whey Isolate fits into your routine without slowing you down. ¹ Protein contributes to the growth and maintenance of muscle mass. ² Protein contributes to the maintenance of normal bones.
