Impact Whey Isolate (From Fermentation)

Premium whey isolate. Made differently. Performs the same.

This is whey — just not the way you know it. Every scoop delivers at least 20g of complete, animal-free protein, made using cutting-edge fermentation.

It starts with microflora. Tiny organisms that are programmed with the instructions to make whey protein. They're fed sugar, water, and nutrients inside a fermentation tank. As they grow, they naturally produce a protein that’s molecularly identical to traditional whey. We then filter and purify it into a high-quality powder, add flavour, and it’s good to go.

You get the same benefits as your usual whey, full amino acid profile, great taste, muscle support¹, just animal-free.

Only available in selected flavours. Just look for “From Fermentation” in the dropdown.
