"When we launched ISO-BRIDGE, it really raised the bar for whey protein in South Africa. And for a long time, that was enough: it gave people something cleaner and better in a market that didn’t have many options.
But the truth is, we’re never going to settle! We want nothing but the best for our Fam, even if it means discontinuing one of our bestselling products and replacing it with another.
That’s why we’ve made the move to Grass Fed whey isolate. It comes from cows raised the way nature intended, grazing on open pastures, and it’s backed by certification that proves the quality and ethics behind it. The result is protein that’s cleaner, lighter and easier to trust."
Pure Irish Pastures. Pure METALAB.
From the lush green fields of Northern Ireland straight to your shaker, METALAB Truly Grass Fed™ Whey Protein Isolate is the cleanest, smoothest protein South Africa has ever seen. We took everything you loved about ISOBRIDGE and made it even better no shortcuts, no compromises, just the good stuff.
