ISO+ is 4+ Nutrition’s whey isolate-based protein powder that was revamped and relaunched last year with a new probiotic enhanced formula. The product carried over the majority of the flavors from the previous version, including the likes of Vanilla Smooth, Hazelnut, Strawberry Explosion, and the tasty Chocotella.
A year after the relaunch, 4+ Nutrition has introduced another flavor of the probiotic infused ISO+, although it is currently only available for its smaller 900g tub size, not the larger, 2kg. The new addition to the ISO+ menu is a little more on the creative side with Salty Caramel, providing the supplement’s usual 23g of protein per serve.
