Whey protein should mean whey protein, and nothing else. No sketchy additives. No dyes. No laundry list of ingredients you can't pronounce. No artificial sweeteners that leave your protein powder tasting disgustingly sweet (or like chemicals). That's why our whey isolate has only one main ingredient, with no added sweeteners (certified grass-fed, lactose-free whey isolate).

Let’s be clear: This is not just a single-ingredient protein... This is the best ingredient protein.

Centenarius Certified Grass-fed Whey Protein Isolate offers the cleanest and purest protein experience. Sourced from pasture-raised, grass-fed animals in the lush fields of Southeast Ireland, this protein powder is processed using an advanced ice-cold cross-flow microfiltration system. This ensures the removal of all fat, carbs, and lactose, leaving you with 27 grams of high-quality protein per serving, without the bloating or discomfort. The protein isolate is unsweetened and free from additives, flavorings, dyes and fillers, making it a versatile option that blends seamlessly into your favorite beverages.

This whey protein isolate is a step above the rest, designed to optimize performance, build lean muscle, enhance recovery, and promote weight loss. Certified free from heavy metals, hormones, and artificial ingredients, it brings unmatched purity and absorption, delivering superior results with every serving. 

For those looking to fuel their workouts and boost their daily protein intake without compromising on quality, Centenarius Whey Protein is your best choice.

Best Whey Protein Isolate on the market. I’ve tried so many health focused protein powders and this is the best. Clean ingredients, no artificial sweeteners is major nowadays.

Best Protein Powder

I love this protein powder. I recover from workouts faster than with others, it’s easy to digest and has no artificial sweeteners, colors or other ingredients you don’t want. It blends very easily and is a very “clean” protein to add to your diet.
