Why One Whey®?

The key to reaching your best form? Fast absorbed protein. To reach your fitness goals, you need to consume the right amount of macronutrients, including protein. Our advanced filtration process eliminates unnecessary lactose, fat and carbohydrates to create a high quality whey protein in its absolute purest form. One Whey® is absorbed faster by the body than regular food and also contains extra L-leucine, an amino acid that helps stimulate protein synthesis, supports healthy muscle growth and can help with weight loss.

Unmatched taste

Since its inception, One Whey®’s exquisite flavours have made the product the most sold and loved product in our range. Try Cappuccino to take your morning coffee to the next level, use Vanilla Wildberry as your recovery drink after a workout, or add a scoop of Dark Chocolate to Greek yogurt for a protein-rich breakfast.

Combine slow protein such as One Casein® with faster protein such as One Whey® throughout the day for maximum effect.

Support your active lifestyle

Train hard and recover quickly. Add a scoop to your porridge in the morning, the combination of complex carbohydrates and protein will keep you full until lunch. When you are finished with your gym session, mix One Whey® in your Fitnessguru shaker with water or milk. Our fast-dissolving powder enables you to start the recovery process before you even leave the gym.
