About Vitamins.co.nz Optimum Nutrition Casein

We live in a world where 'fast' isn't just a way of life, but THE way of life. But when it comes to the human body, fast isn't always best.

Casein protein illustrates this perfectly. While fast-releasing protein is great for post-workout, it's not so great for the rest of the day. That's where casein protein comes in. ON 100% Casein Protein utilizes micellar casein, a powerful form of protein that digests slowly and releases over several hours.

Whey rejuvenates your muscles immediately following exercise, but casein fights catabolism for hours and hours. ON 100% Casein Protein is the perfect option for muscle preservation throughout the day.


Vitamins.co.nz Optimum Nutrition Casein Recommended Use

Mix one scoop of 100% Casein with 10-12 ounces of your favorite beverage. For a complete blend, use a shaker. Casein works best away from exercise - right before bed, for example.
