Why grass-fed whey protein should be your go-to
Just as you may prefer organic over non-organic, you should go for whey protein from grass-fed cows. Why? There are 2 very good reasons for this: the nutritional content and to avoid unwanted "ingredients" such as hormones, antibiotics and pesticides. Our grass-fed whey protein comes from farms where the use of antibiotics, hormones and pesticides is non-existent. Grass-fed protein also contains more omega 3, vitamins and minerals as well as CLA compared to whey protein from cows that are (unnaturally) fed with grain.

Manufactured in a facility that processes milk, egg, gluten, soy, peanuts, nuts, celery, fish and crustacean ingredients.
Mix one scoop (30 g) with 200-300 ml water, milk or your favorite beverage. Suitable for any time of the day. Adjust the flavour intensity by adding more or less liquid.
Simply shake in a shaker and drink, or mix with frozen fruit and peanut butter in a blender. One Whey® is also a lovely companion to oatmeal, yoghurt or cereal milk.
Consume 2-3 grams of protein per kilogram of body weight per day by combining high-protein foods with supplements.
TIP: Combine slow-release protein like One Casein® with One Whey®, which is faster-acting. Have One Whey® at breakfast after an overnight fast for a quick boost in amino acid levels. Take One Casein® before going to bed and in between meals when slow protein absorption is preferable for optimal recovery.
