  • GrassFit™: Proteins obtained from fresh
    milk from grass-fed cows.
  • No artificial sweeteners:
    with Natural Stevia (Tasteva®).
  • Easily to digest as it contains the
    enzyme Lactase.



100% WHEY CLEAN Formula is a unique product, meaning it is not a shake from a standard whey protein concentrate (WPC). It is a product for which we have used the innovative raw material GrassFit™ 80WPC as the sole protein source.

GrassFit™ 80WPC is a protein concentrate derived from the fresh milk of grass-fed cows. This whey protein is characterised by its high solubility, even at acidic (stomach) pH. As a result, it is digested quickly, delivering amino acids into the bloodstream almost immediately so that it can be used by the muscles in the processes of recovery, maintenance or increase of muscle mass.

Why is GrassFit™ 80WPC a unique and very special raw material?

First of all, this whey protein concentrate (or simply whey) is obtained from a micro- and ultra[1]filtration process through membranes, all at low temperature. This is a physical process without chemicals. Furthermore, it is the only whey protein concentrate obtained from fresh milk of grass[1]fed cows, which graze in the open air in the French Alps for up to 10 months a year. This milk is then collected twice a day to keep it fresh. This means that the nutritional profile is very different to conventional whey concentrates; the fatty acid profile changes, naturally increasing the amount of mono- and polyunsaturated fatty acids. This milk collected to make GrassFit™ 80WPC is raw milk, meaning it does not undergo any heat treatment, which allows it to retain all its nutrients and their nutritional benefits intact, including the proteins. The latter do not undergo any denaturation and therefore retain all their essential amino acids in perfect condition, including Lysine, one of the most heat sensitive often used as a quality reference for this type of product. It is for these reasons that 100% Whey Clean contains a high percentage of essential amino acids, including the branched chain amino acids (leucine, isoleucine and valine) known as BCAAs.

No artificial sweeteners or added sugars

We took care to create a product that is as natural and clean as possible, that is why we chose Tasteva® as to give 100% Whey Clean its delicious and sweet taste. It is composed of steviol glycosides extracted directly from the leaves of the Stevia plant (Stevia rebaudiana B.). This is why Tasteva® is natural, unlike other synthetically produced and cheaper chemical sweeteners.

In addition, the extraction method of Tasteva® is done by means of a patented process that uses only water as a solvent, without using solvents such as alcohols (ethanol, methanol or others), acetone, etc. This avoids the bitter aftertaste of other steviol glycosides.

With the enzyme Lactase

In order to achieve a product that is digested very well and that can be taken by the vast majority of people, we have added the enzyme Lactase. This enzyme is responsible for breaking the bond of lactose so that it can be digested properly. As some people are lactose intolerant, although the product contains a small amount per serving (< 1.7g), we preferred to add this enzyme to improve the digestion.

At Weider, in addition to our commitment to innovation, we care about the environment and animal welfare. That’s why we are committed to sustainability and this product is a clear example of that. The cows are fed only grass, without GMOs, and milking is done in a way that does not disturb them too much in their natural habitat.
