Whey Cool, a proprietary non-denatured native whey protein concentrate, is produced to maintain the full range of all the fragile immune- boosting and regenerative components naturally present in fresh raw milk and colostrum. The milk harvested for this product comes from cows that graze year- round on pesticide-free and chemical-free natural grass pastures. Milk from grass-fed cows has many times higher levels of CLA and contains a proper balance of essential fatty acids.
