• PREMIUM PROTEIN POWDER - Our grass fed whey protein is unflavored and we truly mean it. We don’t add any sugar, sweeteners, preservatives, colors, or flavorings. The lack of a distinct taste makes it ideal for people who don't like flavored protein powders.
• MADE THE RIGHT WAY - Our pure whey protein isolate is made from the milk from grass fed, hormone-free cows raised in New Zealand. Low-temperature drying techniques give it a better taste and texture compared to ordinary whey protein. Because we instantize our protein with sunflower lecithin it’s incredibly easy to mix and you won’t experience clumping in your drinks and recipes.
• 28g PROTEIN - Each serving gives you 28 grams of all natural protein to replenish your body. Support strong muscles and fast recovery from exercise. Whey protein isolate is the perfect pre or post workout booster for your next shake, smoothie, drink, juice, cooking, or baking recipe.
