Protein is an important macronutrient. There are many protein choices. Grass-fed protein is better! Grass-fed whey protein comes from grass-fed cows. These cows graze fields and eat grass. Grass-fed cows are almost always raised without antibiotics, steroids, or pesticides, all of which have been found to pass down damaging effects to humans with the consumption of cow byproducts. All Muscle Up Bars are made with grass-fed protein.
