How is Our Whey...wayy better? Not all Whey types are sourced, harvested, and or integrated the same into products. In addition to there being different types of whey protein, there are also variations in the quality of the whey protein depending on the source of the milk (e.g. grass-fed vs. conventional cows) and the processing methods used. It is important to carefully read labels and choose a whey protein that fits your individual needs and preferences.
