Not all protein is created equal. ProHD uses 100% grass-fed WPI90—a highly pure form of whey isolate with over 90% protein by weight. This makes it easier to digest, lower in lactose, and more bioavailable. If you want to check the quality of your protein: Look at the scoop size vs. protein per serving. A 31g scoop with 26g of protein = ~84% actual protein content. Higher % = less filler, better quality. Some cheaper proteins may look similar on the label, but contain more additives, less usable protein, and lower absorption. Know what you’re putting in your body.
