If your goal is muscle recovery or hitting daily protein targets, this high-purity whey isolate delivers 27g of **protein** per 31g scoop — nearly 87% protein by weight, which means very little filler is left after processing. Each serving puts you in a strong position without added fats, carbs, or sugar.
The unflavored format gives you flexibility to mix it into smoothies, oatmeal, or other foods without competing flavors. You're also getting 120mg of naturally occurring **calcium** and 130mg of **potassium** from the whey itself, though neither amount is meaningful for supplementation purposes.
The main limitation is what's not here. There are no added digestive enzymes, and whey isolate — while lower in lactose than concentrate — can still cause discomfort if you're highly lactose-sensitive. If that applies to you, start with a half scoop to assess tolerance.
