What is Whey Protein and how is it processed?
Whey is a natural by-product from the cheese-making industry. It’s the liquid that remains when the solids in milk are pressed together to form cheese. This liquid is then filtered and purified into a powder that is high in quality protein but very low in fat. Because of the nature of whey, the purification process is a low-heat, spray-dry method that does not use any solvents.
Simply put, whey protein builds lean body mass by helping to increase your body’s production of muscle protein, which is especially important after intense workouts.*
It appears you have three different types of Whey Protein. What is the difference?
NOW's three different types of whey protein are formulated to provide anyone, from the weekend warrior to the most serious athlete, with a whey that's perfect for their fitness level.
- Our economy formula is predominantly whey concentrate, which has a slightly different nutrient profile than the isolate form (detailed below) and provides about 16-17 grams of protein per serving. It's ideal for the casual fitness enthusiast.
- Our premium blend contains a mixture of whey concentrates and whey isolates, with higher levels of whey isolate, and more protein per serving (20 grams). For anyone serious about their fitness this is a great choice.
- NOW® Whey Protein Isolate yields more protein with less fat and carbohydrates than concentrates and is considered the highest quality whey protein currently available. Whey isolate has a high concentration of branched-chain amino acids (BCAAs), which aid protein synthesis.* It's naturally low in carbohydrates and contains over 90% protein, compared to 80% for many concentrates and 6.25% for milk. Our Whey Isolates are instantized for easy mixing in milk or water. For athletes on high protein regimens and for those aggressively seeking to build muscle, NOW® Whey Protein Isolate is ideal.*
