It tastes better than anything else. And it has a lot of vitamins, but at long as you're taking a multi-vitamin who cares. It doesn't have whey isolate so it's really not a good source of whey. It's a great source of cassein and "good" fats, so it's perfect to take a few hours after your workout or before bed for anti-catabolic effects.
For whey you need some whey isolate like Dymatize, ON Gold Standard, or Isopure.
