You can get a better explanation from the company we are talking about, but I will try my best to describe it.
Whey is a byproduct of dairy products, it is then refined and makes an excellent protein source! Whey protein Concentrate is the cheaper of the whey, as it still contains some lactose, but is still a good choice and cheap.
Whey Protein Isolate is more expensive as the process takes more to get the lactose completely out. This is a better choice if you are lactose intolerant! It's a little more pricey, but well worth it.
What I do is combine them to make it decent price wise and taste wise. If you ever get a chance Taurus check out their website and maybe order a couple of pounds to see if you like it. If you can add a couple of protein shakes to your diet, you will fulfill your protein requirements for the day. Without protein you will be spinning your wheels at the start line!
