Vega is vegan, so it doesn't have whey/lactose. You could try looking the ingredients up. They carry it at some supermarkets where I am (Superstore -- I'm in Canada) but also all health food stores should stock it. It's kind of pricey but it's a clean product. The vega "one" shakes have vitamins and minerals, fibre, protein and omegas. They also have sport protein which is a more basic protein.
