Many powders are padded out with worthless filler. Solgar isn't. It's lactose free, micro filtered and Ion exchanged to remove fat. Pricey it may be but it's worth paying a bit more to avoid low-grade whey-which will make you feel lethargic. Not an ideal combination. It also tastes superb and doesn't contain bovine growth hormone from intensively farmed cow's milk. Try Solgar Whey To Go, visit www.solgar.co.uk for more details.
