Having tried their Goat Milk Protein Powder, I also was able to try some of their dehydrated goat whey. Whey is a by-product of the cheese-making process, essentially the liquid portion of the milk. The healthfulness of it, is that it has a high concentration of various minerals (calcium, phosphorus, magnesium, sodium, potassium), and is alkaline-based (to offset the acid-ness of your body). It is also rich in electrolytes. This is not as good tasting as the goat milk powder, but not bad.
