The staff is friendly and knowledgeable on the latest research in the field of nutrition. The Queal itself is nice, but a bit sweet for my taste (too much maltodextrin) and it, on some days, can give you gas. For women the 2100 kcal is too much and for a woman on a diet even the Lite version of 1800 kcal is too much. I eat 3/4 of a standard bag, this gives me enough calories, but only 3/4th of all the minerals and vitamins. I would like to see a Lite version for women.
