I believe there are protein powders you can mix with fruit juices ?
Also it does not have the MOST protein in it ,,, i am not sure if there is any dairy in the mix itself. you might try Carnation instant breakfast mix. Anything "Whey" will have dairy in them . So careful with that. Check out "Celiac Forums" for Celiacs disease . They have to stay away from dairy .
Just did a quick search and found these ..
Protein from Rice, Powder, Dairy Free, Vegetarian / Vegan, Hypo Allergenic, Plain - 1 lb. 5 oz. Go Dairy Free | Beverages - Smoothies & Mixes
If you find a mix you can mix it with Lactose free milk could you not ? Can you drink that ? If you have a whole foods near you they should have tons of info or stuff.
HTH
mindy
PS I just googled " Dairy Free Protein Mix" and came up w/ quite a bit
