Mixes in pretty easily - no funky aftertaste
The mix is pretty finely ground and can be mixed in without the aid of a blender, which is nice. The taste is a light and creamy vanilla so it doesn't leave that weird after-taste you get sometimes. I like that it is no carb and low in fat.

do all isopure products contain soy?
A shopper on Feb 25, 2018
BEST ANSWER: Yes; however, Soy Lecithin is a natural and necessary emulsifying substance found in the cells of all living organisms. It is found in many whole foods such as cabbage, cauliflower, chickpeas, nuts, seeds, and eggs among many others. When this seemingly innocuous additive is listed on a food label, it is usually one of the very last ingredients. This means that minute amounts are present.
When you use the word instantized. Is that the same meaning as hydrolyzed and micronized? In other words does the isopure protein instantly reach your muscles or does it take up to 25 min?
A shopper on Jul 21, 2013
BEST ANSWER: The word instantized means to make (foods or other products) available in instant or easily prepared form. It is not the same as hydrolyzed (reacts with water) or micronized (reducing diameter). The protein in this is pure, all impurities have been removed. It enables it to process faster, but not instantly.
