My mother-in-law is a holistic vegan with raw foods approach. I find her take on diet refreshing and we rarely disagree about anything.

She takes a green powder supplement made from barley GRASS, not barley wheat. I wanted to know if there was anything to this? She and my father-in-law swear by it but is it paleo? And is it worth the money; ie are there any real benifits to taking this as someone who eats grassfed paleo or is it something more suited to vegans as they tend to have nutrient deficiencies?
