I work at a smoothie shop that sells wheat grass(Robeks if you are familiar) and I had to learn this stuff like the back of my hand. Its looked at by some as a magic potion and I agree its a very good nutritional boost to the average person. Its chock full of vitamins and minerals and must be with fiber because youll be in for serious bathroom time if you make this a regular thing. The recommendation was 1-3 oz of pure wheatgrass a day with anything after 4 being a little much on the body. For a morning boost I think its pretty good at first but the effect wears off, and I dont notice any difference know that I eat more vegetables during the day.
