Yet according to the company that sells the wheatgrass pills, their stuff is nutritionally superior to the fresh pressed juice. This in turn makes it tough to tell who is right. Personally, I prefer the fresh juice. I normally drink about 4 ounces each morning, which would be equivalent to 28 of their pills. Since I grow it myself, the cost is minimal -- only a few cents per shot, but even if you buy this big bottle of 500 wheatgrass pills, this amount works out to $1.79 for the same amount (28 pills), or 45 cents per shot. Yes, this is still much cheaper than buying shots at the juice bar at $2 a pop, but I guess the real question is whether it is as good for your body. The next time I go for a trip I will try chomping down on wheatgrass pills for a week and report back on the results.
My recommendation: If you have the time and enjoy growing and juicing wheatgrass yourself, do that. If you really don't have any time to juice wheatgrass yourself, or are travelling, wheatgrass or barley grass tablets would be make a fine choice.
