I've been trying to increase my iron intake and saw on a 12 oz. can of carrot juice that it contained 90% RDI of iron, as well as 50% RDI of vitamin C to help absorb the iron. The only listed ingredient was carrot juice. I haven't yet checked lables of other brands. This one was canned and not all that tasty, but still far better than the awful herbal tonic I've resorted to in the past. I'm sure fresh, or even jarred, is much nicer. Any way, could it really be that simple. Almost all my daily iron from a glass of carrot juice?
