According to a chemical analysis of Tropical Health Foods carao, the iron content is only 14 ppm. That means there should be only 7.25 milligrams of iron in the entire 365 ml (518 g) bottle. Now, the U.S. recommended "daily value" (DV) for iron is 18 mg.  Therefore, you would have to take over 2 full large bottles of Tropical Health Foods carao to get the 18 gram "daily value" of iron. In sum, the carao product is indeed very low in iron.  Its benefit in iron-deficiency anemia appears to not be related directly to its iron content, but rather to some other factor affecting blood generation or iron metabolism.
