Rose Hips - Vitamin C significantly enhances the utilisation of iron. With a concentration more than 100 times that of oranges, rose hips are one of nature"s richest sources of vitamin C.Stabilised Rice Bran (SRB) - SRB is one of the richest sources in nature of vitamin E-related compounds including tocopherols and tocotrienols. The inclusion of SRB in this product is primarily to compensate for the oxidising effect that iron has on vitamin E. Although cereal fibres can impair the absorption of various forms of iron, fully-reacted iron bisglycinate (the only form used by TERRANOVA) is not affected in this manner.Green Barley Grass - In addition to its iron content, barley grass is an excellent source of chlorophyll and folic acid (which is needed for haemoglobin formation). Chlorophyll is particularly significant in that it is molecularly identical to haemoglobin, with the exception of the fact that it contains magnesium instead of iron.Acai Berry - Acai berries provide both of the members of the vitamin E family, tocopherols and tocotrienols. As with the stabilised rice bran, acai is included primarily in order to compensate for the oxidising effect of iron on vitamin E.
