Moringa has more iron than spinach. 100g of leaves or pods, or 25g (less than an ounce) of leaf powder could provide all the daily iron needs of an adult, about 10-20mg. Iron is one of those finicky (difficult to please) nutrients that like good company in order to be absorbed and stay in your body.
While many foods contain iron, it is not easily absorbed unless certain nutrients such as vitamin C and others are present.
Zinc supports a healthy immune system, wound healing, normal growth and development during pregnancy, childhood and adolescence. Moringa leaves, pods and seeds contain zinc in amounts similar to those found in beans, while leaf powder has twice as much zinc per the same weight.
Copper plays a role in the synthesis and maintenance of myelin, as substance which insulates nerve cells to ensure proper transmission of nerve impulses, and as a cofactor for processes that neutralize the dangerous free radicals that would otherwise destroy our cells. We would not be able to produce energy without the help of copper and co-helper enzymes. Healthy muscles, including the heart, could not work without copper. Proper skin appearance and properties and bone formation also require copper. One hundred grams of Moringa leaves provide enough copper for the daily allowance in an adult (about 1mg).
Manganese is mostly concentrated in the bones, liver, pancreas and brain. It is a component of several enzymes such as manganese-superoxide dismutase, which prevents tissue damage due to oxidation. Manganese also activates numerous enzymes involved in the digestion and utilization of foods, breakdown o cholesterol, sex hormone production and the function of bones and skin. The estimated adequate dietary intake for manganese is 2-5mg for adults. Moringa has 5mg per 100g leaves or 50g leaf powder, and thus qualifies as an outstanding source of manganese.
Selenium is an essential trace element with powerful antioxidant properties. Medical research has shown that increased selenium intake decreases the risk of many types of cancers including breast, colon, lung and prostate cancers. Selenium also preserves tissue elasticity, slows down the aging of tissues and even helps in the treatment of dandruff. Moringa contains about 8-10mcg per 100g leaf powder.
