Alfalfa is one of the most mineral-rich plants known. This super food is high in chlorophyll, vitamins A, D, B6, E, K, calcium and phosphorus. It is also rich in phytoestrogens and contains the eight essential amino acids. Because the minerals are in a balanced natural form, they are easily absorbed by the body. If you are looking for an alternative to a mineral supplement, alfalfa is a great choice.
