Kid-e-Calc A wonderful natural calcium formula designed to meet children's specific growing needs. Kid-e-Calc is a synergistic blend of the following herbs: Apple Cider Vinegar, Horsetail Grass, Oat straw, and Lobelia in a base of pure vegetable glycerine. The silica in horsetail grass can be converted into calcium in the human body, and the other herbs work in close conjunction with this master calcium herb. We need calcium to build and maintain nerve sheath, vein and artery walls, bone, teeth, etc. The combination in Kid-e-Calc Extract is helpful for cramps, ("Charlie horses"), successful pregnancies, and building as well as maintaining healthy bones, teeth, hair, skin and nails for children and adults. This combination helps supply that calcium.
