Vitamin A becomes more easily absorbed, utilized and stored in the body in the presence of b>vitamin E.

Vitamin C increases the absorption of iron, and converts iron to its most absorbable form in the body. Vitamin C is involved with other antioxidants, especially Vitamin E, selenium, and beta-carotene.

Vitamin D works synergistically with vitamin K and calcium to increase the amount of bone-friendly osteocalcin and improve bone metabolism in women with osteoporosis*. Vitamin D also increases the active absorption of calcium.

Vitamin E can increase the absorption, utilization and storage of vitamin A and may protect against hypervitaminosis A. When vitamin E is used together with vitamin C, it has the ability to reduce the risk of preeclampsia in high-risk pregnant women*. Some evidence also suggests that vitamin C might help recycle damaged vitamin E alpha-tocopherol to a more useable form in the body. Selenium enhances the antioxidant effects of Vitamin E.

Vitamin K works synergistically with vitamin D and calcium to increase the amount of bone-friendly osteocalcin and improve bone metabolism in women with osteoporosis*.

Iron is more easily absorbed and utilized by the body in the presence of vitamin C. Vitamin C also converts less-absorbable forms of iron to its reduced (ferrous) and best absorbed form.

Copper is better utilized by the body in the presence of vitamin B6, and in fact, a vitamin B6 deficiency will actually inhibit the absorption of copper.

Boron helps to convert vitamin D into a more useable form, and also influences the effects of magnesium and calcium in optimizing bone metabolism and reducing bone loss*.
