Calcium 

Your body contains more calcium than any other mineral — making up about 2% of your total adult body weight. It’s stored in your bones and teeth, and the skeleton itself is a reserve of calcium. If your body doesn’t get the calcium it needs from food or supplementation, it takes it from the skeleton and weakens your bones.

Magnesium

​​Magnesium assures the strength and firmness of bones and makes teeth harder. It’s one of the key nutrients needed to ensure calcium is both optimally absorbed and best utilized by the body. It’s also necessary for converting vitamin D into its active form. What’s more, magnesium is required for over 300 biochemical reactions in the body.

Zinc

​Zinc helps produce the matrix of collagen protein threads upon which the all-important bone-forming calcium–phosphorus compound is deposited. It’s also necessary for the production of enzymes that degrade and recycle worn-out bits of bone protein. Zinc deficiency is problematic because it prevents full absorption of calcium. Low levels have been closely linked with the development of osteoporosis.

Manganese

​Manganese is often overlooked as an important ingredient in good bone health, and there’s not even an RDA for manganese. However, research shows clearly that manganese is a co-factor in the formation of bone cartilage and bone collagen, as well as in bone mineralization.

Boron

​​The benefits of boron for bone health have only recently been discovered. Your body requires boron for proper metabolism and utilization of various bone-building factors, including calcium, magnesium, vitamin D, estrogen, and perhaps testosterone. Overall studies show boron has a mineral-conserving and estrogen-enhancing effect, especially among women with low magnesium intake.
