In bone metabolism, zinc is needed to produce the matrix of collagen protein threads
upon which the 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. Proper calcium absorption also depends on zinc, and a deficiency
prevents full absorption of calcium. It’s essential for bone healing, and
increased amounts are found at the sites of bone repair. Low levels in the body
have been closely linked with osteoporosis.
It’s unfortunate that in the face of declining intake and growing deficiencies
of zinc in the American diet, authorities have seen fit to lower zinc requirements.
Mild — but still clinically significant — zinc deficiency is widespread
and far-reaching in its effects. The 2–3 grams of zinc found in the body act as
a co-factor in over 200 enzymatic reactions that are instrumental in maintaining
not just the health of our bones, but for optimal system-wide functioning.
