Zinc is good for fighting colds and building bone

Are you hearing more coughs and sneezes now than you did during the dead of winter? I’m not surprised, given that the change of season can up your chances of catching a cold.

When I feel the sniffles coming on, I load up on zinc. It’s been shown to help to shorten the length of a cold when taken at high doses within 24 hours of exposure to a cold.

This is yet another example of how everything you do for your bones is good for your body, as zinc is one of the key minerals for bone health.

The latest research about zinc

Researchers are constantly adding to the knowledge about the bone benefits of zinc. Most recently, a study in Iran showed that postmenopausal women with osteopenia or osteoporosis had significantly lower than normal levels of dietary intake of zinc as well as calcium and magnesium. On the basis of their results and previously published studies, the researchers suggest “mineral supplementation especially with calcium, magnesium, zinc and perhaps copper may have beneficial effect on bone density in post-menopausal women with low bone density.”

Are you getting enough zinc?

The average person in the U.S. takes in about 46–63% of the recommended daily allowance of zinc. That’s 8 mg a day a day (which is the amount found in Better Bones Basics). The common therapeutic range for bone health for the same woman is 12-30 mg a day (with my Better Bones Builder containing 25 mg). And in case you’re wondering how much zinc you need to fight off a cold, zinc lozenges with a dose of 75 mg showed benefits!
