Health secrets of silicon: why this mineral is an ally for baby boomers.(SUPPLEMENTS: CLOSE UP)

Imagine being able to reduce fine lines and wrinkles, while renewing dull, dry hair and brittle nails, all with one supplement. Not only that, the same nutrient strengthens bones, encourages healthy joints, keeps blood vessels smooth and elastic and reduces the risk of Alzheimer's disease. No, it's not something from the Fountain of Youth. It's silicon, a trace mineral that has solid scientific support behind its long list of benefits.

If you haven't heard of silicon, you're not alone. After a flurry of scientific interest in the 1970s, silicon was off the radar screen until recently. Many people are unaware that it is an essential nutrient.

From the Inside Out

Silicon's status as a well-kept secret is likely to change soon. Research shows that silicon can have an effect on issues that matter to the baby boomer generation. When it comes to reducing wrinkles, for example, silicon accomplishes what no cosmetic cream can--it works from inside the body to enhance production of collagen, the protein that supports the outer layer of skin. In fact, a 2005 study of 50 women found that those who were given 10mg of silicon supplements daily for five months experienced improvement in shallow wrinkles, along with greater elasticity of their skin. There was also a significant reduction in brittleness of nails and hair. The women in the placebo group did not experience any of these improvements.

But silicon's collagen-promoting advan rages are more than skin deep. Joints also require healthy collagen production to function properly and perform necessary repair chores. Without it, the cartilage and connective tissue in joints can't maintain the "cushions" that keep bones from making contact. Result: the pain, swelling and difficulty moving that characterize osteoarthritis.
