For Strong Bones, Girls May Need Vitamin D At An Early Age

By , About.com Guide   August 31, 2010

Follow me on:

To build strong bones, girls may need to start taking vitamin D supplements prior to early adolescence. In a recent study of 73 girls (ages 12 to 14), those who received four doses of 150,000 IU of vitamin D over the period of a year showed no significant improvement in bone health. According to the study's authors, this finding suggests that earlier supplementation is needed in order to make the most of peak bone-building years.

Vitamin D is essential for maintaining normal blood levels of calcium and phosphorous, which in turn helps support the hardening of bones. Running low on vitamin D may lead to the development of osteoporosis, a condition marked by decreased bone density.

Although vitamin D is available in some foods (such as certain fish and fortified cereals), it's difficult to get your recommended daily intake solely through dietary sources. Your body can synthesize vitamin D during exposure to the sun's UVB rays, but getting too much sun can raise your risk of skin cancer. Therefore, many medical experts recommend taking a daily supplement in order to boost your levels of vitamin D.

Big deal with your findings! Your body can most likely produce up to 50,000 IUs of vitamin D per day when exposed to summer sunlight. The findings equate to 12 days on the beach in their lifetime. (4 doses of 150K or 12 days of 50K at beach)

Do you think our bodies were created to spend 12 days of our lifetime in the sun? Most people should spend as much time in the sun without sunscreen and without getting burned.
