Can vitamin D and calcium help reduce your risk of a stress fracture?

Frequency of stress fractures

Stress fractures and musculoskeletal injuries are among the leading causes of medical holdovers that occur during basic military training. As many as 5% of male and 20% of female basic trainees may develop some sort of a stress fracture during military training due to the unaccustomed physical demands and repeated stress to the body, such as marching with body armor and/or a heavy ruck-sack.  A less than ideal physical fitness level and/or being overweight or underweight upon entry into the military further compounds the risk for developing a stress fracture.

Long term effects of these injuries

These injuries may not only threaten your ability to continue to serve our country, but they may also jeopardize our overall military readiness. Many trainees get discouraged after a stress fracture because they have to repeat the training once they've healed or they have to separate from the military. In addition, musculoskeletal injuries sustained during basic training or even in day-to-day military operations can contribute to joint or mobility issues (arthritis) later on in your career.

What can you do?

Optimizing your bone health is essential to maintaining your fitness and readiness.  Along with proper exercise and training, your dietary intake of vitamin D and calcium may play a role in helping you build and maintain strong bones.  Recent studies have linked vitamin D and calcium to bone health and the prevention of stress fractures in military personnel.  However, more conclusive evidence is needed to determine whether universal recommendations regarding vitamin D and calcium are warranted in military personnel (especially basic trainees).  Currently, the Recommended Dietary Allowance (RDA) for both vitamin D and calcium depends upon your age NOT your profession.

Nutritional biochemists and scientists from the U.S. Army Research Institute of Environmental Medicine (USARIEM) are currently conducting research to determine whether increased vitamin D and calcium intake can improve bone health during military training.  Check out more information on this study.

Get the vitamin D and calcium your body needs

Eating a wholesome diet that includes adequate amounts of calcium and vitamin D is your first line of defense in meeting your calcium and vitamin D requirements.  Check out the handy reference below for specific ways on how you can get enough vitamin D and calcium.
