Do you lack vitamin D?

If you spend more time indoors and spend less time outdoors, your risk of becoming vitamin D deficient increases.

Research suggests that approximately one billion people worldwide are vitamin D deficient, which can have negative consequences for your health.

Sun exposure is the easiest way to stimulate vitamin D production in your body, making you particularly vulnerable if you do not spend enough time outdoors. To counteract this, you may need to supplement with vitamin D3.
