It may cause respiratory complications.
You may not think it, but vitamin D and respiratory issues are connected. In fact, vitamin D deficiency has been linked to an increased risk of upper respiratory tract infections. Inadequate levels have also been associated with asthma-related events. According to a 2014 study that tracked more than 21,000 adults with asthma, those with the condition and a deficiency were 25% more likely to experience an acute asthma attack and more in need of seeing a specialist on a regular basis. If you're prone to respiratory infections or you have asthma, taking a supplement could help you prevent illness and reduce the severity of an asthma attack.

We all know that vitamin D helps prevent a viral infection such as the common cold, however, what likely isn't as obvious is the vitamin's ability to prevent an infection that can occur down south.

Increased risk of preterm birth.
Preterm birth, which is a birth that occurs before the 37th week of pregnancy, could be prevented. A study that examined more than 2,000 pregnant women with higher levels of 25-hydroxy vitamin D (an indicator of our bodies' vitamin D stores) had a lower risk of giving birth prematurely. Researchers theorize that vitamin D could reduce bacterial infection in the placenta, which is what causes preterm birth in some instances.

You may experience an increased risk of heart disease.
Perhaps the most shocking side effect of them all? There may be an association between vitamin D deficiency and heart disease. One study published in 2009 found that participants with very low levels of the vitamin were nearly three times as likely to die of heart failure. What's more? They were also five times as likely to die of sudden cardiac death. However, further evidence is needed to confirm that there's a direct link.
