Vitamin D: Can You Afford To Be Deficient?

Research continues to show the impact of vitamin D on all aspects of health.

Scientifically reviewed by: Gary Gonzalez, MD, in August 2023. Written by: Chancellor Faloon.

Vitamin D impacts our health from immunity to heart health. Here is an update on some vitamin D studies in recently published articles:

  • Supplementing with vitamin D was associated with a lower rate of rhinovirus infection (the most common virus causing colds) in asthmatic children compared to children who were not supplemented.1
  • Crohn's disease patients had significantly lower vitamin D blood levels than healthy controls.2
  • Tuberculosis patients were twice as likely to have vitamin D deficiency compared to patients without tuberculosis.3
  • Vitamin D deficiency is associated with elevated oxidative stress across multiple age groups.4
  • Patients with benign paroxysmal positional vertigo who received conventional treatment plus vitamin D and calcium supplementation showed a lower rate in the annual recurrence of vertigo attacks compared to those who received conventional treatment only.5
  • Coronary artery bypass patients supplemented with acute dosing of vitamin D (150,000 IU of vitamin D daily for three days) before surgery had significantly lower indicators of heart cell death.6
  • Higher vitamin D blood levels were associated with a better response to the hepatitis B vaccine. However, vitamin D supplementation starting on the third day following vaccination was not associated with a better vaccine response compared to controls.7
  • A review of the scientific literature concluded that there is convincing evidence that vitamin D supplementation is valuable for the treatment and prevention of erectile dysfunction.8
