Vitamin D seems to be the new big thing. I've had multiple friends tell me they were feeling tired, then they were diagnosed with Vitamin D deficiency and started feeling better after taking supplements. We check Vit D levels all the time on patients. I myself have been a believer in the Vit D hype, and even take supplements myself.
But now this review has come out, stating that "Routine vitamin D supplementation does not prolong life, decrease the
incidence of cancer or cardiovascular disease, or decrease fracture
controlled trials of vitamin D supplementation in the treatment of
depression, fatigue, osteoarthritis, and chronic pain show no benefit,
even in persons with low levels at baseline."
Interesting. I have to admit, it gives me pause. Is all the Vit D hype over nothing? Is this like when I used to take zinc when I thought I was getting sick?
