Does Vitamin D Make A Difference?
A review (meta-analysis) published in October 2018 in “The Lancet Diabetes and Endocrinology”, of 81 previously published studies found that both high and low dose vitamin D supplementation did not prevent falls or fractures or increase bone density. The majority of reviewed studies included women ages 65 and older that took more than 800 international units of vitamin D per day. Most of the studies were on Vitamin D alone, not in combination with calcium. The authors noted that smaller, shorter duration trials leaned toward finding stronger results from Vitamin D than longer duration, larger trials. The authors of the study believe Vitamin D supplement recommendations for bone health should be updated to reflect recent research findings.
