Limited Time Access: Dr. Michael Holick Responds to Endocrine Society Guideline Updates

Published on November 21, 2024

Dr. Michael Holick’s review article responding to the latest Endocrine Society update on vitamin D guidelines has now been published! Congratulations Dr. Holick!

In his review, Dr. Holick, who was chairman for the 2011 Endocrine Society’s Guidelines on Vitamin D, offers his perspective on the latest ES Guidelines on Vitamin D.

Although these updated guidelines relied heavily on data from randomized controlled trials (RCTs), there remains an important and irreplaceable role of observational and association studies, data which was ignored for these guidelines. Dr. Holick offers a well-rounded review of such studies and very clearly demonstrates the observed benefits of achieving and maintaining vitamin D levels of at least 30 ng/ml (75 nmol/L), optimally 50 ng/ml (125 nmol/L). Such findings are outlined in Table 1 from the paper, which are illustrated in the chart below showing decreased risk of various clinical outcomes based on achieved vitamin D level.
