New Vitamin D Research Challenges Current Deficiency Guidelines
A recent, novel trial forces a re-evaluation of standard Vitamin D advice, suggesting targeted supplementation might reduce future heart attacks in high-risk patients.
Short Summary
- The TARGET-D Trial examined aggressive, individualized Vitamin D dosing in post-heart attack patients, yielding promising (though statistically marginal) results for secondary prevention.
- Prior large trials failed to show benefits of blanket Vitamin D supplementation, leading guidelines to recommend against routine testing for healthy individuals.
- This new nuanced approach suggests that while current guidelines might remain, clinicians should consider personalized Vitamin D testing for specific high-risk groups.
This content reviews the shift from observational studies linking low Vitamin D to disease, through broad clinical trial failures, to the specific methodology and cautious implications of the recent TARGET-D trial concerning cardiovascular events.

I love how after all these years we still don't have this basic stuff figured out. I guess there's no money in finding out if vitamin D is actually good for you.
People have been calling out the fatal flaw in the studies showing no effects for YEARS: that they don't control for levels but rather just administer a blanket dose. Same for Omega-3.
There was a study that showed that high Vitamin D levels was associated with slower growth of prostate cancer.
As a provider, it has been frustrating seeing study after study not managing for a goal vit d level, but rather just giving a random dose for everyone. Finally, a more appropriate study was performed!
i take 50.000 units per day it's been 6 years. my health is tops I look amazing
All 4 studies referenced in the video are linked in the video's description 💊Supplements that Dr Brad takes: https://drstanfield.com/pages/my-supplements 💊MicroVitamin (multivitamin & mineral that I take): https://drstanfield.com/products/microvitamin For extra insights + a free health checklist, sign up here 👉 https://drstanfield.com/pages/sign-up
Been taking 5000 for 20 years got tested for the first time ever just to see. The test range was 35 to95 in the U.S mine was right in the middle at 65 . I very rarely get sick never had covid either am 68.
The more important question is: Why are low quality studies still a thing? Like, at all?
I would think a study of Vit D WITH Vit K2 would be very important, especially in regards to cardiac health.
Love that you always provide the nuance, thank you for providing this valuable information and all the caveats you're aware of!
