The recent inclusion of a blood test for Vitamin D, along with a lipid panel, had me wondering about the reason. Then, a day later when the result came back from Labcorp and was designated 'Low' at 22.8 ng/ml I decided to do some research. Even before the Covid pandemic erupted I had been taking 1,000 i.u. each day of Vitamin D - a vitamin that's been found crucial to avoid respiratory issues. So how could this level be "low".
|≥ 20||ng/ ml |
Generally considered adequate for bone and overall health in healthy individuals
So there it is, the reason for the 'low' designation on my blood test for Vitamin D: The Labcorp testers were going by the Endocrine Society level of at least 30 ng/ml needed for adequate health needs. But as Dr. Tello goes on to point out:
So given I am significantly past the NE JM cutoff of 12.5 ng/ml it appears I can regard myself as definitely not Vitamin D deficient as the Labcorp result suggests. Do I therefore hold steady at an intake or 1,000 i.u. a day or raise it? I believe I hold steady. It's also interesting to note the work of Dr. Joel Finkelstein referenced in the same Harvard Blog. He is the Associate Director of the Bone Density Center Center at Massachusetts General Hospital. His research in the field has spanned 3 decades so he's no newbie to the field.
“Vitamin D has been hyped massively. We do not need to be checking the vitamin D levels of most healthy individuals."
Will someone in higher medical authority please relay the message to the Endocrine Society so they lower their vitamin D "healthy" level designations? And while we're at it let's get the word out to the primary physicians who may order needless lab tests as well.
