“The primary independent variable, vitamin D insufficiency, was defined as total vitamin D concentration (D2 + D3) ≤20 ng/mL.“
Have your levels confirmed to be above 20 ng/mL, and you should likely do better with your nerves.
I still have not forgiven CDC for failing to notify us that we should take more Vitamin D3 in the winter, the further north we live. Also failure to notice that around 2.5 times more dark skinned people were dying of Covid-19 than light skinned people and warning them to have their Vitamin D levels checked. I believe the August/Sept. spurt in Covid cases in southern states is because that is when everyone is staying in the AC and not getting much sun exposure.
As to the value of above the 20 ng/ml reading as being adequate levels, that is the old thinking about Vitamin D as helping prevent poor bone development (Rickets). The new thinking recognizes the importance of Vitamin D levels to support the immune system. The professionals who value this approach (I think endochrinologists) say that 30 ng./ml should be the cutoff between sufficient and insufficient.
Below is an interesting link about recent changes trying to improve the CDC, and proven waste and theft of Covid money. I hope someone will post it as a separate article.

— This past week in healthcare investigations

Regarding my own experience with Vitamin D3, from summer 2020, to Dec. 2021, I had built up my Vitamin D level to optimum with 66 ng/ml as measured by Kaiser Permanente. In the fall of 2022, I had much anxiety with 3 loved ones dealing with cancer illness. I gained weight from 145 lb. to 157 lb. and had a BMI of 27.5. Mid Dec. 2022 I tested insufficient in Vitamin D, but the figure they gave me was not in ng/ml or any other measure I have seen in the literature. Was KP being told to make it hard for us to follow the Vitamin D picture? A week later I read an article posted by ConservativeMind saying that if BMI was above 25, then the Vitamin D rested in the fat rather than circulating in the blood. I immediately went on a diet but became sick with the respiratory illness my partner brought home from babysitting his sick grandson (was it RSV??). We were sick and miserable, and coughing hard and a lot for over 3 months. Late this Sept. partner brought home another illness from babysitting his sick grandson. We have been sick for over a month and only recently has our coughing almost completely healed. He has promised, “no more babysitting until Spring.” My weight is now down to 130 lbs, I have been taking 10,000 IU or 5,000 IU of Vitamin D since January 2023. I wonder what my VItamin D level will be this Dec. annual checkup? I wonder if KP will still be using this weird measure of D levels? I do hope CDC starts to actually pay attention to the importance of nutritional health and immunity.
I have a niece who has breast cancer, and is currently receiving chemotherapy and looking at surgery sometime soon. She may find this info useful.
Thanks for putting it out there.
