Yes! Even simple things like does vitamin D help prevent severe covid (many people are vitamin D deficient)? Should I take vitamin C if I get covid?

What happens when we “talk to your doctor”? Many doctors say don’t take Paxlovid and skip the booster.

Vit D was not proven to prevent severe COVID in RCTs. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10027755/

Thanks - does *anything* help prevent severe covid? If so, it would be nice if the CDC could tell us.

I wish scientific studies could produce consistent results! Here's one with a different conclusion:

"In this Danish observational study of 447 COVID-19 patients, we observed that deficient vitamin D levels were associated with an elevated risk of progressing to a more severe COVID-19 outcome."

Well, we have paxlovid and remdesivir for starters. The vaccine also helps as well.

As for the correlation, this is not causation. Based on observational reports from sources, Several RCTs were conducted with the results not supporting the use of Vit D.

One problem with that study is recent work that has effectively questioned just what a “normal” D3/calciferol level really is, and if significant supplementation offered any tangible benefit.

Well, and vitamin D supplementation is inexpensive. Though, YLE posted recently that it is unnecessary. My PCM recommends it for all her patients during Ohio winters.

I had a bit of a chuckle there. My parents grew up in Cleveland and the newspaper would occasionally be 'give your kids cod liver oil!' with the number of days without sun posted as well. Very old school! As for supplements, I get tested and follow the recommendation here, https://www.opss.org/

I was given Cod Liver Oil once a week when I grew up in the north where there was little sun light during the winter. Now I just make my endogenous Vitamin D from sun light exposure. I do not think I will live long enough to get skin cancer from my exposure.
