Summary
Positives
- Patients who feel helped by vitamin D usually start with a clearly low lab value and describe the supplement as correcting a deficiency rather than treating Long COVID in the abstract. Reddit.
Negatives
- Some patients say normalizing vitamin D did not normalize Long COVID, and some feel distinctly worse on aggressive high-dose experiments. Phoenix Rising.
Hurdles & Side Effects
- The practical work is testing first, re-testing later, and thinking about cofactors such as magnesium or K2 before escalating the dose. Reddit.
