Vitamin D3: what is known and what is not

The high-dose vitamin D3 regimen is popular among patients, but it came from people's own reports, without a control group. The first placebo-controlled trial (NCT04570475) is under way, no results yet. If you have tried it, tell us: did you test your levels before and after, what changed. High doses only with a doctor and calcium tests. Source: https://clinicaltrials.gov/study/NCT04570475
