Research reveals new clues to the mysteries of long Covid

It's almost impossible to self-detect signs of improvement when the nature of long COVID is so different from one person to the other, and fatigue comes and goes over the course of days or weeks. It's not even placebo, it's just that it comes and goes, so if you are trying out some new thing, you're gonna start when you're feeling the worst, and get better after a few days because you can't get any worse, then after some time it gets bad again, but patients would think it's normal because their body is being accustomed to the new thing, and request to try more of the thing, even if it does nothing.

We need measurable results, and actual clinical studies over long periods of time.

Trying out this kind of supplements based on "Some patients who have taken them have claimed signs of improvement" is like trusting professor Raoult in 2020 and use chloroquine to treat COVID because he's the only one selling hope.
