Don’t confuse correlation and causation. Maybe you were going to get better anyway and it just coincided with the supplements. Maybe the second time was something completely different.

I did X and now I feel better is completely meaningless without some quantitative supporting evidence providing a link between the two.

There’s a reason why the double blind trial is the gold standard of medical proof.

You may of course have this evidence, I’m just commenting on what’s written in this comment.
