This is a garbage analysis that ends up with a plug for vitamins and t-shirts. You don't write off a journal for making mistakes. Retraction is part of the scientific process.
What this YouTuber failed to mention is that there were already a couple of other studies before this one that reached the same conclusion - that there was no evidence of it working for COVID-19, or that it potentially made things worse in the most sick patients. The retraction of a single paper doesn't invalidate the body of evidence (albeit small) provided by other papers prior to it.
