What we have so far
A 2023 Science paper had it falling with age and extending life in mice when replaced. It is also in every energy drink, which is not the same evidence.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
