Marketing sells a single quantity that no laboratory test actually measures.
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.
What we are reading
Gathered for the investigation and not yet written up. Each note says what the paper does and does not show.
The counter-example to 'immune boosting'. Cochrane's own conclusion: routine vitamin C supplementation is NOT justified for the general population. What survives is narrower and more interesting — a duration effect, and a real halving of incidence under severe physical stress. The integrative reading is not 'it works', it is 'it works for a specific person in a specific state', which is a different claim from the one on the bottle.
