NAC protects from lung emphysema but induces lung adenocarcinoma in mice
There is mounting evidence that anti-oxidant supplements are cancer promoting (or perhaps more accurately, ‘deprotecting’). A lot of this data is in animal models, but there is also a bit of high quality controlled trial data. The best example is probably that vitamin E increases the risk of prostate cancer (<a href="https:&#x2F;&#x2F;jamanetwork.com&#x2F;journals&#x2F;jama&#x2F;fullarticle&#x2F;1104493" rel="nofollow">https:&#x2F;&#x2F;jamanetwork.com&#x2F;journals&#x2F;jama&#x2F;fullarticle&#x2F;1104493</a>).<p>Proponents will argue endlessly that it isn’t the right formulation of vitamin E and nitpick trial flaws, but taken as a whole the data is pretty clear. Eating AO rich foods is fine, but I would not take a supplement.
