- Dietary intervention (Introduce leafy greens and polyphenolic food on a regular basis, don’t eat absolute crap. Fairly simple, yet difficult for many people. If she (or you) can’t seem to follow through with what you know you should do, as is the problem with most people, I would suggest two things.
A: Resistant starch, and probiotics. Gut flora has a massive impact on what you want to eat. Experiencing this effect firsthand is quite enlightening.
B: Habit tracking. There are several, but I’d recommend proddy. It’s fairly new from a guy over on r/NonZeroDay, with a surprisingly good UI, and it’s free.

Vitamin D (2k IU, re: reaction times in older women study getting a bit of sun in the summer from 11-1 could help mitigate the potential deleterious effect on reaction time, if the effect is caused by cholecalciferol acting as a partial agonist and competing with calcitriol, which I think is the most likely MoA)

Magnesium

(Last but not least) An air filter. The correlate between PM 2.5 and all cause mortality is surprising to say the least. The great smog of London lasted about 4 days and is estimated to have killed 12,000 People.
I highly recommend this course on the subject, as well as a little study into indoor air pollution, which is usually worse than outdoor air pollution in many regards.
Coursera also has a course on indoor air pollution that I’ll be taking shortly, but I am so far unaware of the quality of the material, the former course however was surprisingly thorough biologically for such a course.
