Tying this to APOE, specifically e4 which has an increased requirement for choline and when choline levels are low there can be a metabolic push that leads to elevated PHGDH activity and consequently, increased serine synthesis. That is a neat connection and maybe why when we study choline supplements we see positive results.

That is super interesting, as is the relationship between choline and sleep. With restorative sleep function, and specifically slow-wave activity, considered to be a significant driver of AD.

> In conclusion, our findings suggest that moderate dietary choline intake, ranging from 332.89 mg/d to 353.93 mg/d, is associated with lower odds of dementia and better cognitive performance.

Gemini tells me that amounts to ~850mg of alpha GPC or ~1900mg of citicoline. Eggs it is then.
