> unquantifiable "advices" like don't be extreme or that of moderation are best to left unsaid

That wasn't meant to be advice, just my general, nonprofessional, take on nutrition recommendation until I am convinced otherwise. Which I gladly am, because I find human biology (esp. the metabolism) more and more interesting the more I know about it.

I only remember reading that vitamin c in its ascorbic acid form is the predominant way it is transported into the cells (by SVCT1,2 pathways) and DHA transports contribute only a way minor amount.

Interesting, I'll try to find some reading material about that.




DHA is valuable transport since it doesn't require prerequisites and is ubiquitous, also SVCT doesn't transport DHA which you have tones of given that C is among other things ROS scavenger. Can't remember now the details, but I remember reading a paper where it was determined that DHA transport is substantial. Logically fallows that if you have to recycle C, its all you got, since you can't produce C.

Regarding immunity claim, here is something to get you started (50% claim):

> Oral 100-g portions of carbohydrate from glucose, fructose, sucrose, honey, or orange juice all significantly decreased the capacity of neutrophils to engulf bacteria as measured by the slide technique.

We also know what diabetes does to immunity...
