Educate me on the various methods of administering vitamin C please

I've just learned about "liposomal" vitamin C and how to make it at home 'on the cheap', then I saw this video:

which introduces this new thing I haven't heard of "RHAA" involving zucchini and he also mentions "oxidized" vitamin C THEN I read somewhere about vitamin C enemas!

I'm still researching but I was about to get going on the DIY liposomal thing but I want to make sure I go the best route. I guess I'm looking for the highest absorbing/most effective method. I'm hearing a lot it tastes bad. Maybe the enema method would be a good alternative, and maybe less prep(?). Who's done the RHAA thing? Haven't found any info on that but a couple vids from the same guy above.

What info/opinions you guys/gals have? Tweet
