"The Linus Pauling Institute found that a 4:1 ratio of bioflavinoids (already present in fruits and vegetables) to vitamin C was the only thing that increased the absorption of synthetic vitamin C supplements."
So that Bioflavonoid added product falls away as a marketing joke if anything..
About the time-release subject, optimizing the absorbtion is getting alot of magnesium and some Lipoic Acid aswell to get the stuff recycled. Still have a read on a posing of Ted Hutchinson that had me thinking, even though I take his statments usually with a grain of salt:
"When we look at vitamin C the half life is measured in minutes. perhaps about 30mins for someone who is about vitamin C replete. If you think about the digestive system the vitamin c from a whole orange will be available over a period of time and not all arrive in one go. I would only ever use a time release form of vitamin C for that reason.
If you take 1000mg and the half life is 30mins how much vitamin c is left in the system after 3hrs or six half lives have passed.
1000 > 500> 250> 125> 62.5 >31>15.5>
I can't see how you can benefit from vitamin C if you don't use a time release form. It simply isn't practicable to keep taking vitamin c tablets throughout the day and night whereas it is possible to obtain 24hr cover using time release forms."
My main thought about time release is that I know myself not to be able to keep taking Vitamin C every 2-3 hours a day, just because the body excretes it that quickly.. I have a pound of AA chrystals and take it mixed in water occasionally with some sodium bicarbonate, but I want to increase the frequency or take the time release
