How much Vitamin C, do you take? Also is Time-release vitamin C better?

... unless you take esterized vitamin C. I started to take it /because/ of adverse stomache-ache type reactions from 4g of normal vitamin-C, as Ester-C is "buffered". For good and bad, Ester-C is not flushed out like normal vitamin-C, so one does have to be careful of dosage. In both cases, I took C with added "bioflavanoids", as C is nearly useless to the body without the chemicals that comprise citrus flavanoids.

What adverse conditions? Linus Pauling took 12g, lots of people follow him and do the same. It's not a megadose because it's water-soluble and you have to eat WAY more of it to die.

I read this too, in multiple locations (about taking vit. C to counteract the bacon), as I was researching if our daily intake of 3-5 strips of bacon was hazardous. No medical journals/studies, though, mostly paleo-type and "health" websites.

Just to be clear, 2g/day is definitely a "megadose", albeit on the lowest end.

That's interesting. I've never met anyone that megadoses beyond 3g a day. 2-4g a day seems to be where adverse conditions start for most. 2g/day is definitely not "a little" vitamin C. YMMV, of course.

3 large oranges a day usually works out well.

Hi, Jim. I take 500mg per day during allergy season, or if I eat more than a slice or two of beef bacon in one day. (Vitamin C to counteract the nitrates.)

I don't eat much plant matter, otherwise, I might not bother with the Vit. C.

ETA: Dr. Richard Bernstein's new edition of The Diabetes Solution, has some cautions about taking Vitamin C.

Page 57, second paragraph, regarding HgbA1c tests: ...High doses of vitamins C and E can cause deceptive lowering....

Page 69, last paragraph: ...In doses above 500mg/day, however, vitamin C supplements can destry the enzymes on blood sugar test strips and can also raise blood sugars. Finally, in lievels higher than about 400mg/day, vitamin C becomes an oxidant rather than an antioxidant and can cause neuropathies. If you are already taking supplemental vitamin C, I urge you to taper it off or lover your does to no more than 250 mg daily. Use only the timed-release form.

Page 85, in Note: Do not expect accurate blood sugars [from glucose meter finger tests] (or HgbA1c) if you have been taking more than 250mg per day of a vitamin C supplement. Readings may be lower than the true values.

Page 173, last paragraph: ...Large doses of vitamin C in excess of 500gm daily may interfere with the chemical reaction on your blood sugar strips. As a result, your blood sugar readings can appear erroneously low. Large doeses of vitamin C can actually raise blood sugar and even impair nerve function....

Although his words are aimed at diabetics, I will now keep my vitamin C intake according to Dr. Bernstein's recommendations. Stable, healthy blood sugar is a very nice thing! :)

We humans have evolved to survive, subsist and even thrive on relatively low vitamin C levels. We don't make our own, but we're fairly unique in our ability to recycle spent ascorbate.

I personally have tried mega-dosing during a cold previously, I actually prefer just downing gallons of OJ instead. I noticed really no difference between mega-dosing and not mega-dosing during a cold. I also like to take vitamin C when I supplement Zinc for increased bioavailability.

I average well over 100% in my diet daily, so I'm not all that concerned.

Gary Taubes, in Good Calories, Bad Calories explains that when the consumption of carbs is very low, there is very little need for any Vitamin C at all. In the presence of carbs, some would be helpful, but as far as needing any outside of diet, I don't particularly think it's necessary.

I megadose 2g of Vitamin C per day. There are varied benefits (and possible issues) with megadosing Vitamin C. The wikipedia article actually summarizes both well: http://en.wikipedia.org/wiki/Vitamin_C_megadosage .

I do use some supplements and vitamins, but Vitamin C is the only one I purposefully take a large amount of. "Your mileage may vary!"

You may or may not be able to find GF time-release C. However, you can always take multiple doses per day (e.g with meals) for the same (purported) benefits.

I usually take 1-2g of vitamin C powder together with 400mg magnesium citrate, 500mg slo-niacin and 50mg 5-htp.

Also, I do use a vitamin C megadosing to fight cold/flu. Managed to end a cold few weeks ago in under 24 hours by taking 2g doses every 30 minutes.

Only when I feel some sort of cold/flu/sinus infection coming on. I woke up Sunday morning after air travel with a blocked and painful sinus. I downed a zinc tab and 500mg C and so far it's been an annoying runny nose but that's about it.

My self-prescribed remedy of Campari and grapefruit juice works well too :-)

I take a daily multivitamin (http://www.nowfoods.com/Supplements/Products-by-Category/Vitamins/Multiple-Vitamins---w-Greens/M003712.htm). Two capsules in the morning and two in the evening. 500mg of C total.

I also take one packet of the original Emergen-C (http://www.emergenc.com/) when I get to work, instead of having daily coffee. It gives me more energy. Plus the added 1000mg of C have made me healthier.
