Too much Vitamin C?

[Nis1]

I've done some looking into it but I wanted to know if anyone's had any issues with this. It's recommended that don't take in more than 2000 mg of vitamin C a day. Well between my multivitamin, pre workout, and post workout there's my 2000 mg. anyone ever have any problems because of too much Vitamin C?

2g is unlikely to give you diarrhea.

I've used as high as 4-6g with no issues. Being water soluble and in your case it's not all in 1 dose you will be fine.

recommended by who? With vitamin C, unless its time release, it pretty well all is flushed out within 2 hours anyhow. So getting the 2g in isn't bad if it isn't all at the same time.

I also heard something about it not being good for woman that cancer runs their family history to take excessive amounts or much supplemental vitamin c. Not really sure where I heard that but this thread reminded me of it. If anyone has knowledge of this information id like to know more and whether its bs or not.

I read it somewhere before and when I saw that I was taking in 2000 mg of vitamin C in my supplements alone I decided to look into it. I googled it and the 3 different websites I looked at all said that with more than 2000 mg, nausea and diarrhea can occur. Also kidney stones. But I'm not a small person and so I don't think it will effect me like it might someone of small stature.

There was an interesting thread on this a week or two ago. I am having trouble finding it, but I think the consensus was no more than 1g is needed and the more vitamin c is consumed, the less is absorbed. I also think the thread stated not to take it around peri workout.

I could see that taking 2g of vitamin c from ascorbic acid could do that to your stomach taken all at once

I read not to take more than 500mg at a time somewhere, maybe from Coop. Something about the VitC becoming a pro-oxidant instead of antioxidant. Personally I don't take VitC outside my multi.

Too much of anything can cause problems. Vitamin C is water soluable so it only stays in your system for far less than a day.

[Jiigzz]

500mg is enough to reach saturation within the plasma, any excess is expelled from the body. Has a short half-life of only a few hours and so on.
There has been in vitro tests done to show it turns pro-oxidant at higher dosages but IIRC in vivo there was no issue, although taking beyond 500mg in one sitting is pointless.

There hasn't really been any toxicity issues reported aside from diarrhea (hence the 2g per day UL). In most cases, 500mgs is more than enough.

I remember taking several grams a day for weeks and I actually was dropping weight and mass. I know vitamin C is supposed to suppress cortisol to a degree, but I wonder if extreme excess can raise it?? I stopped it and the weight came back.

I would see no correlation between excess vit C and weight loss unless you mean upwards of 2g and had extreme diarrhea

I was at 3g but didn't have diarrhea that I can remember. It's been about 4 years though.

Vitamin c at 3 or 4 grams is perfectly cool. I candidly do not think c is benign at those levels unlike d or d3 which many advocate. C does not turn pro oxidant and c is good for you. I do agree that everyone is different and some can metabolize more than others. This is all the more reason go take as much as possible. C is really good for old geezers like me and perhaps most important after 35.

If you take 500mg in tablet form though, how much is body going to actually absorb?. I've read on here not to take more than 500mg at a time. But how much of that 500mg is going to actually make it into your blood stream?

Depends on you. I think 1 gram at a time is cool to take. C is the one vitamin my anti aging endo truly believed in besides b12 and tocos. C topical is really good for the face also. Haha, most of you guys are to young to care, but it has kept me young looking. Do both topical and 1gram 2 or 3 times a day. Will not hurt matter what your metabolism may be.

Hi mikeg, my wife was diagnosed with breast cancer approx.3 years ago.
She had the full mastectomy and after doing a lot of research we both decided not to go the chemo & radiotherapy route that our specialist wanted.
As soon as she had recovered from the operation she did a full year of high dose intravenous Vitamin C going as high as 80g per sitting, approx. 3 & 4 times per month. All done through a qualified doctor who did regular blood tests to make sure her kidneys stayed within the normal ranges.

So far she has been in remission and excellent health for the last 2 years.
She still has 1 intravenous sitting per month of 60g just for maintenance & peace of mind and she also religiously takes 6g Vit C per day.

We have certainly made some major changes to our diet & lifestyle after all this but who wouldn't.

Not sure if this info is helpful to anyone but just thought I'd share it.

I have heard of people doing this, but never a first hand account, that's awesome!

Just because you take 2G doesn't mean all of it is getting used. That's Not an unheard of dose... esp if your body is deficient. Anyone ever heard of altrient c? liposomal vitamin c?

[ryane87]

My wife got bit by a dog and loaded up on some Vitamin C. 7 or 8 grams at one time, I don't recall. Anyway, it ****ed her up bad. She got really sick for a day or so. Needless to say, she never did that again. haha
