Megadoing Vitamin C

If you start hitting more than 5g/day orally, you're going to start having serious gastrointenstinal problems. I personally don't think you can do much for your immune system above 3g/day; I mean, if it's viral, more anti-oxidant protection (up to the point of potentially becoming pro-oxidant) can only do so much. Vitamin C is the bomb and the shiznit, but if you're really sick, you might want to look into remedies above and beyond just ascorbic acid.

If there's a cure for the common cold, let me know!
Seriously though, what are some things you do to prevent sickness? This just started today and I hate being sick, especially when trying to bulk. I did a little more research and it was suggested by someone else on the board to take anywhere from 1-4g every hour!
Regardless, I'm going to be drinking a lot of water and adding a few hours of sleep to my schedule.

5G per day really isn't that much. Most people I know who advocate mega dosing (including myself) will do a gram each hour. Just keep tabs on how you feel from it. If you start to get gassy (ie farting alot) or otherwise have loose stools, you're reaching or have exceed saturation and it's time to adjust

While that is true, I don't think that is what Hypo is inferring to. As we know Doctors don't treat "healthy" people, their goal is to get people back to a "healthy" state, I think Hypo is inferring how to get the best benefits from megadosing Vit C. One of the best benefits of this is cardiovascular health, i.e., the lining of the veins and arteries stay supple and healthy with large doses of Vit C, and I for one take 4gms twice daily when I feel a "bug" coming on along with 2-300mgs Zinc twice daily, I have been cold/flu free for 3+ years since starting this regimen, I need to add that I also wash my hands and use the hand sanitizer stuff many times throughout the day, which definitely helps.jminis said:

When I start to feel a cold coming on I increase the vitamin C dosage to about 2g/day and take a massive dose of 3mg garlic oil capsules. You can also eat a couple of raw cloves too if you can stomach the taste. You stink like hell, but I swear by the stuff. (taking it at night solves half the problem though) It's a pretty strong natural antibiotic. Just make sure you get the kind that is NOT deodorized.

I start megadosing when my immediate family or a large number of coworkers start getting sick. I take 6-8gm/Day, and take zinc and mag nightly. I've missed out on the past three 'epidemics' of colds. The last round got everyone in my family and almost 1/2 of my office, but I remained cold free. When everyone's well, again, I taper back down to 1 gm/Day. I've taken up to 3gm at once with no GI disturbance, but usually stick to 1gm doses.

vitamin c is toxic at prolonged dosage over 3g/day. symptoms of toxicity are nausea, abdominal cramps, diarrhea; headache, fatigue, insomnia, etc.whosyourdaddy02 said:5G per day really isn't that much.

the RDI for vit.c is only 75mg/day...

I'm sure you have citations to bolster such an unusual claim...given that this is counter to EVERYTHING I've read in the last 30 years on the subject - or do you mean cocaine?chasec said:

The RDI for vitamin C (IIRC) is the amount needed to prevent scurvy, plus a slight margin.g4ud1n said:

If anyone finds themselves getting abdominal cramps or diahrrea from their blow, it's definitely time to find a new dealer.BodyWizard said:
On a related note, I think we need to differentiate between "toxic" and "pro-oxidant". Chasec is most definitely correct if he means the latter, but I would contest the former. Ascorbic acid is not going to be toxic to humans taking 3-4g/day (although even still I do think such a high level of consumption is rather unnecessary; 2g/day seems to be about where it's at orally).
And while I'm here: just because Polaquin does something, doesn't mean you should try it at home.

A bit of an update- I'm still taking about a gram an hour and I actually feel a lot better. A little case of the sniffles still remains, but it is a far cry from the congestion, sneezing, couging, etc of last night.
And I remember reading somewhere that IV vitamin C is actually very effective. I'll try to find it when i have some spare time.

Echinanea, Vitamin C, Zinc works pretty well...
Poliquin is surely an interesting fellow. I read articles on his website sometimes.

Study summary from Pubmed:
"High-dose intravenous vitamin C is not associated with an increase of pro-oxidative biomarkers.
Muhlhofer A, Mrosek S, Schlegel B, Trommer W, Rozario F, Bohles H, Schremmer D, Zoller WG, Biesalski HK.
Division of Gastroenterology at Katharinenhospital, Stuttgart, Germany.
OBJECTIVE: High-dose vitamin C therapy might mediate beneficial clinical effects by counteracting reactive oxygen species. However, concerns are raised whether this approach might provoke diametrical (ie pro-oxidative) effects. The objective was to determine ascorbyl free radical (AFR) concentrations and potential variables of pro-oxidative damage. DESIGN: Crossover study; six healthy males received daily infusions of 750 or 7500 mg vitamin C for six consecutive days. Fasting concentrations of vitamin C and AFR were determined daily. On day 1, concentrations of vitamin C and AFR were measured at 0.25, 0.5, 1, 2, 4 and 8 h post infusion. Plasma concentrations of thiobarbituric acid-reactive substances (TBARS), tocopherol and urine concentrations of 8-oxoguanosine were determined on days 1 and 6. RESULTS: Kinetic studies on day 1 showed that concentrations of vitamin C and AFR displayed parallel dose- and time-dependent kinetics and elimination was highly efficient. Vitamin C and AFR fasting concentrations on days 2-6 were slightly above the baseline, suggesting new, stable steady states. TBARS decreased in both groups, whereas tocopherol and 8-oxoguanosine concentrations remained unchanged. CONCLUSION: Kinetics of AFR largely depend on plasma vitamin C concentrations and AFR is eliminated efficiently. Our data do not support induction of pro-oxidative effects in healthy volunteers given intravenous high-dose vitamin C. SPONSORSHIP: Pascoe Pharmazeutische Praparate GmbH, Giessen, Germany.
Publication Types:
Clinical Trial
Randomized Controlled Trial
PMID: 15054428 [PubMed - indexed for MEDLINE]"
This is for IV Vitamin C, but it does say high doses (7.5g IV per day, which would be a lot more orally) don't cause pro-oxidative effects. Or are they talking about something different than we are?

I missed any mention of cocaine use. Although cocaine is clearly a massive stimulant and promotes fat loss...this type of discussion or use will not be tolerated here. If you want to be a junky, go make a commercial about how you never planned to grow up to be one. Anyone suggesting or promoting use of illegal and obviously highly addictive and harmful drugs will be removed from this board.
