I am agree on this.

@caerulln

For RDA standard, 1000mg is overdosed. but for ODA, it is not.

ODA?
Never used that standard before.
Which organization set the Optimal Daily Amounts?

RDA is Recommended Daily Amounts

Stone[97] and Pauling[75] calculated, based on the diet of primates[74] (similar to what our common ancestors are likely to have consumed when the gene mutated), that the optimum daily requirement of vitamin C is around 2,300 milligrams for a human requiring 2,500 kcal a day. Pauling also criticized the established RDA as sufficient to prevent scurvy, but not necessarily the dosage for optimal health.[84]

I take it once a day or two days once ..

Why do dogs not having grey hairs ?

One of the reasons I found out is that animals like dogs can produce Vitamin C in their liver.
The amount can go as high as 10g per day produced depending on their stress level and various conditions.
Polar bears although so padded with fat but never got a heart attack. Anyway has anyone seen a dog died of
heart attack ?

Unfortunately for humans and some species of apes and guinea pig somehow lost the ability to produce
vitamin c in their body but has to take in from outside ! a genetic defect indeed !

To most humans 1000mg of ascorbic acid should be ok ! Nothing to be afraid of !

Lol, after reading thru the posts, I find all the regular "nutritional supplement advocate" gang here again.

Some are even trying to say that thier M.B.B.S is a sham. Maybe you guys should build your own "medical school", sorry I meant nutrition school.

Anyway, here's my take. I dunno about Redoxon, and what Bayer does behind everyone's back. But I offer to share some info on Vitamin C.

Vitamin C is an essential vitamin, which means that the body does not produce them. I sure every one knows that already. RDA is the reccomended daily dosage to prevent oneself to be symptom free from vitamin deficiency.

Vitamin C have been shown to be relatively safe in doses up to 10grams. Doses of vitamin c up to 1-2 grams have been shown to reduce incidences of colds, flu, etc, although results are not always consistent. BUt one thing is for sure is that it safe at these dosages. Taking doses above 2-5grams is relatively useless because it is passed out in urine anyway. Also, taking doses at about 2grams does have its side effects which is gastic. Vitamin C is acidic. There have been complains about gastric and gastro intestinal disturbances when taking at these doese and above. There are alternatives of course, such as Sodium Ascorbate which are salt derivatives which are said to cause less gastro-intestinal side effects. However, these derivatives are usually very expensive.

Lastly, I'm sure many people like to BS about your Health vs. Money and how one should take every single vitamin over the RDA and what are you going to save if you don't have your health. I find these statements very irresponsible. Some people may earn RM5k, so they may be able to afford whatever vitamins they want. Some may earn RM2k per household of 5 living in the middle of KL and buying vitamins means they might not have enough food to go around. I'm sure most med school have topics teaching the Doctors about patient quality of life and how to help patients balance between what they can afford to buy for their health according to their finacial capabilities. But not everyone goes through med school, do they?

Edit: BTW, taking doses up to 10grams is safe on a daily basis as long as your stomach can take it.

Dogs & polar bear is a lot different from humans.
& I don't think anyone could know if a dog dies of heart attack or not unless an autopsy is done

RDA for Vitamin C is around 100mg/day, the surplus will be excreted in the urine.

Bt why there is so many 500mg, 1000mg vitamin C in the market?
--> more product for phamaceutical company to sell --> more $$$
--> more u eat --> more they earn

while u wont get 200% healthier by consume those vitamin
As for normal healthy person, natural vitamin from food is more than enough for well being.

and i think i have never see or heard anyone with Vitamin C deficiency in malaysia yet.

I think because the drug companies know that excess vit-c in that amount will just go with the urine without side effects.
& they also know that big numbers sell .
Imagine if they sell 100mg vit-c when their competitors are all selling 1000mg.
Their sale to lay person will be affected.

So they are cheating the consumers =x

Not really cheating.
More to misleading..
As the product does not have side effects, it can continue to be sold in the market.

I think i rather eat a few oranges rather than pills.
More fresh & taste better

gosh, the physician and pharmacist are here again to talk about nutrients that they not really study on

Yeah I think dietitians & those who are studying dietetics should chime in.
You guys are experts in this matter.
We are just lay person trusting whatever info we encounter on the net.

And I'm sure you did

information on the net not everything is 100% true.. wan the more accurate answer proceed to the specialist... ^^

What Poison?.. If you want to take Vitamin C first consult your your doctor?.. or refer to the Pharmacist at the Pharmacy. And make sure sure KKM label is there at the package. No KKM label means the produck os not approved and is not save to consume. Kindly check the KKM label at bottom part of the case 9Redoxon) it stated there KKM20020730X. So what the fuss ?..After all Vit C is not classified as drugs..Take it or leave it..ZAIN.

i know this is an old thread but i just start consuming Redoxon Vita Guard... not the dedicated vitamin C, the one in yellow box (vita guard in red box)
i now don't have morning drippy nose & cold sneezing.

I gent through all the 3 pages... and it seem this one user seem carved on stone that it's dangerous (i assume he/she's talking about the yellow box)

so my questions...

1. did someone here have any experience with the said product (the red box) and has any side effect?

2. what's best way to consume... half a tablet a day, or a tablet every 2 days?

tq

I took last time one tablet 1000mg
Body feel heart feels hot and feverish. Stop taking since then
