What happens if you have too much vitamin C everyday?
I have 1 litre of juice that has over 300 mg of vitamin C in it, is this a bad thing?!? Thanks
First off Vitamin C is water soluble and is passed when you urinate so it does not build up in your system. Some people take about 1000 mg a day so don't think 300 mg is bad. Some experts say taking more than 140 mg a day is wasteful. Some that mega dose in the 1000's have had problems with nausea, vomiting, heartburn, and kidney stones.
Even the experts disagree on a recommended daily dose. Up to 2,000 mg seems to be the high end.
Vitamin C is soluble in water meaning that anything more than your body needs, you wee out. So any excess you're consuming will be left as waste product, not doing any harm.
Vitamin C is water soluble so it will be eliminated by the body through the day. As opposed to vit A (oil soluble), Vit C does not build up in your system, so there is no danger; in fact it is a great anti-oxidant and has lots of benefits.
Getting Vit. C from natural sources is also better than taking suppliments so enjoy your juice
Vitamin C is very essential for almost all body processes. It is utilized by many systems. The really good thing about Vitamin C is that it does not build up in the body to toxic levels like some other nutrients such as Vitamins A, D, E and K. Any excess is excreted through urine. It must be replenished often. Your body will dump the extra today and still need more tomorrow.
Your body 'flushes out' Vitamin C because it is water-soluble, while other vitamins are fat-soluble. What that means is that if your body gets more of a vitamin than it needs, it needs somewhere to store the excess.
1) Most people can consume as much as 2000 mg of vitamin C daily.
2) If you consume more than 2000 mg, your urine becomes acidic, you can experience nausea and diarrhea, your antioxidant-prooxidant balance may shift, and if you have thalassemia or hemochromatosis, you can get into iron overload (vitamin C helps you absorb iron).
3) The safety of your juice would depend on whether it was 300 mg/liter or 300 mg per serving and how much vitamin C you are getting from other sources (tablets, fruit, multivitamins, drinks, etc)
I just posted an article on Vitamin C on my hub. I don't know how to direct you there, other than using my name.
To your question: 300mg is child's play. I don't care if it is per Liter or per serving. That is just plain tiny.
The problem with most of us is we have a little bit of knowledge and it is usually from the wrong source. Not the one that may actually have done the testing or experimenting or or or....
There is a branch of medicine called orthomolecular medicine. A well established branch, with enough published material to crush anyone's card house.
For anyone advocting that 2 000mg will cause nausea, all I can say is : did you try it?
I take a minimum of 30 000mg per day and have never had nausea, even at 80 000mg. We are a species that does not make our own Vit. C and consequently, on a GOOD day, need the bare minimum of 20 000mg.
I don't think you could drink enough juice, Sammyfiction.
I heard one incredible fact about vitamin C. We, humans, and maybe two or three other animal species, are the only animals that DO NOT produce our own vitamin C. All other animals internally make their own vitamin C. As the others have said, it would be very hard to build up too much vitamin C in your system because it is constantly being flushed away when we urinate.
Firstly Diamond-inthe Ruff has a very good Hub on Vitamin C.
I take between 1000-2000mg a day with no problem.
Yes we humans do not produce our own Vitamin C, nor do primates, Guinea Pigs,Fruit Bats, and the red vented Bulbul Bird.
Well of Humans it is not entirely true, we have a mutated gene which doesn't control the enzymes and proteins in the production of Vitamin C. However we do spontaneously get it right and produce around 20mg of vitamin C a day.
A chap called Linus Pauling was taking 10g a day. Diarhea is the first symptom of too much Vitamin C
Vitamin C is water soluble, as are the B vitamins. If there is too much in your body, you will get rid of it in your urine. So, taking megadoses does your body no good. You can only absorb a certain amount and no more.
The doses you are taking are way too low to cause symptoms such as nausea or diarrhoea. Since vitamin C is water soluble and is excreted in urine it can make urine acidic. Acidic urine dissolves alkaline calculi (renal stones) but can increase the formation of acidic calculi such as uric acid crystals.
Apart from that, the only risk is excessive absorption of iron which is unlikely to be problematic unless you are on regular blood trasfusions (e.g. - thalassaemia major / intermedia) or you have at least a family history of haemochromatosis.
On the other hand the benefits of taking vitamin C at this dose is more than the risks as mentioned in other answers.
