8 Vitamin C Benefits (and Some Common Side Effects)

I too have taken Vitamin C for colds and flu for over 20 years.

I had a friend of mine who got a full body flu...he said he ached from head to toe...he was shivering and sweating a lot and looked very pale. I suggested that Vitamin C might help...to take 500mg every hour (if wake up a night = take another 500mg). He took the C with a little snack, like a cracker or small slice of bread...something to buffer his stomach from the acid. Within 24 hours all his symptoms were gone and didn't come back.

When I first notice symptoms of a cold coming on (slightly swollen throat or my nose starting to drip or pressure in head or just a feeling some kind of bacteria has gotten into the body), I immediately start the following:

If the symptoms are mild, I will take 500 to 1000mg Vitamin C powder (can also use capsules or tabs) every 2 hours. I sometimes add it to my Apple Cider Vinegar and Honey tea, or just with water or just before a meal...but I never take the C on an empty stomach.

If the symptoms are bad, I will take 500 to 1000mg C every hour.

What happens in the body is that when a person has a cold or flu, they tend to have to urinate more. When sick the body uses up Vitamin C very fast. Even if you take 5000mg or more in one shot, within 2 hours all of it will be gone through the urine. That's why it is so important to take it in smaller doses every hour or two.

I discovered this approach from Adelle Davis in her book Let's Get Well...it was published in the 1960s. I have been able to kill all cold and flu symptoms within about 24 hours for over the last 20 years...I have not had a full blown cold or flu since. The Keys are (1) start early when first get symptoms and (2) take the Vitamin C every hour or two until better.

Vitamin C cured my wifes' bacterial vaginosis. She used 250mg of ascorbic acid by breaking off 1/4 of a 1000mg caplet and using it as a suppository. Within one day the odor was gone. She plans on continuing this for a week or so to make sure it's gone.

Hi Elaine,

I believe you meant 6 grams (g) of vitamin C, not milligrams (mg.)...6 grams would be 6,000 mg.. Linus Pauling took about 10 grams a day.

That is very interesting that Vitamin C cleared up your mucous enough to sleep through the night. I occasionally have a stuffy nose when sleep. I'll try this out and take 6 grams and let you know if it works for me. I currently take 3,000 mg a day.

Does Vitamin C causes hair fall? I have been asked by doctor to take iron tablet as my hair was falling. I learned that iron tab (300mg) taken with Vitamin C helps to absorb iron (folic acid) faster. So I took together Vitamin C and iron tablet. But to my surprise my hair fall increased as never before. The rate of fall is higher. I almost lost so many hair. I am confused why it is so. May be Vitamin C is acidic in nature and that may causes hair fall? Or It is some thing like fall is the season for hair fall too?

I agree with people linking Vitamin-C to cold sores. So, I am not alone! When taken in a dose as high as 500mg I start to get cold sores or ones already present get worse, talking about lip-condition here. I wonder what the explanation is! Reacta-C is one I took and it gives me cold sore symptoms. If I buy a formula where Vitamin-C is a part, I make sure it's not more than 50mg or else I don't buy the formula at all. B-Complex for eg. comes with Vitamin-C as part of it, some with 50mg some with 500 mg. So yea, may be taking Vitamin-C in small doses is okay or make your own like suggested here by grinding dry citrus fruit peels.

Re: Polio and Vitamin C Side Effects -

The side effects from a massive dose of vitamin C is diarrhea. At 400 mg per kilo taken every 2 hours, if we assume a person's weight is 60 kilos, the total dose amounts to 24,000 mg. I believe the dose is high. However, my own approach towards killing any virus, or bacteria lies in the frequency of dose rather than the amount of dose. The other is a combination of other supplements has synergy and hence the dose can be further reduced by 1/2.

Vitamin C has antiviral properties and it's weakly antiviral and this is why the dose is so large. However, it's possible to reduce from 24,000 mg to just 12,000 mg hourly dose. My experience in killing viruses is that the frequency of dose is ideally between 30 minutes to 1 hour. Therefore it's also possible to reduce from 12,000 mg to just 6000 mg if this is taken every 30 minutes. That's an equivalent of 6 tablets/capsules every 30 minutes. There is an indian shilajit (humic acid) that can be applied on the skin when the powder is mixed with water, and taken internally, it's a very broad spectrum antiviral. If that's taken 4 or 5 times a day, I believe the hourly dose of vitamin C 12,000 mg can be reduced also to 6000 mg. If the aspirin were used, the vitamin C will be synergistic and you just need 3000 mg every hour when it's taken with aspirin 500 mg dissolved in a cup of water for only 6 doses per day, not exceeding 3 or 4 days. Most of the polio viruses should be gone in a matter of days (theoretically speaking), and 25 mg of zinc is taken once a day for a week.

The iodine lugol's solution is taken every 3 hours 4 drops for every 3 or 4 hours. These are combination of remedy that should reduce the vitamin C dose to just 3000 mg on a two hourly dose, should make the approach more easily to do in practice. Iodine is kept up for over a week or so. Hence the remedy is carried only for a short period, if done right (in combination or frequency) the viruses usually go away quickly. If they viruses do not die within 3 days to one week, I believe the remedy needs to be redo until which if done properly viruses get killed rather quickly within a matter of days.

For instance, I got the swine flu viruses correctly both dose and frequency and it's a one day cure. A few may last up to 2 days, before swine are completely dead, however, one day was more than enough for that case. As in polio if done right (not necessarily this remedy), it should be killed by a week or so.

side effect of vitamin c on polio affected person

i sir/madam, my name is Rahul and i am handicapped (affected by polio) my age 20 years. And i have polio since i was 5years. i read an article on internet of Dr. klenner about vitamin C helps to cure polio but the amount of vitamin C is mentioned is very high (400mg) per kilogram of weight in every 2hours so i just want to if i take vitamin C in such massive amount then is ther a chances of any side effects and what are they? please help me.Thanking you

Thanks for your suggestion Bessie. Thanks also to Joyce from Joelton,TN who was very accommodating with her response via email. So far I have tried 10% baking soda to 90% ascorbic acid combination based on the ratio I observed in a lot of commercial sodium ascorbate. So for example, for 1 tsp of baking soda, I mix this with 9 tsp ascorbic acid. From this, I use 1 tsp of the mix in one or half a glass of water or juice. So far I don't have any issue of diarrhea from taking such combination. I take twice a day for days that I need more immunity.

I have a very odd situation. Vitamin C causes strange side effects in me and my children. These include small, hard nodules in our fingers, sores in our mouths and bruising on our arms. I am 49, but it has always been this way. my children have the same symptoms. My dad has gout ( I have never had any symptoms of that), but I wonder if the two conditions could be related? Has anyone else had anything like this?

In response to Lilydy's question about making Sodium Ascorbate - I was told to use twice the amount of Vitamin C powder to baking soda (example, 1 teaspoon of Vitamin C powder mixed with 1/2 teaspoon baking soda). If you mix it with water, it will fizz up so just add a bit of water, wait until the fizzing stops and then add more water. Be careful not to take too much all at once, though. It can upset your stomach! Hope this helps.

Hi I just want to ask if anyone has an idea how to make your own sodium ascorbate? I read somewhere about mixing equal amount of baking soda and ascorbic acid, is this correct? Any suggestion will be appreciated as it is expensive here to buy the commercial ones. Thanks.

I was diagnosed with genital herpes around 1996, from that time I had to take medicine for that every 3 repetitions by year.

In 2001, I started to take a daily dose of 500mg of Vit C, and after 9 years my genital herpes never returned. I continue taking Vit C without any side effects.

Vitamin C and youthful skin: I knew someone who used to take Vitamin C crystals several times a day. He looked so young and his skin was always glowing and healthy. He was 40 at the time and played sports so he was in the sun a lot. He told me the he took the vitamin C for a lot of reasons but a bonus was that it worked on the collegan in the skin. He explained it this way. If your skin is the bricks, the collagen would be the morter between the bricks. As you age the mortar (Collagen) breaks down and things start to sag. But the vitamin C works to keep that collagen firm. Naturally I started taking the Vitamin C right away. This was over 12 years ago. I take Ester C, and have gradually increased my dosage up to 5000 mgs a day. I will take 2 500 mg capsules upon waking, then with all three meals, then at bedtime. This amount works for me and I learned a lot about it from reading the works of Linus Pauling. I found that I was the one who didn't get all of the virus's and colds going around. I used to get sore throats all the time, no matter what the season, which sometimes led to wicked strept throat. No more. I'm sure this is because of the Ester C. I'm almost 51, and no one has guessed my age to be in my 40s yet. I keep my age to myself but not the benefits of vitamin C!

i have a question about vitamin and mineral supplements. for several years i took emergen-C daily. however recently after reading about it containing excito toxins and checking the label and seeing that and perhaps MSG - i stopped. now i am only taking a multi vitamin and some triphala powder (very high in vit. c) and also some ACV each day. my question is: does anyone know a good replacement for emergen-C? i don't want to take a bunch of pills, would prefer a powder i can mix in water or juice. i am just worried that now i am not getting enough minerals!

OR SHOULD I JUST START TAKING THE EMERGEN-C AGAIN??? help!
i never really had any side effects that i could tell from it.

Hi, I got my EmergenC at Whole Foods in Vancouver (925 Main St location). Packaging says the C is from aspartic acid, not asorbic acid.

I purchased my Emergen-C at Walmart. It contains Vit C as ascorbic acid, zinc ascorbate, chromium ascorbate, but below at the bottom after other ingredients: fructose, citric acid, natural flavors, tapicopa maltodextrin, malic acid, silica, gylcine, aspartic acid, tartaric acid, cysteine hydrochloride. I can't believe that ingredients would be different depending upon where purchased.

We went to Whole Foods last week, and Trader Joes today, and checked out the ingredients of the Emergen-C sold at both stores. None of the ingredients in any of the Emergen-C boxes listed aspartic acid as the form of vitamin c. It was all vitamin c in the form of Asorbic Acid. Readers from other territories (outside Atlanta), if you get a chance to look, please report your findings. Thanks!

hi, Dianne. Yes, they've been adding aspartame to Airborne since the teacher who invented the formula sold it to a big pharma company (if I am recalling this correctly). Amazing how they try and hide the toxic ingredients with all sorts of other names! We all really have to keep up with the latest research in order to notice the changing names.

emergen-c caused a herpes simplex outbreak. I was shopping at Trader Joes and I picked up a pack of emergen-c. thinking that it will supply me with needed vit-c. I took one packet right at the store with water that I bought there. I felt really weird after taking it. I read the ingredients and I noticed natural flavors and natural sucrose. I know from previous time that anything edible containing natural flavours it is MSG. No sooner did I get into my car to leave,my lip became inflamed and I had the start of a cold sore. I returned to the store and got my money back. I later spoke to the manager about the situation and he said he cannot pull anything off the shelf. It has to be done by headquarters. Now I only depend on good quality Vit C. Emergen-C is on my not-to-buy-list!

Thank you Catherine in Seattle for sharing this. I would not have known -- just goes to show that a person needs to read the label on everything -- even "trusted" products that seem healthy. I would like to give everyone a heads up on two other problem products within our food supply. There may be a few of you that have not heard that there is yet another reason to avoid High Fructose Corn Syrup -- mercury! Here is a link I found -- http://gristmill.grist.org/story/2009/1/26/132619/467 --but go ahead and google this yourself. Also, to my horror, I purchased a bottle of Balsamic vinegar the other day, used some and then noticed on the label, A LEAD WARNING! I am still researching this, but wanted to share a link with you http://ecochildsplay.com/2008/01/18/why-is-there-lead-in-my-balsamic-vinegar/

Evidently a person would have to consume a lot of vinegar to reach the lead level in California's Proposition 65. Even so, I feel that I don't need any extra lead :), so I am going to start buying certified lead free vinegar. I know that I am probably ingesting other toxic things in my food, but what is a person to do? I just say a little prayer over my food and try to do the best I can with what I know.

I too experienced something like the above post in my case it was very odd and scary palpitations. After going to the doctor several times and being in the emergency room more than once I lowered the C and things started to get better. I had EKG's performed and wore a halter monitor but of course over the 24 hours period I wore the monitor nothing happened. I found more information on the internet about this before but I can't remember where. At the time of problem I was taking 5-15 grams a day of chewable sodium ascorbate with 1 gram of sugar in it (unfortunately). I now take 2-6 grams a day of pure powder ascorbic acid and I always try to take it with a meal and a cookie. :) In addition I supplement with 250mg-600mg of magnesium.

Jacqueline do you mean 200 grams? 200 milligrams is not that much.
"read about a doctor/researcher who would give up to 200 milligrams per day"

wow! i am upset by this. i have been taking emergen-c for years and i didn't know that this was anything other than an amino acid.

so - i need to find another vitamin/mineral blend that is easy to take. i just looked up airborne's ingredients and am sad to say that they contain acesulfame potassium which is an artificial sweetener... as well as sorbitol...

can anyone give me the name of a product that is similar to these and is safe?
thanks

Hello Catherine: Unless you consider killing off your brain cells good, ingesting excitotoxins, or neurotoxins is very bad. When you read up on excittoxins, you will find the same two majors so rampant in our processed foods, monosodium glutamate and aspartame, are also blamed for making our bodies kick out excessive insulin which starts us down the progression of insulin resistance and development of diabetes mellitus, type 2. Personally, I don't care to ingest any of them but it is very difficult to avoid them in our foods these days.

Russell Blaylock tells us that any hydrolyzed plant (corn, soy, pea, etc) protein is the most deadly form of all of MSG because it kills off two different types of neurons, because it contains both MSG and aspartame. Since this would hold true for ingredients listing both monosodium glutamate and aspartame in the ingredients, stay away from those foods containing either one these toxins. Read labels carefully before buying as I have found a couple of canned vegetables listing ingredients: monosodium glutamate, spices, hydrolyzed plant protein, and natural flavors all on the same label.

To make this story more pitiful, they were not at the end of the ingredients list and the ingredients are supposed to be listed beginning with what it contains most of first and listing those with very small amounts last.

I feel the same way after taking the emergen-c. I had to give it way. I didn't know that Aspartic acid was an excitotoxin.

Aspartic acid is a well known excitotoxin and so is monosodium glutamate or MSG. In the long run it's going to destroy the immune system through a neurodegenerative disorder. Once the excitotoxins is destroyed the immune system is down. Now in a pharamaceutical formulation adding this results in the need to take that since you get sicker and so you might feel some relief, the long term is it's going to make a person sicker, which result in greater sales for product with excitotoxins added. Now imagine a child who is a borderline autism, ADHD, these can result in many other neurodegenerative disorders and metabolic acidosis. As for me decades ago I took accidentally soft drinks with aspartame resulting in deafness, but also a permanent partial macular degeneration of the eyes. So the systematic destruction is almost wholesale if given long term use. Luckily Emergen C is not sold in Thailand, although some friends of mind given me this, I don't take it. I prefer to buy bulk vitamin C and mix them myself. There are other excitotoxins, but aspartic acid, aspartame, monosodium glutamate, and glutamic acid are the most well known.

There are other things people need to know that also accelerates aging process besides excitotoxins, well known in research circles, they are ketones and aldehydes. In one study, 36 out of 37 perfumes contain ketones, commonly in the form of musk ketones. Aldhydes are perfumes used in many cometic products, such as Chanel No. 5, but also in many consumer products, such as detergents and soap. The third common one is the bisphenol A, which acts like estrogen found in nearly all canned products that have plastic linings, and benzene, a degradation of sodium benzoate is found in most soft drinks.

I remember a newsreporter who uncovered U.S> black ops, that appeared on "What's My Line", a close friend of Marilyn Monroe, before both are dead mysteriously and the drinking water were heavily added using fluoride and LSD. Thus fluoridation and chlorination, if some of these are used in assassinations, I doubt I want to use them in my drinking water supply.

Therefore most effervescent products sometimes they are not labeled so I ended up calling the factory sometimes. One easy way to measure excitotoxin poisoning is tthat the urinary pH suddenly become very acid, such as pH 5.5 or lower and even taking more baking soda barely raise the pH long enough to be satisfactory. Such as it can't raise the pH for the entire day. It also takes weeks for the pH to be near normal after taking b complex and baking soda for a week or two. A long term taking of this can also resulted in higher urinary sugar and damaged pancreas, besides damaging the brain. One of the worse advertisement I have seen is Michael J. Fox supporting Diet Pepsi, which contains aspartame, and he himself has Parkinson's disease, which will make such conditions much worse. The remedy is not to take aspartame for Parkinson's disease or to undergo stem cells, since it's not yet legal at the moment and stem cell research has been blocked for at least 8 years. Methylene blue taken at 2 drops at 0.1% concentration might reverse some of the effects of excitotoxins as it is one of my remedies for Parkinson's disease also.

Taking excitotoxins is a long term damage that may lead to degenerative disorders, metabolic acidosis, and lowered immune system. Therefore I would avoid them as best as I can.

I was fighting a sinus infection last week after landing in California and went to a Whole Foods to get some Vitamin C. I decided to get Emergen-C to add to water because it had a really tempting fruity flavor. Immediately after taking my first packet (which was delicious), I felt a weird sensation in my head and then I got really edgy (as in bad mood edgy). I read the ingredients on the box and sure enough, the vitamin C used in this brand is Aspartic acid, an excitotoxin. The Emergen-C also contained "natural flavors", aka MSG. I waited 24 hours and tried again to see if I would have the same side effects. Again, within a minute of drinking the packet, I got the same sensation in my head. My question is, are you doing more good or harm to the body when you take this form of vitamin c?!! Also, does Whole Foods know what they're selling? I thought they had stricter standards than most health food stores about supplements! I now need to check the ingredients on the dissolvable vitamin c from Trader Joe's that I have at home to see if it's the same stuff. GRRRR!!!

Hi Chuck, I didn't see anything mentioned about the cause of your pain, but if it started after the fall 2 years ago, at this stage it will probably be called traumatic arthritis.

I would suggest two things for that pain if it started shortly after the fall. The first one is MSM (methylsulfonylmethane), Now you know why it is known as MSM. The second one is old Edgar Cayce's castor oil packs. When you research on MSM you will find that it is most frequently used by holisitic practitioners to keep down inflammation and promote cellular regrowth. It is also a first cousin to sulphur (a natural mineral in our bodies) and what our bodies metabolize DMSO to. I think between the two, you will find the pain, much less, if not totally gone within 2 weeks after starting them.

Don't worry about MSM causing a reaction if you are allergic to sulfa drugs. I cannot take sulfa drugs without feeling worse after 3 days of it than I was before starting it for an infection. However I can take the MSM without problems, and I have plenty of allergic problems.

I was involved in the building of the Lipitor factory for the then Warner Lambert in Ringaskiddy, Cork Ireland. The Irish have never been good at keeping secrets. Lipitor comes from garlic.

Eat garlic, it doesn't have the side effects of Lipitor.

When you think about it, your body is the result of a million years of development. It has been 'built' to run on natural products not the chemicals that pharmacuticals have designed in the last 20 years.

If you drink milk, you might benefit from researching milk, and especially the homogenization process. This process creates fragmented jagged molecules which then pierce arteries causing cholesterol to patch up the wound, thus clogging arteries. Please remember that milk is a big business. I discovered this by reading a book called Radiant Health (author: Peskin) which exposes the food and health industry. I believe homogenized milk causes high cholesterol, heart disease and stroke. I believe that after age 2, we do much better getting our calcium from non-milk sources like vegetables.

We are not defenseless against the food and health industries, but we have to be advocate of our own health by educating ourselves. Blessings.

Lipitor Muscle pain: I notice one person commented about taking Vit C in large doses to help controlling cholesterol. I have read a lot of similar articles as I have the same muscle pain that all the articles talk about in taking Statin drugs. My question is: If I stop taking statin drugs and use Vit C do the muscles rebuild - less the pain and how long does it take. I have been taking Lipitor and swithched to Sinvastain a year ago and have now developed severe muscle pain in legs. Will my blood test indicate a real cholesterol number or will the Vit C distort the cholesterol reading. I get my blood tested every 6 months.
Thanks

I added Baking Soda to my ACV treatment and had many of the side effects others mention on this site. Baking Soda lowers Vitamin C levels and this can lead to symptoms of scurvy. I had to do a lot of research to find this out. I woke up with a purple spot/bruise on my leg and that convinced me, as I had not bumped into anything to bruise myself. The purple bruise looking spot is a sign of scurvy. Luckily, it was recommened to me to take Vitamin C for Constipation. I was sooo sick (my asthma was out of control) last night and the night before. I did not know that Vitamin C actually helps Astmatics.

I took 6 mgs of Vitamin C last night in error. I picked up the wrong size of measuring spoon!!..luckily! I had been up the prior two nights coughing up mucus, but last night I slept through the night. I couldn't figure it out since I needed to take bendryl the other nights just to not choke on the mucus. It appears that the 6 mg of Vitamin C did it's job to replenish my Vitamin C and to help with my asthma.

I woke up with the usual morning junk to cough up and spit out. I took 1000 mg of vitamin C and it stopped this problem dead in it's tracks. People need to read about what vitamin C does, especially for people with Asthma and food allergies. Also, the baking soda should NOT be recommended on this site.

It depletes the Vitamin C. If someone is already low in Vitamin C it can cause Survy Symptoms as it did in me.

I love this site, but I think promoting Baking Soda that depletes Vitamin C is wrong. Also, I love Apple Cider Vinegar and it is promoted her as the top natural relief, but I never hear any talk of vitamin C. It works wonders for Asthma, Hay fever and a load of Respiratory illnesses and other illnesses.

Dream Inducer: I stumbled upon this years ago when I was taking as much as possible to battle a nasty cold bug, but chewable vitamin C tablets (500mg) right before bed produce vivid dreams. I occasionally have some just before bed for fun, and it never fails.

Regina you're right .i've been witnessing my brother suffering from the result of too much drinking liquor (wine). As his brain tissue was very much affected by acidic tension and crush its normal function down to earth level (became FOOL) ,as being poor in status living, things go hopeless and devastating. Having so many empathetic and sympathetic experiences, i give him ____ C 10,000 mg or 20 capsules of it. After taking it, a remarkable result had shown automatically in a couple of minutes.Thanks to ____, my brother now is in good condition(good health) and strong through it. He's now including it in his daily meal.

in my opinion...it's important to learn and study vitamin c in very simple way by using an alkaline tester (acid tester used by doctors) in order to know the veracity (truth) on your vitamin c supplements and also put your supplements in in a clear glass of water and observe it thouroughly, anything made it muddy or foggy or dirty looks are SYNTHETICS or acidic. In many ways, make sure your supplements are Alkaline based not acidic base by knowing the PH factor that our body requires.

hope it ads something on you and please do not criticise my English workmanship or my weakness in words, for such experience cannot be question by someone like you. thanks

Have been reading your Vitamin C section; I do so wish you would have a link to Dr. Klenner's paper on Vitamin C, particularly the pregnancy section. Dr. K. was able to help expectant mothers who would have died otherwise by prescribing Vitamin C for them. In fact, the mothers who took Dr. Klenner's prescribed doses of Vitamin C had no stretch marks and easy births.

Sometimes you need an objective health professional to tell you whether taking Vitamin C is related to symptoms that you are experiencing. Or is it a component of the Vitamin C, such as aspartic acid, or the type of Vitamin C you are taking? E.g. taking straight ascorbic acid in water can corrode your digestive tract because Vitamin C is an acid. That's why it's usually buffered with sodium. If you take calcium ascorbate, be sure to balance it with magnesium citrated (magnesium oxide is not readily absorbed).

As for a person being "allergic" to Vitamin C, that is impossible. Vitamin C is a universal detoxifier. High doses of Vitamin C are used to stop hayfever. It has to be a component of the tablet, not the Vitamin C, that is causing an allergic reaction.

We do backpacking in remote areas in northern Michigan where mosquitoes and black flies can make a trip unbearable. I read about taking Vitamin B6 to prevent bites, tried it and found it completely successful. But one time when backpacking with our daughter, I had forgotten the B6 but was taking Vitamin C up to my bowel tolerance level for a specific medical problem. So my blood and cells were full of Vitamin C. I noticed that my daughter's legs were covered with mosquitoes and black flies and in a few minutes, each bite would swell up and become red. I was surrounded by flies and mosquitoes but either I was not bitten (I did not feel anything) or I did not have any reaction. I think that the mosquitoes do not like the high acid content of the blood (I was taking the acidic form of Vitamin C). In addition, when cell and tissue fluid are saturated with Vitamin C, edemas will be removed by the body very quickly. I think this probably is why bites either do not swell or do not last very long if people are taking Vitamin C.

In reference to C side effects I have a heart failure problem and I mega dose alot of supplements for this condition. In regards to Vitamin C I normally take 6000mg divided into 3 doses daily. In the winter during cold season I increase my doseage to 9000mg daily to ward off colds etc. I personally use vitamin C with rose hips absorbic acid capsules. The only side effects I am aware of not to say there may be others is loose bowel movements if you injest more C than your body can handle. No big deal. Just back off a little. I also found in my case I can gradually build back up slowly with no more of these issues. While we know the C vitamin is a plus for many ailments you might want to consider a B complex supplement as well. I personally prefer the 100mg complex capsules and take them 3 times a day with the C. The benefits are numerous. But hey! I'm no doctor. I just know what works for me. One more tip if I may. Mega doses of water soluable vitamins for the most part are safe within reason where as oil base supplements is a whole different can of worms and should be monitored carefully. Spence

Can vitamin c cause urinary tract burning sensation and hair lose? I take 1000 mg daily for one year. is it overdose? Im 45 yrs old.
