See the symptoms of overdose and toxicity from B vitamins. Years ago, I learned about a very powerful vitamin C supplement called Camu Camu. These berries are known to offer 30 to 60 times more vitamin C than an equivalent orange. So is one mg capsule considered too much daily intake? Would you say the benefits outweigh the concerns? The amount of vitamin C in a camu camu supplement will Is 500mg of vitamin c too much on whether or not it is a dried fruit powder or an extract.
I have been taking about 2 grams per day of vitamin C for the last 20 years was 3 or 4 grams for several years after being diagnosed with serious coronary artery disease. My varicose veins disappeared soon after I started, I assume because Is 500mg of vitamin c too much extra collagen produced, which strengthened those veins. I had a nephrectomy 51 years ago at the age of No of kidney stones or other such issues so far. I don't take any meds. Hi JR - Just to clarify, you need a small amount of vitamin C to produce collagen: This is the recommended daily amount 75 - mg of vitamin C daily, depending on the person.
Taking more vitamin C does not result in the production of "extra" collagen. I am a 72 yo male and have been taking a minimum of mg of C a day for about 50 years. Recently had a malignant tumor removed from my bladder, and underwent chemo. Note that I had zero side effects except for a severe case of hiccoughs which I was advised to treat with shot of apple cider vinegar which worked almost instantly.
I am never been bedridden in 50 years and do not have to take allergy meds. Whereas I was raised on anti-histamines and often had colds that lasted several days. I do take other things. About the zero chem side effects. Before chemo I would run twice a week for 4 miles. All during chemo I ran 4 miles twice a week. I developed a kidney stone in fortunately i was able to pass the stone without too much difficulty.
I have taken mg of Vitamin C every day since I was 25 years old I am now When I developed the stone i did an internet search and found there is enough controversy with respect to the relationship between large doses of vitamin C and the formation of kidney stones for me stop taking Vitamin C--i no longer take it. People can choose to believe whatever studies they want: there will always be conflicting studies.
From a practical standpoint it is not worth taking that risk-- I had always believed in Vitamin C protecting me from colds and felt it acted in some ways like an antibiotic. Perhaps there is some truth to those claims, i do not know: for me, i don't think it is worth the risk to continue taking large doses of Vitamin Cpeople have to make their own decisions.
All this back and forth based on personal experience or opinion, or on one or two studies is not sensible. Anyone seriously interested in the current, collective, medical data on Vitamin C abilities, side effects, and appropriate dosages must read the two outstanding books by Thomas Levy, MD, a cardiologist, on the many, many scientific studies of Vitamin C.
It is by far the most studied vitamin. They are clearly grouped. This is not the opinion of one doctor but the collection and summaries of all these works. I challenge Consumer Lab and all interested parties to read these before commenting further.
I am Asian Chinese 58yo male. I have daily taking mg life extension vitamin C, divided in morning mg, afternoon mg and evening mg all after foods more than 2 years. I have been taking the same dosage of Vitamin C as the above poster 6, mg divided daily for over 7 years, and about 3, mg divided daily for approximately 7 years prior. So it had been a total of 14 years or more. I use a less acidic form Ester-C in powder capsules. I have not had the flu or a sore throat or any stomach or intestinal viruses in all these years, although strep throat and various viruses has passed through those in my household.
I had a very mild cold 3 times that ended in 24 hours. My cholesterol and other common blood work has not shown any areas of concern at all, nor have I experienced any noticeable negative affects. Just sharing my experience.
Is 500mg of vitamin c too much read that whole food vitamin C not ascorbic acid is totally safe.
I switched to whole food vitamin C which is much safer in larger doses. Ascorbic acid may cause issues as you mentioned. Hi Arlene -- Keep in mind that taking high-dose vitamin C from any type of supplement may cause problems. This is has not been found with vitamin C naturally in foods you eat. Supplements with food-based vitamin C are still supplements, Is 500mg of vitamin c too much the form of vitamin C is the same - ascorbic acid. I apologize if another study is the basis for claiming a link between kidney stones and ascorbate.
The methodology and subsequent press on the study most often relied on are both bad. The study stated that the stones were most likely formed from calcium oxalate, which can be formed in the presence of vitamin C ascorbatebut it did not analyze the kidney stones of participants. It inferred type from a different study ascorbate was not studied. This is bad de. Setting de aside, divided 23K Swedish men for 10 years divided into supplement takers and non-supplement takers who took vitamin C.
Those who got kidney stones in each group were tabulated; the group that took vitamin C had a greater risk of kidney stones of perperson-years or 0. Given how this study was structured, this value is well inside the error term of the measurements. This noted, I agree with CR's light guidance that those with a tendency to form oxalate stones might want to minimize their intake of supplements and foods that might contribute to the formation of stones. Thank you Dr.
I have been following the Linus Pauling protocol -- my version -- of daily taking l-lysine 2 gm and a total of 8 gm. The purpose was to relieve attacks of angina --which had been severe, especially at night.
I also could not walk one long block without cardiac distress. The base test had to be stopped,as I developed pain. I expect muscle tiredness will be the only problem this next time. Let me add that I am 81years old, diabetic 1 for 10years. I have not had any problems with this high dosage of vitamin C. Once in a while loose stool but I also take magnesium citrate to avoid constipation which had been a life-long problem. Hi Marina - We are glad that this seems to be working for you.
You are taking 8, mg - 20X that amount. There does not seem to sound scientific basis for doing that, and it could be causing long-term harm. I ran into an issue with too much Vitamin C when I went for an annual physical and my blood sugar test came back high. I am pretty healthy, so this was surprising. I found on consumerlab that taking too much vitamin C can interfere with Is 500mg of vitamin c too much sugar tests, so I had to go back after a few weeks to be re-tested. After I had stopped taking so much vitamin C, my blood sugar tested normal.
So for people taking mega-doses of vitamin C, quit taking so much about a week before a medical appointment where blood will be drawn for testing. I take mg of vitamin C twice a day. I've don't this for years and haven't had a cold in years.
Two weeks ago I ran out of vitamin C, long story.
I was without the vitamin for a week, although my one a day vitamin does contain mg. I caught a cold, a bad one. It has lasted two weeks and I'm still congested, although I'm back to taking more of the C. My family and I are firm believers in higher amounts of vitamin C daily. I agree with John, I too take mg to mg the moment I feel a cold coming on and do this 2 -3 times a day for two to three days. Within that time frame the symptoms go away and I feel fine Guess I wasn't in one of those "studies".
We were introduced to the idea of mega-dosing vitamin C when it was thought that the reason that plant foods promote health was due to the vitamin. Later it was realised that we drew the wrong conclusion and that plants contain around 10, phytochemicals, many of which are now known to activate alling processes in humans who eat these foods. These genes include those for antioxidant enzymes, for glutathione synthesis as well as the Phase 2 detoxification enzymes and heavy-metal chelating compounds.
The notion that 'free radicals are bad' and 'antioxidants are good' is just too simple and is not supported by the evidence; it is a flawed theory but one which is still part of the conventional wisdom upheld by the supplement Is 500mg of vitamin c too much as a whole. There are now well-deed studies that show that greater than practical dietary doses of antioxidant vitamins such as C and E and others actually mask the als cells need in order to activate expression of the genes that regulate cell defence mechanisms.Is 500mg of vitamin c too much
