Even 500 milligrams per day seems like a lot. Isn't the RDA about 60 milligrams? Yes, 60 or 70mg IIRC; that's the minimum to keep from scurvy etc. I think that there is an argument for increasing the RDA for Vit C, to improve health, rather than the 'stave off disease' current level. I don't recall the proposed 'new' RDA, but it might well be the dose in your MVI. The daily multivitamin I take has something like 120 milligrams. An orange has about 70 milligrams, and I've always heard that is an excellent source of C. By way of comparison, like humans, guinea pigs don't manufacture their own vitamin C and they typically need 10 to 15 milligrams per day (typical weight of an adult male is 1 to 1.5 kg). grin And while horses do make their own, some feel that they need more for optimal health, and feed supplements. I like to let them graze on dandilions for this (and other) nutrient(s). Guinea Pigs And Horses Are Good For The Soul! Maru :D __ Do you Yahoo!? Yahoo!

[Listref] Vitamin C and the Heart
http://my.webmd.com/content/article/71/81186.htm ...The data come from 85,118 healthy women studied since 1976 in The Nurses Health Study. Boston Children's Hospital researcher Stavroula K. Osganian, MD, and colleagues found that those women who took vitamin C supplements had lower risk of heart disease. It's a modest effect. Use of vitamin C supplements lowered heart disease risk by 28%. But every little bit helps. Protection came from rather small doses of vitamin C -- up to about 700 mg per day, including dietary sources such as fruit juice. That's no megadose. But it's 10 times the current Recommended Daily Allowance for women... Debbi Wading Through The Backlog Maru __ Do you Yahoo!? Yahoo!

Vitamin C
http://www.upi.com/view.cfm?StoryID=20030331-012146-7230r Heart cells from stem cells via Vitamin C From the Science Technology Desk Published 3/31/2003 5:16 PM View printer-friendly version BOSTON, March 31 (UPI) -- Vitamin C helped embryonic stem cells from mice convert into functioning heart muscle cells, a new study released Monday concludes. The finding could have important implications for patients who suffer damaged hearts, researchers said, though it remains a long way from being incorporated into human therapies. Dr. Richard T. Lee, associate professor of medicine at Harvard Medical School and Brigham and Women's Hospital in Boston, and colleagues took 880 bioactive substances -- including both drugs approved by the Food and Drug Administration and vitamins -- to see what impact, if any, they might have on animal embryonic stem cells. Of the substances tested, only one worked, Lee and colleagues report in the April 1 issue of the journal Circulation. Ascorbic acid -- the chemical compound more commonly known as vitamin C -- caused the new differentiated heart cells to beat spontaneously and rhythmically. We don't yet know how vitamin C yet does it, Lee told United Press International. That's why it's so surprising to us. We're trying to figure it out now. The stem cells are fetal immature cells that can develop into a variety of cell types throughout the body. Scientists have placed high hopes on the prospect that stem cells will help treat a host of chronic and debilitating illnesses such as Alzheimer's, diabetes and even cardiovascular conditions. Vitamin C is known as a potent antioxidant, meaning it can combat harmful molecules in the body. However, Lee said vitamin C's ability to transform mouse embryonic stem cells into heart muscle cells doesn't appear to be due to its antioxidant properties. Other antioxidant vitamins, such as vitamin E, were also tested and found to have no effect. The vitamin exposure helped regenerate heart cells easily, Lee said. Although, he said, these are mouse cells, so one of the questions we don't know is if this will work in humans. Lee added the finding is so promising since physicians were taught for decades that once heart cells died, whether through a heart attack or heart failure, nothing more could be done. This research suggests new heart cells could be grown to replace destroyed ones. Dr. Nieca Goldberg, a spokeswoman for the American Heart Association and a cardiologist at Lenox Hill Hospital in New York, told UPI she found the research very interesting. Heart cells become irreparable during heart attacks, infections, and congestive heart failure, Goldberg explained. Given how common heart disease and heart attacks are in the United States, the ability to regenerate heart cells would be very useful. According to the AHA, there are about 550,000 new cases and more than 51,500 heart-failure deaths each year as the result of heart attack, genetic disease, or other causes. However, Goldberg said, Before we can get to the human side of research, this is obviously a small step toward learning more about regeneration of heart muscle. This is not ready for clinical applications. Goldberg also cautioned: In no way should this mean taking vitamin C (on your own) to regenerate heart muscle. This study is just one small step. ___ http://www.mccmedia.com/mailman/listinfo/brin-l
vitamin C [L3]
http://web.archive.org/web/2930151442/http://www.healthyideas.com/heal ing/spotlight/allergy/cblocks.html Vitamin C Stops Histamine There's no doubt that vitamin C can help tame allergic reactions, at least under laboratory conditions. Several studies have shown that high levels of vitamin C help reduce histamine release from mast cells and also make histamine break down faster once it is released. Not only that, but studies have also shown that vitamin C deficiency can send blood levels of histamine through the roof. Only two studies have been done in humans, however. One small study, by researchers at Methodist Hospital in Brooklyn, New York, found that people who took 1,000 milligrams of vitamin C every day for three days had significant reductions in blood levels of histamine. In another study, Italian researchers found that people with hay fever were better able to maintain the volume of air they could exhale if they were taking 2,000 milligrams of vitamin C a day. (In many allergic reactions, air passages narrow and restrict the flow of air into the body.) Other studies have shown that vitamin C may also help dampen some of the inflammation associated with chronic allergies. My experience is that vitamin C can have modest beneficial effects for inhalant allergies and asthma if it's taken on a regular basis, says Richard Podell, M.D., clinical professor of family medicine at the University of Medicine and Dentistry of New Jersey Robert Wood Johnson Medical School in Piscataway, New Jersey, and author of When Your Doctor Doesn't Know Best: Errors That Even the Best Doctors Make and How to Protect Yourself. Vitamin C has not been proved to help much if it's taken once symptoms begin, Dr. Podell says. But if you take it before you're exposed to whatever is causing your allergies and allow it to get into your bloodstream, it is helpful, although it doesn't work as dramatically as do standard anti-asthma drugs, he adds. He recommends taking the slow-release form of vitamin C--ester-C or calcium ascorbate--in 500- to 1,000-milligram doses twice a day. (If you take regular vitamin C, you'll see the best results if you take several hundred milligrams three or four times a day, he notes.) - http://www.globalherbalsupplies.com/vitamin_information/vitamin-c.htm Vitamin C (ASCORBIC ACID, CALCIUM ASCORBATE) Information Vitamin C is a water soluble vitamin. Also known as Ascorbic acid (3-oxo-L-gulofuranolactone), Anti-scorbutic Acid, Hexuronic Acid, Cevitannic Acid, L-xyloascorbic Acid, Ascorbyl Palmitate, Ascorbyl Nicotinate. Isolated from fruits, paprika and adrenal glands in 1922 by Dr. Albert Szent-Gyorgi. It can be prepared by synthesis from glucose, or extracted from plant sources such as rose hips, blackcurrants or citrus fruits. It is easily oxidized in air. Man is one of the few mammals unable to manufacture Ascorbic Acid in his liver. Vitamin C Chemical Structure, C6H8O6 Function accumulates iron in bone marrow, spleen and liver antioxidant which helps defend cells from the effects of smoke, pollution and other highly reactive substances called free radicals controls blood cholesterol levels converts amino acids into substances needed for normal brain and nerve functions converts Folic Acid into active form Folinic Acid essential for the formation of intercellular material, bone and teeth essential for the absorption of iron fights bacterial and viral infections helps in healing helps produce anti-stress hormones maintains elasticity of the skin maintains healthy blood capillaries maintains healthy reproductive organs may help protect against certain cancers, cataracts and heart disease necessary in production of red blood cells prevents allergic reactions (antihistamine activity) prevents hemorrhaging promotes healthy cell development and resistance to infections promotes wound healing protects Vitamin E vital for collagen formation which is the connective tissue protein in all cells - http://www.dietitian.com/allergie.html http://health.discovery.com/diseasesandcond/encyclopedia/1952.html - http://www.orst.edu/dept/lpi/infocenter/vitamins/vitaminC/c.html DISEASE PREVENTION The amount of vitamin C required to prevent chronic disease appears to be more than that required simply for prevention of scurvy. Much of the information regarding vitamin C and the prevention of chronic disease is based on prospective studies, where vitamin C intake is assessed in large numbers of people who are followed over time to determine whether they develop specific chronic diseases. Cardiovascular diseases (heart disease and stroke): Seven out of 12 prospective studies, which examined large numbers of people (700 to 87,000) over a number of years (3 to 20), found a significant relationship between higher levels of vitamin C intake and a lower risk of heart disease and stroke (1). The remaining studies, which did not find a relationship between vitamin C intake

I'll have to keep an eye out for further research on the allergy aspect. And even if it's a placebo effect, I feel better for taking extra when I have a cold or flu! :) I'd like to point out that, with the exception of Linus Pauling's work, dosages involved are from 100 - 2000 mg/day; I think the vast majority of people would not have any adverse effects from such amounts (but would urge good water intake for more than 1 gram/day).
