High vitamin C intake shown to lower risk of coronary heart disease by 66 percent

iv-vitamin-c-bag(NaturalHealth365)  Why does conventional cardiology ignore the lifesaving health benefits of vitamin C?  Cardiovascular disease, the number one cause of premature death in the United States, claims more lives than all types of cancer.  And, the point is, we can fix this.

In reality, it turns out that daily supplementation with a safe and inexpensive vitamin can help provide major protective benefits to the heart, while helping to prolong life. Extensive research has confirmed that vitamin C drastically lowers the risk of developing cardiovascular disease – in one study, by as much as 66 percent.

What the research reveals about vitamin C intake

In a study published in Journal of the American College of Nutrition, researchers assessed the daily vitamin C intake of 108 men, and qualified the number by thirds. Incidentally, many of the men in the study were smokers – a notorious risk factor for all types of heart disease.

The team found that men in the highest third of vitamin C intake had a 66 percent less chance of developing coronary heart disease than men in the lowest third. To say it another way: men who ingested higher levels of vitamin C were two-thirds more likely to avoid developing heart disease than men in the lowest third – a truly encouraging result.

Although the exact mechanism by which vitamin C provides such dramatic heart benefits is unknown, researchers think it has to do with the vitamin’s ability to prevent and alleviate endothelial dysfunction, the stiffening of arterial walls that can impede blood flow. Vitamin C seems particularly effective in reducing endothelial dysfunction – especially in smokers.

Large long-term studies support vitamin C’s preventive and therapeutic value

Many in conventional medicine tend to underplay or negate promising vitamin C research. Naysayers may point to small study size or short duration, explaining results away as a statistical fluke.

But well-designed, long-term studies on vitamin C’s benefit are piling up. One study, in which researchers followed subjects for over a decade, demonstrated that vitamin C supplementation of at least 700 mg of ascorbic acid a day dropped risk of cardiovascular disease by 25 percent. A study of 11,000 adults confirmed that taking 800 mg of vitamin C a day cut the rate of heart disease by 42 percent in men and 25 percent in women.

In a 2003 observational study conducted by the prestigious Harvard Medical School and published in the Journal of the American College of Cardiology, 85,000 female nurses were followed for 16 years. The study showed that women who used supplemental vitamin C reduced their risk of cardiovascular disease by 28 percent.

Vitamin C deficiencies can lead to life-threatening disease

It’s a logical question: if supplementation of vitamin C decreases risk of heart disease, do deficiencies of vitamin C increase it?  Researchers set out to answer that question; here is what they found out.

One study of middle-aged men with no history or evidence of pre-existing heart disease showed that those with vitamin C deficiencies were 3.5 times more likely to suffer heart attacks than those who were not deficient.

Also, a study contrasting men who had just suffered their first acute heart attack with healthy volunteers demonstrated that the heart attack victims were dramatically lower in plasma levels of vitamin C.  The upshot seems clear – avoiding deficiencies and maintaining optimal levels of vitamin C could be a vital tool against life-threatening heart attack.

Vitamin C improves outcomes after heart attack

In an even more hopeful note, research seems to indicate that it is never too late to benefit from vitamin C’s protective effects on the heart. Researchers think that vitamin C’s antioxidant properties can help alleviate oxidative damage from heart attack.

Studies have shown that vitamin C reduces the extent of the destruction to heart muscle after a heart attack, while cutting the risk of future events. Vitamin C also improves electrical conduction throughout the heart muscle, decreases clotting factors that increase stroke risk, reduces inflammation, and prevents destructive changes in heart shape and operation. In addition, vitamin C can Increase exercise tolerance following a heart attack – while reducing the oxidation of dangerous LDL cholesterol.

Animal studies have suggested that vitamin C can even help reduce damage from ischemia-reperfusion injury, a type of post-heart attack oxidative injury in which blood previously cut off by the attack rebounds suddenly back into the area.  And, finally, researchers believe that vitamin C can help protect against atrial fibrillation – a type of irregular heartbeat – along with weakening and enlargement of the heart, or dilated cardiomyopathy.

Current vitamin C recommendations are a joke

The current Required Dietary Allowance of vitamin C, as advised by the Office of Dietary Supplements, is a paltry 75 to 90 mg a day – which natural health experts say is just barely enough to prevent scurvy, a result of extreme deficiency of vitamin C.

Obviously, the current recommendation isn’t even close to the level needed for good health.  Experienced, integrative healthcare providers tend to advise taking anywhere from 1,000 to 6,000 mg per day, depending on individual needs and conditions.  In many cases, especially when dealing with serious chronic disease conditions, much more will be needed on a daily basis.

As studies have shown that vitamin C levels quickly drop in times of infection, it is vital to replenish the body’s stores by supplementation in times of illness. It’s also beneficial to maintain optimal vitamin C levels to help keep diseases – including heart disease — from developing in the first place.

    This article states the truth. It is a well known fact that heart failure is at times a result of a lack of nutrients including the B vitamins. All vitamins are critical and none more so than vitamin C.

    I can just image how many lives can be saved with this information. What a simple solution to such a wide spread health concern.

    I remember my mother using a glass citrus juice squeezer to make us orange juice for breakfast. Both parents said we had to have it for the vitamin C in it.

    Somehow, I don’t think parents think in terms of the vitamins and minerals in the food they give their children for breakfast. If they did processed cereals and Pop-Tarts wouldn’t be on the menu.

    For anyone reading this it should be a wake-up call. Everyone’s eyes should now be opened to the benefits of vitamin C. I am so impressed with what this vitamin can do. It took away my seasonal allergies, which meant no more allergy shots.

    When I travel I always take vitamin C with me. When planning a trip in the United States or abroad it is always in my suitcase and purse. When traveling we have encountered people who had already booked their trip months before and couldn’t cancel it when they had either a horrible cold or flu.

    We were on a ride at a resort park and the people besides us were quite sick. My husband and I wound up with it and were sick for the rest of our trip. After that experience we up our vitamin C before we leave and continue taking it so we don’t have to worry about encountering someone with a upper respiratory infection.

    This sure sounds like it can eliminate the need for baby aspirins. My husbands cardiologist tells his to take one everyday. At the same time he says that may not be enough. The doctor would like to add a drugs to his daily routine.

    We never fill the prescriptions, because of the side effects. At the same time we aren’t happy about him taking the aspirin everyday. Many times he just doesn’t take it, now I feel better knowing he would be more willing to take vitamin C as outlined in this article.

    This isn’t new Dr. Linus Pauling published the benefits of high dose Vit C on heart health in 1970, he believed that cardiovascular dysfunction is as a direct result of a lack of Ascorbic acid in the diet and that a combination of Lysine, Proline and high dose vit C taken together could not only prevent heart disease but reverse it in those who suffered from it.
