How Can I Boost My Immune System Fast

Can I Get Very Sick From Taking Too Much Vitamin C Powder? | Ask Eric Bakker

What I Did When Sickness Was Coming On

About 3 months ago I attended a medical lecture on osteoarthritis in the elderly. There was someone there seated near me, who was coughing during the lecture, but frankly I did not think much about it. Some days later, I awoke in the morning with a low grade temperature, sneezing and coughing and felt that I had picked up an upper respiratory infection. I was not tested, nor did I go to the doctors or the hospital to be tested.

I took 10,000 mg of plain vitamin C , 5 times during the day. Yes, I swallowed 50,000 mg of vitamin C during the day from about 6 AM until about 10 PM that night. I awoke the next morning, feeling great, with no symptoms of an infection!

I can tell you many stories about people who take a minimum of 10,000 mg of vitamin C every day on my recommendation, and who all have told me that they are feeling great, and like myself, do not get ill and are not at all worried about their health in this coronavirus pandemic!

Pharmaceutical medicine does not like vitamin C. After all, vitamin C works, is not expensive, and has no side effects. But vitamin C has changed my life, and the life of everyone I know who will take the time to listen and to have an open mind on this subject.

What Are The Health Benefits Of Vitamin C

Besides possibly being able to fight off colds and other infections, vitamin C has a number of important functions in the body. As an antioxidant, vitamin C can help prevent cancer by preventing carcinogens to form in the GI tract as well as in foods.

Vitamin Cs antioxidant activity can decrease DNA damage from oxidation, protein damage from oxidation, and lipid peroxidation. This means that it can help decrease LDL cholesterol and increase HDL cholesterol in your body, which may result in a lower risk of atherosclerosis.

Vitamin C is important in the formation of collagen, which means it helps wounds heal faster and maintains the structure of connective tissues and skin. Vitamin C is essential for certain enzyme reactions in the body, including those that produce norepinephrine and serotonin.

How Safe Is Vitamin C

Vitamin C is very safe. If you get it through food sources there is very little chance of overdosing.

Even if you take supplements of vitamin C, you shouldnt notice any side effects as long as you take the daily recommended dosage.

Even if you take more than the daily recommended dose, your body is usually able to flush out the extra amount so that you dont get a toxic buildup of vitamin C in your body.

Extremely high amounts of vitamin C are considered to be more than 2,000 mg daily for adults. You may notice certain side effects such as diarrhea, nausea, and kidney stones.

Dr. Mark Levine, chief of molecular and clinical nutrition in National Institute of Diabetes and Digestive and Kidney Diseases

For the average person, vitamin C supplements for colds don’t do much of anything, and I don’t recommend them. After I say that I like to explain why: There are a lot of trials on vitamin C and colds, of variable quality and people analyze these, so there are analyses of analyses.

Overall, I say eat more fruits and vegetables.

Vitamin C is often touted as a natural cold remedy. The nutrient is featured in supplements promising to boost the immune system. Nobel laureate Dr. Linus Pauling famously claimed that taking large doses of vitamin C helps thwart a cold.

    Vitamin C In Animals Vs People

    As mentioned in a previous blog post, most animals and plants produce their own vitamin C, and only a few cant.

    The amount of vitamin C that these animals produce is equal to between 5 and 15 grams per day, if they are healthy. They produce much more when stressed or sick. Up to three times more and some animals produce even more than that.

    People must rely on external food stuffs or supplements to get enough vitamin C. Enough vitamin C so that all the body functions that depend on it work in an optimal way and prevent a vitamin C deficiency.

    The challenge is that our bodies dont absorb all vitamin C we take. And we can only store very little as a reserve. Also, vitamin C has a very limited short life in the body and lasts only a few hours.

    Remember, your body is in constant need of vitamin C. Especially when youre sick or stressed. Any kind of physical or emotional stress.

    Heres an interesting study that proves the human body needs more vitamin C when is under stress or sick.

    Vitamin C Dose Chart For Several Conditions

    Dr. Robert Cathcart used vitamin C to treat many illnesses in his medical practice. He found that patients can tolerate more vitamin C when theyre sick.

    In other words, the sicker the person is, the more vitamin C the body can tolerate by mouth before diarrhea occurs. Vitamin C is one of the safest substances.

    The table below is the vitamin C dose chart from Dr. Catchcart. It documents the bowel tolerance doses for many conditions.

    In the table above we can identify how much vitamin C the body needs under different conditions. For example:

    • A person in normal health needs 4-15 grams in 4-6 divided doses
    • Mild colds need 30-60 grams in 6-8 divided doses. Severe colds need much more, between 60 and 100 grams or even more.
    • Hay fever or asthma needs 15-60 grams in 4-8 divided doses.
    • Cancer needs between 15 and 100 grams in 4-15 divided doses.

    When proper amounts are used, ascorbic acid will destroy all virus organismsFrederick R. Klenner. First physician to use vitamin C therapy, with over 40 years of medical practice

    It is interesting that the more severe the condition, the more vitamin C the body needs. And the more frequent the doses should be to maintain high levels of ascorbic acid in the blood.

    Should I Take More Vitamin C When Im Sick

    Many people pop vitamin C pills when they feel a cold coming on. Though vitamin C helps the immune system, it does very little for a cold.

    A study from the Australian National University found that vitamin C supplements did not prevent colds at all. Supplementation, in a few cases, helped people get over the cold a little bit faster since about 8 percent of participants had one less day of sickness due to vitamin C.

    If you want to play it safe and add more vitamin C when youre sick, its still best to do it through food. Add more citrus or greens. Even if the vitamin C doesnt make a difference, the healthy food will help you feel better.

    Vitamin C Does Not Prevent Colds

    “Nobel prize winner Dr. Linus Pauling famously claimed in the 1970s that high doses of vitamin C prevented the common cold,” says Mike Sevilla, a family physician in Salem, Ohio.

    But Pauling had little evidence to back his claim. The foundations of his argument came from a single study of a sample of children in the Swiss Alps, which he then generalized to the overall population.

    Turns out he overgeneralized, and numerous studies have since disproved Pauling’s claim.

    “Unfortunately, follow-up research has shown that vitamin C does not prevent the common cold,” Sevilla says. Yet this misconception continues to live on.

    “In my family practice office, I see patients from a variety of cultures and backgrounds and the use of vitamin C for the common cold is well known across all of them,” Sevilla says.

    In large population studies, people who eat lots of fruits and vegetables high in vitamin C appear to have a reduced risk for various types of cancer, including cancers of the mouth, esophagus, stomach, colon, and lung. But it’s not clear that these benefits come specifically from vitamin C. The Age-Related Eye Disease Study found that a daily supplement containing 500 milligrams of vitamin C, 400 international units of vitamin E, 15 mg of beta carotene, 80 mg of zinc, and 2 mg of copper can help slow the progression of macular degeneration, an age-related eye disease that causes vision loss. But we don’t know what benefits, if any, are conferred by vitamin C in particular.

    Many people take vitamin C supplements in unnecessarily high doses to prevent or treat various conditions for which its effectiveness is unproved. The vitamin C supplements have variously been touted for preventing cardiovascular disease and osteoarthritis, staving off sunburn, and improving the appearance of wrinkles. None of these purported benefits have been verified in scientific studies.

    The recommended vitamin C dosage per day for healthy women is 75 mg per day . For adults, the tolerable upper intake level the highest daily intake likely to pose no risks is 2,000 mg per day.
