NEW YORK (CBSNewYork) – Let’s start out by acknowledging that vitamins are essential for life.

Lack of or not enough of certain vitamins can lead to many serious diseases, from scurvy to brain malformations but the fact that we need vitamins has led many to think that vitamins can be the cure for many diseases unrelated to their original bodily function.

That’s now led to the reported use of mega doses of IV vitamin C to treat COVID-19 infections.

I’ve checked with infectious disease experts who all say there is no good scientific evidence to support the use of vitamin C to treat coronavirus infections.

First of all, vitamin C is a water-soluble vitamin, which means that if you take in more than the body can use that day, you’re just going to get rid of it in urine.

Some doctors have reported that some COVID-19 patients treated with high-dose vitamin C have done better than those who weren’t. That could easily be a coincidence and all of those patients were also being treated with the experimental drug combo of hydroxycholoroquine and azithromycin.

And note, too much vitamin C can cause kidney stones in some people.

There have also been people advocating very large doses of vitamin D, an important vitamin for a healthy immune system. Getting enough vitamin D can strengthen your immune system over the long run, but there’s no evidence that it’s useful in an ongoing acute COVID-19 infection.

    Your knowledge is about 150 years behind the times. Here’s a summary of latest knowledge of ascorbic acid.

    It is so funny when farma attack vitamin C as a useless or Devil ( vitamin C (greater than 2,000 milligrams per day for adults) “may” cause kidney stones, nausea, and diarrhea, WebMD.Wow. I would appreciate if he explains more to the puplic. . Stop waisting time..people die because of his ignorance

    You cannot get kidney stones from vitmain c

  4. There is ample evidence in the scientific literature for the efficacy of vitamin C in shortening course of respiratory infections, reducing respiratory distress and lowering mortality from sepsis. It works if taken at a sufficiently high dose. The null effects in some published studies were due to too low dose. I was plagued by chronic, serious, recurring respiratory infections until beginning regimen of 3000-4000mg/day with triple that if becoming ill. Five or so beginning infections not once have progressed to serious illness since starting this six months ago. I use ascorbic acid powder in water but any form will work. Based on extensive research on this, I strongly recommend. Nancy Dockter, MPH

    Does the rainy weather effect the transmission of the Coronavirus.

  6. cole sommers says:

    Coronavirus causes death because it causes viral pneumonia. The lungs fill with fluid and if severe enough causes death. You can’t think of high dose vitamin C as a vitamin. Instead think of it as a potent anti-oxidant free radical scavenger that quenches the cytokine storm that occurs when the immune system goes into high gear to fight the infection.

    A good analogy is that high dose vitamin C given in divided doses throughout the day acts like the control rods in a nuclear reactor. In effect it tempers the overactive immune response that leads to fluid filling the lungs and reduces inflammation.

    It is one important tool in the tool shed to be used in conjunction with supportive therapy and anti-viral medication. It is VERY safe even in high dose, but maybe contraindicated or used with caution in people with kidney disease or G6PD deficiency.
