Vitamin C ’til You Poop

I got in a fight with a nasty cold this week. I survived it and want to share what I’ve learned.

Everyone knows that the best medicine for a cold is lots and lots of orange juice. You need to keep fluids moving through you to help flush things out and orange juice gives you the vitamin C you need to fight the cold. But does it really help?

Well, you have to factor in the fructose content of orange juice. Eating straight oranges includes fiber that slows the release of fructose into your body, but fruit juice doesn’t slow the sugar dump so your body gets overwhelmed with fructose. When that happens, your body has to waste energy processing and cleaning up the fructose, and furthermore, fructose itself reduces your immune system’s ability to eat invaders by over 41 percent. It takes more than five hours for your immune system to return to normal.

One of the more damaging food components to our immune system is sugar. In one study, the ingestion of 100 gram (roughly 3-1/2 ounces) portions of carbohydrate as glucose, fructose, sucrose, honey, and pasteurized orange juice all significantly reduced the ability of white blood cells (neutrophils) to engulf and destroy bacteria.

And if you’re eating carbs high in glucose, like toast, then you’re also inhibiting the vitamin C from entering your cells.

In the 1970’s, Dr. John Ely discovered the Glucose-Ascorbate-Antagonism (GAA) theory. Glucose and vitamin C (ascorbate) have a very similar chemical makeup. This theory proposes that elevated glucose levels compete and effectively restrict vitamin C from entering cells. Both glucose and vitamin C depend upon the pancreatic hormone insulin and its signaling effects in order to get into cells.

There is an important receptor called the Glut-1 receptor that activates in response to insulin to allow both glucose and vitamin C to enter the cell. However, glucose has a greater affinity for the insulin receptor. This means that the greater the content of circulating blood sugar the less vitamin C will enter the cell., see also Ascorbic Acid Competes with Sugar in the Immune System

Even worse, the amount of vitamin C in orange juice is greatly reduced through processing. Julia Ross notes

Orange juice – even without added sugar, this, like all fruit juices, is so concentrated in fruit sugar and devoid of the vitamins, minerals, and fiber that should dilute the sugar content that it qualifies as a junk carb. (Most vitamins can’t survive any processing, and most fruit juice is highly processed)

But let’s put that aside and just go with the USDA Nutrient Database stats: 12oz of orange juice contains 30g of sugar and about 150mg of vitamin C. 150mg of vitamin C isn’t going to do anything to a cold. Most people recommend, at the bare minimum, 1,000mg every 3 hours while you have your cold. So that would be around 6 glasses of orange juice every 3 hours, so maybe 24 glasses of orange juice a day. That would result in 720g, nearly 2 lbs of sugar a day, which would significantly suppress your immune system and cause significant inflammatory stress throughout your body.

So orange juice is really not helpful when you’re fighting a cold, but vitamin C is, so what’s the solution?

Enter titrating vitamin C to bowel tolerance. Basically, your body’s tolerance level for vitamin C fluctuates depending on how much you need to fight an infection. You can’t overdose on vitamin C, meaning it’s not toxic. The only effect you will get is diarrhea if you have too much. But that will only happen when your body can’t absorb any more of it. Watch the video below to learn how clinical doctors have documented patients’ tolerance levels fluctuating depending on the severity of their illness.

Alan Smith, a farmer in New Zealand, came back from the dead through the use of Vitamin C megadosing, much to the protest of his doctors, who left him for dead and were about to pull his life support plug. Watch the story on 60 Minutes.

and a follow up

So I took my cold last week as a chance to experiment. I thought I was taking high doses at 10g/day, but I never reached bowel intolerance until yesterday when I used a powder and hit it at 60g. If I had started that high, my cold would have been over much faster, though the dosage I was using did certainly help.

The method & directions for how to do it can be found here:

I made the mistake of starting with capsules (that’s all I had). You should start with a powder in order to find your tolerance, and then you can continue with pills if you prefer. So here’s what you should do if you want to try it:

  1. Buy Sodium Ascorbate. Take 5-10g/hr until you reach bowel tolerance (note: the higher dose you do, the more you could overshoot)
  2. Supplement at that level every 24 hours until your infection is gone. You can switch to taking 1g capsules if you want (don’t use tablets)
    1. Or even better, once you’ve found your level, divide it by 10 and supplement with that amount of liposomal vitamin c. So 50g/day cold = 5g/day liposomal vitamin c. (Learn about lipsomal here) (Or you can just skip finding the right level and take as much as you want)

Note also the suggestions for maintenance level (daily) supplementation when you don’t have a cold. (found at the bottom of here )

Vitamin C megadosing is absolutely amazing and you need to be very aware of it. It’s not just for colds. It destroys every virus, if you take enough of it. Many doctors offer vitamin C through an IV, which I will probably try next time. IVC is used to treat a vast number of ailments, including cancer.

I strongly recommend watching Dr. Thomas Levy’s lectures

    1. It’s a pretty astounding book! Every parent should read it. All of the incurable diseases we are supposed to vaccinate our children against have been cured with Vitamin C. I’m planning on learning how to do intramuscular and intravenous injections in case of an emergency.


        1. Levy recommends:

          For the average healthy adult, taking a daily dose of vitamin C ranging between 6,000 and 12,000 mg will generally meet the body’s metabolic needs. Most adults will need a dosage closer to 12,000 mg than to 6,000 mg. Taking less than 6,000 mg of vitamin C a day would be an optidose for only a few individuals…
          …The practical determination of a vitamin C optidose for an individual is best calculated after determining one’s bowel tolerance as described by Cathcart (1981). Depending upon one’s underlying medical diseases or daily toxin exposure, this bowel tolerance can vary widely from person to person. Chronic cancer patients and chronic infection patients like those with AIDS can have bowel tolerances of 100,000 mg of vitamin C or higher…

          …However, most healthy individuals with an average body size will demonstrate a bowel tolerance effect between 10,000 and 15,000 mg of vitamin C. Once the bowel tolerance has been determined, taking approximately the same dose of vitamin C in three or four divided doses throughout the day will meet the body’s daily need for vitamin C without causing the bowel tolerance “flushing” effect.

          I started taking large doses of C when I had a cold. After I got over the cold, I decided to continue at the highest doses I could until I reached bowel tolerance. I ended up taking between 25-50g/day for several weeks until I finally reached tolerance at 5-10g/day. That’s because you never know what kind of low-level infection you might be fighting, so it’s a good idea to take as much as you can, at least initially.

          Starting with the cold, I ended up consuming about 1.5kg over 3 months… and I felt the best I had in years. Fast forward a few months and it appears (for various reasons) that I probably have sub-clinical Crohn’s disease, which is caused by a bacterial infection called paratuberculosis. Levy discusses tuberculosis in his book and notes that it has a particularly draining effect on body stores of Vitamin C and patients need high doses for quite a while. I had no idea at the time, but chances are high that I was/am dealing with a paratuberculosis infection.

          In cases of a cold, I will take 10g at a time, usually every 3 hours or whenever I start to feel any symptoms returning (at which point another 10g puts the symptoms in remission).

          For maintenance I recommend a time release capsule. I use Solaray 1,000mg 2 stage time release . Another option is Dr’s Best Pure-Way-C time release and there are lots of other variations out there. I usually use an ascorbic acid powder if I’m treating a cold or flu. I use straight ascorbic acid, but some people do better with a buffered version like sodium ascorbate (Levy discusses it in the book).

          For my 3 year old, we give him about 2g/day maintenance and up to 12g/day during a cold.


  1. In your reading, do you ever remember hearing anything about C’s effects on cellulitis? My grandfather has been in and out of the hospital like 6 or 7 times with a recurring cellulitis infection and they keep trying different antibiotics but it keeps coming back. I wonder if vitamin C megadosing might help.


    1. Not specifically, but C would work against pretty much anything they would try antibiotics on. I did a quick google/wikipedia:

      Cellulitis is caused by a type of bacteria entering the skin, usually by way of a cut, abrasion, or break in the skin. This break does not need to be visible. Group A Streptococcus and Staphylococcus are the most common of these bacteria, which are part of the normal flora of the skin, but normally cause no actual infection while on the skin’s outer surface.
      Dental infections account for approximately 80% of cases of Ludwig’s angina, or cellulitis of the submandibular space.

      Levy has a whole book on dental infections and mentions it in this talk:

      from Curing the Incurable:

      Klenner (1974) later declared that he had witnessed the clearing of diphtheria, hemolytic streptococcus, and staphylococcus infections within hours when a vitamin C dose range of 500 to 700 mg/kg body weight was given intravenously and allowed to run through a 20 gauge needle “as fast as the patient’s cardiovascular system would allow.”

      …Nakanishi (1992, 1993) reported that the application of vitamin C directly in a topical fashion to a bedsore was able to “remarkably” enhance the bacteria-killing effect of antibiotics. Nakanishi also noted that Staphylococcus aureus, which had been antibiotic-resistant prior to the addition of vitamin C, subsequently disappeared from the wound.

      Ledermann (1962) reported on the case of an elderly woman with an ulcer on her left cheek. Multiple treatments were attempted to heal this lesion. Cultures detected the presence of Staphylococcus aureus. After the ulcer had been present for over three years, even becoming larger, vitamin C therapy was initiated and healing was complete in several weeks. Ledermann also noted that “no signs of scurvy were observed.” This is strong support for the importance of vitamin C in healing, especially when a pathogenic organism must be treated at the same time.

      Gupta and Guha (1941) were able to demonstrate an inhibition of the growth of Staphylococcus aureus at concentrations of vitamin C lower than that needed to inhibit certain diphtheria and streptococcal bacteria that result in clinical infections readily responsive to vitamin C therapy. staphylococcal infections can also produce toxins that can magnify the severity of the clinical disease resulting from the infection. Kodama and Kojima (1939) were able to demonstrate the ability of vitamin C to render staphylococcus-related toxin harmless.

      It would appear that Klenner-sized doses of vitamin C should also be utilized in staphylococcal infections. As with a number of the other infectious diseases, vitamin C is especially valuable here since it can neutralize bacterial toxins while eradicating the organism. As with so many of the other infectious diseases, vitamin C can always be used to optimize the performance of traditional antibiotic therapy. However, antibiotics can have very undesirable side effects, and vitamin C as a single-agent therapy should be considered if the attending physician feels that the patient is not so critically ill as to be possibly harmed by an antibiotic-free treatment. Because of its ability to cure staphylococcal infections, maintenance doses of vitamin C should be very effective in preventing such infections from taking hold.

      I would look for a practitioner in your area that would be willing to give him C intravenously (and topically). Search for naturopaths or integrative doctors in your area and call them up.
