How to Do a Vitamin C Flush


How To Do A “C-Flush” or Ascorbate Calibration

Determining Your Individual Need for Vitamin C (Ascorbate)

 A “C-Flush” can be used to determine your body’s need for vitamin C. This is accomplished by taking small amounts of Potent C Guard Powder every 15 minutes until you have met your body’s need for Vitamin C. I only use Perque Potent C Guard Powder for this, as it is very pure, gluten-free and does not contain harmful excipients.

***Also, it is important to note that everyone is different and that this is not recommended for everyone. This is NOT medical advice. I am not a medical doctor, I do not know your personal situation, and you should not interpret this as my advice for you. Consult your healthcare provider to find out if a C-Flush is recommended – or not – for you.***

The “flush” occurs when your body’s need for Vitamin C is met. The time it takes to flush is different for every individual, so please allow an entire day – when you can be home – to do your first flush. Ideally, start first thing in the morning on an empty stomach. FOR ADULTS ONLY.

Follow These Simple Steps:

  • Determine what dose you should start with, based on the table below. Generally, the teaspoon dosage works well for most.
  • Dissolve each dose in 2 or more ounces of water (at room temperature). Allow the bubbling (effervescence) to stop before drinking.
  • Drink mixture and use log below to record the amount of Vitamin C you took and the time you took
  • Wait 15 minutes and then repeat steps 1 and 2.
  • Continue until you feel a rumbling/gurgling in your gut. If nothing happens after 4 doses, double the dose.
  • Continue dosing every 15 minutes until you achieve a watery stool or an enema-like evacuation of liquid from the rectum. Caution: DO NOT Stop at “loose”

You want to get to a full watery evacuation to energize the body to “flush out” toxins and reduce the risk that they may recirculate and cause problems.

  • After your flush, let your provider know how much Potent C Guard you had to take in order to flush.
  • In my practice, I use someone’s first C-Flush as a starting point for discussion, to recommend what I think might be your best long term dosage, as well as how often you might do the C-Flush.


C-Flush Starting Dose
If you are Start with this dose of

Potent C Guard…

…which provides this amount of

ascorbate (Vitamin C)

Healthy 1 teaspoon 3 grams of ascorbate
Moderately Healthy 1.5 teaspoon 4.5 grams
Not Healthy 2 teaspoons 6 grams

The long-term goal is to take 75% of your “flush dose” as a daily maintenance of Vitamin C.

For most people, it takes somewhere between 3-8 teaspoons of Potent C Guard to flush. This can differ for others, up to 15, 20, or more than 50 grams depending on your health status and how quickly your body uses up ascorbate (vitamin C).

Helpful Hints:

  • Drink enough water with each dose. Cramps may occur if the ascorbate is not dissolved in enough
  • Sometimes people remain bloated for the rest of the day of calibration. Occasionally, some people have loose stools for a day or so after doing the ascorbate flush.
  • Some people have reported hot stools that seem to burn the anus after several evacuations. If so, you can use a natural salve, such as calendula ointment (or a baby diaper cream), to soothe the area. This tends to cease after the first few times you do the calibration.
  • People with hemorrhoids, irritable bowel disease, or inflammatory bowel disease may need to increase ascorbate and bioflavonoids slowly over time before doing an ascorbate calibration. Speak with your healthcare provider for guidance.
  • For best results, the addition of certain important nutrients may be recommended. These may include magnesium and choline citrate, which are especially helpful if cramps occur. Fiber, healthy probiotic organisms, recycled glutamine, and methylation factors can help additionally to decrease any irritation or queasiness that may occur during the flush process. Ask your provider for more details.
  • Many people find that they feel better than they have in a very long time after the first ascorbate flush. Some report a greater sense of well-being after the second or third. The overall consensus is that as time goes on doing these calibrations helps people feel increasingly better.

I offer this as a great tool to find out your body’s need for Vitamin C, and also as a tool to clear out your colon, whether you are constipated, beginning a GI or parasite protocol, or addressing an illness.
