How To Do A “C-Flush”

Determining Your Individual Need for Vitamin C

A “C-Flush” can be used to determine your body’s need for vitamin C. This is accomplished by taking small amounts of Buffered Ascorbate every 15 minutes until you have met your body’s need for Vitamin C. We recommend our Potent C Guard, as it is the highest quality C available, fresh and free from fillers. 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.

Follow These Simple Steps:

  1. Determine what dose you should start with, based on the table below and what Dr. Binley has recommended.
  2. Dissolve each dose in 2 or more ounces of water (at room temperature). Allow the bubbling (effervescence) to stop before drinking.
  3. Drink mixture and use log below to record the amount of ascorbate you took and the time you took
  4. Wait 15 minutes and then repeat steps 1 and
  5. Continue until you feel a rumbling/gurgling in your gut. If nothing happens after 4 doses, double the dose.
  6. 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” stool. 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.
  7. At your next visit, let Dr. Binley know how much ascorbate you had to take in order to flush (or email results).

C-Flush Starting Dose

If you are Start with this dose of Buffered Ascorbate...  ...which provides this amount of ascorbate (Vitamin C)
Healthy 1/2 teaspoon 1.5 grams of ascorbate

Your first C-Flush is a starting point for discussion with Dr. Binley.

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

Dr. Binley will discuss your long-term dosage with you after your C-Flush, as well as how often you should do the C-Flush.

For most people, it takes somewhere between 3-8 teaspoons of ascorbate 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.

Helpful Hints: 

  • Drink enough water with each dose. Cramps may occur if the ascorbate is not dissolved in enough water.
  • 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 practitioner.
  • 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 us 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.
