Understanding the Bowel Tolerance Method
The bowel tolerance method for understanding the body's vitamin C needs was discussed by orthomolecular medicine pioneer, Dr. Robert F. Cathcart. His observations suggested that when a person is under physiological stress from a disease, their body's need for vitamin C (ascorbic acid) may increase. The amount of oral ascorbic acid that can be ingested without causing diarrhea—the point of "bowel tolerance"—is seen as an indicator of this potential heightened demand. The greater the physiological stress or toxicity, the higher the amount of vitamin C the body may utilize before reaching this threshold. This principle is used to help understand the body's vitamin C status, which can potentially be greater than the Recommended Dietary Allowance (RDA).
The rationale behind this method is that the amount of vitamin C that is not absorbed by the small intestine and reaches the large intestine can lead to loose stools. When the body's vitamin C status may be low due to illness or stress, it might absorb the vitamin more efficiently, potentially preventing it from reaching the large intestine in high concentrations. Therefore, a higher tolerance is thought to indicate a greater physiological need for the antioxidant. When the body's vitamin C status is sufficient, excess vitamin C is excreted, and bowel tolerance may be reached at a lower amount.
Performing a Vitamin C Bowel Tolerance Assessment
To understand your potential bowel tolerance, some approaches suggest selecting a day when you can stay close to a bathroom. The assessment often involves using crystalline or powdered ascorbic acid dissolved in water, which some believe is more easily utilized in larger quantities than tablets.
Here is a general outline of an assessment process, but always consult a healthcare professional before starting:
- Consider an initial amount: Some methods suggest starting with a moderate amount of powdered vitamin C dissolved in water.
- Repeat at intervals: Some protocols suggest repeating the intake at regular intervals and keeping a record of the timing and amount taken.
- Observe and record: Pay attention to your body's response. The assessment continues until you might experience a loosening of stools, which some interpret as reaching bowel tolerance.
- Note the total amount: Once you experience this response, the process for that day is typically stopped. The total amount of vitamin C consumed up to that point is noted.
- Consider a potential daily intake: Some approaches suggest that a daily intake for maintenance could be a percentage of the total amount that was associated with bowel tolerance. This is intended to help maintain vitamin C levels without triggering a similar response. For example, if a certain amount was associated with tolerance, a lower percentage might be considered for daily intake.
- Consider dividing the intake: Splitting a potential daily intake into several smaller portions throughout the day is sometimes suggested to potentially optimize absorption.
Factors Potentially Affecting Your Tolerance
Individual bowel tolerance may not be static; it can potentially fluctuate based on health and stress levels. During periods of illness, the body's potential demand for vitamin C is thought to be higher, and bowel tolerance may increase accordingly. As health improves, the body's potential need may decrease, and tolerance could drop. It is suggested to potentially adjust intake based on these changes.
Here are some factors that may potentially influence bowel tolerance:
- Health status: The severity and type of health condition can potentially affect tolerance. For example, some anecdotal reports suggest that a severe infection might be associated with a significantly increased tolerance, sometimes to substantial amounts per day.
- Stress levels: Both physical and emotional stress may potentially increase the body's need for vitamin C, which could be observed through potentially higher bowel tolerance.
- Individual biochemical differences: Genetic makeup and metabolism mean that different people may have varying baseline needs and tolerances, even when healthy.
- Form of vitamin C: Buffered forms, such as sodium ascorbate, may be tolerated at potentially higher amounts than pure ascorbic acid because they are less acidic.
Comparison of Oral vs. Intravenous Vitamin C Delivery
While understanding bowel tolerance is a consideration for oral intake, it is not the only way to administer vitamin C. Intravenous (IV) administration may potentially bypass the bowel tolerance limitation entirely, allowing for significantly higher plasma concentrations of vitamin C. This is a key difference, especially in situations where potentially extremely high blood concentrations are desired.
| Feature | Oral (Bowel Tolerance Approach) | Intravenous (IV) Administration |
|---|---|---|
| Plasma Concentration | Limited by potential saturation point of intestinal absorption; often in micromolar range. | Capable of potentially achieving millimolar plasma concentrations, significantly higher than oral intake. |
| Delivery Method | Taken by mouth as powder, tablets, or capsules. | Administered directly into the bloodstream via an IV drip. |
| Absorption Rate | Potentially depends on the body's current vitamin C status and intestinal function. | Immediate and complete, bypassing the need for intestinal absorption. |
| Potential Side Effects | Mild gastrointestinal distress and loose stools if intake is above tolerance. | Generally considered well-tolerated under medical supervision, but requires professional oversight for higher amounts. |
| Convenience | Can be done with supplements. | Requires a clinic or hospital setting and professional oversight. |
| Potential Cost | Generally considered more affordable than intravenous therapy. | May be more expensive due to materials, administration, and professional fees. |
Considerations and Conclusion
The bowel tolerance approach offers a way for individuals to potentially understand their body's changing nutritional needs. By observing the gastrointestinal response, one may potentially gauge an intake level that could support the body's function during times of stress. This approach is based on the idea that the body's vitamin C requirements might increase significantly under physiological stress.
While this concept has been discussed in orthomolecular medicine, it is important to remember that it is not a substitute for professional medical advice or conventional treatments. Individuals with underlying health conditions, such as chronic kidney disease or G6PD deficiency, should exercise caution and consult a healthcare provider before considering high-amount vitamin C supplementation.
Understanding methods like the bowel tolerance approach may provide individuals with information about their potential need for this essential nutrient.

Frequently Asked Questions
What is bowel tolerance for vitamin C?
Bowel tolerance is the amount of oral vitamin C a person can consume before potentially experiencing loose stools or diarrhea. This threshold is sometimes seen as an indicator of the body's current vitamin C needs, which some believe increase during illness or stress.
Why might bowel tolerance for vitamin C increase during illness?
During times of potential infection or high stress, the body may utilize more vitamin C. This could create a higher demand, potentially causing the intestines to absorb more of the vitamin and allowing for larger amounts to be taken orally without gastrointestinal side effects.
How long might it take to reach bowel tolerance during an assessment?
For some individuals, an assessment might take a few hours. By considering taking vitamin C at intervals, a potential saturation point and subsequent bowel response might be noted within that timeframe.
Is understanding bowel tolerance safe?
When approached cautiously by healthy individuals, observing bowel tolerance is generally considered to reflect the body's response. However, it is not recommended for people with certain health conditions, like kidney disease or hemochromatosis, and should not be a substitute for consulting a healthcare professional.
What form of vitamin C is sometimes suggested for understanding bowel tolerance?
Powdered, crystalline ascorbic acid is often discussed for this purpose, as it can be easily dissolved in water. Some find buffered forms, like sodium ascorbate, potentially gentler on the stomach.
What happens after a potential bowel tolerance is noted?
Once a loose stool response is noted, the assessment for that day is typically stopped. The amount that coincided with the response is considered potentially above the body's level at that time. Some approaches then suggest considering a lower daily intake for ongoing use, divided into portions.
Can children consider the bowel tolerance approach?
While children generally utilize vitamin C, the bowel tolerance approach should be considered with caution and under the supervision of a healthcare provider, especially for infants and very young children. Any potential intake should be discussed with a medical professional.
