Vitamin C Bowel Tolerance Test

Vitamin C is an important diverse anti-oxidant that most people think of leading up to winter to prevent colds and flu due to its anti-microbial action, but did you know it also:

  • promotes collagen formation and strengthens connective tissue, producing stronger and healthier  skin, cartilage, capillaries, bones, and teeth
  • protects your heart
  • is good for you eye health
  • reduces the risk of cancer
  • is involved in hormone production
  • promotes good bowel health
  • supports your adrenal glands, helping you deal with stress better
  • supports healthy blood sugar levels
  • prevents asthma especially the exercised induced version.
  • reduces allergenic reactions
  • reduces the effects of ageing
  • helps heals all cells and reduces scarring

Even if you eat plenty of vitamin C rich foods such as fresh fruit and vegetables, it’s still hard to consume enough of this nutrient as most, if not all of our foods are prematurely harvested, artificially ripened and then processed.

Doing a Vitamin C Bowel tolerance test otherwise known as a Vitamin C flush saturates your body with Vitamin C.

Before you get started, choose a quiet day that you can stay home or close to a toilet. In this exercise you are going to consume as much vitamin C as your body can absorb when your bowels can’t tolerate anymore your tummy will start gurgling followed by a loose bowel movement.

The type of Vitamin C you choose to do this test with is very important. Buffered forms such as potassium ascorbate or calcium ascorbate work better than ascorbic acid. Next thing to watch out for is other ingredients in your product. Minerals such as Zinc are often added in with Vitamin C. In this test you may take anywhere from 10 times the normal dose to 100 times. Vitamin C is very safe, your body will purge what it doesn’t need, but zinc will become dangerous at such a high dose. Niacin is another one to watch, it will cause hot flushes long before the vitamin C starts affecting your bowel.

I don’t recommend attempting this procedure if you have haemochromatosis, IBS, IBD or Gilbert’s Syndrome.

Here we go!

I recommend starting on the hour or half hour to make it easier to monitor the time and amount of Vitamin C you have consumed. You need to drink plenty of water during the day. I start with 3 double doses to speed this process up. It’s most common to need 10-15g of Vitamin C to reach saturation but if you are mildly unwell this can increase to 50g or a severe flu 100g. In these circumstances, you may like to remain at double doses for the entire time.

  1. Take a 2,000mg dose of Vitamin C and record the time.
  2. In an hours time, take another 2,000mg
  3. Take your final 2,000mg dose of vitamin C.
  4. For each hour from now until you have had a watery bowel movement, take 1000mg of Vitamin C.
  5. Once your bowels have emptied, stop taking vitamin C and note how much you have consumed.
  6. Congratulations you are topped up to the max with Vitamin C.
  7. Over the next few days continue to take vitamin c but at half your bowel tolerance amount and in only 2 or 3 divided doses.  If the water bowel movements continue to drop to 2,000mg daily.

You can go back and repeat your bowel tolerance get anytime you feel you need to top up on Vitamin C. Most people find their tolerance reduces the more often they try this test.
