The Truth About Vitamin C

The Truth About Vitamin C

Through my education I learnt that Vitamin C is one of two water-soluble vitamins, the other being Vitamin B. This means that your body cannot store any excess amounts consumed. This also means that it is virtually IMPOSSIBLE to overdose on these vitamins. With that being said, I’d like to bring your attention to some useful information that isn’t well known but should be regarding Vitamin C.


Health Canada’s recommended daily allowance for Vitamin C is below 100mg. This amount is enough to prevent scurvy, a deficiency typically seen in malnourished sailors in the 18th century. Health Canada endorses a daily upper limit of 2000 mg. Health Canada fails to acknowledge that there is no “real” upper limit of Vitamin C, as you will excrete the excess in your urine.

Personally, I ingest 10,000 mg of Vitamin C daily as I feel it is important. Vitamin C is used in many of the body’s necessary functions, such as:

  • Wound healing and repairing
  • Acts as an essential cofactor (helper) in enzymatic reactions such as producing hormones in
  • the adrenal glands
  • Helps maintain the health of your bones and teeth
  • Plays a role in helping your body absorb iron
  • Increases brain health as it is necessary to make certain neurotransmitters, including serotonin
  • The biggest function of Vitamin C is that it has antioxidant properties, meaning that it aids the body by blocking free radicals (uncharged molecules) from damaging the cells

Vitamin C also has anti-cancer properties:


  • Vitamin C was first suggested as a tool for cancer treatment in the 1950s
  • Cancer cells use sugar to flourish. The molecular structure of Vitamin C is similar to that of sugar
  • If sugar is not present, cancer cells will pull in Vitamin C instead
  • In the presence of oxygen, hydrogen peroxide is produced, which kills the cancer cell from the inside

Now you might be wondering if there are any negative effects to high dosing with Vitamin C. There are 2 negative side effects to high dosing, however both side effects can be avoided:

  1. Bowel intolerance – too much Vitamin C at one time can lead to diarrhea. This can be avoided by spreading out your intake throughout the day. I started by taking 500 mg every couple hours and now take 2000 mg five times a day
  2. Acidosis – Vitamin C is acidic by nature. If you already have any sort of acid reflux or dysfunction you need to be cautious when taking Vitamin C. You can avoid the acidity by getting buffered Vitamin C. Buffered Vitamin C is ascorbic acid (the chemical name for Vitamin C) mixed with a ground substance that makes it less acidic. It is a good idea in general to take Vitamin C buffered, as most things we ingest (especially processed food) are acidic by nature. Buffered Vitamin C is a powdered product, if you are not fond of taking pills the powdered option may be more appealing to you

befunky-collageOur bodies are capable of producing some vitamins but that does not include Vitamin C. This means that we must get it from supplements or foods. Foods that have high concentrations of Vitamin C include:

  • Bell peppers
  • Broccoli
  • Guava
  • Papaya
  • Orange
  • Lychee
  • Kiwi
