Vitamin C is popular because many people strongly believe that it helps prevent or fight the common cold. The common cold can indeed make life very uncomfortable, but the desperation to keep it away isn’t the only reason why a lot of people take it. A biochemist, Linus Pauling, winner of the Nobel Prize in Chemistry, helped the public make the connection between Vitamin C and the common cold. In 1971, he began to talk about high doses of Vitamin C as a way to prevent common cold. This idea was quickly rejected by the medical community, but ever since most people haven’t dropped the habit.

Vitamin C has many health benefits, from improving brain function to helping keep cancer away, so you can be forgiven for holding it dear to your heart. But the question remains, whether taking loads and loads of it is good for you. The answer is not simple. If a person frequently gets their vitamin C from foods, there may not be problems at all, but if it comes from supplements, there can be side effects, as the body does not absorb all of the vitamin C that it gets from supplements.

For instance, if you take 30–180 mg of vitamin C every day, your body will only absorb about 70–90% of it. 90 milligrams (mg) of Vit. Cis the recommended dose for adult males, while 75 mg is recommended for females. As an adult, if you take more than 2,000 mg of Vitamin C in a day, you may experience some discomfort because the excess that your body doesn’t use goes on to irritate some of your organs and can have the following reactions:

  • Nausea
  • Diarrhoea
  • Bloating
  • Abdominal discomfort

If you suspect that your Vitamin C intake is causing you some side effects, you should see your doctor immediately.
