Does Vitamin C boost your Immune System in a substantial way?

Does Vitamin C boost your Immune System?

One of the best methods to increase our immune system is to take care of hygiene. Equally important is to make sure we eat and drink healthy stuff, like organic produce and clean water. 
Sometimes our body demands extra, so the question is: does Vitamin C boost your immune system?

Linus Pauling is the only scientist so far that received 2 Nobel prizes in 2 different areas (Chemistry and Peace) not shared with somebody else. In 1970 he wrote Vitamin C, the Common Cold and the Flu. In this book he emphasizes the importance of Vitamin C. Grams of it.

Recommended versus Exceptional

Every country has a food agency that hands out lots of recommendations. The recommendations are based on averages. Averages of quantities they know will be sufficient. But also averages of quantities they suspect will be most followed.

In the USA for instance the recommended daily quantity for adults is 65 to 90 milligrams. The Dutch food agency recommends 70 mg. In the UK the recommended daily amount is 40 mg.
An orange contains about 50 mg. to give you some kind of comparison.

Pauling recommends 3 gr a day, that is 3000 mg!

Why would we take such huge amounts of Vitamin C?

Boost your healthy lifestyle

Pauling substantiates his recommendation by looking at world of flora and fauna. Humans are about the only living creature whose body can’t produce Vitamin C. Most animals and all plants can. We have lost that ability in ancient times.

Yet Vitamin C protects us against harmful influences like stress, air pollution and several infections.

Robert Cathcart, an orthomolecular doctor, prescribed his patients as much Vitamin C as their body could handle. He called that the principle of intestinal tolerance. You’ll get diarrhea from too much Vitamin C intake. 

By prescribing grams of the vitamin to swallow every hour, he would quickly find out how much that patient could handle. 

Will Vitamin C boost your Immune System?

According to Pauling and Cathcart Vitamin C will boost your immune system substantially. They have tested that on their patients with ample result.

Nobody knows at this moment whether Vitamin C will help in the present pandemic. But as long as you listen carefully to your body it won’t harm you to take any*. We each respond to big amounts differently. But we also respond differently during time. When we are healthy and not stressed, we need less than when we are ill or worrying. 

So increase the dose when you don’t feel too well up to the point your bowels begin to protest and maintain that dose until you feel better. 

Can’t I get enough Vitamin C by eating oranges?

Vitamin C capsules

Calculating the numbers I mentioned above, you would have to eat 60 oranges a day. Wouldn’t that be boring? And time-consuming as well. 

For a long time I wasn’t too keen on supplements. I considered them a scam and thought I was OK by eating organic, healthy food. Which is not bad at all, of course.

But my yearly medical tests and orthomolecular specialists have convinced me that at times a body needs something extra. I am a huge advocate of the adage ‘food as medicine’, but I also know by now that at times food isn’t enough.

Supplements complement food, they don’t replace it

The advantage of supplements is you can pinpoint one specific substance. The advantage of healthy food is you get a lot of different vitamins and minerals inside your body.

Along with my vitamin capsules I still eat oranges as well. Orange food has beta-carotene and potassium, that are a blessing for the way our skin looks. For my website AGE with CARE I wrote an article about the benefits of orange food.

15+, at times unexpected, Benefits of Vitamin C

Doing the research for this article I discovered a lot of advantages of Vitamin C. Most are backed by research and testing, not all. As I have stated before, it is best to keep listening to your body. And to consult trusted sources. 

In random order the benefits I found are:

  1. Supports the immune system
  2. Helps to increase dietary iron absorption
  3. Increases energy level
  4. Lowers the risk of developing a urinary tract infection
  5. May help reduce blood pressure
  6. Lowers the risk of Alzheimer’s
  7. Combats oxidative damage by free radicals (Free radicals are highly reactive molecules which, when produced in large quantities, are harmful to our body cells.)
  8. Protects skin from the sun
  9. Helps the body to repair damaged tissue
  10. Lowers the chance of developing cataracts
  11. Increases bone density
  12. Prevents muscle pain and contributes to muscle recovery after intensive sporting
  13. Improves mood and libido
  14. Improves blood circulation
  15. Reduces wrinkles and prevents skin aging
  16. Supports shiny and strong hair
  17. Improves the strength of the nails

The Key to a Healthy Immune System

The present pandemic made me aware of a couple of things. 

  • Given the fact that most of the people that died were overweight, it is clear that a healthy lifestyle is really important.
  • One of the things you can do is to increase your daily dose of Vitamin C.
  • All things are connected. 
  • To heal is important as soon as you get ill, but prevention has considerably more value.
  • It’s important to take every measure possible to prevent getting ill, but sometimes one just has bad luck. You can construct your own life only to a certain extent.

* It seems that Vitamin C supplements can have a negative effect in people with hemochromatosis, an excessive intestinal absorption of dietary iron. Vitamin C increases the absorption of iron, resulting in more stacking.

  1. Informative post, you have summed up well about the importance of Vitamin C in boosting immune system…It is a strong antioxidant that can boost your blood antioxidant levels. This may help reduce the risk of chronic diseases like heart disease.

    • Thanks so much, Satish. Living a healthy lifestyle does a lot of good for several parts of your body, doesn’t it.

  2. Loved this article! I had no idea humans were just about the only living creatures that can’t produce vitamin C. Eating 60 oranges a day would be difficult, not to mention erosive to your enamel! Thanks for this information, I learned a lot!

  3. Wonderfully insightful article. Although I would love to eat 60 oranges a day, that is probably not such a good idea. Even if you alternate it with kiwis and lemons, I still think it is way too risky. What I miss in your article is how vitamin C relates to other vitamins, minerals and ingredients of food and drinks. Perhaps you could write something about that in a future blog? That would also be most interesting.

  4. Hi Hannie, very informative post. I love oranges but couldn’t eat 60 a day 🙂 I was like you, not so keen to take supplements. I though I could get all the vitamins I needed from food. But that is not true, even if you have a very good and balanced diet, sometimes you need to get additional help from the supplements. In my case, I do not get too much sun so I need to take some Vitamins D supplement. Now I understand that it does not replace the food, it is really a supplement. Thanks for the information.

    • Thanks so much.
      You’re so right. Even with a lot of sun it’s possible there is a shortage of vitamin D, as I have found out. My GP said it’s because an older skin isn’t flexible enough anymore. 🙂

  5. Hi Hannie. I loved your content. To be honest, I didn’t even know that taking vitamin C had so many benefits to the human body. Very informative and each topic was related so well with each other. I enjoyed reading it.
    My mom has always been obsessed with the fact that taking vitamins by food is the right way without having any complications. So she made sure to make my mind to only rely on food vitamins but you are so right. We definitely can not eat so many oranges. One thing I know, I will send her your article and I know that her mindset will change too. Bonus for me so thanks for sharing.
    Can’t wait to see more articles from you 🙂

    • Thank you so much, Sindi. I understand your mom completely as I had the same thinking. And I am still convinced that eating the right food and balancing what your intake is with food should be our main focus. But especially while aging it’s important to give extra attention to possible insufficiencies. 🙂
      I would love to hear what your mother thinks of my article! <3
      Take care.
