But why is Vitamin C so praised anyway? Let's figure out a few myths and truths about this magical micronutrient.


Vitamin C is an essential for:

  • The maintenance of skin, blood vessels, bones and cartilage

  • Wound healing

  • Protecting against oxidative stress and a number of diseases

  • Helping to support the immune system (alongside Zinc and Vitamin A)

Myth: Mega-dose of Vitamin C is an ultimate flu remedy

During the colder weather people load up on OJ and vitamin C supplements to avoid getting sick.

While some research shows that people who regularly take vitamin C supplements may have slightly shorter colds or somewhat milder symptoms, for most people, boosting vitamin C doesn't reduce the risk of catching the common cold. Several of the reviewed studies included people under intense physical stress, including marathon runners and soldiers training in the Arctic. Among these individuals, those who took vitamin C were about half as likely to catch a cold as those who did not take such supplements. But in the general population, the supplements did not prevent the common cold.

It is true that vitamin C is critical for immune function, and that it plays a key role in wound healing. But the best way to keep your immune system strong is to eat healthfully, including vitamin C-rich produce, all the time.

Myth: Vitamin C will boost immune system against coronavirus

Unfortunately, there is no evidence that Covid-19 can be treated with Vitamin C. However, it definitely wouldn't hurt!

No evidence suggests that Vitamin C supplements can help prevent Covid-19. To boost immune system people need to regularly eat healthy balanced food (Hire The Jar Healthy Vending machines to help with that in any workplace), exercise, and manage stress. Then only body will be slightly more resistant to any viruses, including seasonal flues.

However, some preliminary evidence suggests that certain common dietary supplements still help. One of the most promising immune strengthening mineral is not Vitamins C, but zinc which is medically proven to be helpful in terms of curing the symptoms of common cold viruses, as well as even a coronavirus.

Myth: Lemons and oranges are the top source of Vitamin C

Orange juice to the rescue!

Might be a little boring myth, because everyone know that lemons are far from being the top source for Vitamin C.

High vitamin C foods include guavas, bell peppers, kiwifruit, strawberries, oranges, papayas, broccoli, tomatoes, kale, and snow peas if we consider that the current daily value (% DV) for vitamin C is 90mg.

For comparison oranges have only 53 mg of Vitamin C per 100 gr, while Broccoli have 89 mg per 100 gr.

Stay healthy with The Jar!
