At hundred, we believe information is power. That’s why we are committed to providing you with the best science-backed guidance for boosting your immune system. 

Welcome to week two of our seven-week immunity series, where we do a deep dive on an  immune-boosting vitamin or herb. This week we are covering the immune-boosting supplement Vitamin C. 

For week one of our seven-week immunity series, check out our article: Boost your immunity with Probiotics

What is Vitamin C?

Vitamin C, otherwise known as L-ascorbic acid, is a water-soluble vitamin with a powerful antioxidant effect. Vitamin C supports the immune system and is essential for Collagen synthesis, which is an important structural component of skin and other tissues. 

Vitamin C cannot be synthesised by the body, meaning it must be obtained through diet. The best natural sources of Vitamin C are green leafy vegetables, parsley, and berries. Eating a variety of citrus fruits and vegetables every day can help to naturally increase your Vitamin C levels.

What are the benefits of Vitamin C?

Research indicates that Vitamin C can be helpful for healing wounds, immune function, neurotransmitter synthesis, and protein metabolism. 

Vitamin C also helps stimulate Collagen production and protect against sun-induced damage. Vitamin C is well-known as an important nutrient for strong and healthy skin.

In addition, Vitamin C significantly boosts Calcium, and Iron absorption. Specifically, Vitamin C improves the absorption of nonheme iron — the form of iron present in plant-based foods. 

Why is Vitamin C good for boosting immunity?

Vitamin C is well known for its role in boosting and supporting a resilient immune function. Did you also know that taking Vitamin C is one of the best natural ways to reduce the severity and duration of the common cold?

Although Vitamin C doesn’t prevent you from catching a cold, adding it to your daily routine when your immune system is more vulnerable may speed up your recovery time. Studies have shown that a supplemental dose of Vitamin C was enough to reduce the duration of colds by 8% in adults and 14% in children. 

Vitamin C is a powerful antioxidant, meaning it mitigates the damaging effects of free radicals which cause oxidative stress in the body — a leading factor in disease. 

Vitamin C

Vitamin C appears to be especially beneficial to athletes and those who are physically active. Some research has proven that supplemental Vitamin C halved the number of colds in physically active people.

It is believed that athletes’ immune systems are especially vulnerable for up to 9 hours directly following an acute period of physical activity. This short-term suppression of the immune response following exercise is known as the “open window” phenomenon.

The “open window” phenomenon has been linked to upper respiratory illnesses in professional athletes. It has been proven that even a low dose of Vitamin C (150 to 200mg/ day) is able to reduce the incidence and duration of respiratory infections.

Can you take too much Vitamin C?

Just how much Vitamin C do you really need? Vitamin C is generally well-tolerated and safe in healthy individuals. However, if you take too much it is possible to experience mild side effects like diarrhoea, nausea, or stomach cramps. 

The tolerable upper limit for Vitamin C for adults is 2000mg which is roughly the equivalent of 29 oranges. Many vitamin brands overdose their Vitamin C, so always make sure you read the labels. Our 250mg Vitamin C dosage is perfect for daily supplementation to provide that extra immune boost. 

Moreover, many brands synthetically produce their Vitamin C. We extract our Vitamin C from 100% all natural rosehip which has one of the highest natural concentrations of Vitamin C.

Is it true that Vitamin C is being used to treat patients with COVID-19? 

According to Harvard Medical School, there are currently studies underway in China to determine whether high-dose intravenous Vitamin C may be beneficial for patients with severe COVID-19. The results of these studies are expected in the fall. 

There is a strong precedent for the use of high-dose intravenous Vitamin C in the treatment of serious infections and viruses. It has yielded some positive results in the treatment of sepsis as well as ARDS (acute respiratory distress syndrome). 

This is promising given that sepsis and ARDS are the most common causes of admission to intensive care, and death among those with severe cases of COVID-19. Whether high-dose intravenous Vitamin C therapy is helpful in the prevention or treatment of COVID-19 specifically, however, remains to be seen. Social distancing remains the most effective way of fighting against COVID-19.
