What Does Vitamin C Do For The Immune System

How Does It Affect Immunity

Does Vitamin C Really Help With Immunity Amid Pandemic?

Vitamin C affects your immune health in several ways. Its antioxidant activity can decrease inflammation, which may help improve your immune function .

Vitamin C also keeps your skin healthy by boosting collagen production, helping the skin serve as a functional barrier to keep harmful compounds from entering your body. Vitamin C in the skin can also promote wound healing .

The vitamin also boosts the activity of phagocytes, immune cells that can swallow harmful bacteria and other particles .

In addition, it promotes the growth and spread of lymphocytes, a type of immune cell that increases your circulating antibodies, proteins that can attack foreign or harmful substances in your blood .

In studies of its effectiveness against viruses that cause the common cold, vitamin C doesnt appear to make you any less likely to get a cold but it may help you get over a cold faster and make the symptoms less severe .

Theres also some evidence from animal research and case studies in humans that high dose or IV vitamin C can reduce lung inflammation in severe respiratory illnesses caused by H1N1 or other viruses .

However, these doses were far above the DV, and theres not enough research to support the use of high dose vitamin C for lung inflammation at this time. You shouldnt take high doses of vitamin C supplements even orally because they can cause side effects like diarrhea .

Can A Vitamin C Supplement Really Keep You From Getting Sick

Despite it’s popularity as a remedy for the common cold, there’s actually no evidence to suggest that a large dose of vitamin C can actually prevent one or any other type of illness, for that matter.

And while you may have heard that a large dose of vitamin C can slightly reduce the duration of a cold, this only applies if you take that large dose every singleday of the year even when you’re not sick. This means that if you rip that vitamin C packet open after your symptoms begin, there’s no evidence to suggest it’ll actually shorten the length of your cold.

As it turns out, boosting your immune system is more complicated than just downing a packet or a pill. And while vitamin C does play an important role in supporting your immune system, it doesn’t take megadoses like the ones found in supplements which often contain 1667% more vitamin C than you actually need every day.

Barrier Integrity And Wound Healing

The skin has numerous essential functions, the primary of which is to act as a barrier against external insults, including pathogens. The epidermal layer is highly cellular, comprising primarily keratinocytes, whilst the dermal layer comprises fibroblasts which secrete collagen fibers, the major component of the dermis . Skin contains millimolar concentrations of vitamin C, with higher levels found in the epidermis than the dermis . Vitamin C is actively accumulated into the epidermal and dermal cells via the two sodium-dependent vitamin C transporter isoforms 1 and 2 , suggesting that the vitamin has crucial functions within the skin. Clues to the role of vitamin C in the skin come from the symptoms of the vitamin C deficiency disease scurvy, which is characterized by bleeding gums, bruising, and impaired wound healing . These symptoms are thought to be a result of the role of vitamin C as a co-factor for the prolyl and lysyl hydroxylase enzymes that stabilize the tertiary structure of collagen . Further research has shown that vitamin C can also increase collagen gene expression in fibroblasts .

Studies have shown that vitamin C may help lower blood pressure in both those with and without high blood pressure.

An animal study found that taking a vitamin C supplement helped relax the blood vessels that carry blood from the heart, which helped reduce blood pressure levels .

Moreover, an analysis of 29 human studies found that taking a vitamin C supplement reduced systolic blood pressure by 3.8 mmHg and diastolic blood pressure by 1.5 mmHg, on average, in healthy adults.

In adults with high blood pressure, vitamin C supplements reduced systolic blood pressure by 4.9 mmHg and diastolic blood pressure by 1.7 mmHg, on average .

Hence the virus hits the lungs more commonly in adults and it is less seen in children which have less ACE receptors. Zinc is a sort of a plug that blocks this gateway for the Coronavirus. Newer studies are also showing that zinc can block the enzyme that is responsible for replication of the coronavirus genetic code also known as ribonucleic acid .

Vitamin C Helps To Lower The Chances Of Catching A Cold

A balanced vitamin C level contributes to the healthy function of the immune system. Once the cold viruses have reached our mucous membranes, vitamin C becomes active in various places. It induces the formation of white blood cells, adheres to free radicals, neutralizing them and regenerating more of the body’s own antioxidants. In this way, it keeps our immune system going and reduces oxidative stress. When a cold starts, the vitamin C level occasionally falls drastically owing to the increased expenditure. If this happens, it is advisable to take high doses of vitamin C quickly to support our bodys defense system that it is not brought down to its knees.

As little as two glasses of freshly squeezed orange juice a day help us to have a healthy immune system. This was shown by some studies, in which a balanced vitamin C level could shorten the duration of a cold somewhat and alleviated symptoms. If you notice the first signs of a cold, it is therefore a good idea to fill up the vitamin C reservoir immediately and not to give up until you have hopefully recovered quickly from the cold.

Do Low Histamine Diets Help Recovery From Long Covid

There are a number of diets and eating patterns popular within the long COVID community. One is to follow a low histamine diet, which is supposed to reduce the ongoing inflammation that is thought to be a key cause of long COVID symptoms.

While our nutrition research shows that certain eating patterns are linked to inflammation, there isnât strong evidence showing that low histamine diets can combat inflammation in long COVID. But in the absence of robust studies about the best nutrition for long COVID, itâs understandable that people might want to give it a try.

Registered dietitian Elaine Anderson has written about low histamine diets for long COVID and warns:

âA low histamine diet can be restrictive and time-consuming. Feedback from the long COVID support groups suggest that many have tried the diet but found it difficult to follow combined with their debilitating symptoms. There are also many food lists available on the internet and many have conflicting advice.â

Its Antioxidant Properties Help Guard Against Chronic Disease

Can Vitamin C Boost Immunity?

Many of the benefits of vitamin C can be traced to its antioxidant properties. Antioxidants act to neutralize free radicals, which are volatile and harmful substances produced in the body that cause damage to cells and tissues, Samuels says. According to the Mayo Clinic, antioxidants can protect against the development of serious health conditions, such as cancer or heart disease. More studies especially ones involving human participants are needed, however, to show whether vitamin C specifically can prevent cancer or cardiovascular disease, per Harvard T.H. Chan School of Public Health.
