These are the supplements you should take for flu season

Studies have shown that increasing your intake of certain vitamins can support the immune system

Topping up your vitamin levels could protect you from colds and flu (The Independent )

As the temperatures drop, the nights draw in and offices and schools fill up after the summer break, our immune systems can take a hit.

The start of autumn is often associated with the beginning of cold and flu season, which also makes it the perfect time to think about ways we can protect ourselves from falling victim to bugs and viruses.

While there are plenty of health and wellness products, foods and supplements that claim to boost the health of the immune system, it can be hard to work out which ones will actually help keep us well. Should you take a multivitamin to stave off a cold? Or is it worth taking a supplement specifically formulated for immune health?

To cut through the noise it’s useful to take a look at studies that have shown which vitamins and nutrients our immune systems need to function at their best. Often we can meet our bodies needs through a balanced diet of nutrient-rich foods and drinks, however, certain deficiencies might mean that supplementing can top up what your body needs to fight off a cold.

The body is complex and needs all kinds of vitamins, minerals and nutrients to work optimally. Certain vitamins can help support cellular regeneration, gut health and reduce inflammation and this all helps with keeping colds and coughs at bay during the winter months.

Read on to find out which vitamins and nutrients might be worth supplementing, and which ones can help you to stay healthy during flu season.

Vitamin A for immune health

Vitamin A works twofold to support immune health. First, it supports the growth and development of immune cells, including T cells and B cells. A 2011 study found that vitamin A is essential for the development of Th2 cells and regulatory T cells, which helps control immune responses and maintain tolerance.

Vitamin A also helps maintain and protect mucosal barriers, such as the skin, respiratory tract, and gastrointestinal lining. These barriers are the first line of defence and prevent pathogen entry, so your body needs them to be healthy.

Research published in the British Journal of Nutrition found that vitamin A supports the immune system by maintaining healthy epithelial barriers and controlling inflammatory responses. Generally it’s easy to get enough Vitamin A into your diet because it’s found in foods like eggs, dairy and fish. The body also makes Vitamin A from beta-carotene – which comes from a variety of fruits and vegetables.

However, if your diet is lacking in these foods, supplementing Vitamin A – especially during peak cold and flu seasons –might be the way to go.

Vitamin C for immune health

Vitamin C is an immunity hero and it’s vital for the function of several immune cells, such as neutrophils, lymphocytes, and phagocytes. It helps these cells migrate to infection sites, kill pathogens, and clear dead cells.

One of the most well-known effects of vitamin C is its impact on the common cold. Regular vitamin C supplementation (above 200 mg per day) has been shown to reduce the duration and severity of cold symptoms. A review of 29 trials involving over 11,000 participants found that vitamin C supplementation reduced the duration of colds by 8 per cent in adults and 14 per cent in children.

The body does not produce or store vitamin C, so you need to consume it every day from your diet or supplements. This can sometimes be tricky if you’re not a fan of fruits and vegetables because Vitamin C is mainly found in foods like citrus fruits and leafy greens.

Myvitamins sources premium, bioavailable forms of Vitamin C, ensuring better absorption compared to some other supplements. The capsules are small in size and easy to digest. The coating is also designed to protect the content inside each capsule from stomach acid so that the Vitamin C can be absorbed by the gut. Each serving has a massive 1000mg of vitamin C, to help boost immune function, reduce fatigue, and protect cells from oxidative stress.

Vitamin D for immune health

Studies have shown that Vitamin D enhances the antimicrobial activity of innate immune cells by promoting the production of antimicrobial peptides. These peptides help in destroying pathogens such as bacteria, viruses and fungi.

It’s not always easy to get your daily fix of Vitamin D as it mainly comes from sun exposure, and isn’t present in many foods, so supplementing is a way to guarantee that your vitamin D levels are topped up, especially in winter.

In fact, experts have suggested that the whole of the UK is likely deficient in Vitamin D, so it’s a recommended year-round supplement, and especially important during months where very little sun exposure is expected.

Zinc and immune health

Zinc deficiency is associated with increased susceptibility to infections. A study by Prasad et al. (2008) found that zinc-deficient individuals are more prone to infections, including pneumonia, diarrhea and viral infections, due to weakened immune responses.

Supplementing with zinc has even been shown to reduce the duration and severity of common colds in controlled trials. For example, a study from 2011 found that zinc lozenges reduced the duration of cold symptoms by approximately 33 per cent.

Zinc is found in a variety of foods, including red meat, pulses, nuts and seeds and dairy products. However, a lot of people don’t get optimum levels of zinc from their diets. Some studies have shown that pregnant women and elderly men struggle the most with zinc deficiency, so it can be worth topping up your levels, especially during the colder months.

Myvitamins Zinc supplements may be affordable but there’s no compromise on quality. These tablets are highly bioavailable, ensuring efficient absorption and better results compared to other zinc supplements.

You might be wondering whether it’s worth taking each of these immunity heroes individually, or whether taking a multivitamin might be simpler. A multivitamin generally contains everything you need to for a robust immune system, but you do need to be aware of whether you need to be supplementing each ingredient in a multivit. In some cases, you might be consuming more than the recommended dose of each nutrient, so it can be worth checking with your healthcare provider.

For those seeking an all-rounder that delivers a dose of Vitamin C, D and Zinc, Myvitamins also offers a specialised Immunity capsule. Unlike a multivitamin, each capsule delivers a balanced serving of just three nutrients to help your body repair and thrive, topping up stores and protecting cells from free radicals and viruses.
