Restore normal immune function with supplements designed for the whole family

It's hard to stay healthy throughout the year, but winter increases your risk for colds, coughs and other infections. Protecting your immune system should be a priority, and if you have children, you'll know all too well how easily they can pick things up.

You can eat numerous foods to improve your immune system, but hectic lifestyles and constant work and family commitments mean many people fail to give their bodies enough vital nutrients.

If you struggle to get your daily intake through diet alone, we offer natural supplements packed with antioxidants and vitamins. You can boost your immune system and keep yourself - and the family - healthy.

Why protecting your immune system function is essential

The human immune system has numerous organs, tissues and cells. They all unite to protect the body against infections and diseases. When our immune system functions properly, it can recognise foreign invaders, like viruses and bacteria, and mount a response to eliminate them from the body.

However, many things can weaken our immune system, making us more susceptible to getting sick. These include:

  • Poor nutrition
  • Lack of sleep
  • Excessive stress
  • Smoking
  • Excessive alcohol consumption

If the immune system doesn't function correctly, it can lead to all sorts of problems. Here are just some of them.

You may get sick more often.

People with lower immune systems might get sick more than those with normal functioning systems. As the body needs immunity to fight off upper respiratory tract infections, people can get sick more often and take ages to recover from general colds and other illnesses.

The symptoms might be more severe.

Not only may you get sick more often if you have a low immune system, but you may also experience more severe symptoms when you do get sick. This is because your body cannot fight the infection effectively, leading to a more severe illness.

Low immune systems often mean a simple cold or influenza-type infections can become severe, leading to illnesses like pneumonia and sepsis. These infections can be life-threatening, so it is vital to see a doctor if you think you may be at risk.

Longer recovery times after surgery.

If you have surgery, your immune system plays an important role in helping you recover. A low immune system can make it harder for your body to heal after surgery, and you may be at risk for complications.

You may need to take special precautions.

Some people with low immune systems might need precautions to avoid getting sick. For example, if you have a poor immune system and are around someone with a sore throat, that could become a more severe infection.

Sealions offer a range of essential vitamins to support normal function of the immune system

While all vitamins and minerals can help support your immune system, certain vitamins perform better than others. These supplements have many benefits and can help your body fight infections or create a shield to prevent them in the first place.

Vitamin C

Vitamin C helps to protect the body against infection by boosting the production of white blood cells, which are crucial to fighting off illness. It also helps to increase interferon production, a protein that helps defend the body against viral infections.

The antioxidant is a powerful addition to any diet and can protect cells from damage caused by free radicals. Studies have show that people who take vitamin C supplements regularly tend to get sick less often than those who do not, and also that they recover from illness more quickly (NCBI).

Vitamin D3

Also known as the sunshine vitamin, vitamin D3 is an essential nutrient that helps the body absorb calcium, which is needed for normal bones and healthy teeth. However, vitamin D3 also plays a vital role in the immune system.

It helps to regulate the production of white blood cells, which are responsible for fighting infection, but also can reduce inflammation, preventing a wide range of ailments.

Iron

Iron is highly regarded for its ability to transport oxygen in the blood, which supports a healthy immune system. Studies have shown that iron deficiency can weaken the immune system, making individuals more susceptible to infection (MRC).

Calcium

Calcium is necessary for the proper development and function of immune cells and helps regulate the inflammatory response. Also, calcium helps activate natural killer cells, which are crucial in destroying viruses and bacteria.

Furthermore, calcium deficiency has been linked to an increased susceptibility to infection. As a result, calcium is an important nutrient for supporting immune system function.

Zinc

Zinc is an essential trace element that plays a vital role in many aspects of human health. It contributes to cell growth and division, hormone production, and the metabolism of carbohydrates and proteins.

Children are particularly susceptible to zinc deficiencies, so taking it can support immunity and assure normal growth. While you can find zinc in various foods, including meats, shellfish, nuts and grains, you can also get it in supplement form.

Multivitamins

Vitamins and minerals are essential nutrients that the body needs to function correctly. They help to support many different bodily processes, including the immune response. A multivitamin can benefit your health and support the immune system if you're not a fan of taking loads of tablets each day.

While a balanced diet can benefit the immune system, a daily multivitamin can give you some much-needed support.

When you buy supplements from Sealions, you get to be a part of a movement

We set up our business because we know that vitamin providers are often charging ridiculous amounts to customers. Keeping your body healthy shouldn't require a significant investment - but unfortunately, with some suppliers it does.

Sealions is not just the answer to a question, but also a solution that raises many other questions;

Why didn't other suppliers do this before? What makes them charge so much? It's not acceptable, and our service aims to stop it.

Here's what you get when you choose Sealions.

Incredible savings on all of our supplements

We aim to provide the highest quality vitamins and minerals for your immune system at the lowest prices. Typically, a 365-day supply of our vitamins cost as little as £5.00, but with our regular promotions, you can sometimes support your immune system for much less.

We take our commitments seriously

Everyone deserves to enjoy normal immune function, but it's important to remember that the human action can damage the planet's immune system. Many potential issues arise from pollution, including the impact single use plastics have on our oceans.

We go out of our way to protect the environment where we can, including using compostable packaging.
