Vitamin D3 is also known as the sunshine vitamin, as we get it from exposure to the sun. It helps to support the absorption of calcium and phosphorus, which in turn helps to keep bones strong. Vitamin D3 also helps to support the normal functioning of the immune system.

How much vitamin D3 should I take daily?

There are a few food sources of vitamin D3, including fish such as salmon and mackerel as well as egg yolks. But we often do not eat enough of these to get the amounts of Vitamin D3 we really need. We also get vitamin D3 from exposure to the sun. But it can be difficult to get sufficient exposure during the winter months or if you spend a lot of time working inside. Therefore it is recommended that you should take a daily vitamin D3 supplement. You should take one Holland & Barrett Vitamin D3 Tablet daily, preferably with a meal.

What foods support the immune system?

Fruits and vegetables can help to support the normal functioning of the immune system, thanks to their vitamin content. Citrus fruits such as grapefruits and oranges are high in vitamin C, and broccoli is packed full of vitamins and minerals, as well as containing vitamins A, C and E, fibre and antioxidants.

What does vitamin C do?

Vitamin C has a number of important functions in the body. It helps to maintain normal skin, blood vessels, bones and cartilage.

How much vitamin C should I take per day?

You can take a vitamin C dietary supplement to help top up your vitamin C levels. You can take one to four Holland & Barrett Chewable Vitamin C with Rose Hips Tablets each day, preferably with meals. These have a yummy orange flavour and you can opt to chew them, so they are perfect for anyone who does not like swallowing tablets whole.

Is zinc good for immunity?

Zinc is a nutrient which is found in cells throughout the body. It helps to support the normal functioning of the immune system, as well as supporting the production of proteins and DNA. Holland & Barrett High Strength Zinc Tablets is a high strength, daily zinc supplement, which is a great way to boost the overall levels of zinc in your body.

Which foods contain zinc?

Red meat and poultry are some of the best sources of zinc. Vegan sources of zinc include beans, nuts, whole grains and fortified breakfast cereals. If your diet is low in zinc, you can also take a dietary supplement.

Immunity is the ability of an organism to resist a toxin or infection. In humans, this means the body’s ability to prevent pathogens such as bacteria and viruses, from invading and causing harm or illness.

What is the immune system?

The immune system is made up of a number of different organs, cells and proteins within the body, which all work together to protect the body from invasion from bacteria and viruses. There are two different parts that make up the immune system. The innate immune system is the one which you are born with, and the adaptive immune system is the one which you develop as you are exposed to microbes. These two parts work together to protect you from infections and viruses.

How does the immune system work?

In humans, the immune system acts as the body’s defence against infections. It attacks germs and foreign substances, banishing them from the body.

What impacts the immune system?

Our immune system defends the body from infections and diseases. The functioning of our immune system is determined by multiple factors, including our genetic makeup, our lifestyle, our diet and the environments that we have been exposed to over the years.

How can I best strengthen my immune system?

You can support your immune system by ensuring that you are getting the right nutrients, through both your diet and by taking supplements. You can take a vitamin-specific supplement if there is one you feel that you are deficient in, or else, an all-round immune support supplement. Starpowa Triple Immune Support Vitamin Summer Fruits Flavoured Gummies contains a special formula featuring vitamin C, vitamin D3 and zinc which all help to support the normal functioning of the immune system.

What vitamins are good for the immune system?

Vitamins for the immune system include Vitamin C, vitamin D and zinc. These all help to support the normal functioning of the immune system.

Can you boost your immune system?

Certain vitamins, minerals and supplements can support the normal functioning of your immune system, but they won’t . ‘Boost’ implies that by upping your intake of supplements that contain certain vitamins and minerals, or eating certain foods, you can improve the effectiveness of your immune system above its normal threshold, which is simply not true. You will never be able to surpass its natural capability or go beyond normal expected levels.
