Boost Your Immune System
Your immune system is vital for preventing and fighting off diseases. This is especially important with the current coronavirus pandemic.
The right diet will provide the nutrients and vitamins that your immune system needs to stay in tip top condition and work hard for you.
You now know that your immune system is a complex mixture of cells, chemicals and processes that work together to provide you with protection against antigens. It is very important that you do all that you can to boost and maintain your immune system levels so that you can prevent diseases.
We encourage you to follow the advice in the last couple of chapters by avoiding things that can damage your immune system and eating the foods that will boost it. In this chapter we will look at using supplements to provide your immune system with a healthy boost.
While we recommend that you take the advice in this chapter seriously and chose the right
supplements, please be aware that the taking of supplements is not guaranteed to prevent diseases and will be very unlikely to cure any diseases that you may currently have.
We will provide you information on supplements here that can bolster your immune system that is based on sound research.
Vitamin D
Vitamin D is one of the most essential nutrients for the proper functioning and overall health of your immune system. It is a fat soluble that increases the fighting abilities of macrophages and monocytes that make up your white blood cells.
Most people just do not get enough vitamin D. When you are deficient in this vitamin it is possible that it can have a negative impact on your immune system. A low level of vitamin D can put you more at risk to respiratory infections like the coronavirus and the flu.
A number of studies showed that using vitamin D supplements can improve the response of the immune system. Some recent research suggested that vitamin D supplements may provide additional protection against respiratory infections.
A review of studies of over 11,000 people in 2019 revealed that using vitamin D supplements significantly lowered the risk of a respiratory infection in people that were deficient, and also lowered the risk of infection in others that had adequate levels of vitamin D.
Vitamin C
A lot of people take vitamin C supplements because they know that is good for their immune system.
Vitamin C provides support to immune cell functionality and enhances the ability of these cells to fight off antigens.
Vitamin C also plays an important role in the death of cells. This is vital because the dead cells need clearing out and replacing with new cells so that your immune system can remain healthy. It is also a powerful antioxidant and will help to prevent damage due to oxidative stress.
A big review of a number of case studies involving over 11,000 participants found that by taking vitamin C supplements regularly, adults were able to reduce the duration of the common cold by 8% and children by 14%.
Zinc
Zinc is a mineral that is critical for the healthy functioning of your immune system. Many supplements contain zinc because it is so vital for the development of immune cells and for the response to inflammation.
You really do not want to be zinc deficient because this could certainly compromise your immune system. But more than 2 billion people across the world have a zinc deficiency and this is especially prevalent in older people.
There have been many studies showing that taking zinc supplements can protect against respiratory infections. It can also help those that are sick already. A study in 2019 of over 60 children in hospital
with a respiratory infection found that supplementing zinc intake by a further 30 mg each day reduced their duration of stay by 2 days on average.
Selenium
Being a powerful antioxidant, selenium plays a crucial role in the health of your immune system. It is also an essential mineral for your overall health and wellbeing. As an adult you need to have a daily selenium intake of 55 micrograms per day.
There have been various studies that show viruses thriving in people that are selenium and vitamin E deficient. By taking selenium supplements, there is a good chance that you will provide your immune system with a boost and also minimize inflammation.
Black Elderberry
The treatment of infections using black elderberry has been practiced for a long time. Various test tube studies revealed that elderberry extract contains potent antiviral and antibacterial properties to fight against pathogens (antigens) which can cause respiratory infections. Studies also showed it to enhance the response of the immune system and reduce severity and duration of colds.
A recent review of four studies with 180 participants found that elderberry supplements reduced upper respiratory symptoms resulting from viral infections significantly. You can obtain elderberry supplements in both capsule and liquid form.
