Supplement to boost your immunities against Covid-19

We all heard about the development of vaccination to stop the spread of COVID, but did you know there are actual scientific studies through nutrition to help fight the virus. Base on the latest stats, COVID is most lethal against elderly 70 years old and older, with pre existing condition. Studies has also found that in China, the epicenter of the outbreak, the are 86% more undocumented cases of COVID, where those population asymptomatic.

While it does not affect everyone, we don’t want to bare the responsibility of passing to those who are vulnerable. Below are some tips that may help to prevent  COVID that are under report in the media.

Evidence that lack of vitamin D is linked to COVID-19 severity

New European research has added to the growing body of evidence which suggests that a vitamin D deficiency could be linked with developing a more severe case of COVID-19. 

As Professor Jon Rhodes from the British Medical Journal  explain, “Vitamin D is an unusual vitamin — it is a hormone and we get most of it by the action of ultraviolet light on cholesterol in the skin. Unless you live in a sunny country or eat a very large amount of oily fish you are quite likely to need supplements to maintain a normal level.”

Nearly all immune cells have vitamin D receptors, showing vitamin D interacts with the immune system. A recent meta-analysis brought together results from 25 trials with more than 10,000 participants who were randomised to receive vitamin D or a placebo.

It found vitamin D supplementation reduced the risk of acute respiratory infections, but only when it was given daily or weekly, rather than in a large single dose.

One small study from the United States and another study from Asia found a strong correlation between low vitamin D status and severe infection with COVID-19. 

SUMMARY  Vitamin D is essential for immune function. Healthy levels of this vitamin may help lower your risk of respiratory infections.

Bird Nest to boost immune system

While it is not a cure, according to a study by NCBI, bird nest is proven to boost the immune system.

In 2006,  research was also conducted to study the antiviral efficacy of natural cave and house-cultured bird nest. The research demonstrated that bird nest extract could effectively inhibit influenza infection independent of its strains− human, avian and swine, by directly binding to the influenza virus itself or inhibiting the hemagglutination of the virus to human erythrocytes. In other words, it is a safe and valid natural source for the prevention of influenza viruses.

As mentioned, EBN hasn’t been proven to be the cure for COVID-19, however, consuming it helps to build up and boost the body’s immune system against influenza strains, which is helpful to fight against these coronaviruses. As the saying goes, prevention is always better than cure.

Zinc Supplement

Zinc is a mineral that’s commonly added to supplements and other healthcare products like lozenges that are meant to boost your immune system. This is because zinc is essential for immune system function.

Zinc is needed for immune cell development and communication and plays an important role in inflammatory response.

Studies has found that deficiency in this nutrient significantly affects your immune system’s ability to function properly, resulting in an increased risk of infection and disease, including pneumonia (9Trusted Source10Trusted Source).

Zinc deficiency affects around 2 billion people worldwide and is very common in older adults. In fact, up to 30% of older adults are considered deficient in this nutrient (11Trusted Source).

Numerous studies reveal that zinc supplements may protect against respiratory tract infections like the common cold (12Trusted Source13Trusted Source).

It is also beneficial for those who are already sick.

In a 2019 study in 64 hospitalized children with acute lower respiratory tract infections (ALRIs), taking 30 mg of zinc per day decreased the total duration of infection and the duration of the hospital stay by an average of 2 days, compared with a placebo group (14Trusted Source).

Supplemental zinc may also help reduce the duration of the common cold (15Trusted Source).

Taking zinc long term is usually safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc (9Trusted Source)Trusted Source.

Take not excessive doses may interfere with copper absorption, which could increase your infection risk.
