Does Green Tea Boost Your Immune System?

Does green tea provide protection against certain viruses? This is a question we get asked a lot lately. Well, the answer is complicated. We found this article particularly helpful in answering that question.  For your convenience we’ve added some excerpts for below. The article was written by Amber Charles Alexis, MSPH, RDN on 4/6/2022 and Medically reviewed by Katherine Marengo LDN, RDN.

 

 

Green tea (Camellia sinensis) is one of the most popular health beverages around the world.

Originating from China, green tea is lauded for many health benefits due to its potential antioxidant, antiviral and immune-boosting properties (1Trusted Source2Trusted Source).

It’s recently been investigated for a possible role in managing the Sars Covid-2 , virus which causes illness. You may have heard that drinking green tea prevents or cures the disease.”

The article further explains whether green tea effects corona virus and offers some tips to improve your immune system.

Does green tea prevent or cure Corona Virus?

Green tea is rich in health-promoting polyphenols, such as epigallocatechin-3-gallate (EGCG), which has anti-viral effects against single-stranded RNA (ssRNA) viruses like Zika, hepatitis C, influenza (flu), dengue, and others (1Trusted Source3Trusted Source4Trusted Source5Trusted Source).

These lke the corona virus is an ssRNA virus. Thus, green tea extracts continue to be investigated for their potential role in treating this virus and managing the pandemic (1Trusted Source2Trusted Source).”

Test-tube research shows that green tea extracts may combat the Sars Covid-2 virus by damaging the spike protein, preventing its entry into human cells and reducing the overall volume of the virus (3Trusted Source4Trusted Source5Trusted Source6Trusted Source).

Treatment of the test tube cells with EGCG was most effective during early stages of infection (3Trusted Source).

However, it’s important to understand that drinkingreen tea itself can’t prevent or cure any virus. Most studies showing an effect used single green tea extracts like EGCG in concentrated amounts much higher than what’s found in the natural tea.

Nonetheless, green tea extracts may have potential to be used for natural treatment of viruses after further human research and testing.

Remember, the best way to prevent serious illness from any virus is by getting vaccinated, maintaining physical distancing, and washing your hands often.

Are there benefits to drinking green tea if you have a viral infection?

An infectioncan cause inflammation, which is linked to symptoms like fatigue, muscle pain, and achy joints (7Trusted Source).

Green tea may have anti-inflammatory properties. It’s shown to reduce damaging inflammation associated with the sars covid-2 virus, potentially easing these symptoms (8Trusted Source).

The EGCG found in green tea may also shorten infection periods by suppressing viral activity, although this effect has only been observed in test-tube studies. We need human research before we can draw conclusions (9Trusted Source).

Green tea is also a source of other immune-supportive nutrients like zinc, iron, and selenium, albeit in small amounts (10Trusted Source).

Regardless, you may find that sipping on a warm cup of green tea during your… infection is simply soothing.

Green tea and immune health

Green tea contains small amounts of the following immune-boosting micronutrients (10Trusted Source):

  • Zinc: may reduce harmful reactive oxygen species caused by infections
  • Seleniumstimulates the immune system to combat infections
  • Copper: enhances activity of the body’s natural killer cells
  • Vitamin B2: enhances antibody function against viral infections
  • Vitamin B12increases the production of immune cells

Nutrient deficiencies impair immune health. For instance, research suggests that selenium deficiency may contribute to more severe illness (11Trusted Source).”

Green tea infusions made by steeping dried green tea leaves or a tea bag in hot water contain varying levels of these micronutrients, depending on the quality of soil it was grown in (10Trusted Source).

Overall, concentrations of micronutrients in green tea appear low.

Summary

Green tea contains small amounts of the micronutrients zinc, copper, selenium, and vitamins B2 and B12, all of which are shown to boost immune health.”

Immune-boosting tips

Green tea contains only small amounts of immune-boosting micronutrients. Enjoy infused green tea along with these tips to better support your overall immune health:

Summary

Increase fruit and vegetable intake, exercise regularly, avoid smoking, practice handwashing and hand hygiene, and aim for 7-9 hours per night to boost your immune health.

The bottom line

Green tea is a popular drink often touted as a health beverage. Some claims may hold true: it has proven antiviral effects against single-stranded RNA (ssRNA) viruses like Zika, hepatitis C, influenza, and dengue.

Its potential role in combating viruses continues to be investigated, but drinking green tea is not yet proven to prevent or cure [any virus].”

Vaccination in conjunction with physical distancing and masking when appropriate, remains the best way to protect yourself and others from severe illness.

There are many studies that suggests that green tea can help to boost your immune system, and in this post, we explore why and how green tea may help to prevent and/or recover from viral infections

As the green tea with the highest antioxidant content on the market today (including Morning Matcha) it stands to reason that with the highest EGCG content too and retaining more vitamins and minerals from the camelia sensis plant (tea plant), then if any green tea can help to boost your immune system, then the best green tea to put to the test is our high antioxidant organic green tea.
