Research has identified EGCG as the most active agent in Green Tea. Green Tea is a unique formula in that it contains the highest percentage of EGCG currently in the market. EGCG supports liver health as well as detoxification and elimination functions.

Green Tea may increase the activity of antioxidants and detoxifying enzymes within the small intestine, liver and lungs. EGCG helps to support cholesterol levels within normal ranges and balances the ratios of HDL and LDL cholesterol.

Research has shown that EGCG supports the activity of immune cells, and numerous studies have demonstrated the ability of EGCG to prevent the proliferation and growth of virus cells. EGCG is shown to support skin health by recycling aged cells and supporting new cell growth. EGCG may also support metabolism due to its thermogenic effect and helps to maintain normal blood insulin levels.

EGCG supports the burning of fats and helps control appetite, which helps to support weight loss and weight management. So drink up! And if immune health is your top concern, you might want to start with this list of the top teas for a healthy immune system, in order from strongest evidence to weakest.

Mild, bittersweet green tea is a rich source of catechins. Epigallocatechin gallate EGCG is one of the most abundant and best-known catechins in green tea.

It also offers perks for your immune system. For example, a past study found that treating mice with EGCG increased the number of regulatory T cells in their spleens and lymph nodes. Regulatory T cells modulate immune response, helping your system stay balanced and preventing it from attacking healthy cells.

Research suggests EGCG may also affect immune function in humans. They discovered that the EGCG prevented the T cells from creating pro-inflammatory proteins known as cytokines, which suggests that the plant compounds in green tea may help regulate the immune system.

While these results offer clues about the link between green tea and immunity, more research in humans, people with weakened immune systems, and larger population sizes are needed to know for sure. It turns out that turmeric , the yellow orange spice that gives curry its bold color, may also be a boon to your immune system when enjoyed in tea.

The primary active compound in turmeric is curcumin. According to a review published October in Foods , curcumin effectively scavenges different types of free radicals, controls enzymes that neutralize free radicals, and helps prevent the creation of free radicals.

Given the role that free radical damage can play in many diseases, the antioxidants in turmeric may make this spice a handy addition to your immune-health diet. Researchers have also found that curcumin may play an important role in the immune response. For example, a past study using cultured spleen cells from mice revealed that curcumin could regulate T cells and B cells, two lymphocytes that recognize and respond to foreign substances inside your body.

In the aforementioned study, curcumin helped regulate the immune response to prevent immune cells from attacking healthy tissues. Researchers concluded that curcumin may be a promising therapy for keeping the immune system in check.

This dark, bold tea variety gets its dark color from a group of polyphenols known as theaflavins. Yet the antioxidants in black tea may have unique effects on the immune system. For example, a past clinical trial found that healthy people defined in this case as having no major illnesses and normal to mildly elevated systolic blood pressure who drank three cups of black tea per day for six months showed increased immune activity.

Researchers looked at three markers that indicate your immune system has kicked into gear: neopterin, kynurenine, and tryptophan. While black tea had no significant effect on neopterin or tryptophan levels, it did increase kynurenine, which suggests that the polyphenols in black tea help activate the immune response in healthy people.

The fact that this study had human subjects drink black tea is a plus. But the sample size was small — 45 people drank the tea and 49 were in the control group.

To better understand the effect of drinking tea on specific health conditions and the immune system, more studies would be needed with a variety of different patients and, ideally, larger sample sizes.

Thanks to minimal processing, white tea is one of the lightest, most delicately flavored varieties on the market. Like its green cousin, white tea offers high levels of catechins, according to a past review.

Indeed, previous research suggests that white tea has antioxidant benefits similar to green tea, though the antioxidant potential of green tea is still greater, Lee notes. Robust human research on white tea and immunity is lacking, which is why this variety is lower on this list.

Yet the minimal evidence we have so far suggests it may be worth a closer look in future literature. For example, a past test-tube study found that white tea extract helped protect rat nerve cells against damage when exposed to hydrogen peroxide, a free radical.

And another test-tube study found that white tea extract helped tame inflammation in human skin cells caused by free radicals. As an added perk, white tea may offer antimicrobial benefits.

For example, researchers tested the antimicrobial effects of white tea leaf by pitting it against oral Streptococcus mutans and Streptococcus sobrinus bacteria, two microorganisms that contribute to tooth decay. After a hour incubation period, researchers found that the white tea extracts showed significant antibacterial effects against Streptococcus mutans , which suggests that white tea extract may help protect against tooth decay.

The findings were published in August in Materials Today: Proceedings.

In some studies, EGCG injections significantly improved inflammation, as well as recovery and regeneration of neural cells in mice with spinal cord injuries 13 , However, the available data is inconsistent More research is needed to better understand whether EGCG may effectively prevent or treat degenerative brain diseases in humans.

EGCG in green tea may offer a variety of health benefits, such as reduced inflammation, weight loss, and the prevention of heart and brain diseases.

Still, more research on its effectiveness is needed. The reason for this is not completely understood, but it may be related to the fact that a lot of EGCG bypasses the small intestine too quickly and ends up being degraded by bacteria in the large intestine A single cup 8 ounces or ml of brewed green tea typically contains about 50— mg of EGCG.

Dosages used in scientific studies are often much higher, but exact amounts have been inconsistent 11 , Daily intakes equal to or above mg of EGCG per day increases the blood levels of transaminases, an indicator of liver damage One group of researchers suggested a safe intake level of mg of EGCG per day when ingested in solid supplemental form In fact, EGCG supplements have been associated with serious side effects, such as 16 :.

EGCG may also interfere with the absorption of some prescription medications, including certain types of cholesterol-lowering and antipsychotic drugs To ensure safety, always consult with your healthcare provider prior to starting a new dietary supplement.

There is currently no clear dosage recommendation for EGCG, though mg daily for up to 4 weeks has been used safely in studies. EGCG supplements have been linked to serious side effects and may interfere with medication absorption.

EGCG is a powerful compound that may benefit health by reducing inflammation , aiding weight loss, and preventing certain chronic diseases.

When taken as a supplement, EGCG has occasionally been associated with serious side effects. The safest route is to consult with your healthcare provider prior to adding EGCG to your routine to ensure this supplement is right for you.
