Health benefit of green tea

Green tea is more than just green liquid.

Many of the bioactive compounds in the tea leaves do make it into the final drink, which contains large amounts of important nutrients.

It is loaded with polyphenols like flavonoids and catechins, which function as powerful antioxidants (1).

These substances can reduce the formation of free radicals in the body, protecting cells and molecules from damage. These free radicals are known to play a role in aging and all sorts of diseases.

One of the more powerful compounds in green tea is the antioxidant Epigallocatechin Gallate (EGCG), which has been studied to treat various diseases and may be one of the main reasons green tea has such powerful medicinal properties.

Green tea also has small amounts of minerals that are important for health.

Try to choose a higher quality brand of green tea, because some of the lower quality brands can contain excessive levels of fluoride (2).

That being said, even if you choose a lower quality brand, the benefits still far outweigh any risk.

Bottom Line: Green tea is loaded with bioactive compounds that can have various beneficial effects on health.
2. Compounds in Green Tea Can Improve Brain Function and Make You Smarter


Green tea does more than just keep you awake, it can also make you smarter.

The key active ingredient is caffeine, which is a known stimulant.

It doesn’t contain as much as coffee, but enough to produce a response without causing the “jittery” effects associated with too much caffeine.

What caffeine does in the brain is to block an inhibitory neurotransmitter called Adenosine. This way, it actually increases the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine (3, 4).

Caffeine has been intensively studied before and consistently leads to improvements in various aspects of brain function, including improved mood, vigilance, reaction time and memory (5).

However… green tea contains more than just caffeine. It also has the amino acid L-theanine, which is able to cross the blood-brain barrier (6).
