How Green Tea Flows Through Our Body

At TEATUNE, we believe tea is a soft melody that plays through our body, tuning each system into balance. Especially green tea. Its story is one of ancient purity and modern wellness, working quietly yet powerfully — from the first sip to the final breath.

Why Green Tea?
Though it shares roots with black tea, green tea dances to a different tune — less oxidised, more alive. Its vivid green leaves retain more of the plant’s original compounds, which is why wellness lovers have cherished it for centuries.

What’s Inside a Cup of Green Tea?

Think of it as a trio in perfect harmony:

• Catechins (especially EGCG): Powerful antioxidants that protect our cells and rev up metabolism
• Caffeine: Gentle stimulation that lifts, without jitters
• L-Theanine: The calm that sharpens focus — like background music for our brain

The Journey: How Green Tea Flows Through Us

Let’s follow a cup of TEATUNE green tea — from our first sip to its final ripple through our body:

Time	Where	What’s Happening
0–5 sec	Mouth	Catechins awaken umami sensors; saliva is stimulated; fluoride begins to protect our teeth.
5–10 sec	Esophagus	A smooth passage — always sip below 60°C to avoid irritation (World Health Organization, 2016).
10 sec–30 min	Stomach	Caffeine starts absorbing (~20%); catechins begin breaking down.
30 min–2 hrs	Small Intestine	90% of caffeine absorbed into bloodstream; L-theanine reaches the brain; EGCG binds bile acids, boosting antioxidant activity.
1–3 hrs	Liver	Caffeine is metabolised; EGCG activates detox enzymes via the Nrf2 pathway (Williamson et al., 2021).
1–6 hrs	Bloodstream	EGCG neutralises free radicals; supports healthy blood sugar levels.
3–6 hrs	Kidneys	Tea polyphenols help flush out toxins with a gentle diuretic effect.
6–24 hrs	Colon	Unabsorbed catechins feed gut flora and gently suppress harmful bacteria. A quiet symphony for our microbiome.

Feel the Flow: Key Moments to Notice

Let our senses guide us. These are the moments when tea subtly shows its magic:

• 5 minutes in: A lift of gentle alertness from caffeine
• 30 minutes: L-theanine tunes our mind — focused, calm, inspired
• 2 hours: EGCG is at its peak — antioxidant protection and metabolic support
• 6 hours: Caffeine has left the stage; our body settles into soft rhythm
