Are you wondering why green tea is an integral part of the daily life of so many natural wellness enthusiasts? This article reveals the scientifically proven benefits of green tea, from cardiovascular protection to metabolic support, improved concentration, and lighter digestion, thanks to the powerful antioxidants of this ancient beverage.
Green teas and proven benefits
Green teas stand out as exceptional health allies thanks to their uniquely high concentration of polyphenols, especially precious catechins that protect multiple organs. International studies confirm their protective effects on the heart, brain, skin and various tissues, providing solid scientific validation for the many benefits of green tea.
Storage is super simple: keep your sachet tightly closed (luckily, it's resealable!), at room temperature, in a dry place away from direct light and humidity. Avoid placing it near heat sources like the oven or stovetops. Spices are sensitive to moisture, so never dip a wet spoon into the sachet. If you follow these basic rules, your powder will retain all its freshness and aromas for several months after opening. You'll notice the spices are still as fragrant and potent with each preparation. A well-preserved sachet ensures a delicious Gingerbread Latte from start to finish! 🌙
Drinking Japanese green tea regularly—about three to five cups a day—significantly reduces mortality risk from heart disease. The large Japanese Kuriyama study (2006), conducted on more than 40,000 adults followed over eleven years, confirmed these long-term cardioprotective effects.
- Reduction of bad cholesterol: Research by Hodgson (2010) and Xu (2020) shows that catechins allow for a moderate but real decrease in LDL cholesterol, thereby improving the lipid profile.
- Decrease in blood pressure: Peng's meta-analysis (2014) reveals that daily consumption leads to a significant reduction in blood pressure.
- Anti-inflammatory action: According to Musial (2020), EGCG catechins act on the inflammatory mechanisms associated with atherosclerosis.
The cardiovascular benefits come from the combined action of polyphenols, which improve vessel function, limit fat oxidation, and reduce inflammation. To take full advantage of them, two to four cups a day are enough, provided the tea is brewed correctly to preserve the active compounds.
Brain and alertness
The natural combination of caffeine and L-theanine in green teas produces remarkable cognitive effects. Haskell’s 2008 study shows that this duo sustainably improves concentration and mental accuracy without causing the jitteriness typical of coffee.
Catechins, and especially EGCG, protect the brain by neutralizing oxidative stress and reducing neuronal inflammation, as explained by Yang (2011). Observations in Japan show slower cognitive decline in regular tea drinkers, while matcha, particularly rich in L-theanine, provides calm, sustained focus for hours.

The antimicrobial properties of catechins present in green teas actively contribute to better oral health by limiting harmful bacteria. Clinical data show a notable reduction in dental plaque and bad breath, making this drink an ideal complement to daily hygiene.

When and how to drink it
To optimize the benefits, here is how to consume green tea effectively:
| Time of day | Main benefit | Recommended dosage |
| On waking (on an empty stomach) | Morning Metabolic Activation | 1 cup (150–200 ml) |
| 30–60 min before exercise | Optimized fat oxidation | 1 cup or 1 g matcha |
| Mid-afternoon | Maintaining alertness and thermogenesis | 1–2 cups |
| After a hearty meal | Digestive support (with mint/ginger) | 1 cup |
Be mindful of tannins, which can reduce iron absorption: leave a 1‑ to 2‑hour gap between drinking tea and your main meals.
Choosing the right variety
Some tips for selecting your green tea:
- Choose teas that are especially rich in catechins, such as matcha or sencha.
- Choose organic green tea to avoid pesticides
- Prefer loose leaves over bags for better quality
- In the evening, opt for low‑caffeine varieties such as houjicha
By following these recommendations, drinking green tea becomes a true daily ally for health and weight loss!
Green teas: safety and limits
Traditional, indispensable, transformative.
Advantages and disadvantages
Drinking green tea the traditional way (as an infusion) is perfectly safe at 2 to 4 cups per day. Studies confirm the excellent tolerance of this age-old beverage. However, some natural components require particular attention depending on your profile.
Caffeine is the main element to watch:
- A healthy adult should not exceed 400 mg per day
- For a pregnant woman, the limit is 200 mg
A cup of green tea contains between 20 and 70 mg of caffeine depending on the variety. Too much can cause sleep disturbances, anxiety, or heart palpitations in sensitive individuals.
- Impact on iron absorption: Tannins can reduce non‑heme iron absorption by 60%. To limit this effect, wait 1 to 2 hours after meals before drinking your tea.
- Drug interactions: Green tea promotes certain interactions with medications (anticoagulants, statins, antihypertensives). Consult your doctor if you are on regular medication.
- Why 100 bristles? Because it's the perfect number to incorporate air, create foam, release aromas. No more, no less. Centuries of trials to achieve this geometric perfection.
- Digestive issues: Tannins can irritate the stomach. To avoid this, choose gentle teas like bancha or avoid drinking on an empty stomach.
Regarding sleep, be aware that L-theanine has a relaxing effect but does not fully offset caffeine. Most people should avoid green tea after 4 PM to help maintain good sleep, but this sensitivity varies greatly from person to person.
Who Should Be Careful
Green teas and their proven benefits: antioxidants, weight loss, digestion. Discover how to drink green tea to enjoy its health virtues.
People with anemia: Leave at least one hour between your green tea and meals so as not to reduce iron absorption. Pairing it with vitamin C–rich foods can help offset this effect.
Sensitive individuals (anxious, heart conditions, insomnia): Choose low-caffeine versions such as houjicha. Green tea normally provides calm alertness thanks to its polyphenols, but everyone reacts differently.
Medication: If you’re taking anticoagulants, statins, or stimulants, talk to your doctor before making green tea a regular habit.
Best practices for use
Choose an organic, high-quality green tea to limit exposure to undesirable substances. This organic blend cleverly combines the antioxidant properties of green tea with other plants for a balanced energizing effect.
Store your tea in an airtight container, away from light and heat, to preserve its catechins (for up to 18 months). Matcha, which is more delicate, should be kept in the fridge and consumed quickly. Japanese matcha is a super-concentrated source of antioxidants, particularly EGCG, which offers exceptional benefits.
Frequently Asked Questions
Is it good to drink green tea every day?
Drinking green teas daily (2 to 4 cups) offers numerous health benefits: improved cardiovascular function, boosted metabolism and stronger cognitive performance. Studies conducted in Japan show that this habit significantly reduces overall mortality. To fully benefit from the effects of catechins, keep your caffeine intake below 400 mg/day, wait an hour after iron‑rich meals, and brew your tea at 70–80°C.
What are the main benefits of tea for the heart and brain?
Green tea contains powerful antioxidants like EGCG and polyphenols, which help lower LDL cholesterol and reduce blood vessel inflammation.
