Does green tea strengthen our immune system?
Yes, alongside a healthy and active lifestyle, green tea is beneficial for our immune system and helps boost our cells. Specifically, why is green tea beneficial for our health? Green tea has interesting benefits for our immune system:
- Its polyphenol content (including EGCG) gives it several beneficial properties. Indeed, these active compounds are recognised for their antioxidant properties, as well as for their role in our immune system. They help support immunity against foreign pathogens and combat the action of free radicals.
- Furthermore, it protects the body's tissues and cells against oxidative damage.
- It also supports our metabolism.
The antioxidant properties of green tea
Very rich in polyphenols, green tea is a powerful antioxidant. Antioxidants play a vital role in our well-being: they help prevent many illnesses by protecting our bodies against the action of free radicals and premature cell ageing. Antioxidants are therefore beneficial for our health and long-term well-being.
In short, alongside a balanced, varied diet rich in good nutrients and regular exercise, green tea helps boost your immune defences naturally. That is why a tea break is always a good idea. Even more so when it is an organic green tea by Kusmi. Isn't it?
Why look after your immune system?
The immune system consists of cells and organs that work together to protect the body and respond to infections and illnesses. Looking after your immune system every day is essential for your well-being: to avoid winter colds, everyday fatigue, and to maintain energy and vitality. How can you boost your immune system naturally? It is much simpler than you might think: exercise, fresh and varied foods on your plate… and why not a bag of vitamin-enriched tea?
A closer look at matcha tea
Sencha, Gunpowder, Genmaicha green tea… wherever your green tea comes from, they are all likely to have more or less the same properties and benefits. Is matcha powder significantly different? Matcha's richness in catechins, particularly EGCG (epigallocatechin gallate), may make this green tea slightly more interesting for your immune system. Indeed, this powerful antioxidant is present in matcha in much greater quantities than in other green teas. Good news for fans of matcha lattes or iced matcha.

Everything you need to know about vitamin C
We created a green tea naturally enriched with vitamin C because we know how essential vitamin C is to our well-being and health. Humans produce only a small amount of vitamin C, so they can rely on food to meet their daily needs. The French National Agency for Food, Environmental and Occupational Health & Safety recommends an intake of 110 mg of vitamin C per day for an adult. Insufficient vitamin C intake can also lead to everyday fatigue. In addition to preventing energy slumps, vitamin C consumption is essential for the proper functioning of our immune system and our body. Boosted immune defences help us avoid winter colds. Furthermore, vitamin C may also facilitate the body's absorption of iron. However, caution is needed with this commonly accepted information, as empirical evidence is contradictory.

Other foods rich in vitamin C
Did you know that oranges do not have a monopoly on vitamin C? That's right, vitamin C is found in many foods, including fruit and vegetables. Among the 20 best sources of vitamin C are guava, pepper, papaya, kiwi, broccoli and strawberries… Our favourite? Acerola, one of the fruits richest in vitamin C. Acerola is a shrub native to the tropical regions of the Caribbean, whose small red berries are both tangy and rich in vitamin C. In fact, very rich: it contains nearly 30 to 40 times more vitamin C than an orange. Nature does things so well that we can only take inspiration from it! Our Rituel Défenses Immunitaires vitamin course is enriched with acerola to help you contribute to your recommended daily vitamin C intake.
Prefer an infusion? Try herbal teas with fennel, orange, ginseng, blackcurrant or cinnamon…
