What are the potential benefits of green tea?
Green tea is believed to be a powerful antioxidant
Green tea is believed to be a powerful antioxidant. Green tea is thought to be a potent antioxidant. Rich in polyphenols (catechins, particularly EGCG), it is believed to help reduce the risk of numerous conditions. Antioxidants help protect our body against free radical damage and premature cellular ageing. Scientific research suggests that green tea may positively impact cardiovascular health and other conditions, notably thanks to the quercetin and kaempferol it contains. So, whichever tea variety you choose (green, black, or white), enjoy the antioxidant properties of this energising daily drink. Perfect to boost your immune system!
Green tea may support brain health
Green tea is believed to have positive effects on cognitive functions. Its aforementioned antioxidant properties could benefit the brain at multiple levels: Green tea can help with focus. The presence of caffeine in green tea is thought to enhance concentration, keep you alert, and give you a boost during the day. Memory and green tea go hand in hand: green tea may also support brain function by promoting cognitive performance. Drinking several cups of green tea could strengthen neural connections, thereby supporting memory. This is why you will find numerous scientific studies exploring green tea and its close link to Alzheimer's disease.
Green tea could be a natural stress reliever
Green tea could be a natural stress reliever. What if all it took was gifting a tea infuser and a fine green tea to soothe everyday stress? Contrary to what one might think, notably due to caffeine, green tea contains compounds that promote relaxation. It is the theanine (or L-theanine) in green tea that is thought to have a beneficial effect on stress and anxiety. Studies on theanine's activity in the brain have shown reduced mental and physical stress alongside a relaxing effect. In short, green tea is great for your mood! Ready to adopt this philosophy? At Kusmi, we gladly embrace the tea-break ritual to enjoy the benefits of green tea.
Green tea: a slimming ally?
We would never promise miracles; however, drinking green tea may support weight loss. Combined with a balanced, varied diet and regular physical activity, green tea—rich in catechins (polyphenols) and caffeine—promotes elimination and influences fat distribution in the body. Very low in calories, it can also help curb cravings and limit snacking. Overall, drinking hot beverages like green, black, or white tea has a draining effect. These draining and diuretic qualities can help reduce water retention and ease the feeling of heavy legs. Green tea is thus a delightful ally for staying in shape.
Green tea, a natural source of energy
Did you know that the caffeine found in tea and coffee is the exact same molecule? Green tea provides a natural source of energy that diffuses gently throughout the body, keeping you revitalised throughout the day. At Kusmi, we love drinking green tea after meals for its digestive benefits. But a cup of green tea is also perfect in the afternoon for a welcome pick-me-up. The green teas richest in caffeine are Matcha, Sencha, Gyokuro and Tencha. Paired with ginger or lemon, a boost of vitality is guaranteed! Discover the best time to drink green tea!
Does green tea have any side effects?
Many still wonder about the link between iron absorption and green tea. When consumed in excess, green tea can indeed hinder iron absorption. However, it is important to note that very large quantities would need to be consumed for this effect to occur. Daily green tea consumption should remain moderate and not exceed 5 cups. So rest assured, the benefits of green tea far outweigh any potential side effects.
When should you drink green tea?
Knowing the benefits of green tea makes it easy to see when a cup is most rewarding. Green tea can be enjoyed at any time of day. Having green tea in the morning offers a gentle, refreshing wake-up call. It is no coincidence that one of our organic green teas is named Lovely Morning! After lunch or during a mid-morning break, green tea helps you unwind whilst boosting your energy and focus for the rest of the day. As for enjoying green tea in the evening, opinions vary. Does green tea keep you awake? Yes, no, and above all, "it depends". Just like caffeine sensitivity, individual responses to tea vary. Some find it impossible to sleep if they drink green tea after 5pm, while others sleep like a baby. While certain studies remain debated, the benefits of green tea are plentiful. Now it is up to you to decide. Which green tea will you choose to enjoy its benefits? Explore our green tea collection at Kusmi.
How to choose the right organic green tea?
Green tea is known as the quintessential Asian tea, being the most widely consumed tea in China, Korea and Japan, whereas black tea is more popular in the West. Another key difference with black tea: green tea undergoes less processing, as it is only partially oxidised.
Between black tea, green tea, white tea, and caffeine-free infusions, it is easy to feel spoilt for choice. If you have already set your sights on green tea, the hardest part is done! But which organic green tea should you choose? Just one more step to start enjoying the benefits of green tea. At Kusmi, our organic green tea range offers plenty of choice. And because we love catering to every taste, you will find as many flavoured green teas as plain green teas. Still undecided? Discover the benefits of plain teas like genmaicha, sencha, matcha, gyokuro and bancha, or flavoured blends such as our ginger green tea.

Organic loose-leaf green tea or organic green tea bags?
While tea bags are wonderfully convenient, loose-leaf is ideal for savouring your plain organic green tea. Indeed, any true tea lover will tell you: loose-leaf tea delivers a much richer, fuller flavour. Loose-leaf green tea has the advantage of unfurling vibrant notes and fully releasing its essential oils. However, green tea in bags remains very practical for enjoying on the go and preserving flavours over time. Either way, at Kusmi, the choice between loose-leaf or tea bags is always yours.
