Green tea is one of the most popular beverages worldwide, known for its pleasant taste and numerous health benefits. It contains several bioactive compounds that can improve brain function, promote weight loss, reduce the risk of chronic diseases, and much more. However, many people wonder if there is a best time to drink green tea to optimize these benefits and avoid potential drawbacks. In this article, we will explore the latest research on the best and worst times of the day to drink green tea.
In the morning
Drinking green tea in the morning is a common practice among tea lovers who want to start their day off on the right foot. But does it offer any specific advantages over other times of the day? According to scientific evidence, yes, it does.

One reason why drinking green tea in the morning may be beneficial is its caffeine content. Like coffee and other caffeinated drinks, green tea contains caffeine, a natural stimulant that can enhance attention, alertness, and mood. However, unlike coffee, green tea also contains an amino acid called L-theanine, which has calming effects on the brain. When taken together, caffeine and L-theanine can improve cognitive performance and prevent the negative side effects that caffeine alone may cause, such as jitteriness, anxiety, and insomnia.
Moreover, drinking green tea in the morning may help you stay focused and productive throughout the day. A study published in the journal Nutrients found that consuming green tea extract before performing demanding cognitive tasks improved working memory, reaction time, and task-switching performance compared to placebo (1). These effects were more pronounced in individuals who had low cognitive abilities at baseline, suggesting that green tea may be particularly beneficial for those with impaired mental function.
Overall, drinking green tea in the morning seems like a smart choice for anyone looking to boost their energy, concentration, and brain power. Just be mindful not to overdo it, as excessive caffeine intake may lead to jitters, headache, and other unpleasant symptoms.

Another potential time to drink green tea is before or after exercise. Research has shown that this beverage may enhance fat burning, improve physical performance, and accelerate recovery from exercise-induced muscle damage.
One study published in the American Journal of Clinical Nutrition investigated the effects of green tea extract consumption on energy expenditure and fat oxidation during moderate-intensity exercise (2). Twenty-four healthy men received either a placebo or 300 mg of green tea extract containing 150 mg of epigallocatechin gallate (EGCG), a catechin abundant in green tea known for its antioxidant and metabolism-boosting properties. The results showed that the green tea group had higher rates of fat oxidation during exercise and increased daily energy expenditure compared to the placebo group.
Similarly, a study published in the Journal of the International Society of Sports Nutrition tested the effects of green tea consumption on muscle damage and inflammation following high-intensity resistance training (3). Fifteen young men were randomly assigned to receive either 500 mg of green tea extract or a placebo daily for two weeks. After performing a strenuous leg press exercise, the green tea group had lower levels of inflammation markers and muscle damage indicators than the placebo group, indicating that green tea may have protective effects against exercise-induced stress.
It’s worth noting, however, that the optimal timing and dosage of green tea intake for exercise-related benefits are still unclear and may vary depending on individual factors such as body weight, fitness level, and activity type. Additionally, drinking green tea too close to bedtime may interfere with sleep quality, which is crucial for muscle recovery and overall health.
May impair nutrient absorption at mealtimes
While green tea has many health-promoting compounds, some of them may interfere with nutrient absorption if consumed with meals. One class of compounds called tannins, found in high amounts in green tea, can bind to minerals such as iron, zinc, and calcium in the gut and reduce their uptake by the body.

A review published in the Journal of Food Science and Technology examined the effects of green tea consumption on mineral bioavailability from food sources (4). The authors found that drinking green tea during or immediately after meals reduced the absorption of iron and zinc, two essential nutrients for blood and immune health. Other studies have reported similar results for calcium absorption, which may lead to bone loss and other adverse effects if consumed chronically.
To minimize the risk of nutrient interference, it’s advisable to consume green tea at least 1-2 hours before or after meals and avoid taking supplements containing iron or other minerals together with green tea. If you have a history of anemia or other mineral deficiencies, it’s best to consult a healthcare provider before regularly drinking green tea.
May disturb sleep in some people
As we mentioned earlier, green tea contains caffeine, which can promote wakefulness and alertness but also interfere with sleep quality if consumed in excess or at the wrong time. While individual sensitivity to caffeine varies, some people may experience insomnia, restlessness, or anxiety if they drink green tea too close to bedtime.
A study published in the Journal of Clinical Sleep Medicine investigated the effects of caffeine intake on sleep quality in 50 healthy adults (5). The participants consumed either a placebo or 200 mg of caffeine (equivalent to 1-2 cups of coffee or green tea) 0, 3, or 6 hours before their usual bedtime. The results showed that caffeine consumption at all three time points significantly reduced total sleep time and sleep efficiency compared to placebo, indicating that even small amounts of caffeine can disrupt sleep patterns.
Therefore, if you’re sensitive to caffeine or have trouble falling asleep, it’s best to avoid consuming green tea in the evening or close to bedtime. Instead, you may opt for decaffeinated green tea or herbal teas that promote relaxation, such as chamomile or valerian root.
Conclusion
In conclusion, drinking green tea can offer many health benefits, but the best time to consume it depends on your goals, preferences, and individual circumstances. If you want to enhance your cognitive performance and energy levels, drinking green tea in the morning may be a great choice, thanks to its caffeine and L-theanine content. If you’re looking to improve your exercise performance and recovery, drinking green tea before or after workouts may help burn fat and reduce muscle damage. However, be mindful of the timing and dosage of green tea intake, as well as the potential interference with nutrient absorption and sleep quality. By following these guidelines, you can enjoy the benefits of green tea while avoiding any adverse effects.
