When should you drink green tea?
To enjoy many health benefits, users should drink green tea in the morning or before a workout.
Many people may be surprised to learn that drinking green tea can affect their ability to reap the benefits or put them at risk of some side effects if taken incorrectly.
Tea contains tannins, essential oils, vitamins, proteins, minerals and pigments. In particular, this drink contains caffeine, which stimulates the central nervous system, cardiovascular activity, kidney function and digestion.
The mind-boosting properties of this drink are attributed in part to caffeine, a stimulant shown to improve focus and alertness. But unlike coffee and other caffeinated beverages, green tea also contains L-theanine, a calming amino acid.

Research published in the US National Library of Medicine in 2008 shows that L-theanine and caffeine work together to improve brain function and mood without the negative side effects that can occur with caffeine alone. For the above reasons, to have great effectiveness, we must enjoy this tea in the morning before starting a new day.
Drinking green tea before a workout is also beneficial. Research shows that consuming green tea extract before a workout increases fat burning by 17%. Another study in women showed that drinking 3 servings of green tea the day before exercise and an additional 2 hours before exercise increased fat burning.
The tea can also speed up recovery after intense exercise.
There are many health benefits, but using this tea incorrectly can have some downsides.
It prevents the absorption of nutrients: Certain compounds in green tea bind to minerals in the body and prevent their absorption. In particular, the tannin compound found in green tea acts as an antinutrient and reduces iron absorption.
Research shows that the epigallocatechin-3-gallate (EGCG) in green tea can bind to minerals like iron, copper and chromium, preventing their absorption into the body.
Other studies have also shown that drinking tea with meals decreases iron absorption, which can lead to deficiency over time. Therefore, it is best to drink green tea between meals.
What causes sleep disturbances in some people: An 8-ounce cup of green tea contains about 35 mg of caffeine. That’s a lot less than the 96 mg of caffeine in a cup of coffee, but it can still cause side effects for sensitive people.
Common side effects of excessive caffeine consumption include anxiety, high blood pressure, restlessness and nervousness. Caffeine can also cause trouble sleeping. Therefore, if you are sensitive to caffeine, you should drink green tea 6 hours before bed to avoid problems.
