Tea has long been considered a beloved beverage around the world, known for its refreshing taste and potential health benefits. From black tea to green tea, there are various types of tea available, each with its unique flavours and characteristics. Compounds present in tea like caffeine, theanine, and antioxidants, which can provide numerous health benefits. However, like with any food or beverage, moderation is key. Research suggests that consuming too much tea can have adverse effects on health.
Caffeine is one of the primary bioactive compounds found in tea. It is a natural stimulant that can increase alertness and improve concentration. However, excessive caffeine consumption can have negative effects on health.

Consuming too much tea, especially those with high caffeine content, can result in exceeding the recommended daily caffeine intake, which varies depending on age, sex, and overall health.According to the Mayo Clinic, caffeine doses of up to 400 milligrames per day are considered safe for most people.
Effect Of Tea Consumption On Your Overall Health
Excessive tea consumption can also lead to an overdose of other bioactive compounds, such as catechins, which are antioxidants found in tea. While catechins have been linked to numerous health benefits, including reduced risk of heart disease, cancer prevention, and improved weight management, excessively high levels of catechins can have negative effects on health. A study published in the Journal of Clinical Pharmacology found that an overdose of catechins from tea extracts can lead to hepatotoxicity, which can cause liver damage. Another study published in the European Journal of Clinical Nutrition reported that excessive consumption of green tea extract supplements, which are high in catechins, was associated with an increased risk of liver injury.
Tea can reduce the absorption of iron from plant-based sources, such as vegetables and grains, due to its high content of tannins, which are a type of polyphenol. This can be especially concerning for individuals who are already at risk of iron deficiency, such as pregnant women or those with anemia. Additionally, tea can also interfere with the absorption of calcium, which is crucial for bone health, and may lead to calcium deficiency if consumed excessively.
