Reduce iron Absorption

Iron, a mineral needed by the body for growth and development according to the National Institutes of Health, may be affected by drinking so much tea. 

Eat This Not That notes that the tannins present in the tea (which makes the taste of it bitter) may impair the body's ability to absorb iron when consumes too much. They add that this was demonstrated by a study published in Food Research International. The reminds to eat iron-rich foods so avoid iron deficiency. 


Surprisingly even though teas are in the form of liquid, Nutritionist from Fortis Hospital, Dr. Simran Saini notes in an interview with NDTV Food that excess consumption of tea means an excess consumption of caffeine which can reduce the absorption abilities of the tubules resulting in dehydration. 

Healthline adds that caffeine can cause the diuretic effect that can cause an individual to urinate more frequently and replenishing the fluids after that is needed to avoid hydration.

Liver Damage

Eat This Not That mentions a study by Food Research International that demonstrates higher levels of fluoride in higher-priced, higher-quality tea bags being sold in the market. The site notes that if an individual consumes more than 4 cups of tea a day, the ideal daily intake of fluoride can also be compromised, and can damage teeth, bones, and joints. 

However, the National Kidney Foundation notes that there are no specific recommendations about fluoride intake and kidney disease because of limited available research. 

Poor Sleep

Healthline mentions that since teas have caffeine, excessive intake of the beverage can disrupt the sleep cycle of an individual. They add that lack of sleep is linked to a variety of mental issues like fatigue, impaired memory, and reduced attention span. 

Heavy Metal Contents

Eat This Not That adds that white, green, and black tea with citric acid may contain higher levels of cadmium, aluminum, and lead, as mentioned by a study

High levels of these metals, can be dangerous as it may cause heavy metal poisoning as per Rare Diseases

Although teas promise health benefits, remember that everything that is not in moderation can cause dangerous side effects or manifestations. Take it easy, use the tea for relaxation instead of binge drinking it.
