It is known that insufficient or toxic levels of boron intake may lead to disruptions in various metabolic pathways. Hence the increase of tea consumption in Türkiye more than other countries day by day, the boron intake from tea has become important too. This study aimed to determine the amount of boron in the most consumed teas in Türkiye and its health impact. Black bulk and bagged tea samples were used. All teas were pulverized to a certain size. Then, the teas were brewed under certain conditions and centrifuged. The boron content in pulverized and brewed tea samples was determined by the carminic acid method. The average boron level in dried tea samples was 10 ppm, while in brewed tea samples it was about 3.3 ppm. The boron levels transferred to the brewed tea sample decreased by approximately 3-4 times to around 30%. In conclusion, considering the daily upper limit level, our research supports the safety of tea consumption in terms of boron levels. It also helps fulfill our boron intake without surpassing the daily upper limit, thereby maintaining homeostasis and potentially helping with many health problems.
