This practice results in a significantly bolder flavor and a higher dose of caffeine, which can have both desired and unexpected effects on the drinker.

Tea is the world's most consumed beverage after water, but studies have revealed that the tea plant is a hyperaccumulator of fluoride, leading to its presence in your daily cup.

However, this amount can vary significantly based on individual sensitivity, tea type, and preparation methods.

In 2019, a study by McGill University found that steeping a single plastic tea bag at brewing temperature released billions of microplastic particles into the water. This raises a critical question for tea drinkers: is it okay to drink tea leaves from a tea bag if it breaks or if the leaves escape into your cup?

The tea plant, *Camellia sinensis*, is a known hyperaccumulator of fluoride, which means your English breakfast tea can contain significant levels of this mineral depending on several factors. This natural absorption process is central to understanding the fluoride content in your favorite brew.
