Green tea extract has gained popularity as a health supplement due to its numerous potential benefits. One of the key components that contribute to its health-promoting properties is potassium. In this comprehensive article, we will explore the potassium content in green tea extract, its importance for our health, and the various factors that influence its concentration.
Green tea extract is derived from the leaves of Camellia sinensis, the same plant used to make green tea beverages. It contains a concentrated form of the active compounds found in green tea, including polyphenols, catechins, and various minerals[1]. Among these minerals, potassium plays a crucial role in maintaining overall health and well-being.
Potassium Content in Green Tea Extract
The amount of potassium in green tea extract can vary depending on several factors, including the processing method, the part of the plant used, and the extraction technique. However, research has shown that green tea is generally a good source of potassium.
According to studies, dried green tea leaves contain approximately 2,000-2,500 mg of potassium per 100 grams[9]. This translates to about 20-25 mg of potassium per gram of dried green tea. However, it's important to note that green tea extract is a concentrated form of these leaves, and the potassium content may differ.
