What is the best form of kava kava?

As a practitioner in the field of finance and cryptocurrency, I'm often asked about the latest trends and investments. However, today I'm faced with a rather unexpected question: "What is the best form of kava kava?" This question, though unrelated to my usual expertise, intrigues me. Kava kava, a plant used in traditional medicine and as a beverage in Pacific islands, has gained popularity for its relaxing properties. But what's the best way to consume it? Should it be brewed as a tea? Or perhaps taken in pill form? Could there be an extract that offers more concentrated benefits? These are the questions I'd pose to a kava expert in seeking the optimal form of this ancient plant.
