How much Kava Kava can I take in a day?

I'm curious about the recommended dosage of Kava Kava. As I'm new to using herbal supplements for relaxation, I'd like to ensure I'm within safe limits. Could you please advise on the maximum amount of Kava Kava I should consume in a single day? I understand that dosage can vary depending on individual tolerance and other factors, but I'm looking for a general guideline to start with. Thank you for your assistance in this matter.
