The optimal dosage of CBD oil may vary from person to person due to factors such as body weight, metabolism, individual tolerance and the reason for taking CBD. To determine if your CBD oil dosage is right for you, it is recommended to start with a low dose and carefully observe the effects. If you do not experience the desired results after a reasonable period of time, you can gradually increase the dose. Keep in mind that patience is key, as the effects of CBD may take time to fully manifest. It's also a good idea to keep a journal to track your experience, noting the amount of CBD used, the effects experienced, and the circumstances surrounding each intake.
