Please note that this is essentially a rough calculation based on the information that you provide. The number of drops per bottle is a subjective estimate that can vary, depending on the manufacturer. All variables can be used as a guide but, is should not replace any medical advice or guidance. If you are unsure, please seek advice from your medical professional.
As a first step, you will need to read the details on the CBD packaging. Good manufacturers will provide all the details needed to calculate your dose, however, you will need to work out the calculation for how many drops/mg you will need per day to meet your personal need.
