The suitable amount of CBD varies on the basis of various factors. First, of all, you have to figure out whether it is a full or broad-spectrum CBD. For health benefits, you may need a daily dosage ranging from 50-to-600 mg. Issues like anxiety, diabetes, cancer and Parkinson's require different dosages as per the age and health condition of a person. It is advisable to consult with a physician who can diagnose and recommend a precise amount.
