This is a difficult question to answer. Proper dosing will vary by weight, age, gender, metabolism, activity level, what you are trying to treat, and how your body reacts to cannabinoids. Unfortunately, there are too many variables to give rigid dosing guidelines. Fortunately, there have been no known cases of people overdosing on CBD products. Regardless, it is still best to start at smaller doses and work your way up until you hit an effective dosage. Starting with 16.7mg, half a dropper or one gel cap, 1-2 times a day is a good starting point for most people. For larger and more active people, you might find that doses of 66.7mg or more a day are appropriate, 2 full droppers or 4 gel caps. There are even quite a few people that take 100mg or more a day.
