As we are all built differently, there is no exact amount prescribed that you must keep to when using CBD oil. It all boils down to what makes you, personally, feel best, and the best way to figure that out is through trial and error.
The easiest way is to start with a low dosage, and then work your way up. Take one drop the first day in the morning and evening, and then increase with one drop until you feel like you’ve found the perfect amount. That can be anything from 2 drops/day to 35 drops/day. There have been cases where people have been able to decrease their intake of CBD as well, as their bodies have gotten used to it and no longer required as much, so pay attention to how your body is behaving. Also be aware to not go overboard with the drops, because that is both a waste of product and can in some cases even lead to reversed effects. If you start to feel more tired than usual, that might be an indication that you should lower your dose.
