It is hard to find simple information about how much CBD you should take and what happens if you take too much CBD. An effective dose of CBD for most users is between 5-25mg per day. Doctors prescribe much higher doses to patients with specific medical conditions using body weight dosing up to 40mg per kg (around 1500mg) per day.
A potentially harmful dose of CBD is around 20,000mg which is the same amount as in 13x bottles of our Colorado or Oregon oils. In other words, you cannot overdose on CBD, it is well tolerated and has a good safety profile as recognized by the World Health Organization.
CBD is non-toxic, non-addictive and there is no evidence of the recreational use of CBD, CBD overdosing or any other public health-related problems associated with using full spectrum CBD extracts.
If you take too much CBD such as ingesting 75mg instead of 25mg you will not have any adverse health side effects. What you may find is that the CBD is less effective. CBD is a botanical extract which requires some experimentation to find the exact level that is effective for you. Dosing CBD is about starting low and increasing slowly until you find the perfect amount - usually between 15-25mg a day for wellness benefits.
