Scientific studies published using various CBD strengths

Scientific studies published using various CBD strengths


The variance in CBD strengths are the distinguishing factor between the different therapeutic indications.

CBD produces a biphasic response with different doses of CBDi. Dosing is closely related to weight and is reported mg/kg/day. Using the global average body mass of 62 kg (adult) the same conversion rate is used to convert mg/day. For example, 1mg/kg/day is equivalent to 62mg/ day for an average adult. Various scientific literature shows therapeutic CBD doses ranging from 1mg/kg/day to 50/mg/kg dayii. A summary of therapeutic benefits linked to defined CBD doses are presented in Table 1.
