JKPHOTO,

Bioavailability is one of the key aspects of CBD oil.

Bioavailability is the percentage of CBD that is actual absorbed and introduced into the body. Edibles have the lowest bioavailability with ranges from 4% - 20%. Sublingual (under tongue for two minutes) is much higher bioavailability with ranges from 20% - 35%.

So 325 mg via capsules would only introduce between 14 - 65 mg of CBD into your system. If you used drops under the tongue for two minutes your bioavailability of 325 mg of CBD would be between 14 - 114 mg of CDB

Make sure the items you are purchasing have the amount of CBD per serving on label which is usually one dropper which equals 1 ml
