My favorite CBD oil right now is Naternal’s full-spectrum. I like it for a variety of reasons, but mainly for the strength of the oil, the clean flavor, and the noticeable calming effects. A small dose is good for nerves, a larger makes me sleepy. The 2400mg bottle offers 80mg of CBD per serving, which is a good, strong dose for a larger guy like me. For smaller folks, the 600mg bottle (20mg of CBD per serving) is plenty.
