Some of those products, which don’t include the CBD amount on their label, market themselves as “whole plant” or “full spectrum” hemp products, or say they are rich in other compounds from the plant, such as various fatty acids. Though it’s possible that those other compounds provide additional health benefits, that’s still uncertain. In those cases, you could check the COA, if they have one, which should list how much CBD or THC they contain.
Overall, based on my personal HempWorx CBD oil review I would probably recommend HempWorx for people who have been (or plan on) using CBD as a routine daily treatment. Their 750 CBD oil was pretty effective for may anxiety and panic attacks, and it definitely helped me get to sleep in the evenings where I was having more intense episodes than normal.
