Where the evidence is negative

Common claims the trials do not support

'Isolate vs broad-spectrum' superiority claims are marketing — head-to-head human data absent.
Consumer isolates typically dosed far below the 10-20 mg/kg used in trials.
Pain and insomnia evidence weak.

Purified CBD (>99%). Same active molecule as prescription Epidiolex; isolate products still face the mislabelling and dosing-consistency issues of the consumer market.

Safety notes: Same interactions as CBD generally.

Evidence grades reflect study quality and consistency, not marketing claims.
