Potency (CBD)
Also known as: CBD strength, Cannabinoid potency
Potency is the measured amount of cannabinoids, usually CBD in milligrams, in a product, and the only way to verify it is a lab report (COA) that tests the actual batch.
A bottle label gives a claim: "1,500mg" means the maker says there is about 1,500 mg of CBD in the whole bottle. Potency is what a lab measures in that batch. Labs report it as a percentage by weight or as mg per mL or per gram, and the COA is where you read it. For our 30 mL oils, the label total divided by 30 gives mg per mL. Our 1,500mg bottle is about 50 mg per full dropper and the 500mg bottle about 17 mg.
Label claim and tested value rarely match to the milligram. Industry experts recommend cannabinoid levels within 10% of the advertised amount, per a Leafreport study summarized by SC Labs (checked October 2026). That is a recommendation, not a law we can point you to. Products that test well outside that band exist, and we would rather you check the COA than trust any front label, ours included. Also read the THC line, because a strong CBD number says nothing about total THC.
"High-potency" and "extra strength" are marketing words with no legal definition. A bigger number is also a different serving, not a better product, and price per mg is the fairer comparison. Most adults start at 10 to 25 mg and adjust slowly, and it is worth asking your doctor first. If you do want a higher-strength bottle, our strongest options are listed below.
