Swanson claims to have 25 mg of CBD per 1 mL serving. We found that each 1 mL serving contains about 32 mg of CBD and around 1.2 mg of THC.

*It’s common to see CBD doses at 5 mg, 15 mg, 25 mg, and 50 mg for consumer products. Researchers use much larger doses (25 mg to 1500 mg of CBD). CBD dosing is highly individualized.

Jeremy’s Take

Swanson is one of the first mainstream brands to offer CBD. They came in hot, with 26% to 32% more CBD than claimed by their label. This disparity is concerning if you are looking for an accurate dose. Most people don’t mind the extra CBD as long as the brand is consistent. It’s fascinating that even one of the largest supplement manufacturers doesn’t provide an accurate CBD dose.

Cost: Lab A found that the price per mg of CBD was only 2.6 cents. It’s still only about 3 cents per mg of CBD if they only provide the amount of CBD claimed on their label (our lab found more CBD; thus, a lower price per mg of CBD). Fifteen cents per mg is average. This is a fantastic deal any way you slice it.

Taste: It’s fine. It’s ok. It’s a little weird. This hemp extract is flavored with peppermint and sweetened with monk fruit. The peppermint flavor is robust and natural, perhaps from essential oil. It’s not sweet. It tastes earthy, but I do not taste the natural flavor of hemp. It might taste better than natural hemp extract but it also has a harsh herbal flavor or medicinal flavor.

Strength: Over 30 mg of CBD is a potent dose and the novice should not take a full dropper on the first go. Most people won’t have any trouble with this amount of THC but you should still try it out before operating a vehicle or working. 1.2 mg of THC per day will risk a failed drug test. It’s got decent amounts of CBC and CBG. It’s the full package.

Overall: Swanson’s 25 mg CBD is an excellent full-spectrum extract with many cannabinoids. This CBD is for people who want relief from multiple cannabinoids and don’t mind getting a little more CBD than expected. Ok, a lot more CBD than expected.
