About the product

Charlotte’s Web claims this is a full spectrum hemp extract. Our lab tests confirmed that it is a full-spectrum hemp extract that contains CBD, THC, CBDa, CBC, CBG, and CBDV.

We found that Charlotte’s Web contained 19.3% fewer cannabinoids than suggested by their label.

You can take this product sublingually or mix with a food or drink.

Update: The product we purchased had “28 mg per serving” on the label for a total of 840 mg in the 30 mL bottle. Their new label for this product now states, “28 mg of hemp extract per serving including 17 mg of phytocannabinoids,” which totals 510 mg of cannabinoids for the entire bottle. However, their purchase page continues to state “Approx. 25 mg hemp extract per 1 mL serving.” Their labeling is confusing and doesn’t provide transparent CBD and cannabinoid levels.

Update: Charlotte’s Web now lists: “17 mg of cannabinoids per 1 mL serving” on their website for this product.

About the company

Charlotte’s Web was founded in 2012 by seven brothers in Denver, Colorado. Charlotte’s Web leads the market of hemp-based CBD products and the company is now public on the Canadian Securities Exchange.

The good:

  • Charlotte’s Web is famous for treating the epilepsy of a girl named Charlotte Figi, which you can learn about in this documentary.
  • Charlotte’s Web has a case study for its success in treating epilepsy, which started a massive movement for CBD.
  • Charlotte’s Web has the most substantial following on the internet out of all CBD companies on the market, with thousands of positive testimonials.
  • The U.S. Hemp Authority awarded Charlotte’s Web a high-quality seal.
  • A- rating by the Better Business Bureau.

The bad:

  • A 2018 report by found that a 28 mg hemp extract by Charlotte’s Web contained only 16.1 mg of CBD per dose and no other cannabinoids.
  • Charlotte’s Web was given an FDA warning letter in 2017 for making false claims about CBD. However, many of the examples were from customers commenting on how much the product helped a variety of medical conditions.
  • We found that Charlotte’s Web contained 19.3% fewer cannabinoids than their label suggested. It appears they have corrected the labeling issue after I published my original review and published their report on the misleading label of Charlotte’s Web. However, Charlotte’s Web’s product labeling could still be more transparent in regards to total CBD and cannabinoid levels. It is difficult for consumers to know what they are purchasing and the quantity that they are purchasing.

Other sizes available

We tested the $74.99 bottle (30 mL) of the Charlotte’s Web Extra Stength. The price drops from about 12 cents to about 9 cents per mg of CBD if you purchase the $188.99 bottle (100 mL).
