Our labs found that Irwin Naturals contained 26% to 27% more cannabinoids than suggested by their label.
We purchased this CBD product and tested it at independent testing facilities to measure levels of CBD, THC, and other cannabinoids and compare the results to the manufacturer's claims. Here are the results. (Learn more about our review process.)
From Lab A
Other Cannabinoids (mg / mL)
Irwin Naturals claims this is a full-spectrum extract. Our lab tests confirmed that it is a full-spectrum hemp extract that contains CBD, THC, CBC, and trace amounts of other cannabinoids.
* Products tested prior to 2020 were sent to only one independent testing facility.
Irwin Naturals has formulated “best-in-class” supplements that address a wide spectrum of health needs.
Develop best quality supplement products at affordable prices, focused on superior potency, bioavailability, and absorption. Our extensive line of 100+ supplements uses an all-liquid soft-gel delivery that offers superior advantages over hard tablets and capsules that can often be hard-to-digest. Plus, our signature BioPerine Complex enhances nutrient absorption and potency. Our goal is to bring you targeted formulas with quality ingredients at effective levels.
For now, it’s better to stick to more trusted brands, like CBDistillery or Lazarus Naturals.
As for customer service, we emailed the company to see their third-party lab test reports before purchasing a product.
It claims to use American hemp but doesn’t provide an exact source. You also can’t see the third-party test results without buying a product. On top of that, there’s a lack of customer reviews.
Overall Rating: ☆☆☆ 3/5
Here’s a detailed look at Irwin Naturals’ CBD products.
While Klee’s mission is commendable, Irwin Naturals needs to be more transparent before it’s considered a reputable source of CBD.
Irwin Naturals has a wide range of products, including CBD oil tinctures, topical balms, capsules, skincare products, and CBD-infused edibles and drinks.
It’s also hard to confirm that Irwin Naturals uses full-spectrum hemp extract when we can’t look at the test results. The only available document shows a fairly weak formula with small amounts of non-CBD cannabinoids.
