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.)
The unadulterated test results on this page come directly from these certificates of analysis from two independent labs, which we pay directly. These are two independent lab tests of one product, at one point in time. We do not guarantee that all products or labs will produce the same results. Lab results may differ based on the different methodologies of testing used by each lab or inconsistencies in the product. Added ingredients may affect lab results. Volume of creams and edibles may change due to factors such as temperature, and this may impact lab results. Learn more about our review process.
Medterra claims to have 100 mg of CBD per 1 mL serving. Lab A found 101.73 mg of CBD. This is an absurd amount of CBD. A lot of people start with a dose of around 5 or 10 mg of CBD. However, some patients under a physician's care take several times this amount.
*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.
The average pure CBD product goes for 7.5 cents per milligram of CBD. 4.4 cents per milligram of CBD is a good deal for a premium brand such as Medterra.
Instructions: Use dropper to apply desired amount of CBD oil under tongue, hold, then swallow.
Disclaimer: The trace levels of THC reported by lab B were reported as below the LOQ and are inaccurate. See below.
Medterra claims this is just CBD. Lab A found that to be true with insignificant amounts of other cannabinoids. Lab B found trace levels of THC below their level of quantitation (LOQ) or under 0.035%. They detected THC but could not accurately measure it. I’m calling this THC free because they could not accurately measure the THC and our second lab found zero THC. Our lab tests of other Medterra products support their THC free claims.
The independent labs found that Medterra contained 1.73% to 14.28% more CBD than their label suggested.
Medterra is my go-to brand for THC-free CBD products. That's why I was surprised to see lab B show trace levels of THC. However, lab B reported those trace levels as below their LOQ or below their level of accurate reporting. I'm listing this as THC free because lab B can't accurately measure those trace levels of THC, which were not confirmed by lab A. My lab tests on other Medterra products also ensure that they offer squeaky clean CBD products.
This tincture is excellent. It's just CBD and MCT oil. The viscosity is light and tastes a tad sweet with zero hemp flavor. The packaging and bottle are premium. The dropper is labeled with milliliter markers so that you can take less. And you might need to. 100 mg of CBD is a large dose. If you're a novice to CBD, move along, this isn't for you.
