Testing & Transparency
Every batch of Mett Naturals CBD is third-party lab tested, and we publish the results. This page covers how we test and how to read a Certificate of Analysis (COA), so you can check any product for yourself.
Is every batch of Mett Naturals CBD tested?
Yes. Every batch of Mett Naturals CBD is tested by an independent third-party lab, and we post the Certificate of Analysis (COA) on our site so you can read the results yourself. Testing starts before that, too. We test the soil before planting, because hemp takes up what's in the ground it grows in.
Who tests Mett Naturals products?
An independent third-party lab, meaning a lab that Mett Naturals doesn't own or run. A COA usually shows the lab's name, the date the sample was tested and the methods the lab used. Open any report in our COA library to see those details for that product.
Where do I find the COA for my product?
Go to our COA library. Reports are grouped by product type: tinctures, softgels, gummies and topicals, which covers the roll-on, balm, creams, face serums and bath soaks. Find your product, open the PDF, and you'll see the full lab report. If yours isn't listed, email help@mett.com and we'll point you to it.
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a lab report for a specific batch of a product. It lists what the lab tested for and what it found. For CBD, the report usually starts with cannabinoid potency. Many COAs also include contaminant panels, such as heavy metals, pesticides and residual solvents.
How do I read the potency results?
The potency section lists each cannabinoid the lab measured, such as CBD, CBG, CBN and THC, with an amount next to each one. Labs may report this as a percentage, in mg per gram or in mg per mL. Compare the CBD result with the mg listed on your label, keeping the bottle size in mind.
What does the THC result tell me?
It shows how much THC the lab found, usually as delta-9 THC and sometimes as total THC. The 2018 Farm Bill defines hemp as cannabis with no more than 0.3% delta-9 THC on a dry weight basis. Full spectrum products contain trace amounts of THC. Broad spectrum products have had the THC removed.
What do the heavy metals and pesticide results mean?
These are contaminant tests. A heavy metals panel checks for metals like lead, arsenic, cadmium and mercury. A pesticide panel screens for residues of farm chemicals. Each line usually shows the amount found, the limit the lab tested against, and a pass or fail result. Check your product's COA to see which panels it includes.
What are residual solvents?
Residual solvents are traces of solvents that can be left in a hemp extract after processing. A residual solvents panel lists each solvent the lab looked for and the amount it found, if any. Not every COA includes this panel, so open the report for your product to see which tests were run.
What does ND mean on a COA?
ND stands for "not detected." It means the lab did not find that compound above its limit of detection, the smallest amount its method can pick up. You may also see "<LOQ," which means the amount was too small for the lab to measure precisely, even if a trace was there.
