What does COA certification mean?

COA stands for Certificate of Analysis, a report from an independent laboratory. It tells you exactly what is in the product you are buying and what is not. Here we cover what the certificate confirms and how to read it.

What does a COA confirm?

A good COA confirms two things: potency, meaning how much CBD is actually in the product compared to what the label states, and purity, meaning the product is free from unwanted substances such as pesticides, heavy metals, and mold.

How do you read a COA?

Certificates can look different, but these are the details worth finding:

• Cannabinoids: the amount of CBD and other cannabinoids, such as CBG, compared to what the label states.
• THC: whether the product contains THC and how much. Read more about the difference between full-spectrum and broad-spectrum oil.
• Unwanted substances: test results for pesticides, heavy metals, and mold.
• Laboratory and date: who carried out the testing and when.

Why does this matter?

When comparing CBD products, the COA is one of the first things worth checking. If a seller cannot show you a certificate, that itself is an answer. Compare strengths and products in the CBD oil collection, or read the basics in the article what is CBD.
