You need to find a trusted CBD manufacturing company. A company that focuses on quality and transparency is key to finding a CBD wellness product that will be effective. Two main quality items to keep an eye open for are COAs and a medical director.
A COA or certificate of analysis is a test that can show CBD potency and sometimes purity. A quality manufacturer will have two rounds of COA testing. The first round should be a third-party test of the raw CBD oil. This first test should analyze the purity of the oil, from pesticides to residual solvents. The second test is another third-party test on the finished product that should be easily accessible to the user. This second test looks at the potency of the wellness product making sure it is in compliance with the USDA Farm Bill.
Having a medical director on staff is essential when manufacturing CBD products for human use. Cannabidiol has a large effect on human bodily systems. Once CBD enters the body it passes through the bloodstream and interacts with the endocannabinoid system. The medical director will have direct knowledge of the human body and the endocannabinoid system, and help to an extent in formulating the correct CBD dosage and product formulation.
A final note. There are other quality markers to look at that all CBD manufacturing companies should follow such as: no added fillers, organically grown hemp, non-GMO, licensed hemp manufacturer in their state (you should be able to ask for and see their hemp permit), and product liability insurance. Unfortunately, there is a big gap in the market for quality CBD wellness products. Pacific Roots CBD products have the highest quality control on the market to ensure product safety, called the CBDTQM guidelines.
