Medterra does lab test all of their products and posts the results online. The company tests for both potency and purity by an independent lab. Medterra also uses CO2 extraction methods, the industry gold standard, to obtain the CBD. CO2 extraction methods use pressure and temperature to process the plant material, which preserves the cannabinoids more effectively over extraction methods that use solvents.
Medterra sources its hemp from the Kentucky Department of Agriculture Industrial Hemp Pilot Program which requires an application to be accepted. Participants must track data to contribute to research and currently, only 250 participants are enrolled in the program. Kentucky hemp is widely sought after because the growing season is longer and the soil is richer than many other states.
