Most Tested. Most Trusted.

Each batch of doTERRA essential oils goes through a battery of rigorous tests to ensure you and your family receive only the most pure, potent, and effective oils on earth. Enter your unique Quality ID to view GC/MS test results from an independent, verified third party lab. We are committed to providing you the highest quality oil, every time.

Proprietary blends are not supported by GC/MS reports, as all single oils in doTERRA blends are tested individually for purity and efficacy prior to blending.
