Certificate of Analysis (COA) Results Interpretation
While companies claim lab testing, no one does it like ETHA. Properly reading a Certificate of Analysis (COA) for kratom is crucial for safety, quality, and efficacy. No matter where you choose to purchase your kratom, use the information below to understand and interpret kratom COAs.
Kratom Potency: Alkaloids
Current kratom regulations only require potency testing for Mitragynine and 7-Hydroxymitragynine. However, mitragynine has several isomers, additional important alkaloids that are similar in chemical structure to mitragynine. These isomers have different pharmacokinetics effects related to kratom’s varied benefits. Additionally if labs do not specifically test for these isomers, mitragynine potency may be overstated.
FOR ACCURATE POTENCY, LOOK FOR:
• Mitragynine
• 7-Hydroxymitragynine
• Speciociliatine
• Speciogynine
• Paynantheine
• Isorhynchophylline
• Mitraphylline

Collaborations
360-degree, Complete Testing
At ETHA Labs, we use well-established laboratory procedures to test our botanicals in-house. We also partner with universities like Oregon State University and 3rd-party, independent laboratories to provide confidence and transparency in our botanical analysis.
While companies claim lab testing, no one does it like ETHA.
GROWING KNOWLEDGE
We understand the importance of horticulture as it sheds light on a plant's medicinal potential. That's why we grow Kratom in our ETHA Labs Greenhouse.
Plant morphology can vary tremendously: soil conditions, amount of sunlight, frequency of available water, natural fertilization, pollution levels, and even what is living within the soil.
Additional factors, such as how kratom is harvested and pruned impact how the plant develops, matures, and what bio-active alkaloids are produced.
