Overview
As an ISO/IEC 17025:2017 accredited laboratory specializing in Kavalactone analysis, you can have full confidence in the potency results we provide. Our commitment to accuracy is further demonstrated by our "Acceptable" performance in the NIST third-party proficiency evaluation (PE), available here.
Our analysis employs high-performance liquid chromatography (HPLC), a sophisticated technique that separates analytes based on size, surface charge, and other properties. The incorporation of ultra-violet (UV) detection with HPLC allows the concentration of analytes to be determined following separation.
Total Alkaloids Analytes (Kavalactones Potency) include:
- Dihydrokawain
- Dihydromethysticin
- Desmethoxyyangonin
- Kawain
- Methysticin
- Yangonin
We also offer optional add-on analyses, including Flavokawain (a.k.a. Flavokavain) potency, Noble Kava, and Tudei Kava confirmation.
Additional testing services include:
- Pathogen analysis via PCR, the most sensitive and specific
- Metals analysis
- Mycotoxins
- Pesticides
- Aspergillus
