Product Overview
Kava Extract Kavalactone Powder is a standardized botanical extract commonly used in botanical ingredient sourcing and supplement formulation projects.
It is usually supplied as a fine powder standardized by kavalactone content, and buyers often review assay level, extract consistency, and documentation scope before technical or commercial evaluation.
It is commonly considered for capsule blends, tablet formulas, and botanical powder systems, with sample support and bulk packaging options available for sourcing reference.

Applications
Dietary Supplements
Suitable for capsule, tablet, and powdered supplement projects where buyers need a standardized botanical extract with defined kavalactone content and supporting technical documentation.
Botanical Powder Blends
Can be considered for powdered botanical combinations where assay consistency, blend compatibility, and packaging practicality are important during sourcing and pilot evaluation.
Private Label Formulas
Applicable to private label or contract manufacturing projects that require a standardized kava extract input with flexible packaging, sample support, and commercial supply coordination.
Wellness Product Development
Used in botanical wellness product development where procurement teams evaluate specification fit, dosage form suitability, and documentation readiness before launch planning.
How to Choose the Right Grade / Form
For general formulation projects
Recommended grade: 30% Kavalactones
A practical option for buyers seeking standardized kava extract for routine formulation work, pilot testing, or broader cost-performance consideration.
For more concentrated supplement formats
Recommended grade: 50% Kavalactones
Often chosen when stronger standardization is needed while still maintaining flexibility for common solid dosage forms.
For higher-strength positioning
Recommended grade: 70% Kavalactones
Better suited to projects where higher assay concentration, lower inclusion volume, or stronger specification positioning is part of the product concept.
Technical & Formulation Notes
Technical Notes
Technical review usually focuses on kavalactone assay basis, extract consistency, microbiological suitability, and alignment between the offered specification and the intended application.
Buyers may also review particle size, moisture, handling behavior, and documentation scope during formulation and sourcing assessment.
Manufacturing & Process
This product is supplied as a standardized extract from Piper methysticum root.
Commercial evaluation typically considers raw material selection, extraction control, concentration process, and standardization consistency across batches.
Compatibility / Formulation Notes
For capsules and tablets, buyers should review assay level, powder flowability, and excipient compatibility during pilot formulation.
For powder blends and sachets, blending uniformity, sensory impact, and target loading should be confirmed before scale-up.
Higher-standardized grades may help reduce inclusion amount, but compatibility with the full formula should still be tested.
The material should be protected from moisture, heat, and direct light to help maintain stability during storage and transport.
Pilot testing is recommended before final specification lock and commercial launch.
Extended QC & Test Items
Depending on project requirements, additional review may include heavy metals, microbiological limits, residual solvent scope where applicable, marker assay method, and other agreed specification items for destination-market evaluation.
