product introduction
Kava extract is extracted from the roots of the Piper methysticum plant. The core ingredient is kavalatone. It is widely used in dietary supplements and herbal preparations in Europe and the Americas. We use HPLC methods to monitor the kavalactone content. As a manufacturer specializing in extracts for over 15 years, we can provide external inspection reports, COAs, etc. Our best-selling product is 0.5% water-soluble calvalactone, as this specification is the most widely used in the market and offers excellent value for money.
Our kava material mostly comes from Fiji and Vanuatu:
Vanuatu: Due to Vanuatu's strict export regulations, it only produces Noble kava, which is superior to kava from other regions in terms of potency, flavor balance, and safety.
Fiji: Fiji is also a major kava producer, with large output and a wide variety of varieties. Fijian kava is typically milder in taste, with an earthy aroma, suitable for everyday drinking. The famous "Waka" variety originates from Fiji.
Samoa and Tonga: While also cultivated in these regions, their international recognition in the high-end market and their strict grading system are slightly less stringent than those of Vanuatu.
Process Flow
Supercritical Process:
Raw material selection → Washing → Crushing → Supercritical extraction (temperature, pressure) → Drying → Crushing → Sieving → Packaging → Testing → Warehousing (after passing quality control)
Ethanol Extraction Process:
Raw material selection → Three-stage reflux extraction with 75% ethanol → Concentration → Filtration → Crystallization and drying → Crushing
Product benefits
Relaxation and calm: Its study shows that kavalactone exerts its anti-anxiety effect by regulating the GABA neural pathway.
Promotes sleep: As a natural adaptogen, kavalactone effectively reduces anxiety-related sleep disorders, alleviates stress-induced difficulty falling asleep, and improves overall sleep quality.
Supports muscle relaxation: The core ingredient named Kawain, has natural anesthetic and relaxing effects, helping to relieve muscle fatigue and tension.
Third-party report
Product Application
0.5% Water-soluble Kavalactone:
Main Applications: Functional beverages and convenience drinks, herbal teas, etc., serving as an alcohol alternative to the popular trend of "soothing drinks."
Although the Kavalactone content is low, its special water-soluble technology and processing techniques provide beverage manufacturers with more convenient formulation options. Its enhanced solubility ensures excellent dispersibility and bioavailability in aqueous systems, and its price is higher than that of ordinary starch and proportioned extracts.
10% Kavalactone (Incompletely Water-soluble):
Main Applications: Products in capsule, tablet, and tincture forms. Including cost-effective stress-relieving formulations and relaxation products.
This specification achieves an optimal balance between cost and efficacy. It is our highly competitive standardized extract suitable for standard supplement products.
30% Kavalactone (Insoluble in Water):
Main Applications: High-end, professional-grade, and high-potency supplement lines. It is commonly used in products claiming significant relaxation and sleep-aiding effects, or in advanced nocturnal/mood-regulating formulations.
This ingredient is expensive due to the need for sophisticated extraction and concentration processes. Although the cost per milligram of Kavalactone is the highest, it allows for potent, clinical-grade formulations in small doses, making it popular among health-conscious consumers.
Reference Formulations
Relaxation Capsule (500mg/cap): Kava Extract (30% Kavalactones) - 167mg, providing 50mg of active Kavalactones per serving. Combined with Magnesium Glycinate, L-Theanine, or Lemon Balm Extract for synergistic effects.
Calming Functional Beverage Powder: Dosage calibrated to deliver 50-75mg of Kavalactones per serving. Requires dispersion agents and flavor masking due to its characteristic taste.
Sleep Support Tablet: Blended with Valerian Root Extract, Hops, and Melatonin for a comprehensive nighttime formula.
Disclaimer: These are suggested starting points. Our technical team can assist in developing customized formulas based on your specific application and target market regulations.
Formulation Considerations for Different Age Groups
Safety and dosage are paramount when formulating for different age brackets.
Adults (Ages 18-65): This is the primary and most well-researched group for Kava consumption. Formulations can utilize all three extract types:
General Wellness (10% Extract): 50-75 mg Kavalactones per serving in multi-herb blends.
Targeted Stress/Sleep (30% Extract): 100-200 mg Kavalactones per serving in standalone or focused formulas.
Functional Beverages (0.5% WS Extract): Dosed to deliver 30-50 mg Kavalactones per serving.
Older Adults (Ages 65+): Caution is advised due to potential interactions with medications and age-related changes in liver function. If formulated for this group, we recommend:
Using only the 10% extract at a conservative dosage (e.g., 30-50 mg Kavalactones per serving).
Clearly stating contraindications with medications (especially for the liver).
Positioning products with clear guidance for medical consultation prior to use.
Minors (Under 18): We do not recommend formulating Kava for children or adolescents. The market and clinical data are insufficient to establish safety profiles for this developing demographic. Product labels should clearly state "Not intended for use by persons under the age of 18."
