What the AI looks for in Kava Kava Herbal Supplements

Noble cultivars: Choose noble kava, not 'tudei' or two-day varieties. Tudei varieties cause longer-lasting effects and more side effects, and Vanuatu's kava law restricts their export.
Plant part: Root or rhizome only, with no stems, leaves or peelings. Aerial parts and peelings are implicated in the hepatotoxicity concerns that led to past European restrictions.
Kavalactone disclosure: Look for the kavalactone amount on the label. Kavalactones are the active compounds, and their content varies greatly between products.

Brands that matter

Gaia Herbs: Root extracts in liquid-filled capsules.
Herb Pharm: Liquid kava extracts.
Kalm with Kava: Specialist in traditional noble kava powders.

What to avoid

Unlabeled kava powder of unknown cultivar or origin.
Combining kava with alcohol.
Daily long-term use without liver monitoring.
