Supplement interactions

Buying checklist

Product-quality considerations

Read the complete label

Look for “Kava” and its synonyms (Piper methysticum, kava-kava), the exact form, amount per serving, serving size, proprietary blends, warnings, and certification details.

Verify third-party testing

Third-party certification must be verified with the certifier or product record. A badge or seller statement alone is not proof that every lot was tested for identity, potency, contaminants, or banned substances.

Check quality details

Prefer a complete label with identity, exact amount, serving, other ingredients, allergen information, lot number, expiry, manufacturer contact, and storage instructions.
