Lab Results

We send our kava to an independent lab and publish the results. Here are both certificates in full, and what every number on them means.

The certificates

Both documents, in full.

One from the independent lab that tested the finished drink, one from our supplier for the kava extract. Pick one to read it here, or open the PDF.

Third-party certificateOpen the PDF

A certificate describes the sample that was tested, so each one here shows its date, and its lot where it has one, for you to see exactly what it covers.

Kavalactone profile

Six kavalactones, measured.

Kava has six main kavalactones. The lab measured each one in a bottle of Signature; here they are per 1.5 oz pour, largest first.

The chemotype: 423165

Each kavalactone has a number, and the chemotype lists them from most to least. Noble kava usually leads with kavain (4) or dihydrokavain (2). Ours leads with kavain, and has 4.2 times as much kavain as dihydromethysticin; our supplier’s cut-off for noble is 1.2. The supplier’s own certificate rates the extract noble too.

Everything else

What else was tested.

  • 5 tested

    Mycotoxins

    Aflatoxins B1, B2, G1 and G2, and ochratoxin A. None detected.

  • 63 tested

    Pesticides

    None detected above the lab’s reporting limits.

  • 62 tested

    Residual solvents

    Only ethanol and methanol showed up, in traces. What those traces mean is just below.

  • On the supplier’s certificate

    Heavy metals and microbes

    Arsenic 26.9 and lead 10.8 parts per billion against a 1,000 limit; cadmium and mercury under 10. E. coli, Salmonella, Staph and Pseudomonas absent.

The two traces

Ethanol and methanol, in proportion.

Of the 62 solvents on the panel, only these two came back above the lab’s reporting limit. Our kava is extracted with water alone, with no solvents anywhere in the process; the bottle tested was Signature, which is made with orange juice, and orange juice naturally carries traces of both. Here is how small the amounts are.

Ethanol · 15.0 mg per pour About 930 pours

to add up to the alcohol in one standard drink, which holds about 14 g.

Methanol · 2.78 mg per pour About 58 pours a day

just to reach the EPA’s reference dose for a 176 lb adult: the amount it considers safe to take every day for a lifetime.

From the certificate’s 339 mg/kg ethanol and 62.7 mg/kg methanol, per 1.5 oz (44.4 mL) pour. EPA reference dose for methanol: 2 mg per kg of body weight per day.
