What's a standard kava serving?

A standard serving of kava is measured by kavalactone content, not by volume. Two drinks of the same size can differ severalfold in strength depending on how they were made, which is why volume alone tells you very little.

• Strained root — one shell or cup; strength varies between preparations
• Instant kava — 1–2 heaped teaspoons in water; depends on the product's concentration
• Single-serve shot — one pack, taken neat; the amount is stated on the pack
• Kava spirit — a 1.5 fl oz pour; the amount is stated per serving

Kavalactones are the unit that matters. They are the active compounds in kava root, and the amount in a serving is what determines how pronounced and how long-lasting the effect is. A large drink made from weak preparation can contain fewer kavalactones than a small measured shot.

Traditional preparation is inherently variable. Kneading root powder in water extracts an amount that depends on the root, the ratio, the water temperature and how long it was worked. That variability is normal, and it is the main practical difference between traditional kava and a standardized product.

Standardized products state the figure. Kavayn's serving figures are stated per product: a 1.5 fl oz pour of Noble Kava Spirits contains 350 mg of kavalactones, and a single Snap Pack contains 250 mg. Each format is measured for its own occasion — a pour to build a drink around, a pack to take with you.

Why the number is worth knowing. Once you know what a serving contains, you can repeat it. That is the difference between knowing how kava affects you and guessing each time — and it is the reason measured servings exist.

Always follow the serving instructions on the product you have. Concentrations differ substantially between brands and formats, and a serving of one is not a serving of another.
