What the milligram on the pack means

Every Smart Addicts kratom pack states a figure in milligrams of mitragynine per piece. This is what that figure is, how it is measured, and why we print it instead of a weight of leaf.

Mitragynine is the alkaloid, not the plant

Kratom is the leaf of Mitragyna speciosa, a tree in the coffee family that grows in Southeast Asia. The leaf contains dozens of alkaloids, and the one present in the largest amount is mitragynine. When a laboratory tests a batch of kratom, mitragynine is the compound it measures to confirm identity and to state potency, because it is the marker the industry and the regulators have settled on.

A weight of leaf tells you how much plant material went into a piece. It does not tell you how much mitragynine is in it, because the alkaloid content of leaf varies with the tree, the season, the harvest and the drying. Two grams of one harvest and two grams of another can differ by a wide margin. A milligram figure for the alkaloid itself removes that guesswork.

How the figure is measured

The number on the pack comes from the batch report, not from a recipe. Each production run is sampled and sent to a laboratory, which runs a potency test, typically by high performance liquid chromatography. The result is a concentration of mitragynine in the sample, which is then expressed per piece: 25 mg per gummy on the Kratom Addicts gummies, 200 mg per tablet on the chewable tablets. The same report checks the piece against the limits for heavy metals and microbial contamination, and confirms that 7-hydroxymitragynine, a minor alkaloid, sits below the threshold stated on the report.

Why per piece and not per pack

You take one piece at a time, so one piece is the unit that matters. The total for the pack is printed as well, because it is a quick way to compare a five pack with a ten pack, but the per piece figure is the one we ask you to read first. It is the same on every product page, in the comparison table and on the label, and it is the figure the batch report supports.

Where to check it

Turn the pack over. The lot number sits next to the best before date. Send us that lot number and we send you the report for that run, with the potency result on it. The process is described on the lab results page, and how to read a certificate of analysis walks through each line of a report.
