Kanna tablets can look similar on a product page while their labels describe different things. A large milligram number may refer to the whole tablet, a serving, or the extract alone. Compare products only after finding the basis for each number.
Begin with the serving
Read how many tablets make one serving and how many servings the package contains. Then identify the amount of kanna extract per serving. Tablet weight includes other ingredients and should not be mistaken for the quantity of Sceletium extract.
Extract weight and standardization
A statement such as “150 mg extract” gives a mass. A percentage of mesembrine or total alkaloids is a separate specification. Neither number, by itself, establishes the amount of every alkaloid in the final tablet. If a percentage is shown, check whether it describes the extract specification or a measurement of the finished batch.
Read the rest of the panel
Flavor, sweeteners, binders and other active ingredients can differ between tablets with similar kanna claims. Check the ingredient list and warnings, especially if comparing a single-extract tablet with a combination formula. A batch-matched certificate of analysis can support identity and measured content; a generic document cannot verify every package.
The most useful comparison places extract amount, percentage basis, serving size and complete formula side by side. Research on Sceletium remains limited, so a label should not be read as a guarantee of a particular mood or cognitive effect.
