A kanna tablet can display several numbers that describe different parts of the product. One may be the weight of the tablet, another the amount of Sceletium extract, and a third an alkaloid percentage. Reading them as though they were the same measurement makes product comparisons misleading.
First establish the serving
Find the number of tablets per serving and the extract amount for that serving. A 150 mg extract claim cannot be compared directly with a 150 mg whole-tablet weight. The latter includes flavoring and other materials.
Then examine any standardization
A mesembrine percentage refers to a stated share of an extract or to a measured result, depending on the wording. It is not another way to state the extract weight. Check whether the label refers to mesembrine alone or total alkaloids, and whether a laboratory report measures the actual batch.
Look beyond the headline
Two kanna products can contain different sweeteners, flavors or additional active ingredients. Compare the complete panels and warnings. A certificate of analysis is helpful when its batch number matches the package and its tests address the content claimed on the label.
Put serving size, extract amount, percentage basis and other ingredients into separate columns. This simple comparison is more reliable than ranking products by the largest number on the front. Research on Sceletium is ongoing and does not establish a guaranteed effect for any particular tablet.
