The words Sceletium tortuosum identify the plant known as kanna. They do not specify the content of a finished tablet. To understand a listing, follow the plant name through the extract description and into the serving panel.
Confirm the ingredient form
A leaf or whole-plant powder differs from a processed extract. An extract may carry its own amount and standardization statement. A finished tablet also has a total weight that includes ingredients beyond the extract. These figures serve different purposes.
Interpret the specification
If the label names mesembrine or total alkaloids as a percentage, determine what material was measured. A target for the extract is not necessarily a test of every finished tablet. The actual batch certificate can show what was measured and by which method.
Check the entire formulation
Start with serving size, then note the Sceletium amount, any alkaloid specification, other active ingredients and inactive ingredients. Read cautions and verify that supporting documents match the product and lot. A blend containing kanna should not be compared with a single-extract tablet on extract weight alone.
Human research on particular Sceletium preparations is still limited. A botanical name establishes identity, while a complete label and batch report provide the more specific information needed to compare retail products.
