Kratom leaves contain two key alkaloids, mitragynine and 7-hydroxymitragynine, which interact with receptors in the brain. At lower doses, kratom is associated with stimulant-like effects, such as increased energy and alertness. At higher doses, it is linked to more sedative effects, such as relaxation and calm.

Kratom is commonly categorized into three main types based on the color of the veins in the leaves: Red Vein, Green Vein, and White Vein. Each type is believed to have distinct properties, though the effects can vary depending on the strain and individual.

There are several types of kratom extracts, each with varying concentrations and methods of extraction. Kratom powder extract is concentrated powder made by boiling and grinding kratom leaves, while kratom resin extract forms a sticky, solid substance. Liquid extracts and tinctures are highly concentrated solutions, often using alcohol as a solvent for quicker effects. Enhanced kratom combines regular powder with extract for added potency, and Full Spectrum Kratom Extract (FST) captures all alkaloids for a balanced effect. Finally, water-based extracts use water for extraction, retaining a more natural alkaloid profile.
