The Mitragyna Speciosa leaves are harvested, dried, and crushed to get them into powder form. Typically the kratom is marketed in powder form or packed in capsules. However, leaves are also used to produce kratom liquid extract also known as kratom extract shots.
Most often liquid kratom is combined with different additives to create different effects and flavors. You can find kratom liquid extracts with varying potency, additives, and kratom veins.
You can think of kratom liquid shots as a commonly available 5-hour energy shot. These drinking shots contain additional ingredients to kick off an energy boost.
