Lyophilized Thai Kratom Extract is finally back... This was a fan favorite, best seller back in 2005 when we first got started, but was discontinued due to the time consuming multistep process required to produce it. Lyophilized Thai Kratom Extract is made from an organic extraction process and then filtered to remove all impurities such as fats and chlorophyll. From there it is Lyophilized, or freeze dried which removes all moisture and produces one of the purest Kratom products on the market today.
