You’ll also notice that kratom strains are usually classified by a location or region. The main varieties you’ll see are: Maeng Da Bali Indo Malay Thai Borneo This can be misleading as nearly all of the kratom in the United States is grown and exported from Indonesia.  As far as our “kratom strains” go, we categorize our strains by alkaloid content. Signature Reserve is our most alkaloid rich variety and is guaranteed to test for 1.4% mitragynine at minimum. The next “tier” is Maeng Da kratom, and then Bali kratom powder/Thai kratom. The Maeng Da will generally test higher for mitragynine.    THE TRUTH ABOUT KRATOM VEINS AND STRAIN ORIGINS While the classifications of strains and vein color that we mentioned above are commonly used in the Kratom community, it’s important to take this information with a grain of salt. Because of the lack of regulation and quality control in many countries where kratom is harvested (mainly Indonesia), there is very little oversight on how strains are specifically categorized. Some scientists believe that kratom trees in different regions may produce genetically different kratom, but there isn’t substantial evidence proving this theory. This means that Kratom sellers have to take the word of their suppliers as to which strains are which, without consistent ways to verify that information. When buying kratom, look for brands that use good manufacturing practices (GMP) and brands that are transparent about the source of their products. Our goal at Super Speciosa is to be as transparent as possible with our customers and give you the necessary information you need to choose which type of kratom is right for you.  To read more about the truth of kratom strains, click here.
