What is green vein kratom?

Green vein kratom is leaf from Mitragyna speciosa harvested at mid-maturity, when the central vein of the leaf is green, between the younger white-vein leaf and the more mature red-vein leaf. Our Green Vein is an everyday, no-frills green-vein offering: a straightforward green available in sizes from 1 oz to 1 kg. Green is the most widely purchased vein color in the kratom category.

Where our Green Vein comes from

Our Green Vein is sourced from established Indonesian growers. Mid-maturity leaves are hand-harvested, de-stemmed, and dried indoors to preserve the green color before being milled to a fine powder.

Our Green Vein is third-party lab tested by ISO/IEC 17025 accredited laboratories for heavy metals, microbial contaminants, and mitragynine potency. A Certificate of Analysis is available on request.

Green vein vs. named green strains

Our everyday Green Vein covers the green-vein category; if you want a specific named green, we also carry:

• Green Maeng Da — Thai-origin Maeng Da lineage.
• Green Bali — named for the Bali export port.
• Green Malay — Malaysian lineage.

Green Vein Kratom Powder & Capsules

Green Vein kratom is available as loose powder and as pre-filled capsules. Powder is sold by weight in a range of sizes; capsules are pre-filled with the same milled leaf. The material is identical in both formats; only the packaging differs.

Storage

Store kratom powder in an airtight container, away from heat, light, and humidity. Kept cool and dry, Green Vein holds its color and aroma for a long time; moisture and direct sunlight are what degrade a powder over time.
