Alkaloid Profile: A Sumatran Signature
Red Sumatra registers 1.37% total alkaloids, with mitragynine at 0.85% accounting for 61.7% of the total. The secondary alkaloid ratios tell the story of Sumatra's different growing environment: paynantheine at 0.15% and speciogynine at 0.12% show the same proportional balance as Borneo reds, but speciociliatine at 0.26% (19.1% of total alkaloids) gives Red Sumatra one of the highest speciociliatine ratios in our range. Research suggests speciociliatine has a distinct binding profile from mitragynine due to its different stereochemistry. The volcanic soil composition of Sumatra, enriched by centuries of volcanic activity, likely contributes to these regional alkaloid differences.
Tested and Ready to Ship
Less widely available than our Borneo reds because fewer Sumatran farms meet our quality standards. Lab-tested for alkaloid content and heavy metals, gamma-sterilised after vacuum packaging. Also available as capsules. Explore our full red kratom collection.
