Powder weight and mitragynine content are different measurements. Use the product label and the batch’s lab results to understand both before measuring a serving. This page explains our serving guidance; it does not establish a medically safe dose. Our recommended serving for plain kratom leaf powder is 3 grams of powder. At 1.5% mitragynine, that contains approximately 45 mg mitragynine. This calculation assumes the batch actually tests at 1.5%; potency can vary. For our 500 mg powder capsules, 4–6 capsules contain 2–3 grams of leaf powder. At 1.5% mitragynine, that equals approximately 30–45 mg mitragynine. This guidance does not apply to extract capsules or tablets. Our store policy limits a serving to no more than 50 mg mitragynine. That is a maximum, not a target, a guarantee of safety, or a daily allowance. Follow the lower limit if the product label specifies one. A higher-potency powder may require a smaller amount to stay within this ceiling. For reference: powder weight in grams × mitragynine percentage × 10 = mitragynine in milligrams. For example, 3 × 1.5 × 10 = 45 mg. Check the batch lab results; don’t assume every powder has the same percentage. Use a gram scale for powder rather than estimating with a teaspoon. Capsule counts apply only to the stated 500 mg fill weight. Read serving size separately from the total weight or alkaloid content of a bag, bottle, or pack. Do not use the powder or capsule amounts above for extracts. A bottle or tablet can contain multiple servings. Use the product-specific serving information and measured mitragynine content, and do not combine products to increase a serving beyond our ceiling. Milligrams of “kratom extract” are not automatically milligrams of mitragynine. Putting dry powder directly into the mouth can lead to choking or accidental inhalation. We do not recommend this method. Changing the preparation method does not change the amount of powder or mitragynine measured into it. For adults 21+ only. Some people who use kratom regularly develop dependence and experience withdrawal when stopping. Nausea, constipation, dizziness, and drowsiness have been reported. Rare but serious events, including seizures and liver injury, have also been reported in people using kratom. Some reports involve other substances, varying product composition, or incomplete information, which can make the cause difficult to determine. These limitations do not establish that kratom is risk-free or rule out its contribution to harm. Do not use during pregnancy or breastfeeding. Do not combine with alcohol, opioids, or other drugs; discuss medications and health conditions with a qualified healthcare professional. Do not drive or operate machinery after use. Kratom is not an FDA-approved treatment for pain, anxiety, opioid withdrawal, or any other medical condition. Do not increase or repeat a serving to chase an effect. If you feel unwell, stop use and seek medical advice; call 911 for a medical emergency.
