The complete hub guide to mitragynine - what the abbreviation means, the science behind the compound, how it appears across different product formats, and everything written in this series about MIT products.
If you've seen "MIT" on a kratom label, a COA, a vendor listing, or a community discussion and wanted a clear explanation of what it actually refers to - this is the starting point. If you're an experienced buyer who already knows the abbreviation and wants the specific post on buying, dosing, trust verification, or format comparison, the navigation section below links directly to each topic.
What MIT Stands For
MIT is the standard abbreviation for mitragynine - the primary active alkaloid in Mitragyna speciosa, the kratom plant. It appears in:
- Lab reports and Certificates of Analysis - where "MIT %" or "Mitragynine %" refers to the percentage of the total powder weight that is pure mitragynine
- Vendor product listings - particularly for extract products where "MIT tablets," "MIT shots," or "80% MIT extract" signal the mitragynine concentration per dose
- Community discussions - on r/kratom, forums, and review sites where informed buyers compare products by MIT content rather than brand name or strain label
- COA panel headers - alongside "7-OH" (7-hydroxymitragynine), heavy metals, and microbial results as the primary quality and safety data points
The abbreviation is shorthand adopted from analytical chemistry - the same way "CBD" shortens cannabidiol and "THC" shortens tetrahydrocannabinol. In the kratom market specifically, using "MIT" signals a buyer who is evaluating products by alkaloid content rather than marketing language.
What Mitragynine Is: The Science
Mitragynine is the most abundant alkaloid in the kratom leaf, making up approximately 60–70% of total alkaloid content. It is the compound most directly responsible for kratom's dose-dependent energy, focus, mood, and relaxation effects.
At the receptor level, mitragynine operates through three primary pathways:
Adrenergic activation - mitragynine's interaction with adrenergic receptors increases norepinephrine release, producing stimulation and wakefulness. This is the primary mechanism behind the energy and alertness effects at lower doses - the same receptor class that governs the body's alertness response, activated by mitragynine without the same cortisol-compounding effect that caffeine produces through adenosine blockade.
Serotonergic modulation - mitragynine influences serotonin (5-HT1A) pathways, contributing to the mood-elevation and motivational quality that users describe alongside the energy effect. This is the mechanism behind what users consistently describe as "directional" focus - alertness aimed at the task at hand rather than generalised stimulation.
Mu-opioid receptor partial agonism - mitragynine is a partial agonist at mu-opioid receptors (MOR), with significantly lower receptor affinity than 7-hydroxymitragynine. At energy-range doses, the MOR component is minor relative to the adrenergic and serotonergic effects. At higher doses, MOR activity becomes more prominent, shifting the effect profile toward relaxation and sedation.
The dose-response relationship is the single most important practical variable in understanding mitragynine's effects. At 1–3g of powder (or equivalent milligrams of mitragynine from extract products), the effect is primarily stimulant and focus-oriented. As dose increases, effects shift progressively toward relaxation and sedation - which is why the same compound that serves as an energy tool at low doses serves as a sleep and relaxation tool at higher doses.
Mitragynine's half-life is notably extended - research has documented mean half-lives of 43–68 hours after multiple doses, meaning it accumulates with daily use and tolerance builds faster than single-session experience suggests.
Why MIT Percentage Matters on a COA
The mitragynine percentage on a Certificate of Analysis is the single most useful quality data point in the kratom market. A 2023 study published in Drug and Alcohol Dependence found that commercially available kratom ranges from 0.11% to 2.02% mitragynine content - an 18x variance driven entirely by vendor sourcing, processing, and handling practices rather than anything inherent to the plant.
This variance matters practically because a dose measured in grams of powder is not a dose measured in milligrams of mitragynine. A 3g serving of 1.2% MIT powder delivers 36mg of mitragynine. The same weight of 1.8% MIT powder delivers 54mg - 50% more active alkaloid at identical gram weight. Users who measure by spoon or by a fixed gram weight without knowing the batch's MIT percentage are dosing inconsistently across every bag they purchase.
Quality kratom powder falls in the 1.4–2.0% mitragynine range. Below 1.2% is a low-alkaloid product regardless of strain name. Any product without a disclosed mitragynine percentage - on a batch-specific COA from an independent lab - is not providing the quality information worth paying for.
For ready-to-drink and extract products, the relevant figure shifts from percentage to milligrams per serving - a fixed number verified at manufacture. Jubi's products state this directly: 50mg per Cherry Energy Shot, 60–120mg per Lime Focus Shot, 120mg per Kratom Stick Pack.
How MIT Appears Across Product Formats
Standard leaf powder - MIT content stated as a percentage of total powder weight. Varies by batch; requires knowing the percentage to calculate the mitragynine dose per gram.
Capsules - contain kratom leaf powder at a stated gram weight per capsule (typically 0.5g). The mitragynine per capsule depends on the powder's MIT percentage - not the capsule weight alone.
MIT tablets - compressed solid forms containing a stated milligram quantity of mitragynine, extracted and standardised from kratom leaf. The per-tablet milligram figure is the relevant dose metric, verified on the batch COA. Fill weight consistency across tablets requires GMP-certified manufacturing.
Ready-to-drink shots - pre-dissolved mitragynine in a liquid format, stated as milligrams per bottle or per serving. Faster absorption than tablets; standardised per-serving dose without batch-percentage math. Jubi's Cherry Energy Shot, Lime Focus Shot, and 7OH Extract Shots all use this format.
Kratom stick packs - powder or extract mixed into a larger liquid volume (typically 16oz) and sipped gradually. Jubi's Kratom Stick Packs deliver 120mg mitragynine from White Vein Maeng Da, sipped over 30–45 minutes for a gradual sustained energy curve.
80% MIT extract - high-concentration extract powder where 80% of the extract weight is pure mitragynine. One of the highest-concentration standard mitragynine products available; requires dose reduction of 40–160x compared to equivalent gram weights of leaf powder. Distinguished from 7-OH (7-hydroxymitragynine) products, which are pharmacologically distinct and under separate regulatory scrutiny.
MIT vs. 7-OH: The Critical Distinction
The two alkaloid abbreviations that appear most often together on COAs and product labels are MIT (mitragynine) and 7-OH (7-hydroxymitragynine). They are not interchangeable - they are pharmacologically distinct compounds with different potency levels, different receptor profiles, and different regulatory status.
Mitragynine (MIT) is the dominant alkaloid - 60–70% of total leaf alkaloid content. Its MOR affinity is lower than 7-OH's, making it the lower-risk compound with a well-established energy and focus use case at appropriate doses.
7-Hydroxymitragynine (7-OH) is a minor alkaloid - less than 2% of natural leaf alkaloid content. Its MOR affinity is approximately 10 times that of morphine in concentrated form, and it is specifically the compound targeted by the FDA's July 2025 scheduling recommendation, December 2025 product seizures, and ongoing Congressional pressure for emergency DEA scheduling in 2026.
A high-MIT product and a high-7-OH product are not the same category of product. They carry different pharmacological profiles, different dependency risks, different regulatory trajectories, and different adverse-event histories. Any kratom product's COA should disclose both MIT and 7-OH content - enabling buyers to distinguish between a standard mitragynine product and one with elevated or artificially enriched 7-OH content.

Frequently Asked Questions
What does MIT stand for in kratom? Mitragynine - the primary active alkaloid in the kratom plant, abbreviated MIT in lab reports, COAs, and vendor listings.
What is a good MIT percentage for kratom powder? 1.4–2.0% is the quality benchmark for well-sourced powder. Below 1.2% is a low-alkaloid product. The 18x variance documented across commercial kratom products is driven entirely by vendor sourcing and handling - not the plant itself.
What's the difference between MIT and 7-OH? Mitragynine (MIT) is the dominant alkaloid - 60–70% of leaf content - with adrenergic and serotonergic effects at energy-range doses. 7-Hydroxymitragynine (7-OH) is a minor alkaloid with significantly stronger MOR affinity, under active FDA enforcement action since July 2025. They are pharmacologically distinct categories, not stronger and weaker versions of the same thing.
How is MIT content measured? By HPLC (High-Performance Liquid Chromatography) in an ISO 17025-accredited independent laboratory - the gold standard for alkaloid quantification. Results appear on the COA as a percentage of total powder weight (for powder products) or milligrams per serving (for extract and ready-to-drink products).
Why do some products say MIT tablets? MIT tablets are compressed solid-form products containing a stated milligram quantity of mitragynine - extracted and standardised from kratom leaf. The "MIT" label distinguishes them from kratom leaf powder capsules (which state gram weight, not mitragynine milligrams) and from 7-OH tablets (which use a pharmacologically distinct compound).
