What Are MIT Tablets?

MIT is label shorthand for mitragynine, the most abundant alkaloid in the leaves of Mitragyna speciosa, the Southeast Asian tree commonly known as kratom. An MIT tablet is a tablet whose labeled active is mitragynine. 7Stax makes and sells MIT tablets under the name Nano Tech Mitragynine tablets.

This post covers what mitragynine is, how MIT tablets are made, what to read on the label and the batch certificate of analysis (COA), and where MIT stands legally. Nothing here is advice on use.

What mitragynine is

Mitragynine is a naturally occurring alkaloid. Among the dozens of alkaloids identified in kratom leaf, it typically accounts for the largest share of total alkaloid content by mass in dried leaf, and our page on the main kratom alkaloids covers the others.

Mitragynine can be obtained from the leaf by solvent extraction, which pulls the alkaloid out of the plant material. The concentrated extract can then be refined and formulated into finished products such as tablets.

How MIT tablets differ from kratom leaf powder

Kratom powder is dried leaf, ground fine, and it contains the plant's natural mix of alkaloids in roughly the proportions found in the leaf. An MIT tablet contains extracted mitragynine in a stated amount per tablet, so the labeled active is processed and standardized rather than ground leaf.

Our explainer on what a kratom extract is and how it differs from plain leaf powder goes into the difference in more detail.

How MIT relates to 7-OH

7-hydroxymitragynine (7-OH) is a different compound, a structural derivative of mitragynine. MIT tablets carry mitragynine as the labeled active, and they are not a substitute or replacement for 7-OH.

The milligram figures on the two kinds of label describe different compounds and are not comparable.

How MIT tablets are made

Across the category, MIT tablets combine the labeled active with common food and pharmaceutical grade ingredients that give the tablet its structure, texture and shelf stability. Ingredients often listed on MIT labels include microcrystalline cellulose, a sugar alcohol such as mannitol or sorbitol, magnesium stearate, natural flavoring, a sweetener such as sucralose or stevia, and food grade colorants.

The blend varies by brand, so the ingredient list on your pack is the one that counts.

7Stax tablets also go through a manufacturing step the brand calls Nano Tech, which reduces particle size. It is not an extra ingredient or a second active, and our comparison of Nano Tech and traditional kratom tablets explains what the term covers.

What to read on an MIT label

Label element What it tells you
Labeled active The named alkaloid in the tablet, in this case mitragynine
Milligrams per tablet The labeled amount of mitragynine in one tablet
Tablet count How many tablets are in the pack
Total labeled active per pack Milligrams per tablet multiplied by the tablet count
Ingredient list The other ingredients, such as fillers, flavors and colorants
Batch or lot number The production run, which links the pack to its COA
Testing reference Where to find the independent lab report
Manufacturer or distributor The company responsible for the product

A label that shows most or all of these is easier to check than one that leaves them out. Our guide to MIT tablet strengths and pack totals walks through how per-tablet and per-pack figures work on 7Stax packs, and the packs currently listed are on the MIT tablets collection page.

What the batch COA shows

A COA from an independent lab reports what was measured in a sample from one specific batch, and a typical report covers the following:

  • The measured amount of mitragynine per unit
  • The 7-OH result, and the MGPI (mitragynine pseudoindoxyl) result where the lab reports one
  • Whether other unlabeled alkaloids are present at meaningful levels
  • Heavy metal and microbial screening
  • Residual solvent testing, where it applies

Match the batch or lot number on your pack to the report on the 7Stax lab results page, and use our guide to reading a certificate of analysis. A COA confirms chemistry, and it is the document the federal thresholds below are read from, but it does not answer questions about state rules.

Federal status of MIT as of October 21, 2026

As of October 21, 2026, mitragynine (MIT) and kratom leaf are not federally scheduled, as stated in DEA's October 14, 2026 notice in the Federal Register. In that notice, DEA sets out its intent to temporarily place 7-hydroxymitragynine (7-OH) and mitragynine pseudoindoxyl (MGPI) in Schedule I.

The thresholds in DEA's notice can also catch a product sold as mitragynine. A solid product is caught if its 7-OH and MGPI content, alone or combined, is more than 1 mg per gram, or if the mass of mitragynine divided by the mass of 7-OH (or of 7-OH plus MGPI) is less than 100.

Either test is enough on its own, so under the same DEA notice each MIT product's position depends on its tested 7-OH content and its ratio, both read from the batch COA.

A worked example (illustration only)

These are made-up round numbers to show the arithmetic. They are not results for any 7Stax batch.

Example tablet Tablet weight Mitragynine 7-OH (no MGPI) Ratio 7-OH per gram Outcome under the notice
A 1 g 50 mg 0.25 mg 50 divided by 0.25 = 200 0.25 mg Outside both thresholds
B 1 g 50 mg 1 mg 50 divided by 1 = 50 1 mg Caught by the ratio test alone

Under DEA's threshold test, Example B would still be caught, because its ratio is below 100 even though its 7-OH content is not more than 1 mg per gram. If a COA reports MGPI, add it to the 7-OH figure for both tests.

According to DEA's notice of intent, the temporary order can be published on or after November 13, 2026, takes effect on publication and lasts two years, with a possible one-year extension. It is not yet in effect.

State rules as of October 21, 2026

As of October 21, 2026, some states restrict kratom products or 7-OH, and the federal notice states that federal action does not preempt stricter state law. These are the state rules we have checked:

State rules change often. Check your own state's current law, and do not rely on this page alone.

Frequently asked questions

What does MIT stand for on a label?

MIT is shorthand for mitragynine, the most abundant alkaloid in kratom leaf. On a tablet label it names the labeled active.

How do I check what is in my batch?

Find the batch or lot number on the pack and match it to the report on the 7Stax lab results page. The report lists the measured mitragynine and 7-OH results for that batch.

Does a COA show whether a product is legal in my state?

No. A COA reports what a lab measured in one batch. State rules change often, so check your own state's current law.
