From the basics of what mitragynine actually is, to why extract standardization matters, to how 80% mitragynine tablets fit into a serious kratom routine - everything you need to know in one place.
The kratom market has matured considerably over the past decade. What started as a category dominated by bulk powder sold in unmarked bags has evolved into a space with genuine product differentiation, meaningful quality tiers, and increasingly sophisticated users who want to understand what they're actually consuming rather than just hoping for the best.
Nowhere is this evolution more visible than in the extract segment - and nowhere in the extract segment is the conversation more active than around high-percentage mitragynine standardization. Specifically, around products standardized to 80% mitragynine content.
If you've seen "80% mitragynine extract" on a product label and wondered what that number actually means, whether it matters, how it compares to other kratom products you've tried, and whether it's appropriate for your specific needs - this guide was written to answer those questions honestly and completely.
We're going from the basics - what mitragynine actually is and how it works - through the intermediate territory of extraction and standardization, all the way to advanced considerations about dosing, tolerance, and how high-percentage extract fits into a thoughtful long-term kratom practice.
Start at the Beginning: What Is Mitragynine?
Mitragynine is the primary active alkaloid in kratom (Mitragyna speciosa) - the tropical tree native to Southeast Asia whose leaves have been used for centuries as a natural tool for managing energy, focus, mood, and physical endurance.
An alkaloid is a naturally occurring nitrogen-containing compound produced by a plant as part of its chemistry. Alkaloids are the active components behind the effects of many botanicals that humans have used throughout history - caffeine in coffee, morphine in opium poppies, quinine in cinchona bark, and dozens of others across thousands of plant species. Kratom produces dozens of alkaloids, but mitragynine is the dominant one - typically making up 60-70% of the total alkaloid content in dried kratom leaf.
Mitragynine's effects depend heavily on dose. At lower doses, it primarily interacts with adrenergic receptors (producing stimulating, energizing effects) and serotonin receptors (producing mood elevation). At moderate to higher doses, it increasingly engages opioid receptors, particularly mu-opioid receptors, producing relaxing, pain-relieving, and sedating effects.
This dose-dependent effect profile is what makes kratom unusually versatile as a botanical - the same plant can function as a morning energy and focus tool at one dose range and an evening relaxation tool at another. The strain (White, Green, or Red vein) affects which end of this spectrum is more pronounced, but all mitragynine-based kratom products operate within this fundamental dose-response framework.
Standard kratom powder contains mitragynine in its natural concentration within the leaf - typically 1-2% of the dry weight of high-quality Maeng Da powder. This means a 5-gram dose of quality kratom powder contains roughly 50-100mg of mitragynine. Everything else in that 5 grams is plant fiber, other minor alkaloids, and various other plant compounds.
What Is Kratom Extract? The Extraction Process Explained
The natural question after understanding whole-leaf kratom powder is: what happens if you remove the plant material and concentrate just the active compounds?
That process is extraction - and it's been practiced with botanicals for centuries, from the distillation of essential oils to the concentration of herbal tinctures to the manufacture of pharmaceutical drugs from plant-derived compounds.
Kratom extraction typically involves one of several methods:
Water extraction (aqueous extraction) dissolves the water-soluble alkaloids from the kratom leaf into hot water, then removes the plant material and evaporates the water to leave a concentrated alkaloid residue. This method captures mitragynine and other water-soluble alkaloids effectively but may not capture all of the plant's bioactive compounds.
Alcohol extraction (ethanol extraction) uses ethanol as the solvent, which dissolves a broader range of compounds including both water-soluble and alcohol-soluble alkaloids. Many practitioners prefer this method for full-spectrum extracts because it captures more of the plant's complete alkaloid profile.
Cold water extraction uses cold rather than hot water, which changes the solubility profile of the compounds extracted and, proponents argue, better preserves the natural alkaloid ratios and avoids heat degradation of sensitive compounds. This is the method Jubi uses across its kratom product lineup.
CO2 supercritical extraction uses pressurized carbon dioxide as a solvent - a pharmaceutical-grade method that produces very clean, pure extracts but requires expensive equipment and is more common in high-end cannabis and hemp extraction than in kratom production.
The result of any extraction process is a concentrated material containing a higher proportion of active alkaloids per gram than the original leaf material. A 10:1 extract, for example, contains the alkaloids from roughly 10 grams of leaf material concentrated into 1 gram of extract.
Understanding Standardization: What "80% Mitragynine" Actually Means
Here's where the conversation gets more specific - and more important for anyone evaluating extract products.
"Extract" tells you that concentration has occurred. It doesn't tell you how much, or specifically what has been concentrated. A "10:1 extract" tells you the concentration ratio but not the actual alkaloid content. A product could be a 10:1 extract from low-quality leaf that started with 0.5% mitragynine, or from high-quality Maeng Da that started with 1.8% mitragynine - the ratio is the same but the actual mitragynine content is very different.
Standardization solves this problem by specifying the actual percentage of a target compound in the final extract, regardless of the starting material or concentration ratio.
When a product says "80% mitragynine extract," it means that 80% of the extract's total weight is pure mitragynine alkaloid. In practical terms: a 150mg tablet of 80% mitragynine extract contains 120mg of actual mitragynine. This is a precise, verifiable, meaningful number - and it's the number that matters for dosing, for consistency, and for safety.
Compare this to whole-leaf powder, where mitragynine content might be 1-2% of the dry weight. A 150mg serving of whole-leaf powder contains 1.5-3mg of mitragynine. A 150mg tablet of 80% extract contains 120mg. The difference is not just significant - it's the difference between two categorically different products that require completely different approaches to dosing.
This is why high-percentage standardized extracts are not simply "stronger kratom powder." They are a different format with different dosing requirements, different onset characteristics, and different appropriate use cases.
The 80% Standard: Why This Percentage?
Among the various standardization levels available in the kratom extract market - 40%, 50%, 60%, 70%, 80%, and beyond - 80% has emerged as a significant threshold for several reasons.
Purity ceiling: Producing kratom extract at 80% mitragynine standardization requires sophisticated, multi-stage extraction and purification processes. Below 80%, the technical demands are more modest - relatively straightforward extraction can produce extracts in the 40-60% range. At 80%, you're approaching the upper end of what standard commercial extraction processes can produce while maintaining a reasonable yield and cost structure.
Effect concentration: At 80%, the mitragynine content is high enough that meaningful effects are achievable at relatively small tablet sizes - 150mg tablets containing 120mg of mitragynine, for example. This makes the format genuinely convenient without requiring tablets so large they become difficult to take.
Full-spectrum vs. isolated: At 80% mitragynine, the extract still contains 20% of other compounds - minor alkaloids, plant compounds, and various co-factors that many kratom users believe contribute to the overall experience. Products that go beyond 80% toward 95%+ mitragynine isolation are increasingly approaching isolated alkaloid territory, which some users find produces a less nuanced, less satisfying experience than products that retain some of the plant's complexity.
Market establishment: 80% mitragynine has become a recognized standard in the kratom extract market - a level that experienced users understand and that product developers can reliably target and verify through laboratory testing.
How 80% Mitragynine Extract Is Made: The Production Reality
Producing consistently high-quality 80% mitragynine extract requires capabilities that most kratom operations - particularly small vendors and overseas operations without quality infrastructure - simply don't have.
The process typically involves:
Starting material selection: The quality of the final extract is limited by the quality of the starting material. Producing consistent 80% standardized extract requires beginning with consistently high-alkaloid leaf - typically premium Maeng Da from trusted cultivators who can provide consistent alkaloid profiles across harvests.
Initial extraction: The dried, ground leaf material undergoes primary extraction - typically using ethanol or water - to pull alkaloids from the plant fiber into solution. This produces a concentrated alkaloid-rich liquid.
Purification stages: The initial extract is then subjected to multiple purification stages - precipitation, filtration, chromatography in more sophisticated operations - that progressively increase the mitragynine percentage by removing non-alkaloid compounds and minor alkaloids.
Potency verification: At each stage of purification, quality operations test the intermediate material to verify alkaloid content and adjust the process accordingly. The final extract is tested to confirm it meets the 80% standardization target.
Tableting and encapsulation: The verified 80% extract powder is then combined with excipients (binding agents, fillers, flavorings for chewable tablets) and formed into tablets using pharmaceutical tableting equipment. GMP-compliant tablet manufacturing produces consistent fill weights and therefore consistent per-tablet alkaloid content.
Final batch testing: Every finished batch is tested by an independent third-party laboratory to verify that the labeled 80% mitragynine content is accurate and that the product meets safety standards for contaminants.
This is an elaborate, expensive, technically demanding process. Products that claim 80% mitragynine content without third-party testing to verify it should be treated with appropriate skepticism - the financial incentive to cut corners exists, and without published lab results, there's no way to know whether the label reflects reality.
Drink Jubi's Advance 80% Mitragynine Extract Chewable Tablets are manufactured in a GMP-compliant facility in the United States, and third-party testing is part of the production process. For a product at this potency level, that verification matters enormously.
What Does 80% Mitragynine Extract Feel Like? The Effect Profile
For experienced kratom users whose primary reference point is whole-leaf powder or standard mitragynine shots, the 80% extract experience is qualitatively different enough to warrant specific description.
The onset: Chewable 80% extract tablets - when chewed properly, allowing the material to dissolve and begin absorbing through the oral mucosa - produce effects faster than swallowed capsules. Most users notice the beginning of effects within 20-30 minutes, with the full effect profile developing over 45-60 minutes.
The energy and focus: At appropriate doses in the energy-and-focus range, 80% mitragynine extract produces a pronounced version of the white vein kratom experience - clear cognitive engagement, elevated motivation, sustained energy, and mood support that makes demanding work feel more tractable. The clarity and directness of the effect is often described as cleaner than whole-leaf products - less botanical complexity, more direct mitragynine expression.*
The physical component: Many users report a pleasant physical ease alongside the mental effects even at focus-and-energy doses - a reduction in the background physical tension that accumulates through demanding days, without the sedation that would impair performance.*
The duration: Effects from 80% mitragynine extract tablets typically last 4-6 hours at appropriate doses - consistent with the duration of whole-leaf kratom effects, which reflects the fact that it's the same alkaloid at a higher concentration rather than a fundamentally different compound.*
What it's not: 80% mitragynine extract is not 7-hydroxymitragynine. Mitragynine at high concentration produces an amplified mitragynine experience - energizing and focus-enhancing at lower doses, relaxing at higher doses. It doesn't produce the specifically opioid-forward effect profile of 7-OH. Experienced users who've tried both describe the 80% mitragynine experience as the best version of a familiar effect, while 7-OH produces something qualitatively different.*
Dosing 80% Mitragynine Extract: The Critical Recalibration
This section is the most practically important part of this guide for anyone considering 80% mitragynine extract for the first time. Read it carefully.
The fundamental principle: Your whole-leaf dose does not translate to 80% extract.
Here's the math that makes this concrete:
A typical moderate-dose whole-leaf kratom user might take 4 grams of quality Maeng Da powder. At 1.5% mitragynine content (typical for quality Maeng Da), that's 60mg of mitragynine.
A 150mg tablet of Jubi's 80% mitragynine extract contains 120mg of mitragynine.
One tablet of 80% extract contains twice the mitragynine as a moderate-dose whole-leaf session. And the tablet is presented as a single unit - the natural cognitive tendency is to treat it as one serving. Which it is, in terms of the physical unit - but not in terms of what your body has been calibrated to handle.
Jubi's recommended serving for the Advance 80% Mitragynine Chewable Tablets is one quarter to one half tablet - which delivers 37.5-75mg of mitragynine. This is the appropriate starting range even for experienced kratom users who've consumed regular kratom products for years.
A practical first-use dosing protocol:
On your first session with 80% mitragynine extract, take one quarter tablet (37.5mg mitragynine). Set a timer for 60 minutes. During that time, don't take anything else and don't try to assess whether it's "working" at the 20-minute mark. When the timer goes off, genuinely assess your experience. Note where you are on the spectrum from "insufficient effect" to "exactly right" to "more than intended."
On your second session, use that assessment to inform your starting point. If one quarter tablet was clearly insufficient, try one third to one half tablet. If it was appropriate, repeat and refine. If it was more than intended - and for some users with lower mitragynine sensitivity, even a quarter tablet will be meaningful - take a rest day and reconsider your approach.
The goal of the first two to three sessions is calibration, not optimization. You're gathering data about your individual response to this specific product. That data is what allows you to optimize confidently rather than guessing.
Six Flavors of Jubi's 80% Mitragynine Tablets: Why Flavor Matters at This Potency
One of the specific challenges of high-potency extract tablets is that they're typically chewable - the chewable format's faster onset makes it preferable to swallowed tablets for precise dose management. And chewing 80% mitragynine extract without effective flavoring produces an intensely bitter, genuinely unpleasant experience.
Jubi's Advance 80% Mitragynine Extract Chewable Tablets are available in six flavors specifically because making the chewing experience genuinely pleasant isn't cosmetic - it's functional. A tablet you look forward to taking is a tablet you'll actually take consistently, at the right times, in the right amounts. A tablet you dread taking gets skipped, taken at the wrong times, or swallowed whole to avoid the taste - undermining both the consistency and the onset characteristics.
The six flavors:
Apple - Crisp, tart, and clean. The apple profile's acidity provides effective bitterness masking through flavor competition rather than just sweetness layering. The clean finish makes it a good choice for users who don't want a lingering flavor experience.
Cotton Candy - The most unexpected effective flavor in the lineup. High-concentration mitragynine extract is intensely bitter; cotton candy's airy sweetness is a genuinely effective counterpoint. Consistently surprised first-time users who expected to find it too sweet discover that the flavor balance works remarkably well.
Fruit Punch - The most familiar and broadly appealing option. The classic fruit punch profile - tropical, citrus-adjacent, boldly sweet - has enough flavor presence to hold its own against concentrated extract. The first choice for users who want something universally approachable.
Pineapple - The most technically effective flavor for bitterness masking. Pineapple's natural acidity and tropical sweetness work on both the bitter and sour dimensions of the extract's flavor simultaneously. A consistent top performer among users who've tried multiple flavors.
Watermelon - The lightest, most refreshing option. For users who want effective flavoring without intensity, Watermelon provides pleasant taste without demanding your attention. The summer-forward profile is genuinely enjoyable.
Original - Minimally flavored, closest to the extract's natural character. For experienced kratom users who are comfortable with botanical flavors and prefer the most direct relationship with the extract itself. Not for everyone, but exactly right for a specific subset of users who find flavored products distracting.
80% Mitragynine vs. Other Extract Products: Making Sense of the Market
The kratom extract market is full of products with numbers on their labels - 10:1, 50x, 45% full spectrum, 80% mitragynine, 7-OH 50mg - that most consumers haven't been given the context to interpret. Here's a comparison that makes the landscape more navigable:
Whole-leaf powder (1-2% mitragynine): The baseline. Traditional format, maximum botanical complexity, lowest mitragynine concentration, most forgiving dosing. Starting point for new users; preferred format for users who value botanical completeness and custom dosing flexibility.
Standard kratom shots (50-120mg mitragynine per bottle): Liquid extract format at mid-range concentration. Fast absorption, pre-measured, convenient. The Jubi Cherry Energy Shot (50mg per bottle) and Lime Focus Shot (120mg per bottle) are examples. Better for daily use at established doses than for high-potency extract applications.
Kratom stick packs (120mg mitragynine per stick): Powder mix format at similar concentration to standard shots. More flexible than shots in terms of volume and concentration control. Good for regular users who prefer mixing into water over liquid shots.
80% mitragynine extract tablets (120mg mitragynine per 150mg tablet): High-purity standardized extract at significantly higher mitragynine concentration per unit than any of the above formats. For experienced users who want the most potent mitragynine-based experience available in a clean, tested, precisely dosed tablet format.
7-OH extract products (10-100mg 7-OH per serving): A completely different alkaloid - 7-hydroxymitragynine rather than mitragynine. Different effect profile (more opioid-forward, more relaxation-specific), higher potency per milligram than mitragynine, higher dependence potential. Not a replacement for 80% mitragynine extract - a different product for different purposes.
Who Should (and Shouldn't) Use 80% Mitragynine Extract
Appropriate for:
Experienced kratom users who have a clear, established understanding of their response to mitragynine at various dose levels and are specifically looking for the precision, potency, and convenience that standardized high-percentage extract tablets provide.
Users who have built tolerance to lower-potency kratom products and are seeking a format that can deliver meaningful effects at smaller physical quantities.
People who specifically value precise, verified dosing - where knowing that each quarter-tablet contains exactly 37.5mg of verified mitragynine is meaningful to them rather than incidental.
Users who want the cleanest, most direct mitragynine experience - minimal plant material, maximum alkaloid expression, precisely measured.
Not appropriate for:
Anyone new to kratom. The 80% extract is not a starting point for kratom exploration. Jubi's shots, stick packs, or standard Maeng Da capsules are far more appropriate entry points.
Users who haven't established their mitragynine sensitivity through experience with lower-potency products. Without that reference point, calibrating 80% extract dosing is genuinely difficult.
Anyone prone to tolerance escalation or difficulty moderating their supplement use. High-potency extracts accelerate tolerance development faster than whole-leaf products. Users who tend toward escalating doses over time are better served by formats that provide more natural limits on intake.
People seeking the 7-OH effect profile. 80% mitragynine extract is not a path to 7-OH's specific effects - it produces an amplified mitragynine experience, which is categorically different.
Managing Tolerance With High-Percentage Extract: The Advanced Practice
Tolerance management becomes more important - and more challenging - with high-potency extract products than with whole-leaf kratom. The concentrated alkaloid delivery means the opioid receptor system that drives tolerance development receives a more intense signal per use, accelerating the downregulation process.
Experienced users of 80% mitragynine extract who maintain long-term effectiveness share several consistent practices:
Strict usage frequency limits. Most experienced high-percentage extract users do not use daily. Three to four times per week is a common maximum, with some users maintaining two to three uses per week as their sustainable upper limit.
Rotation with lower-potency products. Using Jubi's standard kratom shots, stick packs, or Maeng Da capsules on the days between 80% extract uses maintains the botanical practice without the concentrated receptor stimulation that accelerates tolerance in the extract-specific receptor populations.
Dose discipline. Finding your effective dose and maintaining it - not chasing escalating doses as the first response to reduced effects. When the current dose starts feeling less effective, the right response is a break, not an increase.
Planned tolerance breaks. One week off every four to six weeks is a commonly cited practice among experienced users - a period long enough for meaningful receptor resensitization, built deliberately into the routine rather than taken reactively when things have already escalated.
Strain rotation within the extract category. Using the Advance tablets alongside different standard strain products keeps the overall alkaloid profile varied in ways that slow tolerance development compared to using a single product exclusively.

Frequently Asked Questions
Is 80% mitragynine extract safe? For experienced adult kratom users approaching it with appropriate dose awareness, responsible use frequency, and healthcare provider consultation if they take medications, 80% mitragynine extract has the same fundamental safety profile as other mitragynine-based kratom products - amplified by its concentration. The risks that exist with any kratom product (tolerance, dependence potential, drug interactions) are more pronounced with high-potency extract than with whole-leaf products and require correspondingly more careful management.
How does 80% extract compare to "full spectrum" extracts? Full-spectrum extracts aim to preserve the complete alkaloid profile of the kratom leaf in concentrated form. 80% mitragynine standardization involves more aggressive purification that specifically concentrates mitragynine while reducing the proportion of minor alkaloids. Full-spectrum extracts may provide a more balanced, botanically complete experience; 80% standardized extracts provide a more direct, concentrated mitragynine experience. Neither is objectively better - they serve different preferences and use cases.
Can I build tolerance to 80% mitragynine extract faster than to regular kratom? Yes - the concentrated alkaloid delivery produces more rapid tolerance development than whole-leaf products at comparable effect levels. This is one of the primary reasons responsible use frequency matters more with high-percentage extracts than with standard kratom products.
Should I start with 80% extract or with standard kratom products? Standard products - Jubi's shots, stick packs, or Maeng Da capsules - are the appropriate starting point for anyone new to kratom. 80% extract is for users who already understand their mitragynine response from experience with lower-potency products.
