TL;DR
- Mitra-9 makes canned kratom seltzers with 45 mg of mitragynine extract per can, zero sugar, zero calories.
- Seven flavors including dragon fruit, tangerine, raspberry lime, watermelon, and tropical.
- Pricing runs $29.99 for a 4-pack up to $144.95 for 24 cans, so roughly $6 to $7.50 per can.
- Small-batch third-party lab testing for contaminants, per the brand.
- Our verdict: one of the most polished kratom drinks in the cooler, priced like a cocktail. Great gateway format, and there are stronger-value options once you know you like the category.
What Mitra-9 Is
Mitra-9 took the hard seltzer playbook and pointed it at kratom. Slim cans, fruit flavors, bubbles, zero sugar, and a measured dose of mitragynine extract in every can. Where Feel Free went the 2 oz tonic-shot route, Mitra-9 bet that people want their botanicals in a format that feels like a Friday drink.
Smart bet, honestly. The canned format solves the two things people hate most about traditional kratom: the taste of the powder and the guesswork of dosing it. We build drinks at GudTonics for the same reasons, so consider this a review from inside the category, biases disclosed up front.
Strength: The 45 mg Question
Every Mitra-9 seltzer carries 45 mg of mitragynine extract. What does that number mean in practice?
A typical serving of plain kratom powder (2 to 3 grams of decent leaf) delivers somewhere around 25 to 45 mg of mitragynine depending on potency. So one can sits at the strong end of a standard single serving. Enough that most people clearly feel it, mild enough that a can doesn't flatten a newcomer the way extract shots can.
The part we respect: the number is printed and consistent. You know exactly what you're drinking, can after can, which is more than powder scoopers can say. One can and see how you feel is the obvious starting protocol, and the carbonation means it lands a bit quicker than powder on a full stomach.
Flavors, Ranked by the Internet
Seven flavors circulate: dragon fruit, tangerine, raspberry lime, tropical, watermelon, and a couple of rotating others. Scroll the reviews and a hierarchy emerges. Dragon fruit and raspberry lime collect the most love. Tangerine splits the room. Watermelon has a loyal minority.
Taste-wise, expect a light, dry seltzer with mild fruit and a faint botanical bitterness underneath (kratom never fully hides). One BevNET-style tasting note kept coming up in community reviews: "the best kratom drinks I have ever had," and while that's one enthusiastic customer, the general consensus agrees the flavor engineering is above category average. The variety pack exists precisely so you don't have to commit blind, and it's the right first order.
Pricing and Where the Value Lands
| Pack size | Price | Per can |
|---|---|---|
| 4-pack | $29.99 | $7.50 |
| 12-pack (variety) | mid-tier pricing | ~$6.50 |
| 24-pack | $144.95 | ~$6.04 |
Six to seven fifty per can. That's craft-cocktail money for a botanical seltzer, and it's the main criticism you'll hear from otherwise happy customers. Compare formats: the same 45 mg of mitragynine as powder costs under a dollar, and as a small-batch tonic somewhere in between. You're paying for the can, the carbonation, the flavor work, and the convenience. Whether that trade is worth it depends entirely on how much you value not tasting kratom powder (for many people: a lot).
Lab Testing and Transparency
Mitra-9 says its mitragynine extract goes through small-batch third-party lab testing covering chemicals, heavy metals, and contaminants. The alkaloid content is printed per can, which we've established is the single most useful number a kratom drink can share.
Room to grow? Batch-specific certificates posted per product would close the loop completely. The claim structure is solid though, and printing a hard mitragynine number puts them ahead of most of the cooler. The drinks are also gluten-free, vegan, and naturally flavored, for those keeping score.
What Drinkers Report
Common threads across community reviews:
- The effect: a clean, social lift that arrives in 20 to 40 minutes and fades over a few hours. Repeatedly described as more predictable than powder.
- The format win: people who quit powder over taste come back to the category through cans. Happens constantly.
- The gripes: price per can, and a wish for a stronger option from heavy users (a temptation worth resisting, frankly; the measured dose is the feature).
Anything about dependence? Same as every kratom product: daily multi-can habits are where problems start. Measured cans make moderation easier to track, not automatic.

- Single strength only
Mitra-9 vs Feel Free vs GudTonics
| Criteria | Mitra-9 | Feel Free | GudTonics |
|---|---|---|---|
| Format | 12 oz carbonated can | 2 oz tonic shot | Bottled kava + kratom tonic |
| Botanicals | Kratom extract only | Kava + leaf kratom | Kava + kratom extract |
| Stated strength | 45 mg mitragynine/can | Not published | Published per bottle |
| Price per serving | $6.00 to $7.50 | $4 to $6 (1 oz serving) | Small-batch mid-range |
| Best for | Seltzer fans, precise dosing | Ubiquity, quick shot format | Flavor-first kava-kratom blends with full transparency |
Three different answers to the same question. Mitra-9 wins on dose clarity and drinkability. Feel Free wins on being available everywhere. We built GudTonics for the drinker who wants the kava-kratom blend AND the published numbers, because we didn't think anyone should have to choose.
Seltzer vs Powder vs Shots: The Format Math
Same alkaloid, three delivery systems, wildly different experiences and price tags. Here's the honest comparison every kratom drinker eventually does on a napkin.
| Format | Typical mitragynine per serving | Cost per serving | Onset | The catch |
|---|---|---|---|---|
| Plain powder (toss and wash or tea) | 25-45 mg (2-3 g leaf) | $0.30 to $1 | 30-60 min | The taste. Also dosing depends on your scale and your honesty |
| Kratom seltzer (Mitra-9) | 45 mg, printed | $6 to $7.50 | 20-40 min | Price. You're paying 10x powder for the can and the flavor |
| Extract shots (MIT45 class) | Varies wildly, often much higher | $8 to $20 | 15-30 min | Potency ceiling. Easiest format to overdo, fastest tolerance |
Where does a kava-kratom tonic fit? Between seltzer and shots on strength, closer to seltzer on experience, with kava adding the rounded base note neither pure-kratom format has. Different tool, different job.
The format you choose quietly shapes your habits, too. Powder's friction (the taste, the scale, the mess) is accidentally protective. Cans remove friction, which is wonderful for enjoyment and worth compensating for with a little intentionality. Buy the 4-pack, not the 24-pack, until you know your pattern.
When a Can Makes Sense (and When It Doesn't)
Reach for a seltzer when: you're new and want a measured, taste-friendly introduction; you're replacing a happy-hour drink and want something social in your hand; you're traveling and a scale plus a bag of green powder would raise eyebrows; or you simply never made peace with the flavor of leaf (nobody blames you).
Skip the seltzer when: you're a daily high-volume user, because the per-can economics will quietly eat a paycheck; you want fine-grained dose control below 45 mg; or you're chasing intensity, in which case no carbonated product is built for you and the honest answer is to examine the chase itself.
One more scenario worth naming: the fridge-stocking trap. A cooler full of pleasant, sugar-free, great-tasting kratom drinks makes "one more can" the path of least resistance. Treat the daily cap the way the label means it, and keep count on the honor system you'd actually honor.
FAQ
How much kratom is in a Mitra-9 seltzer?
45 mg of mitragynine extract per can, comparable to a solid single serving of traditional powder.
How many Mitra-9 cans should I drink?
Start with one and wait at least an hour before deciding you need anything more. The brand and common sense agree: don't stack cans, don't mix with alcohol, and keep it out of your daily-habit rotation.
Does Mitra-9 taste like kratom?
Barely. There's a faint botanical bitterness under the fruit, but it's a seltzer first. Dragon fruit and raspberry lime hide it best according to most reviewers.
Is Mitra-9 lab tested?
The company reports small-batch third-party testing for chemicals, heavy metals, and contaminants, with mitragynine content standardized per can.
Are there kratom seltzer alternatives with kava?
That's our corner. GudTonics blends kava and kratom extract in one bottle with published alkaloid content, if you want the social lift and the mellow base note together.
Final Verdict
- Mitra-9 is the most drinkable pure-kratom option we've reviewed, and the printed 45 mg dose is exactly the transparency this category needs.
- Price is the honest weakness. Regulars will feel it.
- No kava means no blend option, which is either irrelevant or decisive depending on what you're after.
- The variety 4-pack is the correct first purchase if you're seltzer-curious.
If you try Mitra-9 and find yourself wishing the fruit came with a rounder, calmer base underneath, that's the exact itch our kava-kratom tonics scratch. Browse the GudTonics lineup, check the lab numbers on the label, and pick your flavor. Bubbles optional, transparency standard.
