The 2 oz KavaShot is the rare grab-and-go kava that prints its dose: 500 mg of kavalactones per shot, from the brand's own CO2 extract, at about $6 a shot by the case. We weigh the number, the taste, the price per milligram, and who should actually buy a twelve-pack versus a single.

Verdict first: the Root of Happiness KavaShot is the best disclosed-dose kava shot you can buy by the case on Amazon. Each 2 oz bottle states 500 mg of kavalactones, it is made from the brand's own Polynesian Gold 70% solventless CO2 extract in an FDA-registered cGMP facility, and the 12-count box lands at $72.00 at our August 2026 check, about $6.00 a shot or $1.20 per 100 mg of kavalactones. That is concentrate pricing, not powder pricing, but it is the cheapest disclosed kavalactones in a sealed, no-prep format we have found.
The number is the whole point. Most shots and cans in this category tell you an extract weight or nothing at all; Root of Happiness tells you the potency, which means you can dose with intent, compare it to a traditional shell, and know when to stop. We verified the Amazon listing live and in stock today, and we pulled every spec below from the brand's own product pages rather than inventing a lab panel.
The honest caveats are in here too: the Amazon listing carries a middling star rating with a small review count, 500 mg in one swallow is a full session's worth for most drinkers and too much for a first-timer, and the tropical mango flavor is sweetened to mask an extract that is, underneath, intensely bitter. Usual ground rules: kava is for adults, it can cause drowsiness, do not drive after taking it, and if you take medications or are pregnant, talk to your doctor. None of this is medical advice.
The short version
- 500 mg of kavalactones per 2 oz shot, disclosed by the brand; that is roughly two to three traditional shells in one swallow.
- $72.00 for the 12-count on Amazon at our check, about $6.00 a shot and $1.20 per 100 mg, the best disclosed value among sealed, no-prep kava formats.
- Built on Root of Happiness's in-house Polynesian Gold 70% CO2 extract, made in its own FDA-registered cGMP facility with COAs via the American Kava Association.
- Not a first-timer's dose: a full shot is a whole session. Newer drinkers should sip half and wait 30 minutes.
- Amazon reviews are thin and mixed at our check; the brand's paperwork, not the star count, is the reason to trust the label.

01 · The Disclosed-Dose Shot
Our PickRoot of Happiness KavaShot (2 oz, 12-count)
The only case-packed kava shot on Amazon that prints a real kavalactone number: 500 mg per 2 oz.
Lab report: Discloses 500 mg of kavalactones per 2 oz shot, built from the brand's own Polynesian Gold 70% solventless CO2 extract. Produced in Root of Happiness's FDA-registered cGMP facility with HPLC and microbial testing; certificates of analysis issued via the American Kava Association. We would still like a downloadable per-lot COA on the Amazon listing itself.
The KavaShot exists to solve one problem: kava without the kitchen. Root of Happiness's 2 oz shot is a concentrate built from the brand's own Polynesian Gold extract, a solventless 70% CO2 kava extract produced in-house, flavored tropical mango and bottled as a single serving. The label states 500 mg of kavalactones per shot. For context, our dosage guide puts a typical full session at roughly 150 to 250 mg split across two to four shells, so one bottle is a complete evening's worth of kava, taken in about four seconds.
On value, the arithmetic is simple because the brand gives us a denominator. $72.00 for twelve shots is $6.00 a shot, and 500 mg per shot makes that $1.20 per 100 mg of kavalactones. K-Tropix discloses the same 500 mg at a higher per-shot price; TRU KAVA is a gentler root-juice shot in a different weight class. Against traditional powder the shot is still expensive per milligram, as every concentrate is, but you are paying for zero prep, a sealed dose, and a number you can plan around.
Taste is the honest weak spot. Kava extract is ferociously bitter and the mango sweetener is doing heavy lifting; most drinkers describe it as 'medicinal tropical,' best taken cold and fast, and followed by a chaser. The texture is syrupy. None of that is unusual for a shot, but if flavor is your first criterion, a can will suit you better.

- 12-count verified live and in stock, August 2026
What we like
- Disclosed 500 mg kavalactones per shot, the number most shots never print
- Cheapest disclosed kavalactones in a sealed, no-prep format at ~$1.20 per 100 mg
- Made by a kava-concentrate specialist in its own cGMP facility
- Case of 12 in stock on Amazon, so it ships fast and earns Prime
Worth noting
- Bitter extract under a sweet mango mask; not a sipping drink
- A whole shot is a full session, too much for a first-timer
- Thin, mixed Amazon reviews at our check
Who should buy it: Buy the 12-count if you already drink kava, want a portable dose that states its potency, and are tired of strainer bags on weeknights. It is the right shot for travel, for the pre-dinner wind-down, and for anyone who dislikes guessing. Buy a single first if you have never had kava or if 500 mg sounds like a lot to you, because it is.
What we don't like: The flavor is sweet-over-bitter and the mouthfeel is syrupy. The Amazon listing's review count is small and its rating is middling, which makes it a harder first purchase than it deserves to be. A full shot is more than a first-timer should take in one go. And we want a per-lot COA posted on the listing, not just issued on request.
Bottom line: This is the shot we reach for when the question is 'how much kava is actually in this.' 500 mg per bottle is a stated, standardized dose from a twelve-year kava-concentrate specialist, and at about $6.00 a shot by the case it is the cheapest disclosed kavalactones in any sealed format we track. The flavor is a sweet tropical mango over an unmistakably bitter extract, the Amazon review count is small, and a full shot is a lot for a newcomer. Buy the case if you already know you like kava and want a number you can trust.
02 · Same Extract, Smaller Dose
Root of Happiness Liposomal Kava Capsules (30 ct)
The same Polynesian Gold extract in a 250 mg capsule, for drinkers who want half the shot's dose and none of the taste.
Lab report: Discloses 250 mg of kavalactones per capsule from the same in-house 70% CO2 extract; encapsulated in the brand's own FDA-registered cGMP facility with COAs via the American Kava Association.
Same extract, half the dose, zero taste. The Liposomal Kava Capsules use the same Polynesian Gold CO2 extract as the shot, encapsulated at 250 mg of kavalactones each. One capsule is a sensible single serving; two is the shot. At $28.00 for thirty at our check, that is roughly $0.93 per capsule or about $0.37 per 100 mg, which makes it cheaper per milligram than the shot because you are not paying for a bottle and a flavor system.
The trade is onset. A liquid concentrate on an emptier stomach arrives noticeably faster than a capsule that has to dissolve; for a pre-dinner wind-down the shot wins, for a quiet, flavorless evening dose the capsule does. We rank the full capsule shelf in our capsule guide, where this bottle holds the top slot.
- Kavalactones per capsule
- 250 mg (disclosed)
- Count / price
- 30 capsules, $28.00 on Amazon at our check (~$0.93 each)
- Source
- Same Polynesian Gold 70% CO2 extract as the shot; liposomal delivery
- Testing
- FDA-registered cGMP facility; COAs via American Kava Association
What we like
- 250 mg disclosed per capsule, a more forgiving dose than the shot
- No flavor, no syrup, no chaser
- Cheaper per milligram than the shot
Worth noting
- Slower onset than a liquid
- Very few Amazon reviews at our check
Who should buy it: Buy the capsules if you want the shot's standardized extract in a smaller, tasteless, cheaper-per-milligram serving, or if you want to titrate from 250 mg up rather than starting at 500.
What we don't like: Slower onset than the liquid. The Amazon listing is newer and has very few reviews at our check, so you are trusting the brand's paperwork rather than crowd feedback.
Bottom line: If the shot's 500 mg and mango syrup are the two things holding you back, this is the answer from the same kitchen: 250 mg per capsule, no flavor at all, about $0.93 a capsule. Two capsules equal one shot. It is our top pick in the capsule roundup for exactly this reason.

Questions, answered
How much kava is in a Root of Happiness KavaShot?
The brand discloses 500 mg of kavalactones per 2 oz shot, made from its Polynesian Gold 70% solventless CO2 extract. That is roughly two to three traditional shells of medium-strength brew in one serving, and a full session for most drinkers.
Is the Root of Happiness kava shot strong?
Yes, by any sealed-format standard. 500 mg in one swallow is above the community's typical 150 to 250 mg session total. Experienced drinkers will find it a complete evening's dose; first-timers should take half and wait 30 minutes before deciding on the rest.
How much does the KavaShot cost per shot?
The 12-count box was $72.00 on Amazon at our August 2026 check, about $6.00 a shot. Single shots sell for around $6.50 to $7 direct. Prices move, so confirm on the listing before you order.
What does the Root of Happiness kava shot taste like?
Sweet tropical mango over a strongly bitter extract, with a syrupy texture. It is designed to be taken cold and fast, not sipped. Most drinkers keep a chaser handy.
Is the KavaShot lab tested?
Root of Happiness produces the extract and the shot in its own FDA-registered cGMP facility with HPLC and microbial testing, and issues certificates of analysis via the American Kava Association. We would like to see a per-lot COA posted directly on the Amazon listing.
Kava shot or kava capsules, which should I buy?
The shot for speed and a full 500 mg dose with no prep; the brand's 250 mg liposomal capsules for a smaller, flavorless, cheaper-per-milligram serving with slower onset. Two capsules equal one shot, from the same extract.
