Product Specifications

Active Ingredient

100% Noble Kava Root Powder, a blend of noble kava varieties sourced from multiple islands in the Republic of Vanuatu. 100% lateral root composition. 9%+ kavalactone content verified by independent third-party HPLC lab testing under the FELR standard. No stems, stumps, leaves, or fillers.

Chemotype

Stone's reference chemotype is 426531, placing kavain first and dihydrokavain second in the kavalactone sequence. Because Stone is a blend of different noble kava varieties rather than a single cultivar, the precise chemotype can vary slightly from batch to batch as the blend composition shifts. What remains constant across every batch is that kavain and dihydrokavain are the dominant kavalactones, and this is what gives Stone its certified noble status. A noble kava must have a chemotype that begins with either 4-2 or 2-4, and Stone consistently meets that classification.

Root Composition

100% lateral root. This is the highest kavalactone-density part of the kava plant, tested and verified under the FELR (Forney Enterprise Lateral Root) standard as part of FDA cGMP compliance. Using only lateral roots across the entire batch is what drives the 9%+ figure and separates Stone from every other variety in our range in terms of raw potency.

Grind Type

Medium-fine aggregated powder with particle sizes between 40-200 microns. Finer than a traditional medium grind, it prepares efficiently and extracts well with either the kneading or blender method.

Other Ingredients

None. 100% pure noble kava root powder, confirmed by microscopy lab results.

Quality and Lab Testing

Every batch of Stone undergoes independent third-party lab testing at Flora Research Laboratories and Kappa Labs as part of a cGMP-compliant manufacturing process. Testing follows the FELR (Forney Enterprise Lateral Root) standard and includes microscopy, HTPLC, and HPLC on each imported batch using the square root of n+1 sampling method, covering identity, purity, composition, and kavalactone content. All lab reports are made publicly available. Manufactured, packaged, and labelled in an FDA-registered, cGMP-compliant facility under secure conditions to prevent adulteration.

What Does 9%+ Kavalactone Content Actually Mean?

Kavalactone percentage is the most direct measure of kava potency. Most of the kavas in our range sit between 5-7.87%+ per gram of root powder. Stone tests at 9%+ consistently, which means you need meaningfully less root powder per session to achieve the same effect level you'd get from a standard-strength kava at full dose.

The practical implication is important: if you approach Stone with the same dose you use for Kelai, Palarasul, or even Wow, you will significantly overshoot. The starting dose for Stone is lower than what you're used to, and the effects arrive faster and run deeper. Respecting that from the first session is what separates a great experience from an uncomfortable one.

Understanding Stone's Noble Certification

The six kavalactones that define a kava's chemotype are, in order of their numbering: desmethoxyyangonin (1), dihydrokavain (2), yangonin (3), kavain (4), dihydromethysticin (5), and methysticin (6). A kava's chemotype is written as the descending order of these compounds by concentration. To be certified noble, a cultivar must lead with either kavain (4) or dihydrokavain (2), meaning a chemotype that starts with 4-2 or 2-4.

Stone's reference chemotype 426531 leads with kavain (4), followed by dihydrokavain (2), which places it firmly in the noble category. Because Stone is a blend of noble varieties rather than a single cultivar, the exact sequence can shift slightly batch to batch as the blend composition changes, but the critical first two positions, kavain and dihydrokavain as the dominant compounds, remain consistent across all batches. This is what the independent lab testing at Flora Research Laboratories and Kappa Labs verifies on every imported batch.

What Does Stone Feel Like?

Stone's kavain-dominant chemotype means the heady effects arrive first and arrive fast. Within 15-20 minutes on an empty stomach, mental relaxation is already well underway. The heady phase is pronounced and clear-headed, and the body component follows with a weight and depth that experienced drinkers will recognise as the top end of what noble kava produces. The session holds for a full 2-4 hours and the taper is gradual, but the peak is considerably more substantial than anything else in the range. Our article on what kava feels like describes the general kava experience well, though Stone sits at the most intense end of everything described there.

This is not a kava you drink while doing other things. Stone is a dedicated session kava. You prepare it, you sit down somewhere comfortable, and you give the experience the attention it earns.

How to Prepare Stone

The full preparation guide covering every method is at How to Make Kava (Without Making a Mess). The methods are the same as for any medium-fine kava, but the dose is different and that difference matters significantly with Stone.

Because of the 9%+ kavalactone content, start with 20-25g (roughly 3-4 tablespoons) per 500ml of water rather than the standard 30-35g ratio used for the rest of the range. Prepare on a completely empty stomach, at least 3-4 hours after your last meal. For the kneading method, room temperature or slightly warm water (40-60°C) works best. For the blender method, cold or room temperature water only, since blending generates heat and warmer water degrades the kavalactones.

Pace yourself across 1-2 shells spaced 20-25 minutes apart and give the first shell a full 30 minutes before deciding whether to add more. At this potency level, patience between shells is more important than it is with any other kava in the range.

Stay Hydrated

Kava is a diuretic, much like coffee, and Stone's higher potency makes this worth paying extra attention to. Drink a glass of water between shells throughout your session and keep water on hand for the hours after. This helps you avoid dry skin and the mild headache that some people experience the next morning after a strong session.

Yield Guide by Pack Size

• 30g: a single first session at the conservative starting dose of 20-25g, with a small amount left to calibrate on a second session if needed. The right size for a first try.
• 56.5g: 2-3 sessions at conservative dosing, enough to properly assess Stone and find your personal level.
• 125g: approximately 5-6 sessions, a good supply for an experienced drinker who has confirmed this is their variety.
• 250g: approximately 10-12 sessions at standard dosing, the best value per gram for regular drinkers.

A Note on Tolerance and First Sessions

Stone is the one kava in our range where the first session advice is worth reading carefully rather than skimming. At 9%+, the effects are fast, pronounced, and deeper than what most people have experienced with other kavas. Keep the first session at home on a quiet evening with no obligations, start at 20-25g, and give it the full 30-minute assessment window before adding more. There is no benefit to pushing the dose on a first session with a high-potency kava, and a conservative first experience gives you the information you need to calibrate from a position of knowledge rather than discomfort.

Reverse tolerance applies here too. Some experienced kava drinkers find that the effects deepen noticeably over the first three to five sessions with a new variety as the body adjusts. Even if the first session at 20-25g feels manageable, avoid jumping to higher doses in the second session.

How Stone Fits Into the Kava Kenya Range

Stone vs Wow:

Wow is a Borogu-based noble blend at 7.87%+ with a 70/30 basal-to-lateral composition that produces a rich, layered effect profile with a built-in balanced-to-heavy arc. Stone runs at 9%+ from 100% lateral root across a kavain-dominant noble blend, making it more direct in character and higher in raw potency. Wow is the step you take before Stone, and understanding the difference between the two gives you a clear picture of where Stone actually sits.

Stone vs Loa Waka:

Loa Waka is our Fijian benchmark kava at 6%+ from pure lateral root, producing a strong, balanced, full-spectrum session. Stone runs at 9%+ using the same lateral root standard across a blend of Vanuatu noble varieties, which means roughly 50% more kavalactone density per gram. Think of Loa Waka as the step you take before Stone rather than a comparable alternative.

Stone vs Palarasul and Kelai:

Palarasul and Kelai are euphoric, approachable kavas at 5-6%+ that are excellent for building a kava practice and understanding your dose. Stone is the direction you go after you've done that work and want to explore the upper end of what noble kava produces. These are not competing alternatives; they're different points on the same path.

Stone vs Borongoru:

Borongoru is a heavy, sedating kava purpose-built for deep evening relaxation and sleep support, with a single-cultivar chemotype that goes physical fast and reliably. Stone's kavain-dominant blend also produces strong effects, but the multi-variety lateral root profile makes the specific direction of those effects broader than the targeted sedation of Borongoru. For dedicated sleep support, Borongoru is still the cleaner choice. For maximum potency across both mental and physical dimensions, Stone is where you go.

Safety Information

For Experienced Kava Drinkers Only:

Stone is not recommended for first-time kava drinkers or people who are still finding their dose with lighter varieties. The 9%+ kavalactone content produces effects that can be overwhelming for those without a baseline familiarity with how their body responds to kava. Start with Kelai, Palarasul, or Loa Waka and work up to Stone once you have that reference point.

Consult a Healthcare Provider Before Use If:

You take medications processed by the liver, have a history of liver conditions, are pregnant or breastfeeding, take sedatives, anti-anxiety medications, antidepressants, or sleep aids, or have surgery scheduled within the next two weeks.

Do Not Combine With:

Alcohol, sedative medications, anti-anxiety medication, sleep aids, muscle relaxants, or antidepressants without medical guidance. Kava and alcohol together significantly amplify sedation, and this is especially important with a high-potency kava like Stone.

Driving Warning:

Do not drive or operate machinery after consuming Stone. Effects run for a minimum of 4-6 hours and at 9%+ kavalactone content the impairment can be more pronounced than with standard-strength kavas. Plan your transport well before the session.

Potential Side Effects:

Mild nausea from consuming on a full stomach, dizziness at high doses, dry and scaly skin with extended daily use, and significant temporary motor impairment are the most commonly reported effects. At Stone's potency level, overshooting your dose produces more pronounced discomfort than it would with lighter kavas, which is why starting conservatively matters.

When to Stop and Seek Medical Attention:

Yellowing of the skin or eyes, unusual fatigue or weakness, dark urine, pale stools, or persistent nausea and stomach pain all require immediate medical review and permanent discontinuation of kava.

Frequently Asked Questions

Is kava legal in Kenya?

Yes. Kava is a botanical plant product with no classification as a controlled substance under Kenyan law. Kava Kenya imports and sells kava legally, and every batch is independently lab-tested for purity and kavalactone content before it reaches customers.

Why does the chemotype change between batches?

Stone is a blend of different noble kava varieties rather than a single cultivar, so the precise chemotype sequence can shift slightly as the blend composition changes from one harvest to the next. What stays constant is that kavain and dihydrokavain are always the dominant compounds, which is what the 4-2 opening of the reference chemotype 426531 confirms and what the independent lab testing verifies on every batch. The noble classification holds regardless of the minor variation between batches.

What is FELR and why does it matter?

FELR stands for Forney Enterprise Lateral Root. It's the specific testing standard used to verify that Stone's root composition is 100% lateral root under FDA cGMP compliance guidelines. Lateral roots carry the highest kavalactone concentration of any root part, and FELR verification confirms that what's in the bag matches what's on the label. It's the standard that makes the 9%+ figure credible rather than just claimed.

How is Stone lab-tested and how do I access the results?

Each imported batch is tested at Flora Research Laboratories and Kappa Labs using the square root of n+1 sampling method, which is the industry standard for batch testing. Tests include microscopy, HTPLC, and HPLC to verify identity, purity, composition, and kavalactone content. All lab reports are made publicly available, so if you want to review the specific batch results for what you're buying, you can access them directly.

Why is the starting dose lower than other kavas in the range?

At 9%+, Stone delivers significantly more kavalactones per gram than the 5-7.87%+ kavas that most of our customers drink regularly. Applying the standard 30-35g dose you'd use for Kelai or Wow to a first Stone session puts you well above the effect level you're calibrated to. Starting at 20-25g per 500ml gives you a controlled introduction and lets you calibrate from there rather than from a place of having gone too far.

Can I blend Stone with a lighter kava to manage the intensity?

Yes, and this is a technique experienced kava drinkers use regularly. Blending Stone with a smaller amount of Kelai, Palarasul, or Wow in the same preparation batch lets you take advantage of Stone's potency while the lighter variety's kavalactone profile softens the overall character of the session. A 50/50 blend by weight at a total of 25-30g per 500ml is a reasonable starting point for that approach.
