Kava is one of Sun's anchor categories — and one of the harder ingredients to manufacture well.
Kava has moved from a regional South Pacific tradition into a national consumer category over the past several years. Kava bars are open in dozens of US cities. The shot and beverage segment is one of the fastest-growing alcohol-alternative niches. Capsule and powder formats have followed retail demand into Amazon, Whole Foods, and the practitioner channel. Brand founders see the trajectory — the social-occasion ritual, the GABAergic relaxation positioning, the cannabis- and alcohol-adjacent category framing — and want to launch.
But kava is genuinely harder to manufacture at production scale than most ingredients. The active compounds — kavalactones — sit in a narrow window of stability and degrade under the wrong pH, temperature, or co-formulator conditions. The raw material supply chain runs through smallholder agriculture in Fiji and Vanuatu where cultivar quality varies enormously farm-to-farm. Heavy metals screening is non-negotiable. And the category is one where a brand's reputation is built on what the third-party Certificate of Analysis actually documents — not on what the label hopes is in the bottle.
Sun Nutraceuticals has built the sourcing relationships, the standardized-extract program, and the format-agnostic production line that a serious kava brand needs to scale across multiple SKUs without changing manufacturers. Brands working on their second, third, or fifth kava product end up here for that reason.
Every format, one standardized input
The reason kava brands consolidate manufacturing at Sun is operational: one verified raw material lot can move into four different finished formats. Capsule fills, powder pouches, liquid shots, and gummies all draw from the same standardized CO₂-extracted kava — so a multi-SKU product launch ships from a single sourced, tested, and documented input rather than four parallel supply chains.
Kava capsules — two-piece fill
Kava capsules are produced in two-piece gelatin, HPMC, or pullulan shells in sizes 0 and 00. The 70% kavalactone oleoresin is the typical capsule input — it delivers maximum actives per gram, minimizing the per-serving capsule count. Standard configurations range from 30-count travel bottles up to 180-count retail jars. Capsules are typical for daytime relaxation and stress-support positionings where consumers want a discrete, scoop-free format.
Kava powders — stand-up pouches
Kava powder ships in stand-up pouches in 100g, 250g, and 500g fill weights. Powder formats accommodate traditional kava preparation rituals as well as modern functional-beverage mixing. Sun produces both standardized-extract powders (for verified-dose label claims) and traditional noble-cultivar root powders (for brands targeting the on-premise kava-bar aesthetic). Both formats include kavalactone content documentation on every batch.
Kava liquid shots — 1 to 4 oz bottles
Kava shots are Sun's specialty within the kava cluster. Shots run on a dedicated shot-filling line in 1, 1.5, 2, 2.5, 3, or 4 oz bottle formats — HDPE or PET, with full-wrap shrink-sleeve or pressure-sensitive labels. Shot formulations are engineered for ambient-temperature shelf stability so the kavalactone content your label claims is the content your customer actually consumes months later off the retail shelf. See Kava Shots Manufacturer for the full shot-specialty details.
Kava gummies — pectin or gelatin
Kava gummies are Sun's newest format within the kava cluster. The 50 mg/mL liquid concentrate is the input — it disperses uniformly through the gummy slurry for predictable batch-to-batch kavalactone distribution, eliminating the per-gummy potency variability that plagues commodity kava gummy production. Pectin (vegan-positioned) and gelatin shells are both available. Bottle counts range from 30-count to 90-count retail configurations.
Sun's standardized kava extracts
Manufacturing kava at consistent batch-to-batch potency is impossible without working from standardized extracts rather than commodity root powder. Standardization means a documented kavalactone percentage and a verified profile of the six kavalactones that define a noble kava chemotype. Sun maintains two standardized grades produced via supercritical CO₂ extraction — no chemical solvent residues — which can be used in either Sun's finished-product line or sold as B2B raw material to other formulators.
70% kavalactone oleoresin
A semi-solid CO₂-extracted oleoresin standardized to approximately 70% total kavalactones by weight. Ideal where maximum actives per gram and minimum excipient load matter — capsule fills, custom concentrates, and downstream conversion. Lot-specific COAs document the kavalactone profile and total content for every batch.
50 mg/mL liquid concentrate
A shelf-stable liquid concentrate standardized to 50 mg kavalactones per milliliter — engineered for liquid applications where dosing by volume is the simplest path to consistent label claims. The liquid concentrate is the primary input for kava shots, RTD beverages, syrups, and gummies. Sold by the liter with volume pricing tiers available.
Noble cultivar root powders
For brands building product around the traditional kava category — kava-bar private labels extending to retail, ritual-positioned powder SKUs, traditional noble cultivars from specified origin regions in Fiji and Vanuatu. Standardization on root powders is documented but inherently less precise than on CO₂-extracted concentrates; the trade is authenticity and category fit.

The kava manufacturing process from brief to finished goods
- Discovery call. We discuss your kava concept, target kavalactone dose per serving, format preferences (capsule, powder, shot, gummy, or a multi-SKU program), positioning (relaxation, sleep, social-occasion, alcohol-alternative), MOQ, and timeline. We quote within one business day — specific line-item costs, not a range that requires follow-up to interpret.
- Formulation or formula review. If you bring a complete formula, we review it for kavalactone stability, co-active compatibility, and target-dose feasibility before moving to component costing. If you're starting from a brief, our formulators develop the formula — selecting the appropriate extract grade, kavalactone dose, flavor system (for liquid and gummy formats), and complementary actives if applicable — and produce bench samples for approval.
- Sample approval. You receive production-representative samples. Review, verify, sign off. Once the formula specification is locked, no changes are made without a new sample approval cycle.
- Raw material sourcing. Kava extract is sourced through Sun's direct supplier network in Fiji and Vanuatu to your specified standardization. Capsule shells, pouches, bottles, gummy components, and labels are procured in parallel.
- Production. Blending, encapsulation, pouch filling, shot filling, or gummy production runs on the appropriate Sun line under full cGMP batch documentation. Blend uniformity and in-process weight or volume checks run throughout each production run.
- Third-party testing. Every batch goes to an independent accredited laboratory for kavalactone identity and content quantification, noble chemotype confirmation, microbial safety panels, heavy metals, and pesticide screening. The Certificate of Analysis is provided before shipment — not as an afterthought.
- Packaging, labeling, and case-packing. Finished units are labeled and case-packed to your retail or DTC configuration — FBA-ready pallets, display-ready retail cases, kava-bar wholesale cases, or individual shipper cartons. FNSKU labeling for Amazon programs is accommodated.
- Fulfillment. Finished goods can move from Sun's facility directly to your warehouse, to Amazon fulfillment centers, or to consumers and retailers through Sun's integrated fulfillment operation.
What buyers look for in a kava manufacturer
Most kava brands evaluating contract manufacturers are working through the same short list of questions. The category has enough downside risk — quality variability at origin, kavalactone instability in the wrong formulations, third-party COA scrutiny from retail buyers and platforms — that buyers tend to be more diligent than in commodity categories. The criteria that matter:
- Is the kava raw material standardized? Commodity kava root with no documented kavalactone content is not a production input for a brand that wants to make consistent label claims. Sun works from standardized CO₂-extracted grades (70% oleoresin and 50 mg/mL liquid) with lot-specific COAs documenting kavalactone content on every input lot.
- Is noble kava chemotype confirmed? Non-noble kava cultivars — tudei and others — carry a different kavalactone profile and a different traditional-use history. Retail buyers, marketplace platforms, and informed consumers increasingly look for noble-chemotype confirmation on COAs. Sun confirms noble chemotype on every batch.
- Is heavy metals testing standard? Kava is sourced from agricultural supply chains where soil and processing variability make per-batch heavy metals screening non-negotiable. Sun tests every batch.
- Can you produce more than one format? Kava brands frequently launch a multi-SKU line — a capsule for daytime, a shot for social-occasion, a gummy for retail impulse. A manufacturer who runs all four formats from the same standardized input is meaningfully simpler to work with than four separate co-packer relationships.
- What's the actual MOQ? "Low MOQ" is meaningless without a number. Sun's kava MOQ is 5,000 units across all formats.
Who contracts kava manufacturing with Sun
Our kava programs serve a range of brand types across the relaxation, social-occasion, and functional-supplement market:
- Kava bar brands extending their on-premise brand into retail SKUs — capsules and shots are the most common entry points
- Alcohol-alternative and functional-beverage brands adding a kava shot or gummy to a broader portfolio
- Wellness and adaptogen brands incorporating kava into relaxation, sleep-support, or stress-positioned multi-ingredient stacks
- Established kava brands consolidating production with a manufacturer that can run multiple formats from a single standardized input
- Practitioner-channel brands formulating kava capsules for clinical or sleep-support applications where dose precision matters
Compliance, testing, and label claims for kava
Every kava product manufactured at Sun is produced in an FDA-registered, cGMP-compliant facility under documented batch records. Third-party laboratory testing is integrated into the production protocol on every batch — not an optional upcharge. Standard verification covers kavalactone identity and content, confirmation of noble kava chemotype, microbial safety panels, heavy metals testing, and pesticide screening.
Kava supplements are produced and labeled under FDA's structure/function claim framework. We are not your regulatory affairs consultant — what your label claims and how you position your product is a decision you make with your own counsel. What Sun delivers is a verified product, documented testing on every batch, and the technical accountability of a manufacturer that produces what the Certificate of Analysis says is in the bottle.
Frequently asked questions
What kava formats does Sun manufacture?
Capsules, powders, liquid shots, and gummies. Capsules are produced in two-piece gelatin, HPMC, or pullulan shells. Powders ship in stand-up pouches. Liquid shots run on Sun's shot-specific filling line in 1–4 oz bottle formats. Gummies are produced as a finished crossover format dedicated to the kava cluster. The same standardized kava input is available across every format so a brand launching a multi-SKU line draws from a single verified raw material lot.
What is the minimum order quantity for kava manufacturing?
Our standard MOQ across kava formats is 5,000 units. The number is the same whether you're producing capsules, powder pouches, shots, or gummies. Specific MOQs for multi-SKU programs or rush production windows are quoted on the discovery call — typically within one business day of the initial brief.
How is Sun's kava extract produced, and what is the standardization?
Our kava raw material is supercritical CO₂-extracted — no residual chemical solvents. Two standardized grades are stocked: a 70% kavalactone oleoresin (semi-solid, ideal for capsule fills and concentrates) and a shelf-stable 50 mg/mL liquid concentrate (ideal for beverages, shots, and gummies). Both grades carry lot-specific COAs documenting kavalactone content. Brands that need a different standardization target for a custom formulation can specify it during the discovery process.
Do you confirm noble kava chemotype on every batch?
Yes. Noble kava chemotype confirmation is part of Sun's standard kava testing protocol. The verification covers the kavalactone profile — kavain, dihydrokavain, methysticin, dihydromethysticin, yangonin, and desmethoxyyangonin — and confirms the cultivar profile matches a noble kava designation rather than a tudei or other non-noble variety. This is the kava-category equivalent of label-claim validation: it tells you and your customers what is actually in the bottle.
Is heavy metals testing performed on kava batches?
Yes. Heavy metals testing is built into Sun's standard kava production protocol on every batch. Kava is one of the ingredient categories where heavy metals screening is most important — soil and processing variability across smallholder agricultural supply chains makes per-batch verification non-negotiable. Results are documented on the Certificate of Analysis provided with every production run.
What is the lead time for kava manufacturing?
Typical lead time is 6 to 8 weeks from final formula approval and component arrival to finished goods. Repeat orders on established formulas often move faster because raw material, components, and production procedures are pre-qualified. Add 2 to 4 weeks if Sun is developing your formulation from a brief rather than running an existing locked formula.
Can Sun produce a kava blend with other actives?
Yes. Kava is frequently formulated alongside complementary actives — L-theanine, GABA, magnesium, valerian, passionflower, and ashwagandha are the most common pairings on our line. Blend uniformity is verified before fill on every multi-ingredient kava production run. We develop blends from your brief or run your existing validated formula. Co-active compatibility is reviewed during the formulation phase, since kavalactone stability is sensitive to certain co-formulators and pH ranges.
Does Sun supply bulk kava extract as well as finished products?
Yes. Sun operates both a bulk extract supply line and a finished-product manufacturing line, and brands can use either or both. The bulk channel sells the 70% oleoresin and 50 mg/mL liquid concentrate directly to formulators and beverage brands by the kilogram or liter. The finished-product channel takes the same standardized extracts through to capsules, powders, shots, or gummies. See `/kava-extract-bulk` for the raw-material supply details.
