Frequently Asked Questions
Which kosher certifications do you hold or can secure?
We hold or coordinate certification under OU (Orthodox Union, global gold standard), OK Kosher / Kof-K (fast certification track), Star-K (technical specialist for heat-sensitive process), CRC (Chicago Rabbinical Council, regional and global), KSA (Kosher Supervision of America, West Coast US), and KLBD (London Beth Din, UK and EU retail). The agency we recommend depends on your target retail channel; OU is the right default for mainstream US grocery and most export markets, OK is faster to first production, KLBD is the cleanest path into UK and EU retail.
Pareve vs dairy, which should my supplement be?
Default to pareve (neither meat nor dairy) unless your formulation genuinely requires dairy ingredients (whey protein concentrate, milk-derived calcium, casein). Pareve carries the maximum market flexibility, satisfies dairy-free and vegan positioning at the same time, and avoids the OU-D dairy symbol which restricts when the consumer can use the product alongside meat-based meals. All our gummy, capsule, powder, sachet, and liquid-drop formats run pareve by default.
How long does OU certification take from formula submission?
A new facility-product OU certification typically runs 6-10 weeks from formula submission, covering ingredient audit, supplier vendor-list cross-check, facility inspection by the OU rabbinic coordinator, equipment kashering where required, first supervised production, and certificate issuance. OK Kosher commonly runs 3-5 weeks for the same scope, which is why we recommend OK for time-to-market launches. Subsequent reorders on an approved formulation run on standard 30-45 day production timelines without re-certification.
Can you certify a botanical with potential insect contamination?
Yes, on validated supplier inspection. The insect-prone botanicals (alfalfa, broccoli, strawberry, parsley, spinach, dill, and similar) ship only from suppliers running a documented inspection protocol that the cert agency recognises; we audit the supplier's inspection certificate at intake and quarantine any lot arriving without one. For raw whole-leaf material where inspection is impractical, we substitute a microbially-inspected powdered extract or recommend a non-insect-flagged alternative at the audit stage.
What is the kosher status of bovine collagen and gelatin?
Bovine collagen and bovine gelatin require kosher slaughter (shechita) on the source animal under rabbinic supervision, which is the structural reason most kosher collagen on the market is marine rather than bovine; the kosher-shechita bovine supply is small and carries a substantial surcharge over conventional bovine collagen. Marine collagen from kosher-certified fish (scale-and-fin species) is the cleanest path and ships under a plain pareve symbol or OU-Fish depending on agency convention. Porcine gelatin is non-kosher in all cases and is never used in our kosher production.
How do you prevent cross-contamination on shared equipment?
Equipment that previously ran non-kosher production goes through a documented kashering protocol under mashgiach supervision: 24-hour idle period to neutralise any absorbed taste (eino ben yomo status), boiling-water hagalah for stainless contact surfaces, libun thermal for ovens and drying tunnels. The mashgiach signs the kashering log before the first kosher run. Pareve runs are segregated from any dairy-equipment runs in the production schedule with documented changeover. The kashering log is part of the agency's annual audit file.
What are the renewal and audit cycle costs?
Cert agencies invoice on an annual facility-plus-product fee structure that varies by SKU count, ingredient complexity, and supervision intensity (mashgiach yotzei v'nichnas periodic inspection versus mashgiach temidi continuous on-site). Cholov yisroel and high-sensitivity SKUs carry a surcharge for the continuous-supervision requirement. We invoice the agency fee through at cost on production runs and include the standard supervision overhead in the per-unit quote; cholov yisroel and pas yisroel surcharges are flagged separately on the formal quote.
Can OU and OK certifications coexist on the same SKU?
Yes, dual certification is a common configuration when channel strategy requires both marks (OU for mainstream US grocery acceptance and OK for specific regional or export channels). The two agencies run independent audits on the same production but accept each other's vendor approvals on ingredient lots, which removes most of the duplication. Dual-certification SKUs carry both symbols on the label; the production run itself does not double in cost, only the annual agency fees stack.

Kosher Manufacturing: Pareve, Dairy, Multi-Agency Coverage
The US kosher food and supplement market is $24B+ at the retail level with +9% annual category growth, and 21% of kosher buyers are non-Jewish (driven by clean-label perception, allergen control, and the OU mark functioning as a third-party quality signal). Over 12M Americans actively seek the kosher symbol on shelf. The Orthodox Union (OU) symbol alone appears on more than one million SKUs globally, which makes it the single most recognised third-party food and supplement mark in North American grocery. For a brand owner, kosher certification is two things at once: a religious-law compliance instrument for the observant Jewish consumer, and a quality-perception instrument for the general health-conscious shopper who never asks the rabbi. Our manufacturing program treats it as both.
We hold or coordinate certification under the six major kashrus agencies, scoped to your retail channel. The Orthodox Union (OU) is the global gold standard and the symbol US natural-grocery, mainstream retail, and most export markets check first; it carries the longest lead time (typically 6-10 weeks for a new facility-product approval) and the heaviest documentation burden. OK Kosher (Kof-K) offers a faster certification track with comparable retail acceptance, often the right choice for time-to-market. Star-K is the technical specialist for heat-sensitive processes and unusual ingredient chemistry. CRC (Chicago Rabbinical Council) covers regional Jewish retail and international export. KSA (Kosher Supervision of America) is the West Coast US standard for Pacific natural-grocery distribution. KLBD (London Beth Din) is the OU equivalent for UK and EU retail. We can run a single SKU under two coexisting certifications (OU + OK is the common pair) when channel strategy requires it.
Kosher status is a three-way classification: pareve (neither meat nor dairy), dairy, or meat, and the status determines what dishes and timeframes the consumer can use the product alongside. We default every formulation to pareve, which carries the maximum market flexibility (a pareve supplement can be consumed with any kosher meal) and simultaneously satisfies dairy-free, vegan, and most allergen-conscious positioning. The cert agency assigns the symbol accordingly: plain OU is pareve, OU-D is dairy, OU-Fish is fish, OU-DE indicates dairy equipment without dairy ingredients. Cholov yisroel (extra-strict dairy supervision requiring continuous Jewish oversight from milking through processing) is available on dairy-containing SKUs for the Orthodox premium segment at a documented surcharge; cholov stam is the standard dairy classification. Pas yisroel (extra-strict bread supervision) and yashan (extra-strict grain harvest-timing rules) apply on grain-derived ingredients where the brief specifies.
Technical compliance runs on a dual stack: cGMP per 21 CFR Part 111 for the FDA side and the kashrus agency's published manufacturing standard for the kosher side. Equipment that has previously run non-kosher production is kashered under rabbinic supervision (boiling-water hagalah for stainless, libun for ovens, with a 24-hour idle period before the kashering itself); the mashgiach (rabbinic supervisor) signs the kashering log. Botanical extracts with insect-contamination history (alfalfa, broccoli, strawberry, parsley, spinach, dill) ship only from suppliers running validated insect-inspection protocols, which we audit at intake. Vegan HPMC capsule shells are the default because bovine and porcine gelatin both raise halacha complications, and HPMC sidesteps them entirely. Vegetable glycerin replaces animal glycerin in soft-gel and liquid formulations as standard. Alcohol-extracted flavors are classified against the halachic 1/6 nullification threshold (bitul b'shishim); above-threshold ethanol carriers require kosher-for-Passover certification on the extract source. Bovine collagen and gelatin require kosher slaughter (shechita) on the source animal, which is the structural reason most kosher collagen on the market is marine rather than bovine.
Our Manufacturing Process
From initial concept to finished product, every step is managed under one roof with dedicated quality oversight and transparent communication.
Kashrut Ingredient Audit + Agency Selection
Every ingredient on your formulation is mapped against the agency's master kosher database (OU LSI, OK Halacha Yomis, Star-K database) for current certification status and any seasonal restrictions. Non-compliant items (porcine gelatin, non-kosher glycerin, insect-derived carmine, certain enzyme sources) are flagged with kosher-approved alternatives at the audit stage, not after production. We recommend the cert agency based on your retail channel (OU for mainstream US grocery, OK for time-to-market, Star-K for heat-sensitive process, CRC for regional Jewish retail, KSA for Pacific natural-grocery, KLBD for UK/EU).
Mashgiach Coordination + Equipment Kashering
We schedule the mashgiach (rabbinic supervisor) for facility inspection, ingredient sign-off, and production-day attendance. For a previously non-kosher production line we run a documented kashering protocol: 24-hour idle, boiling-water hagalah for stainless contact surfaces (or libun thermal for ovens and tunnels), mashgiach signature on the kashering log. Pareve runs are segregated from any dairy-equipment runs in the production schedule with a documented changeover. Mashgiach temidi (continuous on-site supervision) is available for cholov yisroel and high-sensitivity SKUs; mashgiach yotzei v'nichnas (periodic spot inspection) is the standard.
Supervised Production under Dual Compliance
Manufacturing runs under cGMP per 21 CFR Part 111 with parallel kashrut compliance: ingredient lot numbers cross-checked against the agency's approved-vendor list at intake, batch records co-signed by QA and the mashgiach at critical control points, segregation maintained against any concurrent non-kosher production. Cleaning logs, kashering logs, and batch documentation feed the agency's annual audit. Insect-prone botanicals run through their supplier's inspection certificate at intake; if a certificate is missing the lot is quarantined until cleared.
Certification Mark Release + Annual Audit Cycle
Finished cartons and labels carry the agency's certification mark (OU, OK, Star-K, etc.) with the correct status indicator (plain pareve symbol, -D for dairy, -DE for dairy equipment, -Fish for fish). Each lot ships with a kosher COA referencing the agency, certification number, mashgiach signature, and ingredient-lot traceability back to the approved supplier roster. The agency renews certification annually on a facility-plus-product basis (most agencies bundle the two); audit windows are scheduled in advance and we maintain the documentation file the inspector reviews.

Key Benefits for Your Brand
Every aspect of our kosher supplements manufacturing is designed to accelerate your time-to-market while maintaining uncompromising quality standards.
Six Major Cert Agencies on One Production Floor
OU (Orthodox Union, global gold standard, dominant US recognition), OK Kosher / Kof-K (fast certification track), Star-K (technical specialist), CRC (Chicago Rabbinical Council), KSA (Kosher Supervision of America, West Coast US), KLBD (London Beth Din, UK + EU). We coordinate the agency that matches your channel rather than forcing a single in-house option.
Pareve Default, Cholov Yisroel on Request
Every formulation runs pareve (neither meat nor dairy) by default for maximum market flexibility and dairy-free / vegan crossover appeal. Cholov yisroel (extra-strict dairy supervision) is available on dairy-containing SKUs for the Orthodox premium segment with documented surcharge. Pas yisroel and yashan are supported on grain-derived ingredients where the brief specifies.
Dual Compliance Stack (cGMP + Kashrut)
Manufacturing runs cGMP per 21 CFR Part 111 in parallel with the kashrus agency's published manufacturing standard. Batch records carry both QA and mashgiach signatures at critical control points; the audit file satisfies FDA inspectors and the agency's annual review on the same documentation.
Botanical Insect Inspection Built In
Insect-prone botanicals (alfalfa, broccoli, strawberry, parsley, spinach, dill) ship only from suppliers running validated inspection protocols, which we audit at intake. Lots arriving without a current inspection certificate are quarantined until cleared, which removes a category of kashrut risk most contract manufacturers leave to the brand owner to discover at audit.
HPMC Capsule + Vegetable Glycerin Defaults
Vegan HPMC capsule shells sidestep the bovine and porcine gelatin halacha entirely; vegetable glycerin replaces animal glycerin in soft-gel and liquid formats as standard. The structural choice is the simplest route to a clean OU pareve symbol without ingredient substitution surprises late in development.
