Q1. What is cranberry extract and what is it used for in dietary supplements?

Cranberry extract is a standardized fruit ingredient from Vaccinium macrocarpon, used primarily for urinary tract health and antioxidant support. Its quality markers are the proanthocyanidins, or PACs, led by procyanidin A2, CAS 41743-41-3, molecular formula C30H24O12, molecular weight 576.5 g/mol; the general proanthocyanidin class carries CAS 4852-22-6, C30H26O13, 594.5 g/mol. Purecium supplies Cranberry Extract 25% (25:1 concentrate) and Cranberry Organic Powder as 25 kg drum B2B raw material.

Q2. What is the difference between Cranberry Extract 25% and Cranberry Organic Powder?

Cranberry Extract 25% is a concentrated water extract produced at a 25:1 fruit-to-extract ratio, delivering an elevated proanthocyanidin load in a small dose for high-potency capsules and tablets. Cranberry Organic Powder is a minimally processed whole-fruit powder from certified organic cranberries, retaining the full fruit matrix including fiber and natural sugars, and is suited to clean-label, organic and food-form applications. Buyers should choose by dosage form and label positioning and verify the PAC assay on the CoA.

Q3. Why are proanthocyanidins the key marker for cranberry?

Proanthocyanidins are the marker class most studied for cranberry's urinary tract health applications, and cranberry PACs are distinguished by their type-A linkages, which are characteristic of cranberry and related Vaccinium species and less abundant in other fruits. PAC content therefore serves both as a potency assay and as an identity signal for authentic cranberry. Procyanidin A2, CAS 41743-41-3, C30H24O12, 576.5 g/mol, is the reference compound for PAC standardization.

Q4. How does cranberry support urinary tract health?

Cranberry type-A proanthocyanidins are studied for their ability to interfere with the adhesion of uropathogenic bacteria to the urinary tract lining, supporting the body's natural urinary defense mechanisms. Published clinical studies suggest that regular intake of cranberry supports urinary tract wellness, particularly in women. Typical servings range from 200 mg to 500 mg of concentrated extract per day. Finished-product claims should follow the regulations of the destination market.

Q5. What does the 25:1 concentration ratio mean in practice?

The 25:1 ratio means that 25 parts of fresh cranberry fruit are processed to produce 1 part of extract, an industry-standard notation for concentrated fruit extracts. It indicates the concentration factor of the extract, not the PAC percentage; the actual PAC content is quantified separately by assay and reported on the Certificate of Analysis. Buyers should always compare PAC assays rather than ratios alone.

Q6. Is cranberry extract safe and is it covered by regulatory reviews?

Cranberry has a long history of use in food and dietary supplements, and the European Food Safety Authority has assessed cranberry for its role in reducing bacterial adhesion in the urinary tract. The NIH Office of Dietary Supplements also discusses cranberry in its botanical factsheets. As with any botanical, formulators should follow market-specific guidance on dosage and claim wording for the destination country.

Q7. What are the typical applications of cranberry extract in finished products?

Cranberry extract is used in urinary tract health supplements, women's wellness formulas, antioxidant blends and combination products with D-mannose, probiotics and vitamin C. Typical servings range from 200 mg to 500 mg of concentrated extract per day, or 500 mg to 1500 mg of whole-fruit powder. The extract suits capsules, tablets, chewables, stick-packs and powders.

Q8. Can cranberry extract be combined with other ingredients?

Yes. Common pairings are D-mannose and probiotics for comprehensive urinary tract support, vitamin C for antioxidant blends, and other fruit and botanical extracts in women's wellness formulas. Both grades blend well into capsules, tablets, chewables and drink mixes. Formulators should verify ingredient compatibility and note that the organic powder contributes natural sugars and fiber.

Q9. Is cranberry extract vegan?

Yes. Purecium's cranberry grades are derived entirely from Vaccinium macrocarpon fruit with food-grade water extraction or gentle drying, with no animal-derived materials, carriers or processing aids. Both carry clear vegan, non-GMO, allergen-free and gluten-free statements and are suitable for vegan and vegetarian formulations.

Q10. How is cranberry authenticity verified and adulteration prevented?

Identity is confirmed by macroscopic examination of the fruit source together with analytical fingerprinting against authenticated Vaccinium macrocarpon reference material, per current USP-NF and European Pharmacopoeia methodology. The type-A PAC profile is an additional authenticity signal, since it distinguishes cranberry from other fruits with different proanthocyanidin structures. Each batch's CoA reports identity and PAC content.

Q11. What is the difference between PACs and total polyphenols in cranberry?

Proanthocyanidins are a specific subclass of condensed tannins and the marker most associated with cranberry's urinary tract applications, while total polyphenols is the broader measure of all phenolic compounds in the fruit, including flavonols and anthocyanins. The two assays answer different questions: PAC content confirms the cranberry-specific marker load, while total polyphenols measures overall antioxidant phenolic content. Both can be reported on the CoA.

Q12. What quality documentation should I request when sourcing cranberry extract?

Request a current specification sheet, a batch-specific Certificate of Analysis showing identification, PAC content, residual solvent, heavy metals, pesticide residues and microbial results, an SDS, allergen and gluten statements, and non-GMO declarations. For the organic grade, also request the organic certificate and traceability documentation, plus Kosher and Halal certificates, ISO 9001 and FSSC 22000 certificates, and stability data for registration.

Q13. What is the MOQ and lead time for cranberry extract from Purecium?

The minimum order quantity is 25 kg. Both grades are packed in 25 kg drums with food-grade aluminum-foil inner bags, and samples and technical documentation are available before you commit. Standard production lead time is typically 7 to 15 working days after order confirmation, with faster dispatch for stocked items. For North American customers, Purecium holds inventory at its US warehouse, enabling pickup or delivery within approximately two days.

Q14. How should cranberry extract be stored, and what is the shelf life?

Store in tightly sealed original containers in a cool, dry place below 25 degrees Celsius, protected from moisture and light. Both grades are stable under these conditions, and shelf life is generally 24 to 36 months from the date of manufacture depending on grade. Each shipment's CoA states the production date and expiry date for inventory planning.

Cranberry Extract Overview

Cranberry extract is a standardized fruit ingredient obtained from Vaccinium macrocarpon, the American cranberry most widely used in dietary supplements for urinary tract health and antioxidant support. Its recognized quality markers are the proanthocyanidins, or PACs, a class of condensed tannins led by procyanidin A2, CAS 41743-41-3, molecular formula C30H24O12 and molecular weight 576.5 g/mol; the general proanthocyanidin class carries CAS 4852-22-6, molecular formula C30H26O13 and molecular weight 594.5 g/mol. PAC content is the assay point by which cranberry extract quality is standardized.

For the dietary supplement industry, cranberry is used in urinary tract wellness, antioxidant and women's health formulas. Purecium supplies two grades, Cranberry Extract 25%, a 25:1 water-extracted concentrate, and Cranberry Organic Powder, a whole-fruit organic powder, sold exclusively as B2B raw materials for distributors, contract manufacturers, private-label producers and finished supplement brands.

Source & Ingredient Identity

Purecium Cranberry Extract is produced from the fruit of Vaccinium macrocarpon harvested at full maturity from verified cultivation, extracted with food-grade water under controlled temperature, concentrated and dried to a fine powder, while the organic grade is processed from certified organic whole cranberries into a fruit powder with minimal processing. Botanical identity is confirmed by macroscopic examination together with analytical fingerprinting against authenticated reference material.

The two grades are distinguished by their form and PAC delivery: Cranberry Extract 25% is a 25:1 concentrated water extract with elevated PAC concentration, while Cranberry Organic Powder retains the full fruit matrix including fiber and natural sugars. For B2B buyers, the critical purchasing checks are the PAC assay and the concentration or processing statement on the Certificate of Analysis, the organic certification for the organic grade, and the heavy metal and pesticide profile of the crop.

Key Characteristics of Cranberry Extract

1. PAC-standardized urinary tract support. The defining characteristic of cranberry extract is its proanthocyanidin content, the marker class studied for urinary tract health. PACs are quantified on every batch, and the type-A proanthocyanidin linkage of cranberry is the characteristic that distinguishes cranberry PACs from those of other fruits.

2. Studied antioxidant activity. Cranberry is rich in polyphenolic antioxidants including PACs, flavonols and anthocyanins; published research indicates that cranberry polyphenols support antioxidant defense and vascular health, alongside the widely studied urinary tract applications. Finished-product claims should follow the regulations of the destination market.

3. Two grades for two formulation strategies. Cranberry Extract 25% delivers a concentrated PAC load for high-potency capsules and tablets, while Cranberry Organic Powder suits clean-label, organic and food-form applications. Both grades are non-GMO, allergen-free, gluten-free and vegan, and both blend cleanly into capsules, tablets, chewables, stick-packs and powders.

Cranberry Extract Manufacturing

The manufacturing process begins with selection and quality testing of Vaccinium macrocarpon fruit, followed by extraction with food-grade water under controlled temperature to preserve the proanthocyanidin and polyphenol profile, clarification, concentration, and spray or vacuum drying to a fine powder. The organic powder grade is produced from certified organic whole fruit by gentle drying and milling to retain the fruit matrix. Every stage is process-controlled with in-process checks on temperature, concentration and drying parameters.

Each finished lot is tested for proanthocyanidin content, identification, residual solvent, heavy metals, pesticide residues and microbial limits, all reported on the batch Certificate of Analysis. Each lot is traceable from fruit lot to finished drum, and analytical methods follow the current USP-NF and European Pharmacopoeia approaches for fruit extracts where applicable.

Applications of Cranberry Extract

Urinary tract health is the primary application of cranberry extract. Mechanistically, cranberry type-A proanthocyanidins are studied for their ability to support urinary tract defense by interfering with bacterial adhesion to the urinary tract lining, and published clinical studies suggest support for urinary tract wellness with regular use. Typical supplement servings range from 200 mg to 500 mg of concentrated extract per day, or 500 mg to 1500 mg of whole-fruit powder.

Antioxidant and women's health formulas form the second cluster. Cranberry is used in antioxidant blends alongside vitamin C, in women's wellness and urinary support products, and in combination with probiotics and D-mannose for comprehensive urinary tract formulas. Both grades suit capsules, tablets, chewables, stick-packs and powders.

Formulators should note that cranberry has a characteristic tart, fruity taste that is well accepted in chewables and drink mixes, and that the 25% concentrate is the higher-potency choice for small dosage forms while the organic powder supports clean-label positioning.

Manufacturing & Quality Control

Purecium Cranberry Extract is produced in facilities operating under ISO 9001 and FSSC 22000 certified quality systems, with Kosher and Halal certification available. Analytical methods follow the current USP-NF and European Pharmacopoeia approaches for fruit extracts, with proanthocyanidin quantification on every released batch.

Each commercial lot is fully traceable from fruit lot to finished drum, and the batch is released only when identity, assay, residual solvent, heavy metals, pesticide residues and microbial results are all within specification. Alongside the CoA, Purecium provides the specification sheet, SDS, allergen and gluten statements, non-GMO declarations, organic certificates for the organic grade and stability data on request.

Cranberry Extract for B2B Supplement Manufacturing

Purecium supplies Cranberry Extract exclusively as a B2B raw material for distributors, contract manufacturers, private-label producers and finished supplement brands. The minimum order quantity is 25 kg; both grades are packed in 25 kg drums with food-grade aluminum-foil inner bags, and samples and full documentation are available before commitment.
