Sea-Buckthorn Extract for Nutraceutical & Supplement Brands

What Supplement Formulators Need from Sea-Buckthorn

Sea-Buckthorn is a multi-active botanical: the berry provides dense carotenoid, flavonoid, and vitamin C profiles, while the seed and pulp oils deliver a rare 1:1 omega-3 to omega-6 ratio alongside palmitoleic acid (omega-7). For nutraceutical brands, the sourcing decision turns on extract standardisation, verifiable assay methodology, physical form suitability for the dosage format, and regulatory positioning under EU law. TANDOR addresses each of these directly as a Romania-based EU sourcing intermediary with multi-origin supply relationships across Central Asia and Eastern Europe.

Extract Forms & Technical Specifications

Standardised Dry Berry Extract (Capsule & Tablet Grade)

The most commercially relevant form for supplement brands is a standardised dry Sea-Buckthorn berry extract, typically expressed as minimum 10–30% total flavonoids (calculated as isorhamnetin) or minimum 0.5–5% total carotenoids, with identity confirmed by HPLC.

Key specification parameters relevant to procurement:

• Marker compounds: Isorhamnetin, quercetin, and kaempferol glycosides (flavonoids); β-carotene, zeaxanthin, lycopene (carotenoids); ascorbic acid (vitamin C)
• Assay method: HPLC — the industry standard for quantifying individual marker compounds with specificity and reproducibility; UV-Vis is sometimes used for total carotenoids but HPLC is preferred for COA credibility with EU notified bodies
• Particle size: For direct capsule fill or blend, D90 ≤ 150 µm is typical; for granulated blends or tablet compression, D50 in the 100–250 µm range is standard. Particle size distribution should be confirmed per batch by laser diffraction (e.g. per ISO 13320)
• Loss on drying: ≤ 5% (consistent with Ph. Eur. general monograph guidance for dry plant extracts)
• Heavy metals: Compliant with Ph. Eur. 2.4.27 limits (lead, cadmium, mercury, arsenic)
• Microbiology: Total aerobic count, yeast & mould, absence of Salmonella spp. and E. coli — per Ph. Eur. 5.1.4 and EU food supplement GMP expectations
• Pesticide residues: Screened per Regulation (EC) No 396/2005 MRL schedules
• Solvent residues: Class 2/3 solvents per Ph. Eur. 5.4 (relevant for ethanolic or hydroethanolic extracts)

Sea-Buckthorn Seed & Pulp Oil

For softgel and oil-drop formats, cold-pressed seed oil and CO₂-extracted pulp oil are available. Seed oil is characterised by its balanced polyunsaturated fatty acid profile; pulp oil is distinguished by its high palmitoleic acid (omega-7) content and intense carotenoid load, confirmed by GC-FID for fatty acid profile and HPLC for carotenoids.

Whole Berry Powder (Freeze-Dried)

Whole fruit powder (freeze-dried, spray-dried) is used in clean-label and food supplement matrix products. No standardisation claim is made on whole powders, but HPLC-confirmed indicative values can be included in the COA for formulation reference.

Certificate of Analysis — What TANDOR Provides Per Batch

Every batch is accompanied by a batch-specific COA, not a generic product specification sheet. For nutraceutical buyers, this distinction is critical for traceability obligations under EU food law (Regulation (EC) No 178/2002) and for substantiating QC records during audits.

A TANDOR COA for Sea-Buckthorn extract includes:

• Botanical identity (macroscopic/microscopic and HPLC fingerprint)
• Standardisation assay result (HPLC, with method reference)
• Particle size distribution data
• Loss on drying, bulk density, and tapped density
• Heavy metal analysis results
• Microbiological test results
• Pesticide residue screening summary
• Country of origin and harvest/production year
• EU-Organic certificate number (where applicable)

EU-Organic Certification

EU-Organic Sea-Buckthorn is available under Regulation (EU) 2018/848, which replaced the former Regulation (EC) No 834/2007 from January 2022 and sets the current legal framework for organic production and labelling in the EU. Organic certification covers both the cultivation of the raw berry and, where relevant, the processing conditions for extraction.

For brands carrying the EU Organic logo on finished products, the entire supply chain — from farm to extract — must be covered by valid organic certificates issued by an EU-accredited control body. TANDOR supplies the relevant organic transaction certificates and can support chain-of-custody documentation for your own certification authority.

EFSA Health Claim Status

EU brands should note that Sea-Buckthorn has no authorised Article 13(1) or Article 14 health claim under Regulation (EC) No 1924/2006 as listed in the EU Register of authorised claims. Claims referencing specific nutrient contributions (e.g. vitamin C content supporting the immune system — authorised per Regulation (EU) No 432/2012) may be made if the finished product meets the relevant nutrient profile conditions and the vitamin C content is analytically confirmed. Structure/function claims for Sea-Buckthorn as a botanical per se remain under the on-hold status applicable to most botanical submissions to EFSA. Brands should take independent regulatory advice before making on-label claims.

Origin, MOQ & Supply Realities

TANDOR works with multi-origin supply — primarily Romania, Russia/Altai region, Mongolia, and China — giving buyers access to the best-fit origin for their quality, certification, and cost requirements.

• Romania: EU-grown, shorter supply chain, easier organic chain-of-custody, smaller crop volumes
• Altai / Mongolia: High-altitude wild and semi-cultivated; very high carotenoid density; requires robust pesticide and heavy-metal screening given agricultural context
• China (Ningxia, Qinghai): Large-volume standardised extract production capacity; suitable for high-volume supplement SKUs; full COA documentation available

Minimum order quantities for dry extracts typically start at 5–25 kg for sampling and 25–100 kg for commercial orders, depending on origin and standardisation level. Oil MOQs start at 10–50 kg. TANDOR can confirm specific MOQs per origin and specification at enquiry stage.

Lead times range from 2–6 weeks depending on stock availability and required testing scope.
