The purchaser is NATURVITA, a premium wellness group headquartered in Madrid, Spain, with 22 years of experience in high-end dietary supplement operations across the Iberian Peninsula. Its products are sold in El Corte Inglés premium supermarkets, private neurology clinics in Madrid, and organic pharmacies in Lisbon, Portugal. Core product lines include premium brain health capsules, sublingual instant magnesium powder, and middle-aged and elderly sleep-support compound tablets. All products comply with EU EFSA Novel Food regulations, Spain’s AENOR food standards, USP Pharmacopoeia, and REACH compliance requirements, targeting high-net-worth middle-aged and elderly consumers, high-stress office workers, and neurological wellness populations. The client maintains a stable annual purchase volume of 12 tons of L-threonate magnesium.
Previously, the client sourced patented L-threonate magnesium from European and American manufacturers, but overseas raw material price hikes and extended delivery lead times prompted plans to develop Chinese raw material supply chains. The client independently contacted five leading domestic L-threonate magnesium manufacturers (Magtein Wuxi Brain Magnesium, Shandong Tangzheng, Shandong Fengtai, Hubei Tuoyuan, Hebei Hongtao) for quotations and samples. However, all manufacturers only promoted their own products without objective cross-brand parameter comparisons, leaving the client unable to distinguish differences between patented pharmaceutical-grade, refined food-grade, and national standard general-grade materials, nor confirm whether purity and powder parameters matched its automated capsule and compound powder production lines, halting brand selection work. The client entrusted HiSiaddi to neutrally sort all mainstream brands and screen matching product models.
1. One-Sided Brand Promotion from Manufacturers: Sales teams at all five manufacturers only highlighted their own product advantages without objectively explaining competitors’ strengths, weaknesses, and applicable scenarios, with no horizontal comparative data. For example, patent manufacturers only emphasized patent qualifications while avoiding discussions on cost-effective generic grades; mass production manufacturers only highlighted price advantages while omitting shortcomings in powder modification and EU filing support.
2. Complex Brand & Model Classification with Limited Domestic Industry Knowledge: Domestic L-threonate magnesium is divided into three major categories: patented pharmaceutical grade, refined food grade, and national standard general grade. Each brand further subdivides three specifications for capsule use, ultrafine instant powder, and bulk generic materials. The client lacked understanding of process differences corresponding to powder, purity, and moisture-proof indicators, making it impossible to match products to its dual capsule and powder production line requirements.
3. High Terminal Compliance Threshold: Spanish import requires Novel Food supporting documents, full-item English SGS test reports, and REACH-SDS. Compliance supporting capabilities vary widely across brands, and the client could not independently assess the difficulty of document preparation for customs clearance.
· Core Technology: Globally licensed Magtein patented raw material produced via enzymatic synthesis and multi-stage refining, exclusive domestic patent production, EU Novel Food approved material in the UK.
· Three Main Product Models:
1. M1 Patented Pharmaceutical Grade (Capsule-Specific): Purity 99.7%–99.9%, magnesium content 12.8±0.2%, regular 110-mesh crystals with pre-HPMC moisture-proof coating, compatible with fully automatic capsule filling.
2. M2 Ultrafine Patented Grade (Sublingual Powder): 650-mesh ultrafine grinding, instant full dissolution in cold water without residues.
3. M3 Generic Food Grade: National standard purity ≥99.0%, uncoated bare powder, cost-effective option.
· Advantages: Most comprehensive patent endorsements, FDA GRAS + EU Novel Food certifications, full supporting EU compliance documents, top-tier bioavailability in the industry.
· Disadvantages: Higher unit price, high minimum order quantity, high sample testing costs for small batches, unsuitable for cost-sensitive compound raw materials.
· Main Models: TZ-1 Refined Pharmaceutical Grade, TZ-2 National Standard Food Grade, TZ-3 Custom Ultrafine Ground Grade
· Advantages: Large-scale mass production capacity, complete in-house crystallization and grinding production lines, sufficient standard off-the-shelf inventory, moderate pricing, comprehensive domestic national standard testing reports.
· Disadvantages: No international patent qualifications, mostly bare unmodified raw materials; additional third-party testing required for EU English test reports, weak compound formulation stability performance.
· Models: FT80 Generic Food Grade, FT-U Ultrafine Grade
· Advantages: Flexible minimum order quantity (1kg sample available), fast small-batch delivery, meets national standard indicators with outstanding cost performance.
· Disadvantages: Maximum purity limited to 99.2%, loose control over free impurities, no pharmaceutical-grade internal control standards, incompatible with high-end export formulation formulas.
· Models: TY-A High-Purity Refined Grade, TY-B Basic Food Grade
· Advantages: Fine synthesis process enabling minor particle size adjustments for small-batch orders, strict internal control over heavy metals.
· Disadvantages: Limited mass production capacity leading to long delivery cycles for large orders; only domestic COAs available with no EU filing dossiers.
· Model: HT Generic Bulk Food Grade with no subdivided particle size specifications
· Advantages: Lowest price, stable mass bulk delivery, suitable for beverages and ordinary health food products.
· Disadvantages: Mixed coarse and fine powder without grading, no dedicated modification processes, extremely prone to moisture absorption and caking, incompatible with high-end capsule and sublingual powder production lines.
Combining the client’s dual high-end capsule and sublingual powder product lines, strict EU compliance requirements, GABA plant extract compound formulations, and ocean shipping moisture-proof core demands, Fengtai and Hongtao (low-end generic brands) were eliminated. Two mid-to-high-end brands and three executable models were finalized:
1. Model M1 Patented Modified Capsule-Specific Material (Main Procurement Item): Pre-coated with HPMC moisture-proof modification, 115-mesh particle size, bulk density of 0.53g/cm³, blockage-free filling performance, precisely controlled magnesium content of 12.79%, complete supporting EU Novel Food filing documents and full-item English SGS test reports, used as the primary raw material for the client’s premium brain health capsules.
1. Model TZ-2U Ultrafine Refined Powder Grade (Exclusive for Sublingual Instant Dissolving Products): 660-mesh low-temperature ultrafine powder with instant full dissolution in cold water. Tangzheng can cooperate with HiSiaddi for post-production external coating modification, offering better cost performance than equivalent patented-grade materials for the client’s sublingual powder production line.
2. Model TZ-1 Refined Food Grade (Cost-Effective Compound Auxiliary Material): 99.5% medium-high purity for the client’s affordable sleep-support compound tablet line to balance overall raw material procurement costs.
Selection Logic: Magtein supplies raw materials for high-margin flagship products, while Tangzheng supports instant powder and mass-market mid-tier products. The combination balances product quality and procurement costs, fully matching the client’s full product line layout.
1. HiSiaddi coordinated sample delivery of corresponding models from both manufacturers, unified third-party SGS testing per Spanish import standards, and simultaneously supported four implementation verification tests at the client’s facility: filling machine operation test, compound accelerated stability test, water solubility test, and constant temperature moisture storage test.
2. All physicochemical and compliance indicators of the three models passed inspection by the client’s Spanish R&D laboratory.
3. The initial annual order totaled 12 tons, split into 5 tons of Magtein M1 modified material, 4 tons of Tangzheng TZ-2U ultrafine powder material, and 3 tons of Tangzheng TZ-1 refined material. HiSiaddi coordinated a full set of English COAs, REACH-SDS documents, and Spanish customs clearance notarized documents, with two separate shipments from Shanghai Port to Barcelona Port achieving zero customs clearance delays and no moisture-induced raw material caking during storage.
4. Smooth raw material production enabled the client’s new L-threonate magnesium capsules and powder products to launch in premium Spanish channels. In the first quarter post-launch, new product sales rose by 29% year-on-year compared with previous-generation products.
The client finalized a fixed annual procurement framework of 12 tons with phased quarterly orders. When the client later iterated low-allergen children’s formulas, it again entrusted HiSiaddi to conduct secondary brand and model selection based on new product specifications, permanently discontinuing scattered small-batch sample inquiries and price comparisons.
Domestic raw material manufacturers are sales-oriented and generally only promote their own products without objectively disclosing competitors’ strengths and weaknesses. High-end overseas brands lack familiarity with domestic manufacturers’ processes, compliance qualifications, and model classification, making them prone to selecting mismatched raw materials that lead to production line scrapping or product delistings. As a neutral third party, HiSiaddi horizontally breaks down the advantages and disadvantages of all mainstream brands and accurately narrows down brand and model options based on three dimensions: destination country regulations, product dosage forms, and cost, resolving information asymmetry pain points and securing long-term repeat orders through objective brand selection services.
