Contact UsSilybin (a bio-active flavonolignan constituent derived from Silybum marianum / Milk Thistle) represents one of the most clinically researched natural hepatoprotective and metabolic regulation compounds in contemporary phytotherapy. However, conventional uncomplexed Silybin extracts suffer from a significant bio-pharmacokinetic limitation: extremely low oral bioavailability (typically under 2% to 5%). This poor systemic absorption stems from Silybin's high lipophilicity coupled with poor aqueous solubility in gastrointestinal fluids, extensive hepatic first-pass glucuronidation, and low mucosal intestinal permeability.
The Phytosome Breakthrough: Silybin Phospholipids represent a molecular complex formed by reacting pure Silybin with phosphatidylcholine (derived from non-GMO soy or sunflower lecithin) at a precise 1:1 or 1:2 molar ratio. Unlike simple physical mixtures, Silybin Phospholipids form a true amphipathic complex where the hydrophilic flavonolignan head forms hydrogen bonds with the polar choline head group of the phosphatidylcholine molecule, enveloping the active ingredient within a lipophilic lipid shell.
When ingested, standard flavonolignans aggregate in aqueous intestinal fluids, failing to cross the unstirred water layer bordering the microvilli of intestinal enterocytes. By contrast, RAAG Biotech's Silybin Phospholipid complex acts as a bio-mimetic carrier. The outer phospholipid envelope seamlessly integrates into the lipid membrane of intestinal epithelial cells, facilitating passive transcellular diffusion and lymphatic transport. This bypasses initial hepatic degradation and dramatically elevates maximum plasma concentrations ($C_{max}$) and overall area under the curve ($AUC_{0-\infty}$).

Singapore has established itself as Southeast Asia's primary hub for biomedical R&D, high-value nutraceutical manufacturing, and premium healthcare brand headquarters. Positioned within Tuas Biomedical Park and Singapore Science Park, formulators require raw materials that satisfy stringent quality standards while targeting the pressing health trends of Asia's urban population.
Addressing the growing prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD/MAFLD) and metabolic syndrome among urban Singaporeans through targeted hepatoprotective supplements.
Incorporation into premium lifestyle recovery shots and direct-to-consumer stick-packs formulated for fast-paced professionals in Singapore's financial district.
Application in topical skincare serum and inner-beauty nutricosmetics targeting solar-induced oxidative stress, lipid peroxidation, and skin barrier maintenance in tropical climates.

Utilizing high-compatibility phospholipid complexes to create ultra-stable oily suspensions for self-emulsifying drug delivery systems (SEDDS).
Procuring dietary supplement ingredients for the Singaporean market requires strict compliance with local regulatory frameworks established by the Health Sciences Authority (HSA) under the Health Products Act. Unlike basic commodity raw materials, Silybin Phospholipids supplied to Singapore must satisfy precise chemical safety and physical parameters:
Singapore HSA mandates rigorous screening for heavy metals (Lead ≤ 10 ppm, Arsenic ≤ 5 ppm, Mercury ≤ 0.5 ppm, Cadmium ≤ 0.3 ppm), residual solvents (compliant with ICH Q3C Guidelines), and total microbial counts. RAAG Biotech provides batch-specific Certificate of Analysis (COA) packages verified by third-party ISO 17025 accredited laboratories (SGS, Eurofins) prior to dispatch.
Singapore’s year-round tropical rainforest climate falls under ICH Stability Zone IVb (30°C ± 2°C / 75% RH ± 5% RH). Standard phospholipid complex powders are susceptible to moisture absorption, agglomeration, and lipid peroxidation if improperly processed. RAAG Biotech utilizes micro-encapsulation spray drying and vacuum barrier foil packaging to guarantee a 24-month stable shelf life without physical degradation or loss of marker potency.
As Singapore acts as a premier trade bridge into neighboring ASEAN economies (Malaysia, Indonesia), botanical ingredients must be Halal-certified. RAAG Biotech’s Silybin Phospholipids and Quercetin raw materials are Halal and Kosher certified, ensuring seamless regulatory acceptance across regional Islamic food authority frameworks.
Established in 2014, RAAG Biotech Co., Ltd. is a high-tech botanical extract manufacturer operating under cGMP, ISO9001, ISO22000 (HACCP), HALAL, and KOSHER audited management systems. We specialize in converting standardized raw herbs into high-purity monomers, CO2 supercritical oleoresins, and bio-enhanced phospholipid complexes.
Equipped with modern supercritical fluid extraction, multi-stage column chromatography, and low-temperature vacuum drying systems to protect heat-sensitive active markers.
Our dedicated analytical center features high-performance liquid chromatography (HPLC-DAD), gas chromatography (GC-MS), and atomic absorption spectroscopy (AAS) for real-time batch release verification.
Contracted GAP planting bases ensure full traceability from botanical origin, harvest date, and pesticide control records directly to the final sealed export drum.
Detailed technical and commercial answers tailored for Singaporean formulators, QA managers, and supply chain executives.
Our standardized Silybin Phospholipid complex contains 29.0% to 37.0% Silybin (calculated by HPLC as the sum of Silybin A and Silybin B) with a total Phosphatidylcholine content of ≥ 55.0%, ensuring strict stoichiometric consistency.
Every shipment is accompanied by a comprehensive regulatory packet: Batch Certificate of Analysis (COA), MSDS, Technical Data Sheet (TDS), Flow Chart, Non-GMO Statement, Allergen Declaration, Residual Solvent Report, and Heavy Metal/Microbial test panels.
Yes. In addition to our standard soy-derived phosphatidylcholine complex, we manufacture a 100% non-GMO Sunflower Phosphatidylcholine Silybin complex specifically for allergen-free and clean-label supplement positioning.
