Pharma-Grade Saw Palmetto: Precision-Engineered for Prostate Health by SRBio
SRBio’s Saw Palmetto Extract is not just a botanical powder; it is a vertically integrated, pharma-grade ingredient solution. By controlling the supply chain from USA wild-harvesting to our China-based GMP-certified extraction facilities, we deliver a consistently potent, pure, and fully traceable liposterolic extract. Standardized to ≥25% fatty acids and verified for bioactivity, our extract is the definitive choice for evidence-based men’s health formulations.
Uncompromising Quality: SRBio’s Manufacturing Excellence
-
Vertically Integrated Purity & Potency
-
USA Sourced Berries: We partner directly with growers in Florida and Georgia to source mature, wild Serenoa repens berries, bypassing commodity traders and ensuring raw material authenticity.
-
Precision Active Standardization: We guarantee efficacy through strict control of key bioactive markers:
-
≥25% Total Fatty Acids (GC-Validated): A precise profile of lauric, oleic, myristic, and linoleic acids—the key lipophilic actives for 5-alpha-reductase inhibition.
-
≥0.3% Phytosterols (HPLC-Tested): Beta-sitosterol and other plant sterols quantified for synergistic support of prostate and urinary health.
-
-
Uncompromised Safety:
-
Heavy Metals: Lead (Pb) ≤0.2 ppm, Arsenic (As) ≤0.1 ppm (ICP-MS).
-
Solvent Residues: ≤5 ppm; fully compliant with USP <467> (GC-FID).
-
Pesticides: Meets stringent EU MRL requirements (EPA 8081B tested).
-
-
-
Advanced Cold CO₂ Extraction Technology
-
Patented Subcritical Process: Our in-house, proprietary subcritical CO₂ extraction operates at ≤35°C (Patent No. CN2023XXXXX). This low-temperature method preserves the full spectrum of heat-sensitive fatty acids, preventing degradation common in ethanol or hexane extraction.
-
45% Liposterolic Concentrate: The process yields a rich, standardized 45% liposterolic extract with superior bioactivity and stability.
-
Eco-Impact: Our closed-loop system achieves 98% solvent recovery, resulting in zero waste and a significantly lower carbon footprint (EcoVadis Gold-certified process).
-
-
Full Blockchain Traceability
-
From Berry to Batch: Every production batch is fully traceable. A simple QR code scan provides access to:
-
Harvest date and origin of the USA berries.
-
DNA barcoding authentication of Serenoa repens.
-
Complete batch-specific lab reports (COA) including fatty acid profile, heavy metals, and pesticide screens.
-
-
Scientific Evidence: Mechanism & Efficacy
-
Prostatic Health & BPH Management
-
5-Alpha-Reductase Inhibition: The fatty acid-rich liposterolic fraction is clinically shown to inhibit the enzyme 5-alpha-reductase, thereby reducing the conversion of testosterone to DHT (dihydrotestosterone) in prostate tissue.
-
Clinical Data: A 12-week human study (data on file) demonstrated significant improvement in International Prostate Symptom Scores (IPSS), including reduced nocturia and improved urinary flow rate.
-
-
Testosterone Metabolism Support
-
Hormonal Balance: By modulating DHT levels without directly affecting systemic testosterone, Saw Palmetto helps maintain a healthy hormonal environment for prostate and hair health.

Competitive Breakdown: SRBio vs. Market Alternatives
Key Deficiencies in Standard or Unverified Saw Palmetto Extracts:
-
Inconsistent Potency: Many extracts lack guaranteed fatty acid and phytosterol levels, leading to unpredictable clinical outcomes.
-
Solvent Residues: Extracts using hexane or high-temperature processing risk degradation of active compounds and residual solvent contamination.
-
Lack of Traceability: Opaque supply chains make it impossible to verify source, authenticity, or purity.
