Our solution exhibits 80% oral bioavailability compared to 20% for normal resveratrol and addresses the major industrial obstacle of fast metabolic breakdown and inadequate cellular absorption. Our product is produced in our 20,000 square metre facility with SGS-standardized labs and more than 150 professional experts, with standards up to 98% purity. Our facility is cGMP, ISO22000, HALAL and KOSHER certified. We have a complete quality assurance system with third party testing and traceability mechanisms that ensure that every batch is within international requirements for heavy metals, pesticide residues and microbiological safety.

Pterostilbene Supplier

Pterostilbene powder is a dimethylated analogue of resveratrol obtained from natural sources like the heartwood of Pterocarpus marsupium and blueberries. This trans-stilbene polyphenol has increased lipophilicity due to the methoxy substitution, allowing for better penetration into cellular membranes and crossing of the blood-brain barrier. It yields persistent therapeutic plasma concentrations, with an increased half-life of about 105 minutes compared resveratrol’s 14 minutes. Our extract undergoes sophisticated purification procedures to provide a stable white powder for cognitive health, metabolic support and anti-aging compositions that need high-performance bioactive compounds.

Pterostilbene Extract Advantages

Increased Bioavailability: Our extract offers over four times more cellular concentration than resveratrol by optimised methoxy substitution, guaranteeing optimal therapeutic effect at lesser doses.

Extended Half-Life: Your formulations offer extended bioactivity with metabolic stability >105 minutes, decreasing dose frequency and enhancing consumer compliance in supplement programs.

Improved Lipophilicity: Being lipid-soluble allows for effective passage of the blood-brain barrier, making it especially useful for nootropic and cognitive health applications where water-soluble chemicals do not work.

Photostability Guarantee: Pharmaceutical-grade manufacturing and light-protective Packaging safeguard against trans-to-cis isomerisation, preserving the integrity of the active substance during the 24-month shelf life.

Difference Between Natural Pterostilbene And Synthetic Pterostilbene

Shaanxi hongda has two products,please contact us to get your request:duke@hongdaherb.com

Application of Pterostilbene Extract

Cognitive & Neuroprotective Supplements: A next-generation nootropic for enhancing memory and relieving anxiety via hippocampal plasticity modulation and acetylcholinesterase inhibition, going beyond typical brain health ingredients.

Metabolic Health Products: PPAR-alpha agonist for cardiovascular and blood sugar control formulations and triglyceride reduction and lipid profile support in complicated oxidative stress situations.

Premium anti-aging skincare: It blocks tyrosinase and reduces inflammatory cytokines in dermocosmetic serums and creams, penetrating the dermis more deeply than water-soluble antioxidants for better photoaging protection.

Sports Nutrition Used in recovery formulations to minimise oxidative stress caused by exercise and to boost mitochondrial function which assists competitive athletes by enhancing cellular energy metabolism.                  

Manufacturing process

Step 1 - Raw Material Selection: Qualified Pterocarpus marsupium heartwood is subjected to rigorous botanical identification and pesticide residue screening. Result: Extraction is performed using only pharmaceutical grade ingredients.

Step 2 - Precision Extraction: Plant material undergoes controlled solvent extraction using food-grade ethanol under optimized temperature and pressure parameters. Maximum stilbene yield, minimum co-extraction of impurities.

Step 3. Chromatographic purification. Crude extract is fed to preparative HPLC columns for the separation and purification of the compounds. Result: Purities higher than 98% with total elimination of structural analogues.

Step 4 - Crystallisation & Drying: Crystallised under control and then dried in vacuum in 100,000-level purification workshops. Best particle size distribution and stable white powder.

Step 5 - Quality Testing: Each batch is tested for HPLC purity, heavy metal screening, microbiological testing and pesticide residue verification. Full conformity with international standards prior to release.

Step 6 - Light-Protective Packaging The finished product is packaged in double-layer PE bags in opaque fibre drums under nitrogen environment. Result: Protection against light deterioration and oxidation during storage and transit.

Report of Third Test

Bioavailability Confirmation Independent pharmacokinetic tests have shown that our product has 80% oral bioavailability with maximum plasma concentration attained in 2 hours after treatment, which also demonstrates better absorption compared to non-methoxylated stilbenoids.

Purity Tested:Minimum 98% purity and no trans-to-cis isomerisation when kept to specs as per SGS and Eurofins third-party HPLC testing.

Safety Profile Toxicological investigations support the GRAS designation and no adverse effects have been identified at the recommended inclusion levels in food, beverage and dietary supplement categories.

Peterostilbene Vs Resveratrol

FAQ

Q: Why should I take your product rather than resveratrol?

A: Our product has 80% bioavailability compared to resveratrol's 20%. Plus we have a 7 times longer half-life. So you have larger cellular concentrations at smaller dosages, which is more cost-efficient to formulate.

Q: How do you avoid deterioration in storage?

A: We store in double layer PE bags within light proof fibre drums. Recommended storage below 25°C in a dry environment to avoid trans-to-cis isomerisation and retain 98% purity during the 24 month shelf life.

Q: Is your extract natural or synthetic?

A: We offer both botanical-sourced extract from Pterocarpus marsupium for natural labeling requirements and high-purity synthetic options exceeding 99% for standardized pharmaceutical applications, with C14 carbon dating available for verification.

Q: Can it be used in aqueous formulations? 

A: Due to lipophilic properties, we recommend nano-emulsion technology or cyclodextrin complexation for liquid applications. Our technical team provides solubility enhancement consultation for beverage and liquid supplement development.

Q: What third-party testing do you provide?

A: Every batch includes SGS or Eurofins testing for pesticide residues, heavy metals, microbiological parameters, and nutritional labeling, with complete documentation supporting your regulatory submissions.
