Trans-pterostilbene bulk powder is a highly purified antioxidant ingredient widely used in dietary supplements, anti-aging formulations, and functional foods. Also known as pterostilbene powder or dimethylresveratrol, the compound is a naturally occurring methylated stilbene that is more bioavailable than its structural cousin, resveratrol.
Its active ingredient, trans-pterostilbene, is known for its potent antioxidant, anti-inflammatory, and cognitive support properties. It helps support cellular health, maintain NAD+ levels, and promote healthy aging, making it a top choice for brain health, longevity, and immune function formulations. In today's market, demand for bulk trans-pterostilbene continues to grow, driven by the growing interest in longevity research and NAD+-boosting supplements.
Highly purified trans-pterostilbene powders feature ≥98% purity, HPLC testing, fine particle size distribution, and excellent solubility, ideal for capsule, sachet, and premix applications. Unlike generic options, a fermentation-based sourcing and low-temperature drying process helps maintain the compound's active structure and stability. Custom OEM/ODM services are available, enabling brands to incorporate this trans-pterostilbene powder into custom formulations — whether capsules, ready-to-use powders, or private label packaging. With comprehensive documentation support, batch traceability, and certifications such as ISO22000, Kosher, Halal, and Organic, global brands can obtain both raw material and finished product solutions.
The trans-pterostilbene powder is tested by third-party laboratories and in-house quality assurance teams to consistently deliver ≥98% active ingredient (HPLC) with no fillers, diluents, or peak overlap. Batch COA is provided with every shipment.
Unlike standard powders that are coarse-mesh or unevenly sized, the product is processed to a uniform D90≤100μm particle size, ensuring better dispersibility in capsule, granule, or premix formulations. This reduces clogging issues on encapsulation lines.
The trans-pterostilbene is produced by fermentation rather than solvent synthesis. This approach retains the trans isomer, the bioactive form with superior metabolic stability and bioavailability. Clinical studies show that trans-pterostilbene has an oral bioavailability of up to 80%, compared to approximately 20% for average resveratrol.
Operating in the plant extract and bioactive ingredient business since 2008, the technical team includes senior chemists and process engineers. Fermentation, purification, and drying lines are ISO22000 and FSSC22000 certified, allowing strict control from raw materials to final powder.
In addition to raw powders, finished dosage form development support is available for global brands, including:
One-stop OEM/ODM services cover label design, small batch testing, and global compliance documentation.
