Plant Extract Supply is proud to offer our premium-grade ISO factory supply pterostilbene CAS 537-42-8 pterostilbene powder, a highly sought-after active ingredient designed for the dietary supplement, functional food, and advanced nutraceutical industries. Characterized by its exceptional purity and superior bioavailability, this potent polyphenolic compound is engineered to meet the stringent formulation requirements of global manufacturers and brand developers.
What is Pterostilbene?
Pterostilbene is a naturally occurring polyphenol structural analog of resveratrol, predominantly found in botanical sources such as blueberries, grape skins, and select plant heartwoods. While historically categorized within the broader families of plant flavonoids and stilbenoids, Pterostilbene is distinguished by its unique dimethylether structure. This structural advantage gives it enhanced lipophilicity, meaning it is more readily absorbed by the body, features superior cellular membrane penetration, and exhibits a significantly longer half-life compared to standard resveratrol.
Our pterostilbene powder is standardized to a purity of ≥ 99%, ensuring a concentrated, highly stable, and reliable active ingredient for premium health and wellness formulations.
Core Health Functions & Industry Applications
Due to its robust biological activity, pterostilbene powder is a highly versatile raw material. Formulators and product developers utilize this ingredient to target specific health endpoints:
1. Powerful Antioxidant & Cellular Protection
Pterostilbene acts as a formidable scavenger of oxidative stress and free radicals. By helping neutralise cellular damage, it is a foundational ingredient in advanced anti-aging supplements, longevity protocols, and cellular health formulas.
2. Cognitive Health & Neuroprotection
Because of its optimized lipophilic structure, Pterostilbene efficiently crosses the blood-brain barrier. Emerging industry research highlights its potential to support neurological pathways, making it a highly valuable component in nootropics and brain-health dietary supplements designed to aid memory, focus, and overall cognitive function.
3. Cardiovascular Support
Pterostilbene is frequently formulated into cardiovascular-support blends. Its natural physiological properties are thought to promote healthy blood flow, support vascular integrity, and help maintain optimal endothelial function.
4. Anti-Inflammatory Properties
Chronic inflammation is a core target in modern nutraceuticals. Pterostilbene’s potent biological mechanisms help modulate inflammatory pathways, making it an excellent addition to joint health, recovery, and holistic wellness products.
