Pterostilbene (PTE, CAS 537-42-8) is a naturally occurring polyphenolic stilbene structurally related to resveratrol, primarily found in blueberries and Pterocarpus species. Featuring two methoxy groups in its molecular structure, pterostilbene offers enhanced lipophilicity and improved stability compared with resveratrol, making it a preferred functional antioxidant ingredient in dietary supplements and advanced nutritional formulations.
Natural Field supplies high-purity wholesale pterostilbene powder characterized by consistent particle size, low moisture content, and reliable batch-to-batch quality. Our pterostilbene bulk powder ensures excellent compatibility with capsules, tablets, powders, and compound nutraceutical blends. Bulk supply, OEM/ODM services, and complete technical documentation are available to support global customers.

Antioxidant Formulations: Pterostilbene is used to support antioxidant systems by helping protect cells from oxidative stress caused by environmental and metabolic factors.
Inflammation-Balanced Nutrition Products: It is frequently included in formulations designed to support a balanced inflammatory response and overall cellular comfort.
Brain Health Formulas: Thanks to its ability to cross the blood–brain barrier, pterostilbene is commonly used in products formulated to support cognitive performance and neurological function.
Healthy Aging & Longevity Blends: Pterostilbene is a popular ingredient in longevity-oriented supplements, often combined with resveratrol, NAD-related ingredients, or other polyphenols to support cellular vitality over time.
Overall, pterostilbene is valued as a stable, bioavailable polyphenol with broad formulation versatility and is actively studied for its role in modern wellness and nutritional science.
High Purity & Verified Quality: Purity ≥ 99%, verified by HPLC test with low heavy metals.
Enhanced Stability Profile: Structural methylation improves resistance to oxidation and degradation during formulation and storage.
Antioxidant Support Ingredient: Commonly used in formulations designed to support cellular protection and oxidative balance.
High Formulation Compatibility: Suitable for capsules, tablets, powders, and multi-ingredient blends.
Scalable Bulk Supply: Factory-direct production with flexible specifications and global supply capability.
For seeking a comprehensive antioxidant ingredient profile, consider pairing with bulk pure resveratrol powder from Natural Field. While pterostilbene offers enhanced stability and lipophilicity, resveratrol is a well-established polyphenolic compound widely used in nutritional and cosmetic formulations. Together, they can be incorporated into synergistic antioxidant and wellness blends.
