Pterostilbene Powder – Natural Antioxidant and Longevity Support
Pterostilbene Powder, also referred to as trans-Pterostilbene, is a high-purity antioxidant compound structurally related to resveratrol and naturally found in blueberries and certain plants. The active component pterostilbene is valued for its strong antioxidant activity and significantly higher bioavailability compared with many similar polyphenols. Because of these characteristics, Pterostilbene Powder has become an important ingredient in formulations designed for healthy aging, cellular protection, cognitive support, and metabolic health.
In recent years, the global nutraceutical market has shown increasing demand for high-purity Pterostilbene Powder, especially in longevity supplements and premium antioxidant formulas. As the market expands, buyers are placing greater emphasis on purity consistency, stability, and formulation compatibility rather than simply sourcing the ingredient itself.
Our production focuses on stable, high-purity Pterostilbene Powder suitable for bulk supply and finished product development. Compared with many standard materials on the market, we pay particular attention to crystal stability and purity control, which helps maintain consistent performance in capsules, tablets, and powder blends. At the same time, our manufacturing and OEM capabilities allow partners to customize specifications, particle size, and packaging formats according to their formulation or brand requirements. This flexibility makes it easier for supplement brands and product developers to integrate Pterostilbene into new anti-aging and antioxidant product lines with confidence.
Why Our Pterostilbene Powder?
1. High Purity trans-Pterostilbene (≥99% HPLC)
Consistent purity ensures accurate dosing and reliable performance in supplement formulations.
2. Naturally Higher Stability than Resveratrol
The dimethylated structure provides better oxidation resistance, helping maintain potency during processing and storage.
3. Optimized for Manufacturing
Controlled particle size improves blending uniformity and supports capsule and tablet production.
4. 20 Years Manufacturing Experience + OEM Flexibility
Nearly two decades of production expertise with customizable specifications and packaging for efficient product development.

Key Production Considerations
1. Control of trans-Pterostilbene purity is critical because the trans form provides the desired biological activity.
2. Crystallization and impurity control are important to maintain purity above 98–99%.
3. Protection from excessive moisture and light helps maintain long-term stability of the polyphenol compound.
4. Particle size control improves mixing uniformity and capsule filling performance.
Key Formulation Considerations
1. Pterostilbene is lipophilic, so it works well in capsules, softgels, and lipid-based delivery systems.
2. When used in powder blends, proper homogeneous mixing is required because the recommended dosage is relatively small.
3. It is often used in synergistic longevity formulations with NAD+ boosters or polyphenols.
4. Avoid prolonged exposure to high temperature and humidity during processing to preserve stability.
Common Applications of Pterostilbene Powder
1. Longevity & Healthy Aging Supplements

2. Cognitive Health Products
Added to brain health supplements targeting memory support, focus, and neuroprotection.
3. Cardiovascular Health Formulas
Used in formulations designed to support healthy cholesterol levels and vascular health.
4. Metabolic & Blood Sugar Support
Included in metabolic health supplements to support glucose metabolism and overall metabolic balance.
5. Premium Antioxidant Blends

5. Most dietary supplement products on the market use 50–150 mg per serving.
FAQs
1. What is the difference between Pterostilbene and Resveratrol?
Pterostilbene has a similar molecular structure but higher bioavailability and better stability due to its dimethylated structure, which allows better absorption and longer activity in the body.
2. Is Pterostilbene natural or synthetic?
It can be produced through plant extraction or synthesis. High-purity commercial products are often produced through controlled synthesis to ensure ≥98–99% purity and stable supply.
3. Is Pterostilbene safe for dietary supplements?
Pterostilbene is commonly used in nutraceutical products worldwide and is generally formulated within the 50–250 mg daily intake range in finished supplements.
4. What ingredients work well with Pterostilbene?
It is commonly paired with NMN, NAD+ precursors, Resveratrol, Quercetin, or CoQ10 in longevity and antioxidant formulations.
