Description
The dimethylated analog of Resveratrol, naturally present in blueberries and Indian Kino tree (Pterocarpus marsupium) heartwood. The compound has substantially improved bioavailability and metabolic stability versus Resveratrol, supporting premium positioning in anti-aging and longevity supplement applications.
Off-white to light yellow crystalline powder. Limited water solubility; freely soluble in alcohol and oils.
We supply food-grade Pterostilbene from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 98 percent Pterostilbene (the standard supplement grade), 99 percent Pterostilbene (premium pharmaceutical-equivalent grade), and the patent-positioned premium grade pTeroPure from ChromaDex. Bulk material is typically produced by synthesis from resveratrol or pinosylvin precursors rather than by direct plant extraction due to low natural concentrations.
Bulk and reduced-MOQ shipments. Batch-level COA covering Pterostilbene content (HPLC), related stilbene impurities, residual solvents, heavy metals, and microbiology.
Introduction
Pterostilbene was first isolated from Indian Kino tree (Pterocarpus marsupium) heartwood in the 1970s and was later identified as a natural component of blueberries at low concentrations. The compound rose to commercial prominence in the 2010s as a premium bioavailability-enhanced alternative to Resveratrol following human pharmacokinetic studies showing several-fold higher plasma concentrations and longer half-life versus Resveratrol at equivalent doses.
Industrial production proceeds by chemical synthesis from resveratrol or pinosylvin precursors via O-methylation, followed by purification and crystallization. Direct plant extraction is not economically viable due to low natural concentrations.
Recognized as a permitted food ingredient in the U.S. (Generally Recognized as Safe via independent self-affirmation at up to 50 mg per day), pending Novel Food review in the EU.
Clinical evidence supports cardiovascular markers (cholesterol, blood pressure) at appropriate doses, with additional preclinical evidence for cognitive support and cellular senescence markers. The compound is the principal premium alternative to Resveratrol in longevity-positioned supplement applications.
Strategic positioning targets the premium anti-aging and longevity supplement segment specifically, frequently formulated alongside NAD+ precursors (NR, NMN), Resveratrol, and other senescence-management actives.
Where it is used
- Anti-aging and longevity dietary supplements: premium positioning versus standard Resveratrol (the dominant commercial application)
- Cellular-health and senescence-management supplement formulations
- Cardiovascular-support premium supplement formulations
- NAD+ and NMN combination supplement formulations
- Cognitive-support and brain-health premium supplements
- Cosmetic skincare: premium anti-aging serums and antioxidant skincare
- Sports nutrition: recovery and antioxidant premium positioning
- Pharmaceutical research applications
