What is Pterostilbene powder and how is it different from Resveratrol?

Pterostilbene is a natural stilbenoid compound found naturally in blueberries, grapes, and Pterocarpus marsupium heartwood. It shares a similar chemical structure with resveratrol, but features two key performance differences:

• Superior bioavailability: Two unique methoxy groups on its molecular structure make it more lipophilic, leading to far higher oral absorption rates and a much longer half-life (105 minutes, compared to only 14 minutes for resveratrol).
• Higher metabolic stability: It resists the rapid glucuronidation breakdown process that occurs in the liver.
  
  Both compounds are strong antioxidants, but pterostilbene is widely recognized as the "next-generation resveratrol" due to its more potent efficacy that remains effective even at lower dosage levels.

Is Pterostilbene powder approved for use in dietary supplements in the EU, USA, and China?

• USA: Permitted for use as a dietary ingredient under the DSHEA regulatory framework. GRAS self-affirmation is available for the ingredient, with no specified maximum concentration limit.
• EU: Classified as a Novel Food ingredient, it received formal approval under Regulation (EU) 2017/2470 for use in food supplements, with a maximum recommended daily intake of 150mg for adult consumers (excluding pregnant or lactating women).
• China: It is not currently approved as a new food ingredient or food additive. Pterostilbene does not appear in the official "Catalogue of Resources for Health Food" nor the "New Food Ingredients" list, so it cannot be used in ordinary foods or domestic dietary supplements sold within mainland China.
  
  We advise all commercial operators to confirm and comply with local regional regulations before launching any products containing this ingredient.

What are the main functions of Pterostilbene powder in food supplements?
