ABSTRACT

Pterostilbene, a naturally occurring polyphenol, has garnered attention for its potent antioxidant, anti-inflammatory, and potential therapeutic properties. While blueberries are well-known as the primary dietary source, recent research has revealed its presence in other foods such as grapes, cranberries, nuts, and seeds. This review explores the chemical properties, bioavailability, and metabolic pathways of pterostilbene, emphasising its stability and superior absorption compared to its analogue, resveratrol. Additionally, the health benefits associated with its consumption are critically analysed, highlighting its roles in combating oxidative stress, reducing inflammation, and offering potential therapeutic effects against chronic diseases such as diabetes and cancer. Emerging dietary sources, including plant-based supplements, are discussed as alternative means to increase intake. The paper also provides practical dietary recommendations for incorporating pterostilbene into everyday nutrition and identifies gaps in current research, advocating for future studies to optimise its use as a functional food component. By expanding the focus beyond blueberries, this review underscores the broader dietary potential of pterostilbene in promoting health and preventing disease.
