    After consumption, 77-80% of resveratrol gets absorbed into the bloodstream through active transport via the intestinal epithelial cells. Once in the bloodstream, it associates with albumin and lipoproteins. Despite its efficient absorption, resveratrol possesses a short half-life of around 1.5 hours. This is attributed to its rapid absorption in the intestine and subsequent degradation in the liver. A significant amount of ingested resveratrol, approximately 49–61%, is eventually excreted through urine. [1]

    1. Galiniak S et al.: Health benefits of resveratrol administration. Acta Biochim Pol 2019. (PMID 30816367) [PubMed] [DOI] Resveratrol is a polyphenol that is abundant in grape skin and seeds. Food sources of resveratrol include wine, berries, and peanuts. This compound has many properties, including activity against glycation, oxidative stress, inflammation, neurodegeneration, several types of cancer, and aging. Because resveratrol is generally  welltolerated, it is believed to be a promising compound in preventing many diseases, such as diabetes and its complications. Unfortunately, this compound exhibits low bioavailability and solubility. The aim of this review is to summarize the latest information on the multiple effects of resveratrol on health and the benefits of its intake, based on in vitro and in vivo studies in animals and humans.
