Muscadine Health Research Links

Here are numerous links summarizing the incredible research conducted on muscadine grape seeds’ effect on human health. If you are new to the internet, the links below are embedded in the words and you access them by clicking the underlined (or highlighted) words, which will then open the linked websites in a new window.  Using “Ctrl-F” you can “find” a specific document by typing the word(s) for which you’re searching.  (You can also use the Search box at the top-right on this page.)

If you search, you’ll see that there have been over 2,500 studies on red wine, over 800 studies on grape seeds, and over 600 studies on red grapes.  Red wine and red grapes are incredibly healthy and the studies on heart health and longevity have been nothing short of amazing. But muscadines actually take all the health benefits of the red grape and ‘kick it up a notch’.” –
