So, rather than getting absorbed into the body through the small intestine, they arrive at the colon fully intact. Once there, the good bacteria that hang out in the colon chow down on them, using them for food, she explains. As it turns out, this process is where much of the gut health magic of polyphenols lies.\u00a0<\/span><\/p>\n<h2><strong>Exactly How Polyphenols Support Gut Health<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">You see, as gut bacteria consume and ferment polyphenols, several compounds (called metabolites) are released that aren\u2019t produced during the digestion of other antioxidants, <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/letter-vitamins\" target=\"_blank\" rel=\"noopener\">vitamins<\/a>, or <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/minerals\" target=\"_blank\" rel=\"noopener\">minerals<\/a>. These microbial metabolites have been shown to support digestive function and promote overall health, Volpe shares.<\/span><\/p>\n<p>Also, by serving as food for good gut bugs, polyphenols help your microbiome flourish. <span style=\"font-weight: 400;\">Indeed, while these compounds are officially categorized as antioxidants, they also function like <a href=\"https:\/\/www.vitaminshoppe.com\/c\/digestion-gut-health\/fiber\" target=\"_blank\" rel=\"noopener\">prebiotics<\/a>, says Volpe.<\/span><\/p>\n<p><strong>Read More: <a href=\"https:\/\/www.vitaminshoppe.com\/blog\/gut-health-game-changers\/\" target=\"_blank\" rel=\"noopener\">7 Dietitians Share Their Biggest Gut Health Game-Changers<\/a><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">\u201cPrebiotics feed and promote the growth of health-supporting microbes in our gut,\u201d she says. By doubling as fuel for your beneficial gut bacteria, polyphenols help nourish the entire gut ecosystem and promote a more diverse and resilient microbiome.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Greater gut diversity may sound like small potatoes, but it\u2019s a big deal. <\/span><span style=\"font-weight: 400;\">Time<\/span><span style=\"font-weight: 400;\"> and <\/span><span style=\"font-weight: 400;\">again<\/span><span style=\"font-weight: 400;\">, research (like <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6682904\/\" target=\"_blank\" rel=\"noopener\">this study<\/a> and <a href=\"https:\/\/www.frontiersin.org\/journals\/microbiology\/articles\/10.3389\/fmicb.2022.999001\/full\" target=\"_blank\" rel=\"noopener\">this study<\/a>) has shown that an increase in beneficial bacteria significantly benefits digestive health and overall well-being. In fact, a February 2025 review in <\/span><a href=\"https:\/\/www.mdpi.com\/1422-0067\/26\/3\/1335\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400;\">The International Journal of Molecular Sciences<\/span><\/i><\/a><span style=\"font-weight: 400;\"> found that increasing polyphenol consumption enhances gut microbe diversity <em>and<\/em> function. The researchers note that this effect ultimately has the power to meaningfully support digestion and whole-body health.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By supporting cellular health and gut function, polyphenol intake may help lower the risk of chronic conditions that affect cardiovascular health, brain health, metabolic function, and blood sugar regulation, adds Volpe.<\/span><\/p>\n<h2><strong>Where To Find Polyphenols In Food\u00a0<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">The best way to make sure your diet is peppered with polyphenols is to <a href=\"https:\/\/www.vitaminshoppe.com\/blog\/eat-the-rainbow\/\" target=\"_blank\" rel=\"noopener\">eat the rainbow<\/a>. \u201cA wholesome and nutritionally balanced diet that includes a variety of fruits, vegetables, whole grains, herbs, and spices will be rich in polyphenols,\u201d says Volpe.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In particular, she suggests narrowing in on these colorful eats:\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Fruit:<\/b><span style=\"font-weight: 400;\"> Apples, plums, pomegranate seeds, grapes, citrus fruits, and berries<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Vegetables:<\/b><span style=\"font-weight: 400;\"> Onions, bell peppers, tomatoes, and purple carrots<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Whole grains: <\/b><span style=\"font-weight: 400;\">Oats and buckwheat<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Other: <\/b><span style=\"font-weight: 400;\"><a href=\"https:\/\/www.vitaminshoppe.com\/p\/organic-matcha-mushroom-powder-unflavored-30-powder\/vs-5203\" target=\"_blank\" rel=\"noopener\">Matcha<\/a>, <a href=\"https:\/\/www.vitaminshoppe.com\/c\/herbs-natural-remedies\/herbal-teas\/green-tea\">green tea<\/a>, cacao powder, rooibos, and <a href=\"https:\/\/www.vitaminshoppe.com\/c\/food-drinks\/drinks\/coffee-tea\" target=\"_blank\" rel=\"noopener\">coffee<\/a><\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Volpe also recommends opting for organic produce and grains whenever possible. \u201cGlyphosate, a popular herbicide used in the United States food supply, <\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10330715\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">has been shown<\/span><\/a><span style=\"font-weight: 400;\"> to negatively impact gut health by reducing the presence of certain healthy bacteria like <\/span><i><span style=\"font-weight: 400;\">Lactobacillus <\/span><\/i><span style=\"font-weight: 400;\">and <\/span><i><span style=\"font-weight: 400;\">Bifidobacterium<\/span><\/i><span style=\"font-weight: 400;\">,\u201d she says. Taking that extra step when budgeting and shopping can really make a difference, especially over time.<\/span><\/p>\n<h2><strong>What To Know About Polyphenol Supplements<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">A nutrient-dense diet is a non-negotiable for sound gut health. However, a polyphenol supplement can provide a benefit boost to some people, Volpe suggests. For example, people experiencing gut symptoms that may be linked to low microbial diversity (like bloating, irregular digestion, or sluggish motility) often notice improved GI function while supplementing with polyphenols, she says.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Polyphenol supplements are usually derived from real foods. And, because all fruits, vegetables, and herbs have a different polyphenol makeup, the specific compounds in the supplements derived from these eats varies. \u201c<a href=\"https:\/\/www.vitaminshoppe.com\/p\/pomegranate-extract-250-mg-100-veggie-caps\/vs-2220\" target=\"_blank\" rel=\"noopener\">Pomegranate extract<\/a>, <a href=\"https:\/\/www.vitaminshoppe.com\/p\/triple-strength-green-tea-extract-200-vegetarian-capsules\/vs-1808\" target=\"_blank\" rel=\"noopener\">green tea extract<\/a>, <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/supplements\/super-greens-superfoods\" target=\"_blank\" rel=\"noopener\">reds powders<\/a>, and <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/supplements\/super-greens-superfoods\" target=\"_blank\" rel=\"noopener\">greens powders<\/a> can all offer gut health benefits\u2014so long as they&#8217;re high quality and well tolerated,\u201d Volpe says.

That&#8217;s why it&#8217;s important to follow package instructions and take a moderate approach to adding supplements to your routine.
