Resveratrol: What it Does, How to Use It, and Safety
Resveratrol is the plant compound people talk about when they mention red wine and anti-aging. The truth is simpler: it’s a bioactive molecule found in grape skins, berries, and peanuts that shows promising effects in lab tests and some human studies. If you’re thinking about trying it, here’s what actually matters—what works, what’s risky, and how to pick a product that won’t waste your money.
Benefits backed by research
Resveratrol has been studied for heart, metabolic, and cell-protecting effects. Animal studies show clear benefits for blood vessel function and inflammation. In humans, small trials report modest improvements in insulin sensitivity and markers of inflammation for people with metabolic issues. It’s not a miracle—results vary by dose and the health of the person taking it—but it does seem to offer measurable effects in specific situations.
Another area is circulation: some trials found improved blood flow and lower blood pressure in people taking higher doses. Still, larger and longer studies are needed to confirm long-term benefits and who gains the most.
How to pick and use supplements safely
Form matters. Look for "trans-resveratrol" on the label—this is the active form most studies used. Third-party testing (USP, NSF, or a COA from the manufacturer) is a good sign. Avoid products that don’t list the exact resveratrol content or that mix it with vague “proprietary blends.”
Dosing: common supplement doses run from 100 to 500 mg daily. Many clinical trials use 150–500 mg/day; some short-term trials used up to 1,000 mg/day with monitoring. Start low and watch how you feel. Taking resveratrol with a fatty meal can boost absorption because it’s fat-soluble.
Watch for interactions and side effects. Resveratrol can thin the blood and may increase bleeding risk—so talk to your doctor if you use blood thinners like warfarin, or plan surgery. It can also affect liver enzymes (CYP), which may change how other drugs work. Some people report stomach upset, headache, or sleep changes at high doses.
Who should avoid it? Pregnant or breastfeeding people, anyone on strong anticoagulants, and people on multiple prescription drugs should check with a clinician before starting resveratrol. Kids aren’t well studied, so skip it unless a doctor advises otherwise.
Final tips: choose a reputable brand, start with a low dose, take with food, and keep your healthcare team in the loop—especially if you take other medications. Resveratrol isn’t a miracle cure, but used smartly it can be a useful part of a broader approach to heart and metabolic health.
