Is taking anthocyanin supplements as beneficial as eating anthocyanin foods? Overall, there’s still a lot to learn about the ways that supplementing with anthocyanins may be beneficial. As of now, experts recommend getting anthocyains from food sources rather than in isolated supplement form.
That being said, one review of 10 studies involving use of anthocyanin supplements found that supplementation significantly improved LDL cholesterol among diseased individuals or those with elevated biomarkers. However, supplementing did not significantly affect other markers of cardiovascular disease. No adverse effects of anthocyanins were reported when adults were takings up to 640 milligrams per day.
Examples of anthocyanins that can be isolated and taken as supplements include those called cyanidin and pelargonidin. Cyanidin is an isolated glycoside, a subset of anthocyanin that can be taken in supplement form to support the immune system. Pelargonidin is another anthocyanidin that has a characteristic orange color. These two supplements have been shown in some studies to to help fight oxidative stress and control blood glucose (sugar) levels. *
