Cinnamon

Cinnamon is a spice derived from the bark of trees in the Cinnamomum genus. Molecules found in cinnamon have antioxidant, antimicrobial, and anti-inflammatory properties. Supplementation with cinnamon might improve blood glucose, blood lipids, blood pressure, and some biomarkers of inflammation. However, cinnamon can have adverse effects when taken in large amounts.

Resveratrol

5 shared conditions Β· 318 outcomes

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.

Green Tea Extract

5 shared conditions Β· 110 outcomes

Green tea extract is obtained from green tea leaves and contains high levels of flavonoids, catechins like EGCG, and often caffeine. It might reduce oxidative stress biomarkers and cardiovascular disease risk factors and improve cognitive function. However, the quality of evidence is low to moderate, and high doses can cause liver damage.
