Benefits of Resveratrol

Studies have indicated that consuming Resveratrol may improve brain health, metabolic health, and cell health.  In particular, resveratrol has been shown to 

  • improve Alzheimer's Disease biomarkers

  • improve brain function in certain populations

  • relieve depression and stress

  • improve the health of Diabetics

  • improve cardiovascular function

  • fight cancer

Alzheimer’s Disease​

Resveratrol supplements were shown to:

  • Stabilize a biomarkers indicating Alzheimer’s disease progression (i.e., Abeta40, which decreases as dementia worsens and Alzheimer’s disease progresses.  In patients taking resveratrol, Abeta40 stabilized)

  • Reduce brain inflammation.

  • Stabilize the blood brain barrier (why is this important),

  • Be safe and well tolerated. [1], [2], [3]

 

Improved Brain Function 

Resveratrol supplements were shown to:

  • Improve cognitive function in post-menopausal women. [4], [5]

  • Increase brain blood-flow in healthy adults during task performance and also in patients with type 2 diabetes. [6], [7]

Depression & Stress 

Resveratrol supplements were shown to:

  • Decrease the expression of stress related enzyme phosphodiesterase 4 (PDE4) in a dose dependent manner. [8]

  • Inhibit the expression of depression related enzyme MAO-A (which removes  neurotransmitters norepinephrine, serotonin and dopamine from the brain).

  • Increase the expression of serotonin and noradrenaline levels in the brain.  For their parts, low serotonin levels can create feelings of sadness, depression, hopelessness, irritability, and anxiety and low noradrenaline levels can increase anxiety and blood pressure. [9]

Diabetes

Resveratrol supplements were shown to:

  • Improve insulin sensitivity and reduce oxidative stress in Type II diabetic patients.[10], [11], [12]

  • Improve insulin resistance.  [13]

  • Reduce arterial stiffness in Type II diabetic patients. [14]

Heart & Circulation

Resveratrol supplements were shown to:​

  • Improve flow mediated dilation and endothelial function in healthy obese adults, adults with mildly elevated blood pressure, and adults with metabolic syndrome. [15], [16], [17]

  • Inhibit blood platelet aggregation (which helps prevent dangerous blood clots). [18]

  • Help prevent atherosclerosis (disease characterized by deposits of plaque on the artery inner walls). [19]

Cancer

Resveratrol supplements were shown to:

  • Potentially decrease the risk of colon cancer development in low doses (resveratrol containing grape powder) and increase the death of cancer cells vs. placebo in patients with colon cancer in high doses (5g resveratrol/day)

  • Significantly reduce (at 2.5 g resveratrol/day) IGF1 and IGFBP3 levels in plasma, which indicates that resveratrol is a chemopreventative agent in humans.

  • Increased the activity/protein levels of numerous carcinogen-detoxifying enzymes (e.g., glutathione S-transferase and glucuronosyltransferase). [20], [21]
