What is Resveratrol: the health benefits of resveratrol supplements

Dec 13,2023 | Kevin Aidevi

Within the realm of health, resveratrol stands out as a captivating compound, exerting a diverse influence on well-being. Derived from red wine, grapes, berries, and peanuts, resveratrol is a potent antioxidant, poised to address various health issues. This article explores its origins, benefits, and ongoing scientific investigations.


What is Resveratrol?

Resveratrol, functioning as an antioxidant, is a plant compound primarily found in red wine, grapes, certain berries, and peanuts. Its highest concentrations are typically found in the skins and seeds of grapes and berries, which are integral components in the fermentation process of red wine, contributing to its notably elevated resveratrol content.

Despite the predominant focus of research on resveratrol being conducted in animals and test tubes with substantial compound doses, the limited studies involving humans have mainly explored supplemental forms of resveratrol at concentrations surpassing those achievable through regular dietary intake.


Health Benefits of Resveratrol

Promotes Cardiovascular Health: Resveratrol is extensively studied for its potential heart health benefits, including reducing blood pressure and improving cholesterol levels. Its antioxidant effects may lower systolic and diastolic blood pressure, protecting against stroke. Resveratrol improves endothelial function, reducing vascular oxidative stress and arterial stiffness for healthy blood flow, guarding against heart disease. Additionally, it lowers total cholesterol and triglycerides, with a particular decrease in "bad" LDL cholesterol, further contributing to heart health.

May Help Lower Blood Pressure: Due to its antioxidant properties, resveratrol shows promise as a supplement for reducing blood pressure. A 2015 review suggested that high doses may alleviate the pressure on artery walls during heartbeats, specifically targeting systolic blood pressure—the upper number in blood pressure readings. Elevated systolic blood pressure, often associated with aging and arterial stiffness, poses a risk for heart disease. Resveratrol potentially achieves this blood-pressure-lowering effect by promoting the production of nitric oxide, inducing blood vessel relaxation. Nonetheless, the authors caution that further research is necessary to determine the optimal resveratrol dosage for maximizing blood pressure benefits before specific recommendations can be made.

Good for the Brain: Drinking red wine may help maintain cognitive sharpness with age due to resveratrol, an antioxidant with anti-inflammatory properties. Resveratrol appears to hinder Alzheimer's-related plaque formation and initiates protective processes for brain cells. However, the effectiveness of resveratrol supplements for brain protection is still being studied, and recommendations are not widespread.

Promotes a Healthy Metabolism: Resveratrol, found in certain foods, supports metabolism by helping control blood sugar and improving insulin response, potentially reducing the risk of type 2 diabetes. For those with type 2 diabetes, resveratrol supplements have demonstrated benefits in enhancing insulin sensitivity, lowering blood sugar levels, and reducing stress on the body, protecting against complications like heart disease. Another study found that a daily 500 mg resveratrol dose over three months led to weight loss, smaller waists, and improved fat metabolism in people with metabolic syndrome, lowering the risk of stroke, heart disease, and type 2 diabetes.

May Protect Against Cancer : Scientists are studying resveratrol to see if it can be used to prevent cancer or as an extra treatment alongside existing cancer therapies. In tests conducted on cells and animals, resveratrol has shown promising anticancer properties, suggesting it might play a role in preventing or combatting various types of cancer, such as breast, colon, gastric, pancreas, prostate, ovarian, and endometrial cancers.


Other Benefits

Promoting Longevity: Research in animal models suggests that resveratrol's antioxidant effects may activate cellular pathways linked to longevity and the reduction of age-related diseases.

Allergy Relief: A nasal spray with resveratrol may alleviate symptoms in individuals with seasonal allergies, particularly hay fever.

Healthy Skin: Resveratrol could enhance skin health by reducing inflammation, promoting collagen production, and safeguarding against UV radiation damage.

Eye Protection: Resveratrol's ability to combat oxidative stress may offer protection against age-related macular degeneration, a common eye disease leading to vision loss.

Immune System Boost: Low doses of resveratrol may support immune system function by enhancing antioxidant activity and reducing inflammation.
