Resveratrol has been sold as a nutritional supplement for the last 5 or so years, yet the health benefits of this supplement are just now becoming more widely known, spoken about and recognised in mainstream media. Resveratrol is a type of polyphenol, an antioxidant compound found in many foods and plants such as blueberries, bilberries, cranberries, rhubarb and grapes…which is one of the reason studies cite the benefits of drinking a glass of red wine daily. Grapes naturally produce resveratrol on their skins as a natural defence mechanism to protect from pathogens, fungus, viruses and bacteria overgrowth.
As Hippocrates said, “let food be your medicine and medicine be your food”, the plants, berries and whole foods that we eat and are grown in our local environment can also provide our human bodies with needed nutrients for our own immune enhancement, and protection from dis-ease. Recent research on resveratrol indicates benefits for general and specific immune enhancement, heart health, cancer (by inhibiting angiogenesis inhibiting the development of new blood vessels which feed tumors), and inflammation. Studies also indicate benefit in reducing cholesterol in the body, namely by a reduction of LDL cholesterol (the harmful cholesterol) and triglyceride levels, reducing the risk of heart attacks and strokes.
The antioxidant effects of Resveratrol are also widely known, resveratrol helps to neutralise free radicals before they can damage healthy cells and protect cells damaged from environmental pollutants. Resveratrol also helps to decrease COX1, an enzyme that increases inflammatory substances which promote tumor growth. Resveratrol shows an ability to enhance life extension and healthy aging in clinical studies and promote longevity.
Studies have shown that resveratrol is difficult to absorb, thus for best absorption, combine its use with other bioflavinoids such as lutein or quercetin. Discontinue this supplement prior to surgery and consult your health care provider prior to use in pregnancy and lactation. Consult your holistic health care provider prior to use if taking anticoagulant medications.
