Resveratrol: A Comprehensive Review of its Potential Health Benefits and Risks

From: National Library of Medicine, Drugs, Herbs and Supplements, Herbs and Supplements-- Resveratrol

Resveratrol is a natural chemical that can be found in various plants, including red grapes, berries, peanuts, and Polygonum cuspidatum. It has been studied extensively for its potential health benefits, which range from reducing inflammation and blood pressure to reducing the risk of cancer and cardiovascular disease. However, there is still much debate among researchers and healthcare professionals regarding the efficacy and safety of resveratrol in humans. In this comprehensive review, we will explore the current research on the potential health benefits and risks of using resveratrol as a dietary supplement or as an ingredient in skincare products.

History and Sources of Resveratrol:
Resveratrol was first isolated in 1940 from the roots of the white hellebore plant by Japanese scientists. It wasn't until the late 1990s that resveratrol gained worldwide attention due to its association with the "French Paradox" – the observation that despite consuming a diet high in saturated fats, the French population had a lower incidence of coronary heart disease than other Western countries. This paradox was attributed to the consumption of red wine, which is rich in resveratrol.

Resveratrol is found mainly in the skins of red grapes but is also present in lesser amounts in red wine, grape juice, and some fruits and nuts. Despite being found in many food sources, the concentration of resveratrol varies widely depending on varietal, growing conditions, and processing techniques. It is estimated that a glass of red wine contains approximately 0.2-5.8 mg of resveratrol, while a handful of peanuts contains around 1.3 mg. To achieve the therapeutic dose of resveratrol used in some studies, supplements are often required.

Potential Health Benefits of Resveratrol:

Anti-inflammatory properties: Resveratrol has been shown to reduce inflammation in various animal models and in vitro studies. In humans, some studies suggest that resveratrol may lower levels of inflammatory markers such as C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-alpha).

Cardiovascular health: Resveratrol is believed to have cardioprotective effects due to its ability to reduce oxidative stress, inflammation, and platelet aggregation. It has been studied for its potential to reduce blood pressure, improve lipid profiles, and prevent atherosclerosis.

Cancer prevention: Resveratrol has been shown to inhibit the growth of cancer cells in animal models and in vitro studies. Some human studies have suggested that high resveratrol intake may be associated with a lower risk of certain cancers, including breast cancer, colon cancer, and prostate cancer.

Neuroprotection: Resveratrol is thought to exert neuroprotective effects by reducing inflammation, oxidative stress, and beta-amyloid plaques, which are characteristic of Alzheimer's disease. Animal studies have suggested that resveratrol may improve memory and cognition.

Anti-diabetic effects: Resveratrol has been shown to improve insulin sensitivity and glucose uptake in animal models and in vitro studies. Some human studies suggest that resveratrol may improve glycemic control in people with type 2 diabetes.

Other potential benefits: Resveratrol has also been studied for its potential to improve bone health, protect against liver disease, and promote longevity.

Limitations and Risks of Resveratrol:
Despite the promising results from animal and in vitro studies, there is still limited evidence to support the use of resveratrol in humans. Many of the human studies conducted on resveratrol have been small-scale, short-term, and of low quality. Furthermore, the dosages and formulations used in these studies have varied widely, making it difficult to draw definitive conclusions.

Additionally, resveratrol has some potential risks that need to be considered. While resveratrol is generally considered safe when taken in small amounts found in foods, high doses may cause side effects such as gastrointestinal problems, headaches, and dizziness. Resveratrol supplements may also interact with certain medications, including blood thinners, immunosuppressants, and some chemotherapy drugs. Pregnant and breastfeeding women should avoid using resveratrol supplements, as there is not enough evidence to determine their safety in these populations.

Resveratrol is a natural chemical that has gained widespread attention for its potential health benefits, including reducing inflammation, improving cardiovascular health, and preventing cancer. While many animal and in vitro studies have shown promising results, more high-quality human studies are needed to determine its efficacy and safety. Furthermore, the dosages and formulations used in these studies need to be standardized for better comparison. Despite its potential benefits, resveratrol supplements should be used cautiously, especially by those taking medication or with underlying medical conditions.
