The health benefits of resveratrol for the cardiovascular system
1. Atherosclerosis & inflammation
Atherosclerosis is a condition characterized by the buildup of plaque in the arteries, which can lead to heart attack and stroke. Preliminary research in animal models shows that resveratrol may help to prevent the development and progression of atherosclerosis. [2]
Researchers have found that resveratrol may reduce the expression of adhesion molecules in endothelial cells. Adhesion molecules play a crucial role in recruiting white blood cells to the site of injury or infection. The reduction in adhesion molecule expression may help prevent the adhesion of white blood cells to the endothelial cells, thereby reducing the risk of atherosclerosis. [2]
Another study found that resveratrol reduced the expression of inflammatory markers in rabbits with atherosclerotic plaques. [3]
Inflammation is a key factor in the development of atherosclerosis. The immune system's response to damage caused by factors such as high blood pressure, high cholesterol, and smoking can lead to the accumulation of immune cells within the arterial wall, which can become foam cells and contribute to the formation of atherosclerotic plaques.
Inflammation can also stimulate the proliferation of smooth muscle cells within the arterial wall, further narrowing the artery and reducing blood flow.

2. Blood Pressure
High blood pressure (hypertension) is a major risk factor for cardiovascular diseases such as heart attack and stroke. Several studies have shown that resveratrol may help in regulating blood pressure. [5]
Researchers have found that resveratrol supplementation may result in lowered blood pressure. A clinical trial found that resveratrol supplementation may reduce systolic blood pressure in obese adults (systolic blood pressure is the pressure in the arteries when the heart beats) [6]
Another study found that resveratrol improved the ability of the arteries to expand in response to increased blood flow (also known as flow-mediated dilatation of the brachial artery or FMD). Impaired FMD is commonly associated with hypertension. [7]
3. Platelet Aggregation
Platelet aggregation is a critical step in the formation of blood clots. Animal models have shown that resveratrol may help in reducing platelet aggregation, thereby reducing the risk of dangerous blood clots and atherosclerosis. [8]
4. Endothelial Function
Endothelial function is the ability of the blood vessels to relax and dilate, allowing for better blood flow. Impaired endothelial function is a significant risk factor for cardiovascular diseases. Several studies have shown that resveratrol may help in improving endothelial function. [9]
For example, in a study published in the International Journal of Molecular Medicine, researchers found that resveratrol supplementation improved endothelial function in rabbits with high cholesterol. [10]
5. Cardioprotective Effects
Resveratrol has been shown to have cardioprotective effects, which may help reduce the risk of heart attack and stroke. In a study published in the Journal of Cardiovascular Pharmacology, researchers found that resveratrol may improve cardiac function in rats with an induced heart attack. [11]
Overall, the scientific evidence suggests that resveratrol has potential benefits for cardiovascular health. However, more research is needed to confirm these findings in human participants and to determine the optimal dosage and duration of resveratrol supplementation.
How to get resveratrol in your diet
Resveratrol is found in several food sources, including:
- Grapes and grape juice
- Berries (blueberries, raspberries, and cranberries)
- Peanuts and peanut butter
- Dark chocolate
- Moderate red wine consumption
However, the amount of resveratrol in these foods is relatively small. That means to obtain the therapeutic benefits of resveratrol, you may need to add a resveratrol supplement to your regime. Resveratrol supplements are available in various forms, including capsules, tablets, and liquids.
NutriRise Goddess Code Women's Multivitamin provides a convenient way for women to supplement their diets with resveratrol and other important nutrients for overall health and well-being. With its unique blend of vitamins, minerals, and antioxidants, this multivitamin is an excellent way for women to support their health and feel their best.
What are the potential side effects of resveratrol?
Resveratrol is generally considered safe for most people when taken in recommended doses. However, high doses of resveratrol may cause adverse effects, including:
- Digestive problems (such as nausea, diarrhea, and stomach cramps)
- Headaches
- Dizziness
- Allergic reactions
- Unintentional weight loss
It’s also important to take note of relevant drug interactions, since resveratrol may also interact with certain medications, including blood thinners and nonsteroidal anti-inflammatory drugs (NSAIDs). If you are taking any medications, you should talk to your healthcare provider before taking resveratrol supplements.
Final thoughts
Resveratrol is a natural polyphenol found in several foods, including grapes, berries, and peanuts. It has been shown to have potential benefits for cardiovascular health, including reducing the risk of heart disease and stroke. Resveratrol has antioxidant, antiplatelet, cardioprotective, and antiinflammatory activities, which make it a promising candidate for preventing and treating cardiovascular diseases.
While resveratrol supplements are available, it's important to remember that the best way to benefit from the health-boosting effects of resveratrol is through a healthy and balanced diet. Eating a variety of fruits, vegetables, and whole grains can provide you with the nutrients and phytochemicals your body needs to maintain optimal health.
Overall, resveratrol is a promising compound that may have a protective effect against the development of cardiovascular diseases. However, more research is needed to fully understand its potential benefits and optimal use in humans.
