Others are anti-inflammatory in nature. Not all cytokines are immune system cells, but every cytokine has an impact on how the immune system functions. In vitro and in vivo studies show resveratrol reduces chronic inflammation by suppressing the following pro-inflammatory cytokines :.
Resveratrol also appears to reduce inflammation by regulating SIRT1 and NF-KB pathways, two signalling networks that play a crucial role in modulating the inflammation response.
Mitochondria are often referred to as the powerhouses of the body. Every cell contains many of these tiny organelles, and each is responsible for converting food molecules into energy for the cells, tissues, organs, and organisms to function.
However, mitochondria become dysfunctional with age. Along with oxidative stress, mitochondrial dysfunction is believed to be ageing and age-related disease. In some studies, resveratrol appears to keep these vital organelles healthier, and longer—a benefit that may promote healthy metabolism and ageing.
This appears to be achieved primarily through the activation of SIRT1 and mTOR , two critical protein networks known to govern fundamental cellular longevity mechanisms. Several foods contain resveratrol. However, supplements may be needed to obtain therapeutic doses and significant health benefits.
For more information, see the following section, Resveratrol Dosages and Supplements. In the book, Discovery and Development of Anti-Breast Cancer Agents from Natural Products, authors identify four of naturally occurring cis-resveratrol.
They include:. Of course, not all these plants are common food items. Additional foods that are known to contain resveratrol include pistachios, cranberries, bilberries, and dark chocolate, although the authors did not include them in the publication. Disclaimer: Always consult your health care professional before making changes in your diet or exercise regimen, including the use of supplements like resveratrol or trans-resveratrol.
Doses up to seem generally well-tolerated. Dosages in excess of 3,mg may cause unwanted side effects, including nausea and upset stomach. Resveratrol is known to have poor bioavailability. However, the plant compound can be synthesized into several derivatives with better absorption and therapeutic potential.
Pterostilbene was found to have far greater lipophilicity , meaning it can more easily dissolve into fats, oils, and other lipids. With these key insights, researchers have been able to further modify resveratrol to increase bioavailability and absorption. Specifically, the development of solid lipid nanoparticles and unique lipid carrier systems are two key achievements that increase absorption by up to 3.
One of the more interesting things about resveratrol is its ability to have a relatively wide distribution. From enzymes to cytokines and even DNA, resveratrol appears to have an impact on many key pieces of fundamental biology.
One point worth emphasizing: Activation of the SIRT1 pathway is a key element to healthy ageing. In a study published by The Journal of Physiological Sciences , researchers found that resveratrol promotes mitochondrial function, improves physical endurance, and reduces oxidative stress.
Notably, researchers observed increased antioxidant activity via the up-regulation of enzymes like CAT and SOD. Researchers also observed better regulation of mitochondrial function due to increased antioxidant capacity and balance. By improving mitochondrial health, resveratrol may also help to prevent certain diseases.
In a study , it was found to improve kidney function in mice with renal injury. Resveratrol supplements may help to reduce blood pressure. For example, a study published by the International Journal of Molecular Science showed resveratrol to reduce oxidative stress and improve arterial stiffness.
Hardening of the arteries is a major contributing factor to high blood pressure. Therefore, foods, lifestyle practices, and supplements that promote arterial health are considered essential for healthy aging. Additionally, resveratrol appears to improve the health of endothelial cells, or the cells that line blood vessels.
In a study published by the journal Molecules , researchers found resveratrol to increase endothelial nitric oxide NO production by up-regulating the enzyme eNOS. NO is known to relax blood vessels, which in turn lowers blood pressure. Beyond antioxidant capacity, resveratrol appears to reduce systolic blood pressure too.
Systolic pressure is a measurement of the pressure exerted when the heart pumps blood out and into the body. As mentioned above, this number tends to increase with age and arterial stiffening. In a meta-analysis of six randomized controlled human trials, researchers found resveratrol doses of mg or more to reduce systolic blood pressure significantly.
Although potentially beneficial for individuals with high blood pressure, there are complications. Resveratrol may have an adverse reaction with blood pressure medications and certain other drugs.
For more information, see the Potential Side Effects and Drug Interactions section below. In recent studies, resveratrol has also demonstrated the ability to improve overall blood lipids. Blood lipids are fats in the bloodstream, and the two most common are HDL and LDL. LDL tends to accumulate over time, especially in western cultures where poor diet and sedentary lifestyles are common.
However, animal studies indicate resveratrol may help. In , a study published by Life Sciences showed that mice with hyperlipidemia high LDL experienced both weight loss and a decrease in total cholesterol following resveratrol treatments.
New research suggests LDL oxidation may contribute to arterial plaque buildup, and thus increased blood pressure. In a human trial , individuals who consumed resveratrol supplements showed a 4.
Arthritis, a form of joint degeneration that causes pain and disability, is a common condition among aging populations. According to the U. Centers for Disease Control , arthritis:. Over-the-counter anti-inflammatory medicines, like non-steroidal anti-inflammatories NSAIDs , are one of the most common methods of treating arthritis pain.
However, NSAIDs can be a dangerous medicine when used chronically. Most consumers are unaware that the U. Food and Drug Administration has explicitly cautioned the public against long-term use of NSAIDs like Motrin and Advil, warning that chronic use can cause heart attacks or strokes.
Natural anti-inflammatories, like resveratrol, may provide substantial relief. Whereas NSAIDs may cause potentially harmful cardiac and neurological events, the studies described above illustrate how resveratrol may do the exact opposite by reducing blood pressure, improving blood lipids, and promoting cardiac health.
In one study , resveratrol injections were shown to ameliorate arthritis symptoms by preventing cartilage breakdown. An astonishing 1 in 10 Americans totaling more than 33 million people have type 2 diabetes. As insulin resistance builds, the body loses its ability to extract glucose sugar from the bloodstream for things like energy, hydration, and tissue repair.
This causes several adverse health conditions over time, including high blood pressure, excess body fat, and increased risk of cardiovascular disease.
Early research shows that topically applied resveratrol shows some promise in improving age spots and elasticity of the skin, as well as reducing acne, but more research is needed in this area.
The dosage for resveratrol depends on the person and what it is being used for, so check with your doctor. It is thought to be safe in doses up to 1, milligrams daily. Higher doses can cause stomach problems such as nausea, vomiting and diarrhea. Resveratrol might interact with blood thinners and NSAID medications such as ibuprofen.
Red wine, red grapes particularly the skins , purple grape juice, mulberries and peanuts all contain resveratrol. Resveratrol supplements can be found in capsule, powder and liquid form. Sources: WebMD, Healthline, National Institutes of Health. You must be logged in to post a comment.

Metabolism boosters before Dosagr go popping any Metabolism boosters doosage supplement you find on Resveratol store shelves, read on to learn all the ins and outs of what this potent ingredient has to offer. Resveratrol belongs to a class of organic chemicals known as polyphenols, which can be found in numerous foods you consume on a daily basis. Polyphenols act as antioxidants in the body, helping to eliminate free radicals and fight oxidative stress. Resveratrol is a specific polyphenol found in grapes, tea leaves, blueberries, and peanuts. Resveratrol helps to protect grapes from the deleterious effects of bacteria and fungi that would otherwise spoil the plant. However, it is worth mentioning that the concentration of resveratrol in red wine is much, MUCH lower than what can be found in the skins of grapes.
