Polyphenolic compound found in wine, with associated properties of a cardiovascular nature as well as of extending life expectancy. It can be found in Trans and Cis form, both of them being stable.
Resveratrol is a real fountain of youth, since it has a direct impact on the ageing process. It prevents the occurrence of atherosclerosis, reduces the level of bad cholesterol (LDL) in the blood, strengthens the immune system and prevents the appearance of Alzheimer's disease.
Some studies show how resveratrol may improve blood flow in the brain, which can reduce the likelihood of suffering a stroke.
Despite being found in other foods, only a small amount of resveratrol is found in active form once absorbed, hence many researchers have determined that its effect is rather poor.
What is resveratrol?
Resveratrol is a type of substance known as an stilbenoid, a kind of natural phenol and a phytoalexin which is synthesised naturally in various plants in response to injury or when they are under attack by bacteria or fungi and which has many beneficial properties. This substance is known as it is extracted from red grapes, from which red wine is made.
Resveratrol has amazing antioxidant properties. Antioxidants protect the body against damage that can lead to cancer and heart disease.
When we consider the potential health benefits provided by resveratrol, it isn't surprising that many manufacturers sell nutritional supplements containing resveratrol.
The health benefits of resveratrol
Prevention of cardiovascular diseases
Resveratrol is an anti-inflammatory and guards against the oxidation of bad cholesterol and prevents clots forming in the blood, which in turn can lead to a heart attack.
Another resveratrol benefit for our health is its use as a potential treatment against cancer. It is thought by doctors that resveratrol prevents the spread of cancer cells and that it therefore activates a process called "apoptosis", which encourages the destruction of cancer cells.
Other positive effects of resveratrol are related to Alzheimer's disease. Resveratrol protects nerve cells and prevents the appearance of damage, which in the long run can lead to Alzheimer's disease.
Resveratrol also has a positive effect on diabetes, since it helps to prevent insulin resistance, a process by which the body responds less to the impact of the hypoglycaemic insulin hormone.
Resveratrol and anti-ageing
Resveratrol helps to reduce oxidative stress and body swelling, thereby delaying the premature ageing of the organism.
A study performed on mice with an experimental group aged 12 months (equivalent to the human age of 40), showed that with a low fat, high calorie diet, combined with the consumption of resveratrol, they had an approximately 30% longer life when compared to the control group, being significantly less likely to suffer age-related health problems.
Although clinical trials have only been conducted on rodents, there is no doubt that resveratrol has an anti-ageing effect on humans too.
Resveratrol and heart function
In recent decades the effect of resveratrol on heart disease and cardiovascular health has been subject to thorough investigation.
The results of clinical studies conducted on animals are promising and have led to the first investigations in human patients with heart failure. The first results of the research point to the cardioprotective effect of resveratrol.
This is especially seen in the treatment of atherosclerosis (or deposits in the arteries), hypertension (high blood pressure), and ischaemia (reduction of the blood supply in the arteries) the most common heart problem. It has shown that resveratrol has a beneficial effect on these complaints.
A treatment with resveratrol, when compared to other methods, drastically reduces elevated blood pressure levels. It can also increase HDL levels (good cholesterol) in the blood.
Resveratrol and diabetes
According to "in vitro" studies, there is evidence that resveratrol has anti-diabetic properties.
Recent studies suggest that resveratrol improves insulin sensitivity and impaired glucose tolerance in obese adults with type II diabetes. This could be due to the effects of resveratrol, which improves mitochondrial function and inhibits inflammation.
Several studies have also shown that resveratrol can increase the adiponectin hormone content in the body. This hormone has different effects on glucose and lipid metabolism and in particular, increases the sensitivity of the cells to insulin.
The exact amount of resveratrol that is needed to produce this effect is still to be determined in further studies. But it is clear that long term resveratrol treatment benefits patients with type II mellitus diabetes.
Resveratrol and cancer
Experts believe that resveratrol can be an aid in the treatment of various types of cancer: breast, colorectal, and prostate, among others.
It is generally assumed that the aforementioned COX-2 is responsible for the increase of a hormone that produces inflammation, which can then give rise to cancer.
The results of clinical studies have concluded that resveratrol can inhibit COX-2 enzymes, which is why there are many scientists who have great expectations regarding the treatment of cancer with resveratrol. There are currently many studies underway to find a drug based on resveratrol with which to fight cancer.
Who are resveratrol capsules useful for?
For people who want to strengthen their cardiovascular system. Researchers have found that resveratrol protects the heart and can prevent the onset of heart problems.
Those who want to protect themselves from cancer. A recent study showed that resveratrol may curb the development of cancer cells and is an effective anti-cancer agent.
People who want to improve their vision. Researchers have discovered that resveratrol has the ability to modulate angiogenesis (the growth of blood vessels) and can prevent their abnormal growth, which can negatively affects the vision.
Those who need to increase testosterone levels. According to different studies, when resveratrol is taken for a period of 28 days, it increases the testosterone level by over 50% in blood.
For people who do sports and strength workouts since resveratrol has a positive effect on the muscles and bones.
The exact dose of resveratrol depends on individual factors for each person, such as their health, age, sex and particular circumstances.
There is still no solid scientific information on the optimal dose of resveratrol. However, it is completely safe to take, as it is a completely natural product. A reasonable approach is to respect the doses indicated for the nutritional supplement.
What should we take resveratrol capsules for?
To protect cells from damage caused by free radicals
To curb the spread of cancer, notably prostate cancer
