In recent years the antioxidant qualities of the components of some plants and certain foods have been discovered. Pharmaceutical laboratories have extracted them to provide consumers with the daily amount needed to take advantage of their benefits. This is the case of resveratrol, which is talked about a lot lately.
From a pharmaceutical point of view, resveratrol is present on the market in the form of pills, tablets, sprays, and creams for topical applications. It is an increasingly popular product.
What are antioxidants?
Through breathing the human body performs its vital functions. The body generates free radicals when it interacts with fluids. These are electrons that, by not acting in pairs (hence the term “free”), damage healthy cells.
The consequences of the action of these electrons can cause both diseases and aging. It is the one we most commonly know as cell oxidation. Among the free radicals, we mention hypochlorous acid, superoxide, and hydroxyl and peroxyl radicals.
There are molecules contained in the substances of certain foods that prevent oxidation and its harmful effects. Experts claim that these molecules would directly influence a gene of latent longevity in animal organisms.
The following substances are considered antioxidants:
- Vitamins A, C, E
- Selenium and zinc
- The lutein
- Flavonoids and anthocyanins
These antioxidants are present in many foods. However, it may be necessary to consume them through food supplements to reach the recommended daily doses. This is the case with resveratrol.
Why is resveratrol an antioxidant?
Resveratrol contains the famous polyphenols that counteract the action of free radicals, thus avoiding the oxidative stress of cells. This process occurs through the contribution of electrons and hydrogen atoms that neutralize free radicals.
Resveratrol is a phytoalexin with powerful antimicrobial action. It is generated in high concentrations in some plants when they have undergone harmful radiation or bacterial or fungal infections.
Some of the polyphenols contained in resveratrol are proanthocyanidins, anthocyanins, and flavonoids. Its action is equivalent to that of caloric restriction that is associated with longevity.
The antioxidant action of resveratrol
Several studies try to determine the effectiveness of resveratrol from a medical point of view. Some say that the use of resveratrol can bring numerous health benefits such as:
- A general anti-aging effect.
- Prevention of diseases such as Alzheimer’s and Parkinson’s, acting on the accumulation of proteins.
- Regulation of bad cholesterol and an increase in good cholesterol.
- Protection of the cardiovascular system. Acts as an anti-coagulant and vasodilator.
- Inhibits abnormal cell production. Prevents the appearance of cancer, particularly of breast and prostate cancer.
- It allows the recovery of injuries caused by stroke.
- General anti-inflammatory action. It helps in the course of diseases.
- It regulates estrogen production in women.
- It has healing effects on neurodegenerative diseases, on respiratory diseases such as COPD and on liver diseases.
- It lowers blood sugar and has positive effects on metabolism, such as following a low-calorie diet.
- Improves the appearance and youthfulness of skin and hair.
As you have seen on this list, some effects of resveratrol are preventative and others are curative. We are talking about a revolutionary molecule that could have a huge impact on human health.
How much resveratrol should you take?
Depending on the characteristics of each person and considering different variables, we recommend a quantity between 250mg and 1000mg over a period of three months. You can also consume up to 3000 mg in eight weeks. These quantities can only be obtained by taking pharmaceutical products. Permanent consumption is not recommended.
Natural sources of resveratrol
Pharmaceutical extracts are very good and have high concentrations of this molecule. However, it is possible to obtain resveratrol directly from food, but in a smaller proportion and only as a preventive action for health.
Among the natural products, we can find resveratrol in red grapes, red wine, blackberries and almost all red berries, chocolate, peanuts, and walnuts. As for red wine, there may be some circumstances related to cultivation that could affect the amount of resveratrol present.
Precautions when taking resveratrol
The use of this substance should be avoided if platelet aggregation inhibitors, anticoagulants or drugs for liver diseases are being taken. In general, we advise you to consult a doctor who will be able to tell you which medications it is contraindicated to take this substance.
