Antioxidant, slows down cell aging. In case of deficiency (in diet) — increased oxidative stress. Prescribed for inflammations, cardiovascular diseases, to protect blood vessels and promote longevity.
Resveratrol — is a natural polyphenol with pronounced antioxidant and anti-inflammatory properties. It is found in grape skins, red wine, berries, and peanuts.
This nutrient is actively studied for its possible role in the prevention of cardiovascular diseases, support of metabolism, and protection of cells from oxidative stress.
Despite promising data, the effects of resveratrol on human health are not fully understood, and its effectiveness and safety depend on dosage and individual factors.
Therefore, it is important to approach its consumption consciously, especially when using supplements.
Health Benefits
has antioxidant effects and protects cells from free radicals;
reduces inflammation levels in the body;
promotes vasodilation and improves blood circulation;
The highest concentration of resveratrol is found in grape skins, so whole berries are preferable to juices.
The bioavailability from food is lower than from supplements, but the combination with other polyphenols enhances the effect.
Possible forms and their learnability
Nutrient forms are listed from best to worst:
Micronized trans-resveratrol. The same active form, but with improved bioavailability due to reduced particle size. It provides a more stable level in the blood, especially in extended-release capsules.
Trans-resveratrol. Biologically active form, but has low bioavailability and is quickly excreted. Effective only when combined with fats, quercetin, or piperine.

Although resveratrol is not classified as an essential nutrient, its deficiency in the diet may reduce the overall resistance of the body to oxidative stress and chronic inflammatory processes.
Potential Risks of Excess and Their Manifestations
digestive disorders (nausea, diarrhea);
excessive lowering of blood pressure;
effects on hormonal balance (phytoestrogenic activity);
possible disruption of the menstrual cycle or reduction in testosterone levels;
hepatotoxicity at high doses (especially in liver diseases);
possible drug interactions (anticoagulants, antihypertensive agents, etc.).
Safe consumption of resveratrol is usually up to 500 mg per day.
