Resveratrol Supplement Ingredient

Impact

High effect

Typical dose:100–500 mg

Resveratrol's benefits for brain circulation and its antioxidant properties are well-supported.

Study evidence

Resveratrol may improve selected aspects of cognition, particularly in some research involving older adults and postmenopausal women, but results are inconsistent. The available evidence does not establish a reliable overall memory benefit or show that supplementation prevents dementia.

Metabolism Boost

Impact

High effect

Typical dose:100–500 mg

Resveratrol has been shown to increase the number and efficiency of mitochondria, the cellular powerhouses where fuel is burned. By activating the SIRT1 gene, it can improve glucose homeostasis and increase fatty acid oxidation, effectively making cellular energy production more robust and efficient.

Study evidence

21 studies

Resveratrol may improve some measures of blood sugar and lipid metabolism, especially in people with metabolic disorders. However, results are inconsistent, and improved metabolic markers do not mean a faster metabolism: the supplied evidence does not establish increased calorie burning or reliable weight loss.

Skin Health

Impact

High effect

Typical dose:100–500 mg

Resveratrol activates sirtuins, proteins associated with cellular longevity, and provides powerful antioxidant protection against free radical damage from sun exposure and pollution. This helps to preserve collagen and elastin, reducing signs of premature aging.

Study evidence

7 studies

Resveratrol shows preliminary promise for selected skin concerns, especially in topical preparations or combined oral and topical use. Evidence for an oral supplement alone is limited, and improvements in wrinkles, acne, or wound care do not establish a broad skin-health benefit.

Anti-Aging

Impact

Moderate effect

Typical dose:150–1000 mg

Resveratrol mimics some of the effects of caloric restriction, a known longevity intervention. While human data is still evolving, it shows consistent benefits for endothelial function and metabolic health, making it a key supplement for vascular aging.

Study evidence

7 studies

Resveratrol has shown benefits for selected age-related outcomes, such as bone density or certain skin changes, but human findings are mixed. The available evidence does not establish that oral Resveratrol slows overall aging or extends life, and some skin benefits involve combined treatments.

Vision Support

Impact

Moderate effect

Typical dose:100–500 mg

Resveratrol helps combat oxidative stress and inhibits inflammatory pathways implicated in age-related macular degeneration (AMD) and diabetic retinopathy. It supports mitochondrial function in the high-energy environment of the retina, potentially preserving photoreceptor health.

Study evidence

4 studies

Resveratrol-containing supplements have shown limited promise as additions to medical treatment for certain retinal diseases, but they have not consistently improved visual acuity. The available evidence does not establish that Resveratrol alone protects eyesight or benefits people with healthy eyes.

Anti-Inflammatory Support

Impact

Situational effect

Typical dose:150–500 mg

Found in grapes, resveratrol has demonstrated an ability to inhibit key inflammatory molecules like NF-kB and various cytokines. Its benefits are often linked to cellular longevity and metabolic health, making it a supportive agent for managing age-related or metabolically-driven inflammation.

Study evidence

34 studies

Resveratrol may lower some inflammatory blood markers, especially in selected metabolic or inflammatory conditions, but results are inconsistent. Several controlled trials found no benefit, and the evidence does not establish reliable relief of inflammatory symptoms or broad protection from disease.
