Red Grape
(Vitis vinifera)

What It Is
Red grape comes from the fruit of Vitis vinifera and is naturally rich in plant polyphenols, including resveratrol, anthocyanins, and flavonoids. These compounds are most concentrated in the grape skin and have been widely explored for their role in antioxidant support and skin health.
In functional foods, red grape extracts are valued for delivering these naturally occurring plant compounds in a concentrated yet food-based form.
Why It’s Used in Functional Foods
Red grape is included in functional foods for its role in supporting the body’s natural antioxidant balance. Its polyphenols have been studied for how they interact with oxidative and inflammatory processes that influence skin structure, tone, and resilience over time.
Because skin is continually exposed to environmental stressors such as sunlight and pollution, polyphenol-rich ingredients like red grape are often chosen to help support skin from within.
How It Supports the Body
Research exploring red grape polyphenols highlights their involvement in helping the body manage everyday oxidative stress. This includes supporting the neutralisation of free radicals generated by environmental exposure, contributing to balanced inflammatory signalling, and helping protect cellular structures linked to skin firmness and elasticity.
Rather than acting on the skin directly, these compounds support the internal environment that influences how skin responds and adapts over time.
Skin Support Focus
Red grape polyphenols, particularly resveratrol, are frequently discussed in skin-related research for their role in supporting skin firmness, elasticity, and even tone. Studies suggest these compounds may help protect against oxidative processes associated with premature skin ageing and support immune and inflammatory balance relevant to skin comfort.
These effects are understood to occur through antioxidant activity and cellular signalling pathways connected to skin health, rather than through surface-level action.
Who It’s Commonly Chosen By
Red grape is often chosen by people looking to support skin vitality, radiance, and long-term resilience. It is commonly selected by those interested in protecting skin against environmental stressors and supporting even tone and texture as part of a broader skin nourishment approach.
Important Context
Red grape polyphenols are used in functional foods to support normal skin-related processes as part of a balanced diet. Their role is influenced by overall dietary patterns, consistency of intake, and individual physiology. Research helps describe how red grape compounds interact within biological systems, rather than predict specific outcomes.
This ingredient is shared for educational purposes, to support understanding of red grape as part of whole-food and functional nutrition approaches.
