Ingredients explained
Trans-Resveratrol (from Japanese Knotweed root extract)
Trans-resveratrol acts as a polyphenol antioxidant that may help neutralize free radicals and influence cell signaling pathways linked to cellular defense and healthy aging processes.
Caution: May interact with certain medications and can have mild gastrointestinal effects; take with food if sensitive and consult a professional if using medications.
Green Tea Extract (standardized to 95% polyphenols, 60% EGCG)
EGCG and other catechins function as antioxidants and may support cellular protection by scavenging free radicals and modulating oxidative stress pathways.
Caution: Contains natural caffeine traces which may affect sleep or sensitivity; reduce use near bedtime if you are sensitive to stimulants.
Grape Seed Extract (95% proanthocyanidins)
Proanthocyanidins provide antioxidant activity that may support vascular function and protect tissues from oxidative stress.
Caution: May increase sensitivity in people prone to headaches or with tannin sensitivity; consider taking with food.
Quercetin
Quercetin is a flavonoid that may modulate oxidative stress and inflammatory signaling, supporting cellular resilience.
Caution: May interact with certain medications; start with the suggested serving to assess tolerance.
Vitamin C (as ascorbic acid)
Vitamin C acts as a water-soluble antioxidant that donates electrons to help protect cells and regenerate other antioxidants such as vitamin E.
Caution: Large amounts can cause digestive discomfort; follow the suggested use if you have a sensitive stomach.
How they work together
Trans-resveratrol and quercetin offer complementary polyphenol actions on cellular signaling and oxidative balance. Grape-derived polyphenols and green tea catechins add broad-spectrum antioxidant support across water- and lipid-phase environments. Vitamin C helps recycle oxidized antioxidants, sustaining their protective capacity.
Safety and tips
Label Warning: Keep out of reach of children. Do not use if safety seal is damaged or missing. If you are pregnant, nursing, taking any medications, planning any medical procedure, or have a medical condition, consult your healthcare practitioner before use.
Who should be cautious: People sensitive to caffeine-like stimulants may wish to use caution due to green tea extract. Those with bleeding concerns or on blood-thinning medications may use caution with resveratrol and grape-derived extracts. Individuals with allergies to grapes or berries may be cautious due to multiple fruit extracts. Consult a healthcare provider before combining with medications.
