Vitamin C acts as a water-soluble antioxidant and enzyme cofactor, supporting collagen synthesis, carnitine and neurotransmitter production, and helping recycle other antioxidants.
Caution: High intakes may cause digestive discomfort in some people; take with food to improve tolerance.
Quercetin is a polyphenol that may help modulate oxidative stress by scavenging free radicals and influencing antioxidant enzymes.
Caution: May interact with certain medications due to effects on metabolizing enzymes; consider spacing from medicines.
Galactomannans are soluble fibers that can influence absorption characteristics and may support gentle digestive function.
Caution: Fenugreek-derived fibers may cause mild gas or bloating in sensitive individuals.
Vitamin C provides direct antioxidant activity and serves as a cofactor for collagen formation, while quercetin adds complementary polyphenol antioxidant activity. The bio-quercetin matrix with galactomannans is designed to enhance quercetin’s absorption, helping it work alongside vitamin C’s actions.
Label Warning: Do not exceed the recommended dose. Do not use if the outer seal is broken or damaged. Consult a physician if you are being treated for a medical condition or if you are pregnant or lactating.
Who should be cautious: People with citrus sensitivity or quercetin sensitivity may consider caution. If you have kidney stones, high iron levels, or are on prescription medications, discuss use with a healthcare provider before use.
