Adults seeking a gentle, high-potency vitamin C option or those with diets low in fruits and vegetables.

Vitamin C functions as an antioxidant and cofactor for collagen and carnitine synthesis, and the Ester-C form provides buffered, non-acidic ascorbate with vitamin C metabolites that may support cellular uptake.
Caution: May cause digestive discomfort in some people; taking with food can improve tolerance.
Citrus bioflavonoids act as polyphenol antioxidants that may help stabilize vitamin C and support healthy capillary integrity.
Caution: May interact with certain medications due to polyphenol content; separate from medications if sensitivity occurs.
Calcium serves as an essential mineral for muscle contraction, nerve signaling, and bone mineralization, and buffering with ascorbate reduces acidity of vitamin C.
Caution: High calcium intake from multiple sources may contribute to constipation in some individuals.
Buffered vitamin C supplies non-acidic ascorbate for antioxidant and connective tissue support, while naturally occurring vitamin C metabolites may aid cellular utilization. Citrus bioflavonoids provide complementary antioxidant activity and support capillary function, and the included calcium helps buffer acidity for gentler digestion.
Label Warning: If you are pregnant, nursing, taking any medications, or have a medical condition, consult a healthcare practitioner before use. Stop use and consult a healthcare practitioner if any adverse reactions occur.
Who should be cautious: People prone to kidney stones may need caution with high-dose vitamin C. Those on anticoagulants may wish to monitor due to added vitamin C and bioflavonoids. People with iron overload conditions may need caution since vitamin C may affect iron absorption. Consult a healthcare provider if combining with medications.
Storage: Store at room temperature.
