Vitamin C functions as an antioxidant and enzyme cofactor, supporting collagen formation and aiding immune cell function while the Ester-C form is designed to be gentler on the stomach.
Caution: High intakes may cause digestive discomfort; take with food if sensitive.
Citrus bioflavonoids act as polyphenolic antioxidants that may help protect vitamin C from oxidation and support its utilisation in tissues.
Caution: May interact with certain medications sensitive to flavonoids; consider spacing doses if unsure.
Calcium contributes to normal muscle and nerve function and serves as the mineral component bound to ascorbate in this non-acidic vitamin C form.
Caution: Total daily calcium from all sources matters; excessive intake may cause constipation in some people.
Vitamin C provides the primary antioxidant and collagen-supporting activity, while citrus bioflavonoids help stabilise and utilise vitamin C in the body. Calcium bound to ascorbate buffers acidity, making the formula gentler for sensitive stomachs.
Label Warning: If you are pregnant, nursing, taking any medications, or have any medical condition, consult your doctor before use. Stop use and speak to your doctor if any adverse reactions occur.
Who should be cautious: People who need to limit calcium intake or who have a history of kidney stones may wish to discuss use with a healthcare provider due to vitamin C and calcium content.
