Vitamin C functions as an antioxidant and cofactor for collagen and carnitine enzymes, and Ester-C’s metabolites may support uptake and retention in white blood cells.
Caution: May cause digestive discomfort in some people; taking with food can help tolerance.
Bioflavonoids may help support antioxidant activity and vascular integrity by interacting with reactive oxygen species and supporting capillary function.
Caution: May interact with certain medications; separate from new supplements and review with a healthcare professional if on prescriptions.
Calcium contributes to cellular signaling and bone mineralization while serving as the mineral counterion for the Ester-C form of vitamin C.
Caution: Total daily calcium from all sources adds up; consider overall intake to avoid excessive amounts.
Vitamin C provides core antioxidant and collagen cofactor roles, while bioflavonoids add complementary antioxidant and capillary support; the Ester-C form includes metabolites that may aid cellular uptake and retention. Calcium acts as the mineral carrier for ascorbate and contributes to daily calcium intake.
Label Warning: If you are pregnant, nursing, taking any medications, or have a medical condition, consult a doctor before use. Stop use and consult a doctor if any adverse reactions occur.
Who should be cautious: People with kidney concerns or a history of kidney stones may want to be cautious with high-dose vitamin C. Those limiting calcium intake should note the added calcium. If you take medications, discuss with a healthcare provider before use.
Storage: Store at room temperature.
