Vitamin C functions as an antioxidant and cofactor for collagen and carnitine synthesis, and Ester-C’s metabolites may support uptake and retention in white blood cells.
Caution: May cause mild digestive discomfort in some people; take with food if sensitive.
Calcium is an essential mineral that contributes to cellular signaling and bone mineralization.
Caution: Monitor total daily calcium intake from all sources to avoid excessive amounts.
Vitamin C in Ester-C form offers buffered, non-acidic ascorbate with metabolites that may improve retention, while the accompanying calcium helps buffer acidity, making the formula gentler on the stomach.
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 you experience adverse reactions.
Who should be cautious: People who are sensitive to vitamin C or calcium, or who have a history of kidney stones, may want to discuss use with a healthcare provider. Those monitoring calcium intake may also wish to review the calcium content with a clinician.
Storage: Store at room temperature.
