Vitamin C functions as an antioxidant and cofactor for collagen and carnitine synthesis, and the Ester-C calcium ascorbate form is buffered to be gentler on the stomach.
Caution: High doses may cause digestive discomfort in some people; take with food if sensitive.
Citrus-derived polyphenols may help support antioxidant activity and vitamin C utilization by influencing capillary integrity and free radical balance.
Caution: May cause mild digestive upset in sensitive individuals; avoid if you have known citrus sensitivities.
Calcium supports normal muscle and nerve function and contributes to bone mineralization as an essential electrolyte and structural mineral.
Caution: Total daily calcium from all sources matters; excessive intake may cause constipation or interfere with absorption of some minerals.
Buffered vitamin C provides antioxidant activity and collagen cofactor support while being gentle on the stomach. Citrus bioflavonoids may enhance antioxidant capacity and complement vitamin C’s functions. The calcium from calcium ascorbate contributes a small amount of mineral support without increasing acidity.
Label Warning: If you are pregnant, nursing, taking any medications, or have a medical condition, consult a healthcare practitioner before use. Discontinue use and consult a healthcare practitioner if any adverse reactions occur.
Who should be cautious: People with a history of kidney stones or those limiting calcium or vitamin C intake may consider discussing dosing with a healthcare provider.
