Vitamin C functions as an antioxidant and a cofactor for collagen and carnitine synthesis, and the Ester-C calcium ascorbate form is non-acidic and designed for gentle absorption and cellular retention.
Caution: High intakes may cause digestive discomfort in some people; take with food if sensitive.
Citrus bioflavonoids provide polyphenols that may help stabilize vitamin C and support antioxidant activity in tissues.
Caution: May interact with certain medications due to polyphenol content; separate from medicines if advised.
Acerola supplies naturally occurring vitamin C–related compounds and polyphenols that may complement antioxidant support.
Caution: Contains natural fruit compounds; those sensitive to fruit extracts should monitor tolerance.
Rose hips provide plant polyphenols that may work with vitamin C to support antioxidant defenses.
Caution: May cause mild digestive upset in sensitive individuals; take with food if needed.
Rutin is a flavonoid that may help support capillary integrity and complement vitamin C’s antioxidant actions.
Caution: Those with sensitivity to flavonoids should start with the suggested serving and assess response.
Vitamin C provides core antioxidant and collagen-supporting activity, while the non-acidic Ester-C form aims for gentler absorption and retention. Citrus bioflavonoids, acerola, rose hips, and rutin add plant polyphenols that can stabilize and complement vitamin C’s actions across antioxidant and connective tissue pathways.
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 with a history of kidney stones or high iron absorption may wish to discuss vitamin C intake with a healthcare provider. Those sensitive to citrus or bioflavonoids may consider caution.
