Immune support, antioxidant support, collagen formation, upper respiratory wellness
Adults seeking a gentle, high-strength vitamin C option for daily antioxidant and immune support, including those who prefer a once-daily capsule.
Adults take 1 capsule once daily, preferably with a meal; taking with food may improve tolerance for vitamin C.

Vitamin C functions as an antioxidant and a cofactor for enzymes involved in collagen formation and carnitine synthesis, and supports normal immune cell activity.
Caution: May cause digestive discomfort in some people; taking with food can help tolerance.
Citrus flavonoids act as antioxidant polyphenols that may help stabilise vitamin C and support normal capillary integrity.
Caution: May interact with certain medications; separate dosing from new medications until tolerance is known.
Calcium contributes to normal muscle and nerve function and acts as a mineral cofactor in cellular signalling.
Caution: Moderate calcium intake from supplements is usually well tolerated; avoid taking at the exact same time as iron to minimise absorption competition.
Vitamin C provides the primary antioxidant and immune-related support, while citrus bioflavonoids offer additional polyphenols that may help protect vitamin C and vascular tissues. The buffered calcium ascorbate form supplies calcium and reduces acidity, making vitamin C gentler on the stomach.
Label Warning: If you are pregnant, nursing, taking any medications, or have any 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 use vitamin C cautiously. Those on calcium-sensitive medications may consider spacing doses. Discuss with a healthcare provider if unsure about interactions.
Storage: Store at room temperature.
