Vitamin C functions as an antioxidant and cofactor for enzymes involved in collagen formation and carnitine synthesis, and calcium ascorbate is a buffered form that may be gentler on the stomach.
Caution: Large doses may cause digestive discomfort; take with food if sensitive.
Citrus bioflavonoids provide polyphenols that may help support antioxidant activity and complement vitamin C’s role in vascular and connective tissue support.
Caution: May cause mild digestive upset in some people; consider taking with food.
Calcium supports normal muscle and nerve function and contributes to bone mineralisation; in this product it also buffers ascorbic acid to a less acidic form.
Caution: Total daily calcium intake from all sources matters; excessive intake may cause constipation in some individuals.
Vitamin C provides core antioxidant and collagen enzyme cofactor roles, while citrus bioflavonoids add complementary polyphenols that may help stabilise and recycle antioxidants. The calcium component buffers the vitamin C to reduce acidity, supporting comfortable digestion.
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 use vitamin C cautiously. Those on calcium-sensitive medications may also wish to check with a healthcare professional. Given the presence of calcium, people taking thyroid medications or certain antibiotics may consider separating dosing. Consult a healthcare provider before combining with medications that may interact.
Storage: Store at room temperature.
