Ascorbate acts as an antioxidant that donates electrons to help neutralise free radicals and supports collagen formation and normal immune function.
Caution: May cause digestive discomfort in sensitive individuals; taking with food can improve tolerance.
Magnesium functions as a cofactor for many enzymes involved in energy metabolism, muscle and nerve function, and electrolyte balance.
Caution: High intakes may loosen stools; divide doses and take with food if sensitive.
Bioflavonoids are plant polyphenols that may help stabilise vitamin C and support antioxidant activity in tissues.
Caution: May interact with certain medications due to polyphenol content; separate from medicines if unsure.
Vitamin C provides antioxidant activity and collagen support, while magnesium contributes to enzyme function and helps buffer acidity for gentler tolerance. Citrus bioflavonoids complement vitamin C by supporting its stability and antioxidant actions.
Label Warning: If you are pregnant, may become pregnant, or breastfeeding, consult a healthcare professional before use.
Who should be cautious: People with kidney concerns or those prone to kidney stones may wish to discuss higher-dose vitamin C and magnesium intake with a healthcare professional. Those with a history of diarrhoea or sensitive digestion may start with a lower amount to assess tolerance.
