Quercetin acts as a polyphenol antioxidant that may help stabilise mast cells and modulate histamine release while supporting cellular defences against oxidative stress.
Caution: May interact with certain medicines and can cause digestive discomfort in some people; start with food to gauge tolerance.
Vitamin C functions as a water-soluble antioxidant and cofactor for enzymatic reactions involved in collagen formation and immune cell function.
Caution: High intakes may cause digestive upset; the buffered form is gentler on the stomach but take with food if sensitive.
Bromelain is a proteolytic enzyme from pineapple that may influence inflammatory signalling and assist protein breakdown.
Caution: May increase bleeding risk, especially when combined with blood-thinning agents; stop before planned procedures.
Citrus bioflavonoids provide polyphenols that may support capillary integrity and enhance vitamin C’s antioxidant activity.
Caution: May cause mild gastrointestinal discomfort in sensitive individuals; take with meals if needed.
Rutin is a flavonol glycoside that may help strengthen vascular walls and provide antioxidant support.
Caution: Large amounts may cause stomach upset; monitor tolerance.
Quercetin and rutin supply flavonoid antioxidants, while citrus bioflavonoids further reinforce these polyphenol actions. Vitamin C supports immune cell function and collagen formation and may recycle oxidised flavonoids. Bromelain offers enzyme activity that complements flavonoids’ modulatory effects on tissue responses.
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 adverse reactions occur.
Who should be cautious: People with pineapple allergy should be cautious due to bromelain. Those on anticoagulants or with bleeding concerns may wish to discuss quercetin and bromelain use with a healthcare professional.
Storage: Store at room temperature.
