Caution: May increase bleeding tendency when combined with anticoagulants due to its enzyme activity; stop if unusual bruising occurs.
Vitamin C functions as an antioxidant and a cofactor for enzymes involved in collagen formation, which may support healthy mucosal barriers.
Caution: High intakes can cause stomach upset in some people; take with food if sensitive.
Zinc is a cofactor for numerous enzymes and supports epithelial integrity and normal immune cell function.
Caution: Avoid taking at the same time as high‑calcium or high‑iron supplements, which can reduce zinc absorption.
