Ingredients explained
Bromelain (20 GDU/serving)
Bromelain provides proteolytic enzymes that may help break down protein-based byproducts and support a balanced inflammatory response in tissues.
Caution: May increase bleeding risk when combined with blood-thinning drugs because proteolytic enzymes can affect clotting; take with food if you have a sensitive stomach.
Vitamin C (ascorbate)
Vitamin C functions as an antioxidant and a cofactor for collagen and catecholamine synthesis, which may support epithelial integrity and normal immune activity.
Caution: High doses can cause digestive discomfort; those with a history of kidney stones should be mindful of total vitamin C intake.
Zinc (ascorbate)
Zinc is a cofactor for many enzymes and helps support normal immune cell function and antioxidant defenses.
Caution: Taking zinc on an empty stomach may cause nausea; long-term high intake can affect copper balance.
Olive leaf extract (within SinusClear Herbal Blend)
Olive leaf polyphenols like oleuropein have antioxidant activity and are studied for supporting a balanced microbial environment.
Caution: May interact with blood pressure medications because of potential vasodilatory effects.
Stinging Nettle leaf (within SinusClear Herbal Blend)
Stinging nettle leaf contains polyphenols that may support a normal inflammatory response in nasal passages.
Caution: May have mild diuretic effects, so hydrate adequately and monitor if using other diuretics.
How they work together
Proteolytic enzymes from bromelain work on protein debris while vitamin C and zinc support immune cell function and antioxidant status. Olive leaf and nettle contribute plant polyphenols that complement these actions by supporting a balanced microbial environment and a calm inflammatory response in nasal tissues.
Safety and tips
Label Warning: Consult a doctor before use if pregnant, nursing, taking medication, have a medical condition, or have difficulty swallowing. Proposition 65 warning: exposure to lead, a chemical known in California to be associated with cancer and reproductive harm.
Who should be cautious: People with allergies to pineapple or bromelain-sensitive individuals may be cautious due to bromelain. Those with ragweed or related plant sensitivities may be cautious with herbs like stinging nettle. If you take blood thinners or have bleeding concerns, bromelain may increase bleeding risk, so discuss with a healthcare provider before use.
