NAC serves as a precursor to glutathione and can help thin mucus by breaking disulfide bonds in mucin proteins.
Caution: May cause gastrointestinal discomfort; use with food if sensitive.
Bromelain is a proteolytic enzyme that may help break down mucus proteins and support a normal inflammatory response in airways.
Caution: May increase bleeding risk, especially with blood-thinning supplements or medications.
Marshmallow root contains soothing polysaccharides that form a protective film on mucous membranes of the throat and airways.
Caution: May reduce absorption of medications if taken at the same time due to its mucilage content.
Mullein leaf provides polyphenols and saponins that may promote healthy mucus clearance and comfort in the respiratory tract.
Caution: Rare digestive upset is possible; discontinue if sensitivity occurs.
Hederacoside C–rich ivy extract contains saponins that may support bronchiole smooth muscle relaxation and mucus transport.
Caution: May cause mild gastrointestinal effects in some individuals; take with water and avoid on an empty stomach if sensitive.
NAC and bromelain focus on mucus breakdown from different angles—NAC by reducing mucus viscosity and bromelain by enzymatic protein cleavage. Marshmallow and mullein provide soothing compounds that coat irritated tissues while supporting mucus clearance. Ivy extract adds saponins that may promote airway comfort and ciliary transport for easier breathing.
Label Warning: Consult a health professional before use if you are pregnant, breastfeeding, or trying to conceive, or if you take medication, have a medical condition, or anticipate surgery.
Who should be cautious: People with pineapple allergy should be cautious due to bromelain. Those with gastrointestinal sensitivity may react to N-acetyl-L-cysteine. If you use blood thinners or have bleeding concerns, bromelain may increase bleeding risk; discuss with a healthcare provider before use.
Storage: Store in a cool, dry place.
