Natural Factors Lung, Bronchial & Sinus Health

About this product

Give your whole respiratory system the support it deserves. This Natural Factors tablet combines NAC and bromelain with traditional herbal extracts — including marshmallow and ivy — to support healthy airways, mucus consistency, and lung tissue.

How it works

N-acetyl-L-cysteine (NAC) supports healthy mucus consistency and helps maintain and nourish already healthy lung tissue. Bromelain, derived from pineapple stem (Ananas comosus), supports normal respiratory function alongside the herbal ingredients. Marshmallow root (Althaea officinalis) and mullein leaf (Verbascum thapsus) are traditional botanicals used to nourish and support the respiratory tract, while wild cherry bark (Prunus serotina) supports healthy respiratory function. Horehound herb (Marrubium vulgare) and ivy leaf (Hedera helix) — the latter standardized to 10% hederacoside C — complement the formula by supporting healthy airways throughout the entire respiratory system.
