Natural Factors Lung, Bronchial & Sinus Health is a tablet formula combining modern nutraceutical ingredients with traditional herbal extracts to support the entire respiratory system — from the nasal passages and sinuses through the bronchi to the lung tissue itself.
The formula includes N-acetyl-L-cysteine (NAC), an amino acid derivative, and bromelain, a proteolytic enzyme sourced from the stem of the pineapple plant (Ananas comosus). The herbal component features marshmallow root (Althaea officinalis), provided as a 4:1 extract; mullein leaf (Verbascum thapsus), as a 4:1 extract; and wild cherry bark (Prunus serotina), also as a 4:1 extract. Horehound herb (Marrubium vulgare) and ivy leaf (Hedera helix) round out the herbal complex, with ivy extract standardized to deliver hederacoside C at 10%.
This combination is described by Natural Factors as a unique blend of both contemporary nutraceutical and age-old herbal support, formulated to nourish and support the entire respiratory system. The product is suitable for adults and is available in tablet form in 45- and 90-count sizes.
