NAC also protects the respiratory system against illness and infection while decreasing the frequency of chronic bronchitis as well as the severity of flare-up symptoms. NAC may also offer anti-viral benefits, as well as promote clear airways and alleviate chest congestion through its mucolytic activity.

Zinc Citrate

Take 1 capsule per day with food

Supports immune health, including the reduction of cold and flu symptoms, duration, and severity. Also promotes healthy skin, eyes, male fertility, and prostate health. 

Each capsule contains 30 mg of zinc in the highly bioavailable citrate form. Zinc is a mineral essential for immune health, clinically shown to decrease the duration of common cold symptoms. Zinc also plays a key role in blood sugar management, prostate health, and male fertility. Zinc may slow the progression of eye-related conditions such as macular degeneration. Zinc is especially useful for those following a vegetarian or vegan diet, as dietary sources of zinc include red meat and shellfish.
