3Enzymedica
Enzymedica - MucoStop, For Relief of Sinus Congestion and Excess Mucus, 48 Capsules
Main highlights- WHY ARE YOU SUFFERING?: There are many variables that can cause excess mucus and hinder upper and lower respiratory function. Among these are cold temperatures, changes in season, allergic reactions and medications. Encouraging removal of excess mucus may lessen the discomforts commonly associated with seasonal or occasional congestion.
- TARGETED ENZYME SUPPORT: Enzymes are highly specific in terms of what they act upon and what they do. Proteolytic enzymes break down proteins. But not all proteases can break down all proteins. For example, a protease that effectively digests food protein will not be effective at breaking down mucus protein. To break down mucus, an enzyme that is classified as both proteolytic and mucolytic is required.
- CLEAR RELIEF: MucoStop contains a blend of enzymes specifically formulated to naturally promote easy breathing during seasonal or occasional congestion. Mucolase is a high-potency proteolytic enzyme that targets and hydrolyzes excess mucus. Mucolase also assists the body?s natural ability to break down and eliminate excess mucus in the sinus and nasal passages. Protease and amylase are also included to assist in overcoming the challenges often associated with seasonal or occasional congestion.
