Sinus health, nasal comfort, immune support
Adults seeking enzyme-based support for seasonal sinus comfort or those who prefer a once-daily, vegan, non-GMO option.
Adults take 1 capsule daily on an empty stomach with at least 8 oz of water; taking away from meals helps preserve enzyme activity. New users may start with a lower-strength serrapeptase product per the label guidance.
Non-GMO; Vegan
Serrapeptase is a proteolytic enzyme that breaks down specific protein substrates, which may help reduce accumulation of unwanted protein debris in tissues and secretions.
Caution: Take on an empty stomach because food proteins can reduce enzyme activity; avoid use if pregnant, nursing, on blood-thinning medications, or if you have digestive discomfort, as enzymes may increase bleeding risk and can cause gastrointestinal upset in some people.
Calcium serves as a mineral that supports cellular signaling and structure, with a small amount included here as part of the protective Serrateric coating system.
Caution: This is a low amount for most adults, but consider total daily calcium intake if combining multiple supplements to avoid excessive intake.
Serrapeptase provides targeted proteolytic activity, while the Serrateric protective system helps the enzyme reach the intestines for better absorption and activity away from stomach acid.
Label Warning: Not recommended if you are pregnant, lactating, taking anticoagulants, or have poor digestion. Stop use if you experience nausea, vomiting, or stomach upset.
Who should be cautious: People with bleeding concerns or scheduled surgery, digestive sensitivity, or allergies to enzyme-based products may need extra caution. If you use anticoagulants, discuss with a healthcare provider before use.
