Serrapeptase 120,000 SPUs by Lake Avenue Nutrition

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Bronchiectasis. A small clinical study in patients with bronchiectasis shows that taking serrapeptase 30 mg daily for 4 weeks significantly reduces frequency of cough and also seems to decrease sputum viscosity and neutrophil counts in sputum samples when compared with no treatment (13153).
• Chronic bronchitis. A small clinical study in patients with chronic bronchitis shows that taking serrapeptase 30 mg daily for 4 weeks significantly reduces frequency of cough and expectoration and also seems to decrease sputum viscosity and neutrophil counts in sputum samples when compared with no treatment (13153).
• Laryngitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including laryngitis, shows that taking serrapeptase 10 mg three times daily reduces pain, secretions, difficulty swallowing, and body temperature after 3-4 days of treatment when compared with placebo (13152).
• Pharyngitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including pharyngitis, shows that taking serrapeptase 10 mg three times daily reduces pain, secretions, difficulty swallowing, and body temperature after 3-4 days of treatment when compared with placebo (13152).
• Postoperative swelling. Serrapeptase has been evaluated for reducing facial swelling after a variety of procedures. A clinical study in patients undergoing maxillary antrostomy for empyema shows that taking serrapeptase 10 mg orally three times on the day before surgery, once in the evening after surgery, and three times daily for 5 days after surgery modestly reduces buccal swelling when compared with placebo (13151). In patients requiring removal of impacted mandibular third molars, a small clinical study in healthy adults suggests that taking serrapeptase 10 mg three times daily for 5 days improves postoperative trismus and swelling by the fourth postoperative day when compared with placebo; however, no difference in pain scores was observed (106013). The validity of these findings in limited by a lack of consistent comparison to baseline in both groups. Conversely, two other small studies in patients requiring removal of impacted mandibular third molars suggest that serrapeptase is less effective than dexamethasone or another proteolytic enzyme, consisting of trypsin, bromelain, and the flavonoid rutin, for improving swelling or facilitating wound healing (106011,106012). The validity of these findings is limited due to poor study methodologies.
• Rhinosinusitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including rhinosinusitis, shows that taking serrapeptase 10 mg three times daily reduces pain, nasal secretions, nasal obstruction, and anosmia after 3-4 days of treatment when compared with placebo (13152). More evidence is needed to rate serrapeptase for these uses.

POSSIBLY SAFE ...when used orally and appropriately, short-term. Serrapeptase seems to be safe when used in clinical trials lasting up to 4 weeks (13151,13152,13153). There is insufficient reliable information available about the safety of serrapeptase when used long-term.

PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.

General ...Orally, serrapeptase seems to be well-tolerated. Some patients have reported epigastric pain, gastrointestinal upset, and nausea; however, these side effects appear to occur at the same rate as placebo (13152).

Gastrointestinal ...Orally, some patients have reported experiencing epigastric pain, gastrointestinal upset, and nausea; however, these side effects appear to occur at the same rate as placebo (13152).

Immunologic ...There is a case report of bullous pemphigoid, an autoimmune subepidermal dermatosis, in an elderly man who took serrapeptase (13154).
