Serrapeptase 120,000 SU

High Potency, Enteric Coated Systemic Proteolytic Enzyme

Serrapeptase (serratiopeptidase) is a serine protease originally isolated from bacteria in the digestive tract of the Japanese silkworm, where it breaks down proteins to help the silkworm emerge from its cocoon. Unlike digestive enzymes that act only in the gut, serrapeptase is absorbed intact and works systemically. This formula delivers 120,000 SU per capsule, at the high potency end of the category, in a vegan enteric coated capsule built for intestinal release.

How It Works

A Systemic, Not Digestive, Enzyme

Serrapeptase cleaves peptide bonds in proteins, breaking them into smaller peptides and amino acids. Because it is absorbed from the intestine into circulation, its proteolytic activity extends beyond digestion to tissues and fluids throughout the body.

Fibrinolytic and Mucolytic Activity

Two properties account for most of the research interest in serrapeptase: its fibrinolytic activity, breaking down fibrin, the structural protein behind clotting and scar tissue, and its mucolytic activity, reducing the viscosity of mucus secretions. Both stem from the same broad proteolytic mechanism acting on different protein substrates.

Why Enteric Coating Is Non Negotiable

The Stomach Acid Problem

Serrapeptase is a protein and is denatured by stomach acid (pH 1.5–3.5) before it can reach the intestine. Without protection, the enzyme is inactivated long before it does anything useful.

Vegan Ethyl Cellulose Coating

This formula uses ethyl cellulose, a plant derived, phthalate free polymer that resists dissolving in stomach acid but breaks down in the more neutral pH of the small intestine. That timing is what allows the enzyme to reach the intestine intact and enzymatically active, unlike uncoated serrapeptase or coatings made with animal derived shellac.

Understanding Potency: SU, Not Just Milligrams

SU (Serrapeptidase Units) measures enzyme activity under standardized conditions, the meaningful measure of potency for any enzyme. Two products at the same milligram weight can differ widely in SU depending on enzyme quality. Common serrapeptase supplements range from 40,000 to 120,000 SU per capsule; this formula sits at 120,000 SU from 60 mg of serrapeptase per capsule.

Clinical Research

Serratiopeptidase: A Systematic Review of the Existing Evidence

International Journal of Surgery, 2013

This systematic review evaluated 24 studies. The authors found limitations including small samples and methodological weaknesses, and concluded that evidence was insufficient to support serratiopeptidase as an analgesic or health supplement. They also noted a lack of long-term safety data. The review concerns serratiopeptidase generally, not this specific product.

Role of Serratiopeptidase After Surgical Removal of Impacted Molar: A Systematic Review and Meta analysis

Journal of Maxillofacial and Oral Surgery, 2018

This review included five studies of serratiopeptidase after impacted-molar surgery. Compared with corticosteroids, it found improvement in trismus, but no significant difference in swelling. The authors noted that the limited number of studies prevented firm conclusions about other outcomes and comparisons. These findings apply to post surgical dental care, not general supplement use.

Treatments for Breast Engorgement During Lactation

Cochrane Database of Systematic Reviews, 2020

This Cochrane review included one trial of serrapeptase versus placebo involving 59 women. It found low-certainty evidence that serrapeptase may reduce breast engorgement, while its effects on breast pain and swelling remained uncertain. The findings are specific to lactation-related breast engorgement and do not establish benefits for general supplement use.

Frequently Asked Questions

What is Serrapeptase used for?

Serrapeptase is commonly used as an enzyme supplement in formulas focused on tissue, inflammatory response, and general wellness support, although evidence for many systemic uses remains limited.

What does 120,000 SU mean?

SU stands for Serratiopeptidase Units, a measure of serrapeptase enzyme activity. Enzyme supplements are better compared by activity units than by milligram weight alone.

What is a proteolytic enzyme?

A proteolytic enzyme is an enzyme that helps break proteins into smaller peptides and amino acids. Serrapeptase belongs to this group of enzymes.

Why is Serrapeptase enteric coated?

An enteric coating is designed to resist breakdown in the acidic environment of the stomach and release the enzyme later in the digestive tract.

Why is enzyme activity measured in SU instead of milligrams?

Milligrams indicate the physical weight of an ingredient, while SU measures enzymatic activity. Two serrapeptase products with the same milligram amount can potentially have different activity levels.

Can Serrapeptase be taken with blood thinners?

People taking anticoagulant or antiplatelet medications should consult a healthcare professional before using serrapeptase because of potential effects on bleeding risk.
