Doctor’s Best – Serrapeptase – 120,000 SPU – 270 capsules
Availability
This product is currently no longer available. Due to changes in availability and distribution, this dietary supplement has been removed from the European assortment.
As an alternative, we recommend taking a look at Serretia® by Arthur Andrew Medical, a product within the same product segment.
Serrapeptase is an enzyme of natural origin. It belongs to the group of proteolytic enzymes, meaning enzymes that are involved in the breakdown of protein structures. Serrapeptase was first isolated in the 1960s by Japanese researchers from a non-pathogenic bacterial strain (Serratia).
In dietary supplements, serrapeptase is used in a pure, standardized form and encapsulated in capsules designed for absorption in the digestive tract.

What is serrapeptase?
Serrapeptase is an enzyme of natural origin. It belongs to the group of proteolytic enzymes, meaning enzymes that are involved in the breakdown of protein structures. Serrapeptase was first isolated in the 1960s by Japanese researchers from a non-pathogenic bacterial strain (Serratia).

General background on mucous membranes and mucus
Mucous membranes line various hollow structures of the body that are in contact with the external environment, such as the nose and airways. These membranes produce mucus, a viscous substance that helps to moisten and protect these surfaces.
Within normal physiology, mucus plays a role in trapping inhaled particles and supporting the natural cleansing mechanisms of the airways. The composition and structure of mucus are important for comfort and proper function.
Serrapeptase as an enzyme
Proteolytic enzymes such as serrapeptase are studied for their ability to influence protein structures. Scientific literature describes that serrapeptase can interact with protein components in mucus, which is associated with changes in its physical properties. These findings are purely descriptive research observations within the context of normal bodily functions.
Research and use
Serrapeptase has been studied for a considerable time in various research contexts, particularly in Japan and Europe. These studies have examined parameters such as mucus structure and general physiological processes. The available literature describes the use of serrapeptase as a dietary supplement within these research settings.
Enzyme activity (SPU)
The quality and strength of enzymes are not determined by weight, but by activity. For serrapeptase, this activity is expressed in Serratiopeptidase Units (SPU), which indicate the amount of enzymatic activity present per capsule.
Dietary supplements are available with different activity levels, for example 40,000 SPU or 120,000 SPU per capsule. These values indicate enzymatic activity only and do not imply any medical effect.
General information
This product is a dietary supplement and not a medicinal product. Dietary supplements are intended to complement a varied, balanced diet and a healthy lifestyle. The described properties are based on general scientific literature on enzymes and do not constitute medical claims.
