## Doctor's Best High Potency Serrapeptase — 120,000 SPU | 90 Vegan Capsules
**Science-Based Nutrition™** — Doctor's Best High Potency Serrapeptase is a professional dietary supplement with a proteolytic enzyme, providing **120,000 SPU (serratiopeptidase units)** in one delayed-release capsule. Thanks to advanced **Serrateric™** coating technology, the product is designed to bypass stomach acid and release the enzyme directly in the intestines — where it works most effectively.
### What is Serrapeptase?
Serrapeptase is a proteolytic (protein-digesting) enzyme derived from the bacterium *Serratia sp.* It has been widely used in Europe and Asia for decades. It has the ability to break down unwanted proteins that accumulate in the body. Doctor's Best offers this enzyme in a high dose, providing real support for daily well-being.
### Key Benefits
- **Supports sinus health** — helps maintain sinus patency by breaking down excess proteins that form mucus
- **Breaks down unwanted proteins** — proteolytic action targeting proteins that may accumulate in the body
- **Supports nasal health and immune function** — helpful for seasonal sinus discomfort year-round
- **Delayed-release technology (Serrateric™)** — ensures the enzyme reaches the intestines intact, maximizing bioavailability
### Advanced Delivery System: Serrateric™
Unlike standard enteric coating processes, Serrateric™ is a patented blend developed with Maltodextrin, Tricalcium Phosphate, Calcium Stearate, Microcrystalline Cellulose, and Medium Chain Triglycerides. This system protects the enzyme from degradation in the acidic stomach environment and releases it in the intestines, where absorption is optimized.
