Unlock the power of dual enzyme therapy with Doctor's Best Natto-Serra, expertly formulated to enhance immune function and promote healthy circulation. This innovative blend combines the benefits of serrapeptase and nattokinase, two highly effective proteolytic enzymes, to deliver comprehensive support for your overall health.

Serrapeptase, derived from the friendly bacterium Serratia E-15, is known for its ability to support immune function and reduce inflammation. Doctor's Best uses Serrateric, a superior alternative to enteric coating, ensuring that serrapeptase reaches the intestines for optimal absorption. Nattokinase, sourced from the traditional Japanese fermented soy food Natto, is renowned for its ability to break down blood clotting fibrin, promoting healthy blood flow and cardiovascular health.

Doctor's Best Natto-Serra is gluten-free, non-GMO, and suitable for vegetarians and vegans. For best results, take one capsule daily without food, or as recommended by a nutritionally informed physician. This supplement is not recommended for individuals who are pregnant, lactating, allergic to soy, or have poor digestion. Consult a physician before use if taking blood thinners, and discontinue use if you experience nausea, vomiting, or stomach upset. Store in a cool, dry place.
