About Enzyme Science - Nattokinase Pro

Nattokinase Pro by Enzyme Science delivers nattokinase, a serine protease enzyme derived from fermented soybean (natto), in a concentrated supplement designed to support healthy circulation and normal fibrinolytic activity. It's formulated for adults seeking targeted cardiovascular and blood flow support through enzyme-based intervention.

Why It's Worth Considering: Enzyme Science specializes in enzyme-focused formulations, and this product reflects that focus with attention to enzymatic activity units—a more meaningful measure of potency than weight-based dosing alone.

Who Benefits

Best For

  • Adults seeking nattokinase support for healthy circulation and blood flow
  • Individuals looking to maintain already-normal fibrinogen levels with nattokinase
  • Those supporting cardiovascular wellness through fibrinolytic enzyme activity

Frequently Taken Together

Complete Gut
Probiotics
Enzymes break down food mechanically while probiotics optimize the microbiome. Together they address both aspects of digestion.

Gut Repair
L-Glutamine
Enzymes improve digestion while glutamine repairs the intestinal lining. The two-pronged approach to gut healing.

Stomach Acid
Betaine HCl
Many people have LOW stomach acid (not high). Betaine HCl restores acid while enzymes handle the downstream breakdown.

Frequently Asked Questions

  • Take immediately before or with the first bites of your meal. Enzymes need to be in the stomach when food arrives. Taking them after eating is less effective. For best results, take with every substantial meal — especially meals high in fat, protein, or hard-to-digest foods.

  • They serve different functions. Enzymes physically break down food into absorbable nutrients. Probiotics are living bacteria that optimize the gut microbiome, produce vitamins, and support immune function. Many gut issues benefit from both — especially after age 40 when natural enzyme production declines.

  • No. Digestive enzymes do not cause your body to produce fewer of its own enzymes. They supplement what your body is already making (or under-making). You can stop taking them anytime without withdrawal or rebound. If your symptoms return after stopping, it means you still need the support — not that you've become dependent.
