Nattokinase 10,800 FU - Enteric Coated

Most nattokinase never makes it past your stomach. Here’s why that matters.

Nattokinase is a fibrinolytic enzyme from fermented soybeans, traditionally used in Japan to support cardiovascular and circulatory health. But enzymes are fragile. Stomach acid breaks them down before they can enter the bloodstream, where research shows they actually do their work. Take nattokinase with food or in a standard capsule, and most of the enzyme may be destroyed before it ever reaches the small intestine.

The dose only matters if the delivery works. The landmark 2022 cardiovascular study used 10,800 FU per day for 12 months. But nearly every 10,800 FU product on the market sits in a standard capsule with no protection against stomach acid.

Therexa Nattokinase 10,800 FU is enteric-coated, engineered to resist stomach acid and release the enzyme in the small intestine where it can be absorbed. One clean ingredient, one capsule coating built to protect what you’re paying for. †

Therexa CoA Nattokinase Analysis

Benefits

  Exactly the Dose the Study Used: 540 mg of nattokinase standardized to 10,800 FU per serving—the precise daily amount used in the landmark 12-month cardiovascular study. † 

  Enteric Coating That Protects the Enzyme: Standard capsules dissolve on contact with stomach acid, where most of the nattokinase breaks down before it can reach circulation. Our enteric-coated capsules are designed to survive the stomach and release the enzyme in the small intestine, where it can be absorbed and support systemic fibrinolytic activity. † 

  Heart & Circulatory Support: Nattokinase supports healthy fibrinolytic activity—the body’s natural process for maintaining normal blood flow and circulation. Traditional Japanese cardiovascular wisdom, standardized into a single daily serving. † 

  120 Capsules, 60-day Supply: Real value, so you can stay consistent long enough for the full study-length duration to matter.

LAB TEST RESULTS FOR EVERY PRODUCT cGMP CERTIFIED FACILITY USA LAB-TESTED  90-DAY MONEY-BACK GUARANTEE OPTIMAL ABSORPTION

Every Batch. Tested. Published.

We send every Therexa product to independent, accredited laboratories in the United States for third-party testing. Then we publish the results — not summaries, not badges, the actual reports.

Heavy Metals (Every Batch)

Every batch is screened for arsenic, cadmium, lead, and mercury to ensure safety.

Microbial Contamination (Every Batch)

Every batch is tested for bacteria, yeast, mold, E. coli, Salmonella, and other pathogens.

Identity Verification (Annual)

Each product undergoes annual identity testing to confirm the ingredients match exactly what's on the label.

Why This Matters?

  • The supplement industry is largely self-regulated. Many brands never test their products - or only test once and reuse that report for years.
  • We test every batch for safety. We verify every product annually for identity. And we will show you the results.
  • If a brand won't publish their lab reports, ask yourself what they're hiding.
