Nattokinase Supplements

What nattokinase is

Nattokinase is an enzyme extracted from natto — soybeans fermented with a specific culture, eaten in Japan for centuries. As a supplement, it’s concentrated into capsules and is one of the enzymes people most often look into as part of a heart- and circulation-focused routine.

Understanding FU (fibrinolytic units)

Nattokinase potency is measured in FU, not just milligrams — so FU is the number to compare between products. A common strength is 2000 FU per capsule, with higher-potency options at 4000 FU. Checking the FU per serving is the clearest way to compare two nattokinase supplements.

Forms we carry

• Capsules — the standard format; simple and pre-dosed.
• Delayed-release capsules — designed to release the enzyme further along in digestion.
• Higher-potency (4000 FU) — a stronger dose per capsule for those who want it.
• NSK-SD — a well-known branded, standardized nattokinase you’ll see named on several labels.
• Combination formulas — some pair nattokinase with ingredients like garlic for a broader heart-health formula.

How to choose

Start with the FU potency that suits you, then the format — standard or delayed-release. If you’re comparing, FU per serving matters more than the milligram weight. Combination formulas suit people who want nattokinase alongside other heart-health ingredients.

An important safety note

Nattokinase affects how your blood behaves, so this one genuinely matters: if you take blood thinners or other medications that affect clotting, are pregnant, have a bleeding condition, or are scheduled for surgery, talk to your doctor or pharmacist before taking nattokinase. Don’t stop or replace any prescribed medication with it.
