Description
Enzymedica Natto-K is built around clinically studied NSK-SD nattokinase, but unlike a single-ingredient nattokinase capsule, it is formulated as a comprehensive enzyme blend that also includes bromelain and a full spread of Thera-blend digestive enzymes, alongside calcium and magnesium.
Why NSK-SD nattokinase
Enzymedica notes that NSK-SD is the only form of nattokinase with its own published safety, efficacy and identity data, and is also the only form without vitamin K2, which may interfere with some medications. Nattokinase supports the body's natural circulatory clearing system by helping break down fibrin, a protein found in the blood, which is why it is commonly researched for cardiovascular health and circulation.
What's in each serving
Alongside 1,000 FU of NSK-SD nattokinase blend, each serving includes 96 GDU bromelain, 3,600 DU Amylase Thera-blend, 16,000 HUT Protease Thera-blend, 1,000 CU Cellulase Thera-blend, 40 AGU glucoamylase, 685 FIP Lipase Thera-blend, plus small amounts of calcium and magnesium. This makes it more of a broad enzyme support formula than a nattokinase-only product, which is worth knowing if you specifically want to compare nattokinase strength alone against other products.
The vegetarian HPMC capsule contains just water as an additional ingredient, and the formula is vegan, kosher, gluten-free, soya-free and wheat-free, with no artificial colours, fillers or flavours.
Who this suits
Natto-K suits people who want cardiovascular-focused enzyme support alongside general digestive enzyme coverage, rather than a simple single-ingredient nattokinase capsule. If you are specifically comparing nattokinase products purely by FU strength, it is worth noting the 1,000 FU here sits below the more common 2,000 FU single-ingredient products in our range, since this formula's FU is one part of a wider enzyme blend rather than the sole focus.
Choose your pack size
Natto-K is available in 30 or 90 capsule counts, both taken at the same dose, so the larger bottle simply extends your supply before reordering.
How to use it
Take one capsule three times daily on an empty stomach, one hour before or two hours after a meal. Consult a physician before use if you are pregnant or nursing, taking medications, or have a medical condition.

Storage
Keep out of reach of children and do not use if the safety seal is broken or missing.
