Approved Science Nattokinase - 4000 FU (200 mg) - with BioPerine - Vegan, Non-GM - 180 Capsules

Key Benefits of Nattokinase Supplementation

If you're looking to support your heart and circulation naturally, this enzyme may help. Nattokinase is best known for its role in promoting healthy circulation. By aiding the breakdown of fibrin — a protein involved in clotting — this enzyme supports optimal blood flow and helps maintain healthy cardiovascular function. It is a popular choice for those seeking a non-drug approach to circulatory health, especially for individuals concerned with blood viscosity or occasional leg discomfort. This supplement offers a natural botanical alternative without relying on pharmaceutical interventions.

What Is Nattokinase and Why Is It Used?

Nattokinase is a potent enzyme extracted from natto, a traditional Japanese soybean dish. It has become popular for its ability to support healthy blood flow and maintain cardiovascular wellness. Approved Science Nattokinase delivers 4,000 fibrin units (FU) per serving — a concentration commonly used in clinical research. Each capsule provides 200 mg of pure nattokinase, formulated without vitamin K2 to minimise interactions for those on certain medications. Its origins in fermented soya make it a unique and natural choice for supplementation.

How to Choose a Quality Nattokinase Supplement

Approved Science Nattokinase is standardised to 4,000 FU per serving — a clinically relevant dose. It also contains BioPerine® (black pepper extract) to enhance absorption, ensuring your body gets the full benefit of each capsule. The product is manufactured in the USA in a cGMP-certified facility and undergoes rigorous third-party testing for purity and potency. Plus, it is vegan, non-GM, gluten-free, and dairy-free — suitable for most dietary needs.

FAQs About Nattokinase

How should I take Nattokinase?

The recommended serving is typically 2 capsules per day, taken with water on an empty stomach for best absorption. Always follow the label instructions.

Can Nattokinase be taken with other supplements?

Nattokinase is generally safe to combine with other supplements, but because it affects blood flow, avoid taking it with high-dose vitamin K2 or other blood-thinning supplements without professional guidance.

Are there any side effects?

Most people tolerate nattokinase well. Mild digestive upset may occur initially. If you have a bleeding disorder or are scheduled for surgery, discontinue uses two weeks before and consult your doctor.
