Description
Vitacost Nattokinase NSK-SD is an enzyme extracted from natto, the traditional Japanese dish made from boiled and fermented soybeans. What sets this product apart is that it is made using a patented process that removes all vitamin K2, giving a highly purified NSK-SD form manufactured from non-GMO soybeans.
Why the vitamin K2 removal matters
Many people specifically look for nattokinase without vitamin K2, often because they are also taking vitamin K supplements separately or want to manage their vitamin K intake independently of their nattokinase dose. NSK-SD is a specific, standardised nattokinase ingredient used across a number of brands, and Vitacost's version is processed to strip out the K2 that can otherwise be present in natto-derived extracts.
What's in each capsule
Each capsule provides 100 mg nattokinase standardised to 2,000 FU. Other ingredients are microcrystalline cellulose, gelatin, vegetable stearic acid and vegetable magnesium stearate. Because the capsule uses gelatin, this product is not suitable for vegetarians or vegans. If you would prefer a plant-based capsule at the same 2,000 FU strength, our Natural Factors Nattokinase, 100 mg is a vegetarian option.
Who this suits
This product suits people who have specifically been comparing nattokinase supplements and want to avoid added vitamin K2, whether because they manage their vitamin K intake separately or simply prefer a nattokinase-only formula. It is a simple, single-ingredient supplement rather than a multi-ingredient blend, which makes it easy to compare against other 2,000 FU nattokinase products on strength and price.
How to use it
As a dietary supplement, take one capsule daily on an empty stomach, or as directed by a healthcare professional. Each 90-capsule bottle provides 90 servings, a three-month supply at this dose. Keep the capsules dry and at room temperature, between 15 and 24 degrees Celsius.
Who should be cautious
Pregnant or lactating women, people with diabetes, hypoglycemics, and people with known medical conditions including blood coagulation disorders should consult a licensed physician or pharmacist before taking this product, as should anyone taking anticoagulant drugs such as warfarin or heparin, or supplements containing vitamin K. Do not exceed the recommended daily dose.
