Nattokinase, 90 vege caps, Doctor's Best

Doctor's Best Nattokinase — 2,000 FU (fibrinolytic units) of Nattokinase enzyme per capsule, derived from fermented non-GMO soybeans using traditional Japanese natto fermentation. Vitamin K2 removed. Supports healthy blood flow, circulation, and cardiovascular health. Vegetarian. 90 veggie caps.

Why you need it

Nattokinase is a powerful enzyme derived from natto — a traditional Japanese fermented soybean food with over 2,000 years of use for cardiovascular health. During the fermentation process, friendly Bacillus subtilis bacteria produce nattokinase, an enzyme that supports the body’s natural blood-clotting control mechanisms and helps maintain healthy blood flow and circulation. Think of it as supporting your blood’s own housekeeping system — helping to keep things flowing smoothly and efficiently. Nattokinase has attracted significant research interest for its ability to support healthy circulation, particularly for people with sedentary lifestyles, those who travel frequently on long flights, or anyone interested in maintaining cardiovascular health. Doctor’s Best uses a high-quality nattokinase extract with Vitamin K2 removed — making it suitable for those on anticoagulant medications who need to avoid K2 (though physician consultation is still essential if you take blood thinners). Each capsule delivers a meaningful 2,000 FU of enzyme activity — the standard therapeutic dose used in research.
