Optimize Your Blood Flow: Source Naturals Nattokinase (4,000 FU & 8,000 FU)
Think of your circulatory vessels like household plumbing pipes. Over time, microscopic web-like protein debris called fibrin can accumulate in the bloodstream, slowing natural fluid flow and increasing vascular drag.Nattokinase acts like a precision biological drain sweeper. Derived from traditional Japanese fermented soy (natto), this systemic enzyme actively cleaves excess fibrin mesh to maintain normal blood viscosity, arterial elasticity, and healthy circulation throughout your entire body.

Why Source Naturals NSK-SD® Beats Bargain Brands
- Guaranteed Active Potency: Commodity retail supplements often use crude, unstandardized natto powders with unverified enzymatic activity. Source Naturals verifies genuine Fibrinolytic Units (FU) via HPLC testing so stomach acid does not deactivate the enzyme before absorption.
- Vitamin K2-Free: Whole natto beans naturally contain Vitamin K2, which promotes blood clotting and works against the fibrin-clearing actions of nattokinase. Patented NSK-SD® extracts the active enzyme while completely removing Vitamin K2.
- Clean & Pure: 100% vegetarian capsules tested for heavy metals down to parts-per-billion via ICP-MS, free of gluten, dairy, wheat, and synthetic additives.
Quick Biochemical Usage Rule
Always take nattokinase on an empty stomach with 8 oz of water—ideally at bedtime.If taken with food, the enzyme acts like a digestive aid and breaks down meal proteins instead of entering your vascular system. Nighttime dosing ensures peak systemic enzyme activity when circulation naturally slows during sleep.
(Caution: Consult your physician prior to use if taking prescription blood thinners such as warfarin or aspirin, or if scheduled for surgery within 14 days.)
