The little-known Japanese breakthrough for circulatory health


Supports normal circulation, blood flow, and blood viscosity
Helps maintain your body’s normal blood-clotting mechanism
Supports natural production of plasmin, which reduces fibrin
Helps maintain normal blood pressure levels.


For over 1,000 years, the Japanese people have been eating natto—a fermented soybean-based food that looks and tastes like soft cheese. Natto contains a specialized enzyme called Nattokinase which was discovered in 1980 by Dr. Hiroyuki Sumi, and has since been the subject of 17 studies, including two small human trials in Japan. Based on this research, Nattokinase is emerging as one of the most promising new nutrients for helping support a healthy circulatory system.

Nattokinase is one of several enzymes related to your circulation. Fibrin, the enzyme that causes blood clotting, is usually broken down by another enzyme, plasmin, which aids normal platelet aggregation and circulation. But plasmin production declines with age. Nattokinase helps by facilitating blood flow the same way plasmin does, and also supports your body's natural production of plasmin.

Our Nattokinase offers only the patented NSK-SD™ formulation, which has its naturally-occurring vitamin K removed. Plus, unlike some others, this product gives you a full 2,000 FU (fibrin units) per day, the dosage recommended by Dr. Sumi and other leading researchers.

Dr. David Williams

Dr. David Williams has a hard-earned reputation as one of the world’s leading authorities on natural healing. Often years ahead of the conventional medical establishment, he has traveled worldwide to locate, evaluate and formulate supplements that work, and write about proven treatments and cures for practically every major health concern today.

Dr. Williams likes to recall that, when he was a kid, people were close and family was important. Since he was raised in a small, hard-working farm community in the Texas panhandle, most people didn't have a lot of the nicer things in life. But they did have something far more important than money; they had values. The people in his community relied on honesty and lived by the Golden Rule—they took care of each other.
Dosage: Take 2 capsules a day, one with morning meal and one at bedtime.
