Source Naturals NSK-SD Nattokinase, Systemic Enzyme for Healthy Circulation* 100mg - 60 Vegan Capsules

I was skeptical of these pills when my brother in law recommended them. I have been taking them daily for months just as directed on the bottle. (Empty stomach,lots of water) and my cholesterol levels have been steadily dropping! Of course I’ve made other changes and it’s not just a magic pill but I do believe that these have helped a lot! There’s no after taste and the capsule is very small and easy to swallow.

I bought this for my husband who has a bit of calcium build-up in a major arterial valve. He is hoping this helps decrease or slow future build-up. He took this for the entire bottle. It did not upset his stomach in any way. I will purchase more for his daily use.

Great product for the circulatory system.

Good product and value if it does what it's supposed to?

Easy to swallow capsule, no after-taste. Seems to work well has, I believe, to slow my tachycardia somewhat after a month's usage with no stomach upset.

Watch on You tube: Nattokinase We Tested Them All. This one actually contains what it says it does. Others that look quality, aren't.

Excellent product—repeat customer!

I will never underestimate my body’s need for proper enzymes. Good for my heart, good for my circulation, good for my well-being. Nattokinase capsules, because, I don’t really like the taste of natto.
