Premium-potency NSK-SD nattokinase — sourced through our partnership with Micro Ingredients — for daily circulatory and cardiovascular wellness support.*
187 health-conscious customers recommend Wildroot Nattokinase Complex.
High-potency nattokinase capsule
Take one capsule daily with water, ideally on an empty stomach.
Nattokinase is an enzyme originally isolated from natto, a traditional fermented soybean food. Wildroot's capsules are enteric-coated so more of the active enzyme survives digestion intact, supporting the body's natural circulatory processes as part of a daily wellness routine.
No powders to mix, no aftertaste, no complicated dosing.
Most people take Wildroot as part of a consistent daily wellness routine, alongside a healthy diet and regular movement.
Rather than a one-time fix, Wildroot is designed for ongoing, everyday support — one small capsule that fits into a morning routine without any prep.
What you can expect is a simple, science-backed addition to your routine, sourced from a trusted enzyme supplier and third-party tested for potency.
Try Wildroot with confidence. If you’re not satisfied, you’re covered by our Lifetime Money-Back Guarantee — return your order at any time and we’ll issue a full refund according to our refund policy. No deadlines, no questions.
A note on safety: nattokinase can affect blood clotting. Consult your physician before use, especially if you take blood thinners or have a bleeding disorder.
A high-potency nattokinase complex trusted by people building a daily circulatory wellness routine.

Not all nattokinase is created equal. Here’s what goes into every batch of Wildroot, sourced through our partnership with Micro Ingredients.
Nattokinase is an enzyme originally isolated from natto, a fermented soybean food eaten in Japan for centuries. We source ours from a controlled fermentation process, not a synthetic substitute.
Potency is measured in Fibrinolytic Units (FU). Wildroot is standardized to 2,000 FU per serving, so every capsule delivers a consistent, verified dose.
The coating is designed to help the enzyme pass through stomach acid intact, so more of it reaches the small intestine where it can be absorbed.
We use the NSK-SD strain of nattokinase, a widely studied grade of the enzyme used in nattokinase research and supplementation.
Every batch is tested by an independent lab for potency and purity before it ships, so you know what's on the label is what's in the capsule.
Our merger with Micro Ingredients gives Wildroot access to larger-scale sourcing and manufacturing standards — without changing the formula you count on.
Every time someone asks “does this actually work?” under our ads, the answers come from people already taking it.
Does this actually work?? I've tried a couple nattokinase brands before and honestly couldn't tell a difference. Skeptical of anything with a big markup.
Karen Delmar it's the potency that matters, not just the label. bought it in April after checking the FU count and it's noticeably higher than what I was taking before
Rita McAllen ok update — 3 weeks in and it's been an easy add to my morning routine, no stomach upset at all 😂 thank you!!
somebody tell me how a soybean enzyme is supposed to do anything for circulation because i don’t buy it. taken plenty of supplements that did nothing
Greg Paulsen it’s the FU count that matters. nattokinase is legit studied, and this one is enteric-coated so it actually survives digestion. my doctor buddy put me onto checking for that two years ago and I haven’t looked back
Dale Whitcomb alright, i ordered the 3-pack and have been taking it for two weeks. easy to work into my routine so far. wife’s starting on it monday
Healthy circulation isn’t automatic — a handful of everyday habits and life stages can work against it. Here’s what to know.*
