The Science Behind It

Nattokinase is an enzyme derived from natto, a traditional Japanese fermented soybean food eaten for centuries. It supports healthy circulation and the body’s normal clotting processes.

Potency is measured in fibrinolytic units (FU) — and it’s where most brands quietly cut corners. Each serving delivers a full 4,000 FU, stated plainly on the label.

Nattokinase works gradually — the most meaningful circulation support typically builds over 2–3 months of consistent daily use.*

How to Take

Take 2 capsules daily, with or without food. Many customers take it in the morning with their other heart-health staples.

Circulation support is a daily practice — the enzyme works while you live your life.

Shipping & Returns

We offer tracked shipping on all orders, processed within 24 business hours on weekdays.

U.S. orders typically arrive in 3–5 days. Shipping is free on subscriptions and on one-time orders over $50.

Returns are easy. Every order is covered by our 90-day money-back guarantee — email help@lumanutrition.com and we’ll handle everything.

Is It Safe?

Yes — our nattokinase is made in FDA-registered, GMP-certified U.S. facilities with no proprietary blends. Every batch is third-party tested for purity and potency by an independent ISO 17025-accredited lab.

Important: because nattokinase supports normal clotting function, talk to your doctor before use if you take blood thinners (like warfarin or daily aspirin), have a bleeding disorder, are scheduled for surgery, or are pregnant or nursing.

Most nattokinase bottles cut the FU dose.

Stop paying for a label that hides its fibrinolytic units.

Under-dosed

Nattokinase potency is measured in FU — fibrinolytic units. Many bottles deliver 2,000 FU or less per serving and hope you never check.

Hidden blends

Proprietary blends let a brand put nattokinase on the label while telling you nothing about how many units are actually inside.

Untested

Many brands claim third-party tested. Can they prove it? Ask them for a result. We post ours freely. Click here.

We built this bottle to a higher standard. Here’s the proof.

Premium quality for a fair price. The Luma 4-Point Verification checks potency, purity, microbiology and identity confirmation on every batch. We publish the results of all third-party testing.

How long until I see results?

Nattokinase builds with consistent daily use, so it steadies rather than hitting all at once. Typical, not guaranteed — which is why the guarantee runs 90 days.

Week 1–2 Feeling the flow

The first thing most people notice: a general lift in energy and stamina through the day.

Week 3–4 Steady support

Daily circulation support settles in as levels build with consistent use.

Week 8+ The checkup window

Cardiovascular markers move slowly. This is the window where checkups tend to show it.

Jake Langley, founder of Luma Nutrition

I couldn’t find a brand I trusted. So I built one.

It started with a supplement I almost bought for my parents. The label looked impressive. But I couldn’t find any test results, and the dose was a fraction of what the research used.

The Army drilled honor and integrity into me. You don’t cut corners when people are counting on you. The supplement industry cut them everywhere I looked.

So I built Luma to a higher standard: meaningful doses, independent testing on every batch, and verified results anyone can see.

Nothing goes in these bottles that I wouldn’t give my family or take myself. We’ll never ask you to trust a claim we aren’t willing to prove.

Questions? Reach out. I read and answer them.

Questions before you order.

How long until I see results?

Most people notice a lift in energy and stamina within the first couple of weeks. Circulation support builds more gradually — give it two to three months of consistent daily use before judging.

How do I take it?

One serving daily, with or without food. The full serving size is printed on the label. Many customers take it in the morning.

What exactly is nattokinase?

An enzyme derived from natto, a traditional Japanese fermented soybean dish. We extract and standardize the enzyme — 4,000 FU per serving — so you get the potency without the taste.

Can I take this with my prescriptions?

Ask your doctor first — especially if you take blood thinners like warfarin or daily aspirin, or have surgery scheduled, since nattokinase supports normal clotting function. Call us before you order and we will talk it through.

How is this different from a cheaper nattokinase?

Most bottles deliver 2,000 FU or less, or hide the number entirely. We deliver a full 4,000 FU per serving, state it on the label, and publish a lab report for every lot.

What if it does not work for me?

You get your money back. The whole order, empty bottles included, for 90 days. No forms and no restocking fee.

Real customers, real results.
