Nattokinase and nitric oxide: the vascular stack, explained
Share
Anyone researching circulation support eventually meets the same two names: nattokinase, the enzyme from fermented soybeans, and nitric oxide, the signaling molecule that tells blood vessels to relax. They get discussed as if they were rivals or a package deal, and they are neither. Here is what each one actually is, how a sensible vascular stack fits together, and the exact doses on record in the LiveWell Earth formulary.
What is nattokinase?
Nattokinase is an enzyme produced during the fermentation of natto, a traditional Japanese food made from soybeans fermented with Bacillus subtilis. Natto has been eaten for centuries, and the enzyme extracted from it has become a popular supplement in its own right. The research area around nattokinase concerns circulatory health, and its activity is usually expressed in fibrinolytic units (FU) rather than plain milligrams, which is worth knowing when reading any nattokinase label.
One honest note before going further: because nattokinase is an enzyme that interacts with the body's clotting machinery, anyone taking prescription medication, and especially anyone whose medication touches clotting, should involve their clinician before adding it. That is not fine print. It is the whole point of respecting mechanisms.
What is nitric oxide and why does it matter for circulation?
Nitric oxide is a gas the body makes on purpose. It is a signaling molecule produced in the lining of blood vessels, and its message is simple: relax, widen, let flow increase. Healthy nitric oxide production supports normal circulation, oxygen delivery, and the vascular flexibility that exercise depends on. Production declines with age, which is why nitric oxide sits at the center of most conversations about supporting circulation naturally.
You cannot swallow nitric oxide. You can only supply the body with its raw materials, and there are two well-known paths to do it.
How do you support nitric oxide production naturally?
The first path runs through L-citrulline, an amino acid the body converts to L-arginine, which is then converted to nitric oxide. Citrulline is often preferred over taking arginine directly because it survives the digestive tract more efficiently. The second path runs through dietary nitrates, the compounds concentrated in beets and leafy greens, which the body reduces step by step into nitric oxide.
The formulary covers both paths, with every dose declared. Veloflow Elixir, a newer entry in the range, carries 2,000 mg of L-citrulline per two-capsule serving, alongside 250 mg of trans-resveratrol, 200 mg of turmeric extract standardized to 95 percent curcuminoids, 200 mg of grape seed extract, 100 mg of Pycnogenol pine bark extract, 120 mcg of vitamin K2 as MK-7, and 10 mg of CoQ10. The polyphenols support vascular integrity while the citrulline supplies the nitric oxide pathway; the current lineup is on the Heart & Circulation collection page.
The nitrate path belongs to Beetroot Powder: single-ingredient organic beet root powder in 10 g stick servings, nothing added and nothing hidden. Dietary nitrates from beets are the most food-like way to feed the second pathway, which is why beetroot has become a fixture in pre-workout and circulation routines alike.
Where do omega-3s fit in the vascular stack?
If nitric oxide support is about flow, omega-3 fatty acids are about the structure that flow moves through. EPA and DHA are incorporated into cell membranes throughout the cardiovascular system, and the research area around them centers on cardiovascular and cognitive function. Omega-3 delivers 180 mg of EPA and 120 mg of DHA per softgel from algae oil, a plant-sourced route to the same fatty acids fish are prized for, with 90 servings per bottle.
Why do the small doses in the formula matter too?
The headline number in Veloflow Elixir is the citrulline, but the quieter lines on the label were chosen deliberately. Vitamin K2 as MK-7, at 120 mcg, belongs to the research area around directing calcium to bone rather than soft tissue, which is why it appears in arterial-support formulas. CoQ10, at 10 mg, supports cellular energy production in tissue that never rests. And the trio of polyphenols, trans-resveratrol at 250 mg, grape seed extract at 200 mg, and Pycnogenol pine bark at 100 mg, represents three distinct plant families whose shared research area is the integrity and flexibility of blood vessels.
The point is not that more lines make a better label. The point is that every line carries a number, so the formula can be judged ingredient by ingredient instead of taken on faith as one combined total.
How does the stack fit together?
| Layer | What it is | What it supports | Dose on record |
|---|---|---|---|
| L-citrulline | Amino acid precursor in Veloflow Elixir | Nitric oxide production, circulation | 2,000 mg per serving |
| Dietary nitrates | Organic Beetroot Powder | The nitrate-to-nitric-oxide pathway, stamina | 10 g stick serving |
| EPA and DHA | Algae-sourced Omega-3 softgels | Cardiovascular and cognitive function | 180 mg EPA · 120 mg DHA per softgel |
| Polyphenols | Resveratrol, grape seed, Pycnogenol in Veloflow | Vascular integrity | 250 mg · 200 mg · 100 mg per serving |
| Nattokinase | Enzyme from fermented natto | The circulatory research area; not currently in the formulary | Sold in FU, not mg, elsewhere |
Can you take nattokinase alongside nitric oxide support?
They work on different levers: one is an enzyme acting on the blood itself, the others supply signaling precursors and structural fats. Mechanistically they are not redundant. Practically, the more levers a stack pulls, the more it deserves a clinician's eyes, especially where prescription medication is involved. The formulary's current position is the nitric oxide pathway first, built from declared doses of citrulline, nitrates, polyphenols, and omega-3s, because those are the inputs whose milligrams can be printed, tested, and verified batch by batch.
The LiveWell Earth standard
Every bottle on the circulation shelf meets the same bar. Every milligram is on the label, from the 2,000 mg of citrulline down to the 120 mcg of K2. Every batch is third-party tested, with the certificate of analysis on record. And every order carries the 30-day guarantee: feel it or free. The dose is the claim.
Frequently asked questions
Is L-citrulline better than L-arginine?
Citrulline is generally the preferred precursor because it passes through digestion more efficiently and is converted to arginine inside the body, sustaining the raw material for nitric oxide production. Arginine taken directly is broken down in the gut to a much larger degree, which is why modern circulation formulas usually lead with citrulline.
What foods support nitric oxide naturally?
Beets, arugula, spinach, and other leafy greens carry dietary nitrates; watermelon is the best-known food source of citrulline. A vegetable-heavy plate is the baseline, and a measured beetroot serving is the most direct way to make the nitrate habit consistent.
When is Veloflow Elixir available?
Veloflow Elixir is part of the range and is being prepared for release. The Heart & Circulation collection always shows the formulas available to order today, alongside the full ingredient records.
How much EPA and DHA should a serving deliver?
The only wrong answer is an undisclosed one. The house Omega-3 declares 180 mg of EPA and 120 mg of DHA per softgel, so a reader can do the math against their own target intake instead of trusting a front-label total that never breaks down.
