How the Longevity Essentials Stack
Works in Your Body
From capsule to circulation, bones, and arteries — here's exactly what happens when you take 20,000 FU nattokinase, 120,000 SPU serrapeptase, and CardioBone™ K2 + D3 every day.
Take Your Daily Stack
Take the enzymes on an empty stomach — 30 minutes before a meal or 2 hours after — so they don't compete with food proteins. Take CardioBone™ with a meal, since D3 is fat-soluble and absorbs best alongside food.
Absorbed Into Bloodstream
Nattokinase and serrapeptase survive digestion and pass through the intestinal wall into your bloodstream, circulating systemically — while D3 and MK-7 K2 are absorbed with dietary fat and enter circulation ready to manage calcium.
Triple-Action Begins
Nattokinase supports the body's natural fibrin-regulation processes — the protein behind thick, sluggish blood. Serrapeptase supports the natural inflammatory response throughout tissue. And MK-7 activates osteocalcin and Matrix GLA Protein — directing calcium into bones and away from artery walls.
Whole-Body Longevity Restored
With circulation supported, calcium properly directed, and inflammatory response balanced, the body works as it should. Blood flows freely, bone density strengthens, arteries stay flexible — and most users report more energy, mental clarity, and mobility within weeks.
Three Nutrients Nature Perfected
Long Before Science Caught Up
One enzyme comes from a 1,000-year-old Japanese breakfast food. Another comes from a silkworm dissolving its own cocoon. The third is the vitamin pair that decides whether calcium builds your bones — or hardens your arteries. Together, they're the Longevity Essentials Stack.
The Food That Changed Cardiovascular Science
For over 1,000 years, Japanese people have eaten natto — fermented soybeans — as a daily breakfast staple. Researchers noticed striking patterns: regions with the highest natto consumption had dramatically lower rates of stroke and arterial disease, well into people's 80s and 90s.
In 1980, Dr. Hiroyuki Sumi tested 173 foods for their effect on blood clots. Natto extract dissolved a fibrin clot completely in 18 hours — every other substance took 2+ days or didn't work at all. He named the enzyme nattokinase.
The Enzyme That Frees the Silkworm
A silk cocoon is one of the toughest natural protein structures on earth, with tensile strength comparable to steel. The silkworm has no teeth or tools to escape it — only an enzyme produced by bacteria in its intestine that dissolves the cocoon wall with extraordinary precision.
In the late 1960s, Japanese researchers isolated this bacteria — Serratia sp. E-15 — and found its enzyme could break down non-living protein structures while leaving healthy living tissue completely undamaged. The same mechanism, now called serrapeptase.
The Vitamin Pair That Decides Where Calcium Goes
Vitamin K was discovered in 1929 by Danish researcher Henrik Dam — work that earned a Nobel Prize in 1943. Decades later, science identified what it actually does with calcium: MK-7 activates osteocalcin and Matrix GLA Protein, the two proteins that lock calcium into bone and pull it back out of artery walls.
And there's a remarkable coincidence: natto is the richest dietary source of MK-7 on earth — the same fermented soybean that gave the world nattokinase. Paired with 5,000 IU of Vitamin D3, which drives calcium absorption in the first place, it completes the loop that D3 alone leaves open.
Three Origins, One Daily Stack
None of these are practical to get from food. A serving of natto provides only 1,000–2,000 FU of nattokinase — you'd need 10 servings daily to hit a meaningful dose. No one is eating silkworm cocoons. And most adults get a fraction of the D3 and K2 their bones and arteries need.
AzureVitamins combines all three into a single daily stack: 20,000 FU of nattokinase for circulatory support, 120,000 SPU of serrapeptase for systemic support, and 180 mcg MK-7 with 5,000 IU D3 to direct calcium into bones and away from arteries — the doses used in published research, in clean capsules a day.
The world's highest concentration of people who live past 100. Natto and fermented soy are daily staples — supplying both nattokinase and MK-7 vitamin K2 — and cardiovascular disease is nearly absent.
Three Origins. One Modern Stack.
The Longevity Essentials Stack delivers 20,000 FU of nattokinase, 120,000 SPU of serrapeptase, and 180 mcg MK-7 K2 with 5,000 IU D3 — the same nutrients that have supported circulatory, skeletal, and systemic health in Japan for decades, concentrated into clean capsules. No fillers. No fermented smell. Just the doses used in published research, wherever in the world you live.
6 Reasons Customers Choose the Longevity Essentials Stack
Triple-Action Formula
Nattokinase supports the body's natural fibrin-regulation processes for healthy circulation, Serrapeptase supports natural protein breakdown and inflammatory response, and MK-7 K2 directs calcium into bones — three mechanisms working together to support whole-body function.
20,000 FU + 120,000 SPU + 180 mcg MK-7 — Clinical Strength Throughout
Most stacks deliver low-potency doses of each ingredient. We deliver 20,000 FU of Nattokinase, 120,000 Serratiopeptidase Units of Serrapeptase, and 180 mcg MK-7 with 5,000 IU D3 per day — the full research-referenced amount of all three in one simple daily routine.
Precision at Every Level
Nattokinase targets excess fibrin buildup in the bloodstream, Serrapeptase selectively targets non-living protein structures — the same mechanism that frees the silkworm from its cocoon — and MK-7 activates the proteins that pull calcium out of artery walls and lock it into bone.
Premium Natural Sourcing
Nattokinase from fermented Japanese natto, Serrapeptase from Serratia E-15 — the strain originally isolated from silkworm intestine in the 1960s — and MK-7, the longest-acting, most bioavailable form of K2. All produced by controlled pharmaceutical-grade fermentation. No silkworms. No animal by-products.
Optimised for Absorption
Both enzymes are vulnerable to stomach acid — our capsule shells protect them through the stomach and into the small intestine, where they enter the bloodstream intact. Take the enzymes on an empty stomach; take CardioBone™ with a meal, since D3 is fat-soluble and absorbs best alongside food.
Clean, Minimal Formulas
Nattokinase 500mg (20,000 FU), Serrapeptase 60mg (120,000 SPU), Vitamin K2 MK-7 180 mcg with Vitamin D3 5,000 IU, plus Microcrystalline Cellulose and Silicon Dioxide. No unnecessary fillers, no hidden blends. Third-party tested for identity, potency, and purity.
What Our Customers Are Saying
Real results from real people — verified purchases only.
"My doctor was genuinely surprised"
Been taking this for 8 weeks. My last checkup showed my readings moved into a healthier range dropped from 138/88 to 122/78. My doctor asked what I changed. I told him — just added AzureVitamins Nattokinase. The 20,000 FU potency is no joke. Other brands I tried at 2,000 FU did nothing. This one actually works.
"Finally — a potency that actually does something"
I've tried nattokinase from 3 other brands. All of them were between 2,000–4,000 FU and I felt nothing. Switched to AzureVitamins 20,000 FU and within 3 weeks my legs stopped feeling heavy and swollen by the end of the day. Clean formula, no fillers. I'm not going back.
"Noticeable difference after 4 weeks"
Takes a little patience — don't expect overnight miracles. But around week 4 I noticed I was waking up with more energy and my morning pressure readings were consistently lower. High potency was a big selling point for me. Most supplements are loaded with junk.
"Circulation in my hands and feet improved"
I've had cold hands and feet for years. My cardiologist recommended nattokinase but said to find a high-potency brand. This is the highest I found at 20,000 FU. After 6 weeks my extremities are noticeably warmer and my energy is better throughout the day. Incredible product.
"More energy, sharper focus, better sleep"
Didn't expect the mental clarity side effect but here we are. Better blood flow = better brain function I guess. Also sleeping deeper than I have in years. I'm 58 and feel like I'm in my 40s again. On my third bottle now. The Buy 3 Get 2 deal made it a no-brainer to stock up.
"Cleanest nattokinase formula I've found"
As a nutritionist I read every ingredient label carefully. Most nattokinase supplements have 10+ ingredients padding. AzureVitamins has minimal added excipients. Plus the 20,000 FU is the real deal — my clients are getting results.
Most Longevity Stacks
Are Only Half the Formula
At 2,000–10,800 FU and 20,000–40,000 SPU — with D3 sold alone and no K2 in sight — standard brands fall below the threshold needed for meaningful results. AzureVitamins delivers 20,000 FU + 120,000 SPU + 180 mcg MK-7 & 5,000 IU D3 — potency that actually moves the needle.
The bottom line: AzureVitamins is the only stack that delivers clinical-strength nattokinase, serrapeptase, and MK-7 K2 with D3 together — addressing circulation, systemic wellness, bone density and arterial health at the same time, in clean formulas, at better value as a stack, backed by a 365-day guarantee.
