🚨 High pressure, cold feet and tired all day? A cardiologist explains why they may share the same cause.

Cardiologist Reveals the Hidden Net Behind High Pressure, Cold Feet and Constant Tiredness

"I Take My Pill and the Number Won't Come Down"

I hear it every week:


"Doctor, I take my pill, I cut the salt, and I take my garlic on an empty stomach (ajo en ayunas). And the machine still says 150."


It's not your fault. Only 1 in 3 Latinos who take blood pressure pills have it under control.


There's a cause almost nobody explains.

Three Signs, One Cause

Your pressure won't come down, even when you do everything right.

Cold hands and feet, even in socks.

Tiredness that sleep doesn't fix.

They look like three problems. They're one.

The Cause: A Net in Your Arteries

Over the years, a protein called fibrin forms a sticky net inside your arteries.


Cholesterol gets trapped in it. The artery narrows. Your blood gets thick and slow.


It's like your kitchen drain when it starts to clog.

And that explains all three signs:


Your heart pushes harder. Your pressure goes up.

Blood can't reach your feet well. They stay cold.

Less oxygen gets through. You're always tired.


Before 30, your body cleaned that net on its own. After that, it cleans less every decade.

Why the Usual Things Aren't Enough

Your pill controls the number. It doesn't clean the net. Keep taking it.


Garlic and jamaica help. But they don't break down fibrin.


And store-bought nattokinase? It almost always has less than 2,000 FU. Too little.

What Actually Breaks Down the Net

In Japan, people have eaten natto, a fermented soybean, for more than 1,000 years.


It has a natural enzyme that breaks down fibrin: nattokinase.


In a 12-month study of 1,062 adults, high-potency nattokinase improved their arterial health markers.


But the dose is everything. The research used about 10,000 FU. Below 6,000, no effect was seen.

The Formula I Recommend: Alvena

10,000 FU of clinical-strength nattokinase in one capsule a day.


Plus three helpers:


CoQ10: energy for the heart.
Magnesium glycinate: relaxes the arteries and helps you sleep.
Aged garlic: flexible arteries, without upsetting your stomach.

Taken alongside your pills, never in place of them.

"As a nutritionist, I carefully read every ingredient label... the 10,000 FU is real: my clients are seeing results."

By mid-afternoon my hands and feet felt like ice. Since I started this 10,000 FU formula, my circulation feels noticeably better and I got my energy back. I feel like myself again.

More energy AND better circulation. I can tell the difference: my feet aren't cold anymore and I have steady energy all day.

I've been taking it for a few weeks and so far I have two observations. I walk a lot and I notice less of that annoying leg pain going uphill. The second is that the "morning alarm clock" is back in full force.

Excellent product. I've been taking it for about a month. I can't wait to get my lab results. The subscription is the best option!
