Supportive Socks Only Work While Worn: 6 Reasons to Add BloodFlow-7® XXXL

Whether you wrestle a supportive sock over your heel every morning or spend the day sitting at a desk, your legs can feel lighter. A sock works on the outside of the leg. BloodFlow-7® XXXL works on the inside, on the blood vessels themselves, with four clinically studied ingredients at the doses the research actually used. Keep the socks. Add the part they cannot reach.

01

It Works From the Inside.

A sock presses on the outside of the leg. XXXL works on the vessels inside it.

Your legs and feet depend on blood to bring them oxygen and nutrients, and they sit at the far end of the trip. Stand all day or sit all day and that trip gets harder. Supportive socks help by applying steady pressure from the outside. What they cannot change is how freely the vessels open from within.

The key is nitric oxide. It signals your blood vessels to relax and widen, helping support healthy blood flow all the way down to your feet. That is the part BloodFlow-7® XXXL is built for, and it is why it sits alongside your socks rather than replacing them.

02

It Reaches What a Sock Cannot.

A sock squeezes the leg. Nitrosigine® works in the blood moving through it.

Pressure from the outside can help move blood along, but it cannot add anything to the blood itself. That part has to come from the inside.

Nitrosigine® is an enhanced arginine engineered to stay in circulation rather than break down early, giving your body a steady supply of the raw material it uses to make nitric oxide. Standard BloodFlow-7® carries 500 mg. XXXL carries 1,500 mg, the full dose used in the published research, so the support reaches every part of the leg the blood reaches, including the parts a sock never touches.

03

It Supplies the Raw Material and Protects It.

Green coffee beans, green tea, turmeric, blueberries, cherries, broccoli and kale

One ingredient hands your body the building block. Another keeps it from breaking down.

Nitrosigine® gives your body the building block for nitric oxide. S7® works on the other side. It is a blend of seven plant extracts, clinically shown to raise the body's own nitric oxide by up to 230% at a 50 mg dose. It supplies no arginine and no nitrates. Its polyphenols reduce the oxidative stress that breaks nitric oxide apart before your body can use it, so more of what you already produce stays in play.

Most products pick one pathway. XXXL runs both, in the same capsule.

04

It Supports the Vessels Themselves.

Pressure from outside can only do so much. Relaxed, flexible vessels do the rest.

Trans-Resveratrol has been shown to improve arterial dilation by up to 62%. That is vessel relaxation across the whole system, from the heart all the way down to the ankles.

BioPerine® is the fourth ingredient. It does one job, which is to help the other three absorb. A formula that reads well on the label and does not absorb is not doing your legs any good, and XXXL was built so every ingredient gets where it needs to go.

05

One Capsule Routine. Nothing to Pull On.

Pulling a supportive sock over the heel is a wrestling match. This is a glass of water.

Take XXXL as directed on the label with a glass of water, then carry on with your morning. Keep wearing your socks if they help. XXXL does not ask you to change anything. There is no powder to mix, no loading phase and no caffeine, so it works around your day instead of the other way round.

Every ingredient and every dose is printed on the panel, with nothing hidden inside a proprietary blend.

Why XXXL?

Supportive socks apply pressure from the outside of the leg. BloodFlow-7® XXXL works from the inside, supporting the nitric oxide that signals your blood vessels to relax and widen, and it keeps working after the socks come off.

XXXL carries 1,500 mg of Nitrosigine®, the full amount used in the published research, alongside S7®, Trans-Resveratrol and BioPerine®. It is Juvenon's maximum-strength formula, and it is designed to complement your socks, not replace them.

What's Inside
  • Nitrosigine® (1,500 mg) An enhanced arginine built to stay in circulation rather than break down early. It keeps arginine elevated in the blood for up to six hours per dose.
  • S7® A blend of seven plant extracts, clinically shown to raise the body’s own nitric oxide by up to 230% at a 50 mg dose. It supplies no arginine and no nitrates. Its polyphenols reduce the oxidative stress that breaks nitric oxide apart before your body can use it.
  • Trans-Resveratrol Shown to improve arterial dilation by up to 62%. That is vessel relaxation across the whole system, not a training effect.
  • BioPerine® Black pepper extract with one job, which is helping the other three absorb.

No caffeine and no stimulants. Every ingredient and every amount is printed on the supplement panel, with nothing hidden inside a proprietary blend.

Science and Quality

The formula is built on nitric oxide signalling, the discovery recognised with the 1998 Nobel Prize in Medicine. Nitric oxide is the signal that tells your blood vessels to relax and widen so blood moves freely to every organ and cell.

Juvenon has been formulating in this category for more than two decades. BloodFlow-7® XXXL was developed by Dr. Luke Bucci, PhD, Juvenon’s Chief Science Officer, a biomedical scientist and clinical nutritionist, and built to Juvenon’s Beyond Substantiation standard. It is manufactured in the United States in an FDA-registered, cGMP-certified facility.

Directions

Take as directed on the label with a glass of water. Many people take it in the morning, around the time their socks go on, whether the day ahead is on their feet or at a desk.

There is no powder to mix, no loading phase and no timing ritual, and because there is no caffeine it can be taken at any hour. It works best as a daily habit, since circulation support builds with consistent use. If you take prescription medication, speak with your doctor before adding any supplement.

Subscription and Shipping

Subscriptions ship automatically on the schedule you choose and include free shipping on every order. You can pause, reschedule or cancel any time from your account, with no fees and no minimum number of orders.

One-time orders ship free over $75. Everything dispatches from our United States facility, and tracking lands in your inbox as soon as your order is on its way.

Guarantee

Try BloodFlow-7® XXXL for 60 days. If it is not doing what you hoped, contact our team within 60 days of delivery and we will refund your purchase. No forms to chase and no hoops.

Sixty days is long enough to judge it on how you feel rather than on how it reads on a label.

Every dose of Nitro XXXL is backed by science to help athletes, professionals, and anyone looking to optimize their performance feel the difference — quickly, safely, and effectively."

Extreme Energy

2 times the boost in energy, and I love that all the products have natural ingredients, and not harmful ingredients that don't work.

Living well.

With Juvenon, my blood pressure remains under control. My Dr. is pleased and I feel great. When I first started taking it, I lost 20 pounds without even trying. My skin looks younger.

At one point, I thought I was doing so good that I stopped taking it for 2 months. My blood pressure shot back up. The weight came back and my skin was sagging. I started taking it again about 2 months ago. The weight fell right off, my blood pressure is under control and I feel great. It’s all about the flow.

Open up and clean up

Opens up for the blood flow. 60 yrs old male trying everything and this works. I started out using the regular product and moved to XXXL and taking 3 in morning and 3 at night for 2 weeks and you’ll notice difference, then I reduced to 2 each time and alternating 3 in here and there but product works great after a couple of weeks. Be patient, it works. In fact I just gave a half a bottle to a friend and he’s noticing a difference also and he’s 62.
