Product Details

Navitol is built on Dr. Martin's miracle nutrient: an extract from the bark of a pine tree that holds more than 40 nutrients. It is one of the most powerful antioxidants in nature, roughly 50 times stronger than vitamin C.

60 capsules per bottle. A 60-day supply at 1 capsule a day. Doctor-formulated. Water soluble, so your body does not store it up.

Benefits

Supports healthy blood flow head to toe, steady all-day energy, a clearer head, and comfortable circulation in the legs and hands. A powerful antioxidant that also helps the body make nitric oxide, which tells your blood vessels to relax and open up.

How To Take

Most people take 1 or 2 capsules a day. If you feel really run down, Dr. Martin has people start with 4 to 6 a day for the first month, then drop back to 1 or 2. Take it any time, with food or without. You cannot take too much: Navitol is water soluble.

Supplement Facts

Pine bark extract standardized for antioxidant content. See the Supplement Facts image in the gallery for the full panel. Doctor-formulated by Dr. Martin.

60-Day Money-Back Guarantee

Try it for 60 days. If you do not feel the difference, we will make it right. The risk is on us, not you.

When did you get so tired?

You did not use to be like this. There was a time you popped out of bed with drive. Here is what is really going on, and the one thing that brings you back.

142,256+ customers trust Dr. Martin Used in clinic since 1911

Now you wake up already tired. You need the coffee just to feel human.

By two in the afternoon, you hit a wall. Your body gets heavy. Your eyes want to close. And there is still so much day left.

Then there is the fog. You walk into a room and forget why. You lose your words in the middle of a sentence.

This is not you. This is not the person you have been your whole life.

Here is the good news. That person is not gone. They are still in there. They are just not getting what they need.

It comes down to one thing. Blood flow.

Your blood is your life. It carries oxygen. It carries energy. It carries everything your body needs to work. And it goes everywhere: your brain, your heart, your eyes, your legs. Every inch of you.

So think about what happens when your blood does not flow like it should. The parts that do not get enough blood start to struggle:

  • Your brain gets foggy
  • Your legs get heavy and tired
  • Your energy drops through the afternoon
  • You feel old before your time

It is not that you are broken. Those parts of you are just starving. Navitol helps your blood flow. That is the whole secret. When the blood comes back, so does everything else.

Dr. Martin

Blood cells flowing freely through a healthy vessel.

Why Navitol Reaches Where Others Cannot

There is a wall inside you called the blood-brain barrier. It protects your brain and keeps most things out. Very few things in nature can get past it.

  • 1It brings blood flow head to toe. From your legs to your feet to your fingers, Navitol helps your blood get where it has a hard time reaching.
  • 2It reaches your brain. The active ingredient in Navitol can cross the blood-brain barrier, bringing fresh blood flow right to where the fog lives.
  • 3It fights the slow rusting of age. As a powerful antioxidant, it fights the wear that happens to all of us as the years go by.

More blood. More oxygen. More you.

Navitol Ultra Strength

The story of Rosie

Rosie is Dr. Martin's wife. And for years, she was sick. She was tired all the time. She hurt all over. Some days she could barely get out of bed.

So she did what you are supposed to do. She went to the doctors. It took years just to get an answer. Chronic fatigue. Fibromyalgia. But a diagnosis is not help. It is just a name. A specialist told her, "Come back and see us in 10 years."

Dr. Martin stopped waiting on them and went looking himself. That is when he found it: a nutrient he would later call his miracle nutrient. He gave it to Rosie. And she started to come back. Her energy returned. The fog lifted. The pain let go. She has her life back.

  • ✓ Navitol was Dr. Martin's very first product
  • ✓ Hundreds of thousands of people have taken it since
  • ✓ Doctor-formulated. Used in clinic since 1911.

Dr. Martin's miracle nutrient was not new. It is very old. It comes from the bark of a pine tree.

Almost 500 years ago, the explorer Jacques Cartier and his crew were frozen in the ice and dying of scurvy. A local indigenous man showed them how to make a tea from pine bark. They drank it. And they lived.

Nature made it a long time ago. Dr. Martin put it in a bottle.

What's Inside

One nutrient, doing a lot of work. Every capsule is built around the pine bark extract Dr. Martin calls his miracle nutrient.

Pine bark extract
Pine Bark ExtractUltra Strength

The bark of a pine tree holds more than 40 nutrients. It is one of the most powerful things in nature, and the whole reason Navitol exists. It is what brings the blood flow back.

A powerful antioxidant, roughly 50 times stronger than vitamin C. It fights the slow rusting of age that happens to all of us as the years go by.

Blood vessel relaxing and opening
Nitric Oxide SupportBlood flow

Navitol helps your body make nitric oxide. It is what tells your blood vessels to relax and open up. When they open up, your blood flows free, head to toe.

Doctor-formulated by Dr. Martin. Water soluble, so your body does not store it up and it does not go through your liver like some things do. It is gentle. Navitol is not meant to diagnose, treat, cure, or prevent any disease.

People say it is just getting older. That is not it.

You know it in your gut. This is not how it has to be.

Waiting It Out

You wonder if this is just how it is going to be now. You wait, and the tired and the fog and the heavy legs slowly become your normal. Rosie was told to come back in 10 years.

Getting The Blood Flowing

Rosie did not wait. She got her life back. When the blood comes back, the oxygen comes back, the energy comes back, your brain lights up, and your legs feel lighter.

Talk to your doctor before you start, especially if you take medicine or have a health problem.

What to Expect

Blood flow does not come back overnight. Give it time, and let it build day by day, the way it did for Rosie.

1

The First Weeks

Many people notice steadier energy and a bit less afternoon crash as the blood starts moving better.

2

Around Month 1

The fog begins to lift. People find their words come easier and the head feels clearer.

3

Month 2 And On

Heavy legs feel lighter, energy holds through the day, and you start to feel like yourself again.

Try it for a full 60 days. If you do not feel the difference, we will make it right.

How Much Should I Take?

We pack a lot into every capsule, so a little goes a long way.

Two capsules in an open palm

One Or Two A Day

That is your normal dose. One bottle of 60 capsules is a 60-day supply at 1 a day.

A daily pill organizer with a glass of water

Run Down? Start Higher

Dr. Martin has people start with 4 to 6 a day for the first month, then drop back to 1 or 2.

A woman taking her daily capsule with morning coffee

Any Time, Gentle

Morning or night, with food or without. Navitol is water soluble, so you cannot take too much.
