3 Serious Warfarin Side Effects Long-Term

Warfarin side effects can be serious. You want to make sure you don't get a stroke, so that's why you take this blood thinner medication -- to prevent a stroke, right?

Well, here's the bad news:

  1. People using warfarin have an increased chance of getting bleeding brain strokes. Strokes due to bleeding are among dangerous coumadin side effects, say researchers.

As you get older, dangerous coumadin side effects such as strokes due to bleeding, are much more likely! So if you plan on living a long time, you should know that after the age of 80, the chances of your getting a bleeding brain stoke SKYROCKETS when taking warfarin!

But there is more...

2. The long term effects of warfarin? A build-up of calcium in the arteries.

These long term effects of Coumadin, including aortic valve stenosis, may not be what you are bargaining for.  Why?

Calcium build up in the arteries -- one of the long term effects of warfarin -- is THE leading cause of hardening of the arteries and of heart disease. 

3. Alzheimers and dementia have now also been added to the list of warfarin side effects long term.  This is even more likely if you are using warfarin as an AFIB treatment.

Consider, if you are in effect being asked to chose between having a stroke and Alzheimers due to these long term effects of warfarin!

Fortunately, there are SAFE supplements that can be taken with or instead of warfarin, against these side effects of warfarin long term use:

Could This Save Your Life?

Fortunately, there's new pieces of the puzzle that can save your life.

You may want to choose one of these two options:

  • You can use natural blood thinners that keep your arteries unclogged and flexible and can dissolve clots before they cause trouble.
  • Or, if you are already taking a blood thinner medication, you can take supplements that can counteract or reverse the dangerous warfarin side effects of Coumadin.

Here's what to do and why:

First, you need to know the difference between vitamin K1 and life-saving vitamin K2.

Why? OK. Your doctor or pharmacist have given you a Coumadin food list and a warfarin vitamin K1 diet for a good reason...

  • The idea behind a warfarin diet is to keep down your levels of vitamin K1 – the clotting vitamin –- to prevent unwanted blood clots. "Thinner" blood with less vitamin K1 takes longer to clot.

This is a GOOD THING. But this requires a DELICATE BALANCE!

The down side is, that instead of clotting, you risk bleeding because you have TOO LITTLE vitamin K1, because there is nothing to stop unwanted bleeding.

And this bleeding can also cause a stroke! Does that mean that Coumadin can cause strokes?

Yes, because the side effects of warfarin can be unwanted bleeding, including brain bleeding, leading to a stroke.

Not exactly what you might have bargained for!

That’s why they want you on a warfarin vitamin k diet – to keep vitamin K1 at a steady level – not too much and not too little -- but this is very tricky -- a little like walking a tightrope!

But there’s one more problem with this blood thinner medication:

Warfarin Side Effects: Aortic Valve Stenosis?

People who take the blood-thinning drug warfarin, eventually tend to get “aortic stenosis”, or the calcification and narrowing (stenosis) of their aortic valve, say researchers.

This is the valve that carries oxygen rich blood from the heart, which becomes rigid, so this will increase your risk of a heart attack.

Aortic valve stenosis is eventually fatal.

What will your doctor recommend for these long term effects of warfarin?

Eventually, the aortic valve will need to be replaced by surgery.

  • But for older people, such surgery is risky, so that instead, they tend to get prescribed very high doses of anti cholesterol drugs such as Crestor.

These high doses tend to have crippling side effects.

What Cleared Sam's Arteries?

Sam needed surgery for aortic stenosis.

Fortunately he successfully avoided this surgery after taking his cardiologist’s advice to take supplements of both vitamin K2 (100 mcg MK-7) and a therapeutic Vitamin D Dosage.

This turned out to be an effective treatment. What happened?

  • Within 10 months, an echocardiogram showed that his aortic valve had opened again, and was a normal, healthy size. No more surgery needed!

(normal = one and a half inches, squared – 3 cm squared, and Sam’s had been half that size of 1.6 cm.)

Fortunately, not to be confused with Vitamin K1 -- Vitamin K2 -- has been found effective for removing calcium from the aorta (aortic valve stenosis) and also helps prevent eventual calcium build-up in the kidneys.

  • To avoid the warfarin side effects of aortic stenosis, you can read the book, THE CALCIUM PARADOX, about how Sam got his aortic valve back to normal WITHOUT SURGERY.
  • You can SAFELY add Vitamin K2 to your diet, because it does not interfere with the blood clotting Vitamin K1.

Vitamin K2 and the Calcium Paradox: How a Little-Known Vitamin Could Save Your Life 

Could Vitamin K2 Save YOUR Life?

Turns out that this little-known vitamin, vitamin K2, is responsible for making sure the calcium in your diet gets to the right place – your bones, rather than collecting in your arteries!

Research is showing that Vitamin K2 PREVENTS calcium from building up in the arteries.

How did they find this out?

Dutch researchers found that people who ate the most cheese, lived on average 7 YEARS LONGER than people who ate the least amount of cheese on a daily basis.

What was the magic ingredient? The Dutch Gouda cheese is high in vitamin K2. This single ingredient accounted for a HUGE difference in lifespan, according to researchers at Leiden University who conducted the Rotterdam study.

Researchers are now looking into how vitamin K2 PREVENTS heart disease by preventing the build-up of calcium in the arteries.

Why? The build-up of calcium PLAQUE in the arteries along with fatty tissues and scar tissue = atherosclerosis, or HARDENING OF THE ARTERIES.

The discovery of the role of Vitamin K2 is being called the Calcium Paradox. Why?

Doctors have known that calcium-containing arterial plaque narrows the blood vessels to the heart.

What doctors have NOT known, is the role of Vitamin K2 in getting calcium OUT OF THE ARTERIES and into the bones, where it is needed.

Here's the Big Surprise about Heart Disease!

Here's the surprise:

  • Because our meat and butter tend not to be from grass fed cows and eggs not from free range chickens anymore, and we’ve been switching to margarine, we have been eating less and less Vitamin K2 to prevent heart disease!

Research is converging to show us that it is a lack of vitamin K2 that’s the SINGLE BIGGEST DIETARY FACTOR OF CARDIOVASCULAR DISEASE RISK!

  • Not cholesterol, not saturated fats, not salt?

No! Researchers are now honing in on Vitamin K2 as the strongest inhibitor of tissue calcification that we know of, and not getting enough of this vitamin, is one of the biggest factors leading to heart disease.

Why? Vitamin K2 regulates calcium metabolism!

Vitamin K2 activates proteins that directs where it gets deposited -– either for storage in your bones, where it belongs, and NOT where it causes trouble -- in your arteries, your kidneys, or even in your skin to cause unwanted wrinkles!

If all is working properly, it turns out that Vitamin K2 activates proteins that prevent calcium from depositing in blood vessels and other tissues e.g. the skin.

Yes, calcium mistakenly deposited in the skin is even a cause of facial wrinkles!

Healthy arteries that are free of plaque, according to researchers, contain proteins that have to be activated by vitamin K2!

Unfortunately we have been told to avoid eating fats and cheeses to prevent heart disease. Remember, Dutch people who ate the most Gouda cheese lived 7 years longer than those who ate the least.

Have we been “shooting ourselves in the foot?” by not getting enough vitamin K2 in our diet?

Dr. Rheaume-Bleue explains how Vitamin K2 has been disappearing from our diet, and what are the best Vitamin K2 supplements (menaquinone 7 made from natto) to use and why.

Which are Vitamin k2 rich foods?

You can get the most vitamin K2 by eating Japanese fermented soy beans called natto, and some from egg yolks, butter and eating the fat from grass-fed animals.

But, you say, these are exactly the things you have been advised NOT to eat for your heart.  Surprise!

You CAN Reverse Heart Disease!

If Vitamin K2 is needed for your arteries NOT to clog up in the first place, what about removing plaque once it has formed?


  • There have been studies showing that if you add Vitamin K2 (menaquinone 7) to your diet, you can reduce the calcium content in your arteries by half, or 50%.

Studies show that this can be effective in just 6 weeks!

  • If this is sounding better than surgery to counteract the warfarin side effects such as calcium build up and bleeding strokes, read on…

Studies also show that Vitamin K2 also helps improve the flexibility of the arteries once the calcium is gone!

THIS IS GOOD NEWS, because that means that you CAN reverse the “hardening of your arteries!”

Even more GOOD NEWS!

Vitamin K2 works by activating another protein that encourages the immune system to CLEAR OUT the arterial garbage!

This action is gentle, and is better than INFLAMMATION!

Our arteries get damaged when our immune system tries to clear up the problem and launches an all out inflammatory attack. This, unfortunately, encourages plaque to collect as a “defense” against the inflammation.

What About My Coumadin Food List?

If you are taking Coumadin to prevent having a stroke, you need to know how vitamin K1 and K2 are different, so you know how to prevent warfarin side effects.

Vitamin K2 has to do with CALCIUM metabolism, and helps prevent the build-up of calcium in the arteries and the aortic valve.

On the other hand, your warfarin vitamin k diet has only to do with vitamin K1, which is the blood thinning vitamin.

Vitamin K1 rich foods are typically green veggies, and you will want know which foods need to be constant in such a warfarin diet. 

Your Coumadin food list will typically NOT stop you from eating Vitamin K2 rich foods, such as natto, egg yolks, hard cheeses and butter and fat from grass fed cows.

  • Yes, go ahead, get the very best source -- natto (fermented soy beans) or moderate sources from -- animal fats from grass fed animals with Vitamin K2!!!
  • Even though the advice to limit egg yolks and animal fats to prevent heart disease is still common -- saturated fat has NOT been effectively linked to coronary heart disease. This is very good news for helping against warfarin side effects.

Dangerous Warfarin Side Effects Long Term?

Let me explain the puzzle of Warfarin.  How can something you are taking to PREVENT a stroke, cause one?

You are taking Coumadin to PREVENT a stroke, yes?

So, how can bleeding strokes be among the side effects of warfarin?

This is because this blood thinner medication has, what’s known as a “narrow therapeutic range.”

This means that it is easy to take either too much or too little of it, with the “middle” being the “safe” range.

  • With TOO LITTLE Coumadin dosage you get unwanted blood clots causing a stroke, but with TOO MUCH, amounting to a Coumadin overdose, you are instead in danger of another type of stroke called a “bleeding stroke.”

That is why your doctor regularly takes your INR, and recommends a warfarin diet – a warfarin vitamin k diet – to keep your vitamin K1, the “clotting vitamin” in a SAFE RANGE.

Getting your Coumadin dosage right is very tricky, but with a warfarin diet your risk of a Coumadin overdose causing bleeding, is less likely.

But there’s more…

Even if you get your Coumadin dosage right, here’s the kicker…

  • Researchers also found that when people take Coumadin over an extended period of time, there’s MORE of a build-up of calcium in their arteries than in people who are NOT taking Coumadin to prevent blood clots.
  • Now, in case you don’t immediately catch the irony of this situation of warfarin side effects…

A build-up of calcium in your arteries is a leading coronary heart disease, or hardening of the arteries!

This build up of calcium causes a rigidity in, and a narrowing of your blood vessels, and this is likely to cause an unwanted event such as a heart attack or a stroke. How?

Calcified arteries are more likely to get blocked, and this can stop the flow of blood and oxygen to the heart or the brain, causing a heart attack or a stroke.

  • If you are beginning to wonder if you can avoid warfarin side effects long term, such as a build-up of calcium, here the other half of the story you need to know…

Why a Warfarin Vitamin K Diet?

Fortunately, if you want to avoid warfarin side effects, there’s good news.

Yes you need your Coumadin food list. Why?

No, you do NOT need to AVOID foods with vitamin K1. Rather, you need to keep the amount of vitamin K1 you take in your diet at a CONSTANT level so as not to cause Coumadin food interactions -- “too much” leading to bleeding or “too little” leading to blood clots...

But a warfarin vitamin k diet that limits vitamin K1 is only half the story!

Even with a Warfarin diet you will want to ADD foods and supplements with Vitamin K2 to prevent the serious warfarin side effects.

Consider a Natural Coumadin Alternative

To stop warfarin side effects, please don’t stop Coumadin cold turkey. Have your doctor help you decrease your prescription gradually.

  • There is an FDA approved Coumadin alternative to stop heart disease if your doctor objects to your taking a vitamin K2 or menaquinone 7, or MK 7 supplement.

Meet Dr. Harry Elward:

  • Dr. Harry’s "dissolve blood clots" Protective Formula can be safely used along with your Coumadin prescription while your doctor monitors your progress.

This can avoid Coumadin side effects, because this formula will not interfere with warfarin's blood thinning action.

  • Your doctor will not likely want you on a vitamin K2 supplement, even one sourced from natto: MK-7.

Instead, you can safely try a supplement like Dr. Harry's ENHANCED Formula, that doesn’t interfere with Coumadin.  By adding such a supplement your doctor can help you reduce this blood thinning medication.  You can thus lessen warfarin side effects, especially the dangerous long-term side effects of warfarin.
