What Is the Most Effective Natural Blood Thinner?

Last modified on June 23rd, 2023

Many Americans need or already take blood thinning medication, and they can be a life-saving medication.

At the same time, you may wonder what natural blood thinner options are for various reasons.

Natural blood thinner options should never be a substitute for your doctor’s medicine.

You should always speak to your doctor first and foremost about your health issues and determine if blood thinning medications are right for you.

Some natural blood thinners may not work as effectively as prescription thinners.

Using natural blood thinners with your prescription medication could create adverse side effects and interactions.

With that being said, if you aren’t at the point where you need a prescription blood thinner but you’d like some related health benefits, you might consider natural blood thinners instead.

What Are Blood Thinners?

Blood thinners are medicines that allow for the smooth flow of blood through your arteries and veins. Blood thinners can prevent blood clots from forming.

They can also keep blood clots from getting bigger.

If you have some type of heart defect or disease, you may be at great risk of developing dangerous or deadly clots, so your doctor might put you on blood thinners.

While blood thinners can reduce your risk of stroke or heart attack, these prescription medications do have risks.

For example, if you get a cut or a wound, you may bleed more than you would typically.

Types of Blood Thinners

There are two primary categories of blood thinners—anticoagulants and antiplatelets.

Anticoagulants work by preventing blood from clotting, and these are often taken as a pill.

Brand name blood thinners that are anticoagulants include:

  • Eliquis
  • Pradaxa
  • Xarelto
  • Coumadin

Antiplatelets target the particles in the blood, which are called platelets. These include:

  • Aspirin
  • Plavix
  • Persantine
  • Effient
  • Brilinta
  • Zontivity

Blood thinners don’t really thin your blood or break up clots, but they can prevent the formation of new clots.

Anticoagulants work by competing with the vitamin K that comes from your liver.

Your body requires vitamin K to make clotting factors, a protein type.

These clotting factors help platelets and blood cells bind together.

Antiplatelets prevent platelets from sticking to one another and your blood vessel walls.

Antiplatelets are a weaker version of blood thinners than anticoagulants.

An estimated two to three million Americans take blood thinners annually. They’re often prescribed for people who have a history of heart attack or stroke to prevent a recurrence.

If you have a blood vessel or heart disease, deep vein thrombosis, or lupus, you might also be prescribed to take a blood thinner.

People who are overweight or obese are at greater risk of blood clots, as are individuals who recently had surgery or people with an artificial heart valve.

Some people take blood thinners for a few months, while others take them indefinitely.

The Risks of Blood Thinners

We want our blood to be able to clot to an extent because if you hurt yourself, that clotting prevents excessive blood loss.

Since blood thinners prevent clotting, you can anticipate bleeding more than usual if you hurt yourself.

People who are on blood thinners have to be careful about their activities as a result.

With some blood thinners, your doctor will do regular blood tests to ensure you take the right dosage.

What Puts You At Risk For Blood Clots?

Clots occur in the arteries or veins, which are part of your circulatory system. When an abnormal clot forms in a vein, it can cause pain and it can restrict blood flow to the heart.

There is also a situation called a pulmonary embolism, where a clot can detach and travel through the heart

Some of the risk factors for developing blood clots include:

  • Obesity
  • Pregnancy
  • Immobility
  • Oral contraceptives
  • Certain cancers
  • Smoking
  • Trauma
  • Surgeries
  • Being over the age of 60
  • Having a family history of blood clots
  • Chronic inflammatory diseases
  • High blood pressure
  • Diabetes
  • High cholesterol

What Are the Symptoms of a Blood Clot?

Some of the symptoms of a blood clot can include chest pain or heaviness, discomfort in the upper body, shortness of breath, sweating, light-headedness, and nausea.

These symptoms may indicate a blood clot in or near the heart.

A brain blood clot can include symptoms like weakness of the face or limbs, problems speaking, vision trouble, headaches, and dizziness.

In the arm or leg, you might experience sudden or gradual pain, swelling, warmth, and tenderness.

In the lung, you may feel a racing heart, shortness of breath, sweating, coughing up blood, fever, or sharp pain in the chest.

Blood clots in the abdomen can create symptoms like severe pain, diarrhea, and vomiting.

Risks of Prescription Blood Thinners

While you should always listen to your doctor as far as any medications and let them know of side effects you may experience, some are possible with blood thinners.

Some of the most commonly experienced side effects of blood thinners include:

  • Some people may experience low red blood cell counts when they’re on a blood thinner, which can mean anemia. Symptoms of anemia can include weakness, fatigue, dizziness, and shortness of breath.
  • You have to be sure to inform your doctor about any other medicines or supplements you take along with blood thinners, to avoid potentially dangerous interactions. For example, antifungal medications and some antibiotics can strengthen the potency of blood thinners and increase your risk of bleeding.
  • Don’t skip a dose of your blood thinner ever, and if you forget to take it for a day, speak with your doctor about what you should do.
  • Keep an eye out for signs of internal bleeding. Symptoms of internal bleeding may include pale skin, stools that look black or tarry, fatigue, and shortness of breath.
  • You have to be very careful to avoid trauma such as falls or cuts when on blood thinners because you could experience significant bleeding.
  • You aren’t supposed to drink alcohol with blood thinners because alcohol may impact how the medicine is processed in your liver and could increase the amount of medicine in your bloodstream.

How to Thin Blood Naturally

If you want to reduce blood clotting risks naturally and thin blood with dietary supplements, and you’ve spoken to your doctor, the following are some good picks.

It’s important to note these aren’t a replacement for medication, and you should never take a supplement with medicine without talking to your doctor.

Dietary supplements with the ability to thin blood naturally may be a good part of your overall heart health routine, and they may reduce the risk of blood clots that potentially lead to serious events such as stroke and heart attack.

In addition to being a natural blood thinner, according to the Mayo Clinic, vitamin E might improve symptoms of nonalcoholic fatty liver disease. Some research has also shown high doses of vitamin E might slow the progression of Alzheimer’s in people diagnosed with the disease.

Another study in young women looked at a dose of 400 mg of something called proanthocyanidin that comes from GSE, followed by six hours of sitting. It reduced edema and leg swelling by 70%.

GSES can also support brain health and improve cognitive status and prevent memory loss. It may also reduce amyloid clusters in the brain and brain lesions.

A 12-week study in healthy older adults found taking 150 mg of GSE improved immediate and delayed memory, language and attention.

The antioxidant properties of GSE have been shown to inhibit many types of cancer cells in a lab setting, including breast, gastric, lung, liver, prostate and pancreatic.

This very popular herbal supplement is similar to taking blood thinning medications.

Bromelain can be taken in different supplement forms, including as a pill or tablet.

There have been many reviews and studies looking at the potential benefits of bromelain. For example, there was a review of clinical studies that found that since bromelain has natural anti-inflammatory and pain-relieving properties, it might be helpful in the treatment of osteoarthritis.

An animal study showed bromelain might help people with asthma or other forms of airway disease, and it’s sometimes used as a treatment for chronic rhinosinusitis.

An animal study showed that bromelain helped heal the ulcers associated with inflammatory bowel disease.

Bromelain can positively affect platelet function in a way that's similar to a prescription blood thinning drug.
