If you are concerned about protecting the health of your heart, there are several important heart health supplements that have been shown to have beneficial effects on the heart and cardiovascular system (including the blood vessels, arteries and brain in many cases).

In addition to providing a comprehensive list of heart health supplements in this post, you will also find information on lifestyle changes that may help prevent health problems, and details on how to follow a heart smart diet.  If you have a heart condition or for a high risk for a heart attack, you must follow your doctor’s advice. If you think you may have a heart condition but have not seen a doctor, it is essential that you consult a physician for a proper diagnoses. Do not try to treat a serious health condition on your own with over-the-counter supplements without consulting a medical professional.

This post will discuss the following KEY heart health supplements:

  • CoQ10:
  • Hawthorn:
  • Grapeseed Extrat
  • Arginine:
  • Curcumin
  • collagen
  • Fish Oil/Omeg a-3 fatty acids:
  • Garlic:
  • Astaxanthin:
  • Green tea
  • Vitamin C

Lifestyle Habits for  Heart Health

In addition to taking specific supplements to combat heart disease, apply these general guidelines to your diet and lifestyle:

1. Cut back on salt

Too much salt in your blood creates an osmotic gradient that draws water into the bloodstream. The result is high

A couple days ago when I looked in the mirror in the morning, I noticed a crease on my ear lobe.  I immediately recalled that I had read something some where about a crease or wrinkle on the ear lobe being indicative of a serious health condition, however , I couldnt recall the details. I immediately ran in internet search and, sure enough, a diagonal crease on the earlobe, pointing toward the shoulder, can be an indicator of heart disease, often present in people who die of sudden cardiac arrest (in otherwords, they weren’t even aware they had heart disease prior to the cardiac arrest). Sigh… in my case, I have sleep apnea attacks which feel like my heart has stopped; my heart frequently pounds, flutters, and palpitates, and I have high blood pressure. So, this is hardly shocking.

I immediately set about compiling research on which supplements I should be taking for cardiovascular health. I already happened to have several on hand in my ‘war-chest’. So I started taking them immediately.  I’ll be adding to the list, based on my ongoing research which I am compiling on this page.

Your  heart pumps blood to different parts of your body through a system of arteries, veins and vessels which total  nearly 100,000 miles for an adult—that’s 4 times the circumference of the Earth!

For this reason its essential to support healthy blood vessels. Blood vessels that feed the heart muscle can be blocked causing a heart attack. Vessel health is key: avoid smoking, be active, manage stress, and eat a whole foods diet.

Best Heart Health Supplements


Read here about CoQ10,  Look for supplements that contain ubiquinol, the form of CoQ10 that is naturally produced in the body and more readily absorbed when taken in supplement form. If you can, skip supplements containing ubiquinone, which is more common, but widely seen as less effective.

Grapeseed Extrat


Arginine synthesizes nitric oxide, which helps your blood vessels relax and expand. This is important for regulating your blood flow.  Aginine is beneficial if you have certain conditions that affect your blood vessels and heart such as  coronary artery disease, peripheral vascular disease, clogged arteries, angina, or erectile dysfunction. Arginine supplements may also benefit people with peripheral vascular disease (PVD). This condition develops when your arteries narrow and reduce blood flow to your limbs. Most people with PVD develop it in their legs. Many cases of erectile dysfunction (ED) may be linked to heart disease. Problems with blood vessels can reduce the flow of blood to the penis. According to the Mayo Clinic, some research suggests that arginine supplements may help improve blood flow through the body. Due to these purported benefits, doctors sometimes prescribe arginine supplements to treat ED. Studies have found that arginine supplements may help alleviate ED in men with low nitrate levels. A study reported in Urology also found that oral supplements of L-citrulline may help treat mild to moderate ED. Your body converts L-citrulline into L-arginine.  Therefore when taking Arginine, it can be beneficial to also take citrulline. Adding collagen, hyralic acid and vitamin c to the mix is also a good idea, as all of these supplements work together synergistically for maximim benefit.

However, the Mayo Clinic warns that taking arginine supplements after a heart attack may have adverse effects. Aginine could increase the risk of dying after a heart attack. More research is needed to assess the benefits and risks. Until the potential safety issues have been addressed, don’t take arginine supplements after a heart attack.

If you have a history of heart disease, ask your doctor about the potential benefits and risks of arginine supplements. Depending on your health history, it may or may not be advisable.


It is said that curcumin may be the most effective natural supplement available, with effects on both the brain and the body.  Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant. However, the curcumin content of turmeric is not that high. It’s around 3%, by weight (2).  It would be very difficult to reach therapeutic levels of curcumin just using the turmeric spice in your foods. Therefore, if you want to experience the full effects, you need to take a supplement that contains significant amounts of curcumin.  Unfortunately, curcumin is poorly absorbed into the bloodstream. It helps to consume black pepper with it, which contains piperine, a natural substance that enhances the absorption of curcumin by 2,000%.  Because curcumin is fat soluable, its also a good idea to take it with a meal.

Curcumin has beneficial effects on several factors known to play a role in heart disease. Perhaps the main benefit of curcumin when it comes to heart disease is improving the function of the endothelium, which is the lining of your blood vessels. It’s well known that endothelial dysfunction is a major driver of heart disease and involves an inability of your endothelium to regulate blood pressure, blood clotting and various other factors (29).  Several studies suggest that curcumin leads to improvements in endothelial function. One study found that it’s as effective as exercise while another shows that it works as well as the drug Atorvastatin (30, 31).

In addition, curcumin reduces inflammation and oxidation (as discussed above), which play a role in heart disease as well. One study randomly assigned 121 people, who were undergoing coronary artery bypass surgery, either a placebo or 4 grams of curcumin per day, a few days before and after the surgery. The curcumin group had a 65% decreased risk of experiencing a heart attack in the hospital.


Researchers have theorized that taking collagen supplements may help reduce the risk of heart-related conditions. Collagen provides structure and flexibility to your arteries, the blood vessels that carry blood from your heart to the rest of your body. Without enough collagen, arteries may become weak and fragile.  This may lead to atherosclerosis, a disease characterized by the narrowing of the arteries. Atherosclerosis has the potential to lead to heart attack and stroke.

In one study, 31 healthy adults took 16 grams of collagen daily for six months. By the end, they had experienced a significant reduction in measures of artery stiffness compared to before they started taking the supplement (22).

Additionally, they increased their levels of “good” HDL cholesterol by an average of 6%. HDL is an important factor in the risk of heart conditions, including atherosclerosis (22).


Fish Oil/Omeg a-3 fatty acids:

Omega-3 fatty acids are among the most important nutrients when it comes to cardiovascular health. There is extensive science that supports the use of omega-3 fatty acids to maintain healthy blood pressure and cholesterol.

They play an important role in regulating the cardiovascular system. There are three main types of omega-3 fatty acids. ALA (alpha-linolenic acid) is classified as an essential fatty acid, because the human body needs, but doesn’t produce it on its own.

The other two types are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). It’s EPA and DHA that seem more important for heart health, being more anti-inflammatory.

It may seem counter-intuitive that the body needs these “good” fats to prevent the build-up of plaque. It’s important to distinguish between the types of fat needed to function properly and support, and bad types of fat (ie. hydrogenated oils), which are now known to be inflammatory and damaging to blood vessel lining.

Omega-3 fats are one of the good kinds, and studies have shown that they can support inflammation, blood pressure, and keep the heart beating steadily.

Fish, nuts, and seeds are high in omega-3 fats, with the priority going to fish sources, as they are highest in the EPA and DHA fats. Incorporate them into your diet, or look for a quality supplement, such as fish oil supplements derived from salmon or cod.


It may slow the buildup of plaque in your arteries, lowering your risk of blood clots. Research shows that both garlic in food and in supplements may help.  Garlic contains a variety of trace minerals and vitamins. Evidence suggests that components in garlic inhibit the synthesis of cholesterol, dissolve blood clots, and regulate heart rate–all of which can lead to improved heart health.  There is a large body of evidence suggesting garlic can support both cholesterol and blood pressure.


Strong research shows that astaxanthin can support heart health, in addition to its anticancer and anti-inflammatory effects. Recent clinical studies suggest astaxanthin supports cardiovascular health, and helps maintain cholesterol levels already within a normal range. Astaxanthin was shown to lower LDL (bad) cholesterol and increase HDL cholesterol (a.k.a. the “good” kind of cholesterol).

As an added bonus, further research is being conducted to explore astaxanthin’s other potential benefits, including supporting brain function and reducing signs of aging in the skin.   More about Astaxanthin,

Green tea . \

Research shows that both the extract and the drink may lower LDL cholesterol and triglycerides, and raise HDL levels.

  Vitamin C

May Lower Your Blood Pressure and Help Keep Arteries Flexible. Well Known for Helping Your Blood Vessels to Relax.

  • A daily dose of vitamin C may have a similar effect as walking on a protein called endothelin-1, which promotes the constriction of small blood vessels
  • Overweight or obese adults who took vitamin C daily reduced endothelin-1-mediated vessel constriction as much as those who walked daily
  • When endothelin-1 activity is higher it makes small blood vessels more prone to constricting, which increases the risk of heart disease
  • Vitamin C supplementation represents an effective lifestyle strategy to reduce blood vessel constriction in overweight and obese adults, particularly since many people do not engage in recommended levels of daily physical activity

Lifestyle Habits for  Heart Health

In addition to taking specific supplements to combat heart disease, apply these general guidelines to your diet and lifestyle:

1. Cut back on salt

Too much salt in your blood creates an osmotic gradient that draws water into the bloodstream. The result is high blood pressure, which can weaken and potentially damage the walls of blood vessels. This also makes the heart work harder to pump blood throughout the body. The American Heart Association recommends no more than 1,500 mg/day of sodium for adults.

Most of the salt that Americans consume come from packaged foods or restaurant meals. Look first to decrease the amount of these foods in your diet.

2. Reduce your intake of saturated and trans fats

Trans fats like hydrogenated oil increase the amount of bad cholesterol in the body and increase inflammation. Overconsumption of saturated fats may contribute to the accumulation of plaque in the bloodstream. Avoiding trans fats completely, and moderating saturated fat directly reduces their negative impact on your cardiovascular system.

4. Stay Active & Exercise

Physical activity lowers risks for cardiovascular disease by controlling weight gain, increasing the amount of good cholesterol in the body, and regulating blood pressure. Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity (or an equal combination of both) each week.  Regular physical activity can help you maintain your weight, keep off weight that you lose and help you reach physical and cardiovascular fitness. If it’s hard to schedule regular exercise sessions, look for ways to build short bursts of activity into your daily routine, like parking farther away and taking the stairs instead of the elevator. Ideally, your activity should be spread throughout the week.

5. Manage stress: the mind-body connection

Stress and anger are a physical, as well as psychological burden. These factors can increase your likelihood of getting a stroke. Manage stress by meditating, building a strong support network, and visiting a mental health provider, if necessary.

Control Your Weight

Speciically, carrying fat around the mid section can predispose you to a heart attack.

3. Don’t Smoke

Smoking and secondhand smoke cause stress on the body and especially the heart. Quitting smoking is painful at first, but the benefits are well worth it. Positive changes, such as a lower heart rate, occur as soon as 20 minutes after smoking. The risk of a heart attack drops within the first 24 hours, while plaque build-up slows down over time.

Eat a Heart Smart Diet

Eat a diet that emphasizes:

Limit intake of saturated fat, trans fat, sodium, red meat, sweets and sugar-sweetened beverages. If you choose to eat red meat, compare labels and select the leanest cuts available.

One of the diets that fits this pattern is the DASH (Dietary Approaches to Stop Hypertension) eating plan. Most healthy eating patterns can be adapted based on calorie requirements and personal and cultural food preferences.

Eat less nutrient-poor foods.

The right number of calories to eat each day is based on your age and physical activity level and whether you’re trying to gain, lose or maintain your weight. You could use your daily allotment of calories on a few high-calorie foods and beverages, but you probably wouldn’t get the nutrients your body needs to be healthy. Limit foods and beverages high in calories but low in nutrients. Also limit the amount of saturated fat, trans fat and sodium you eat. Read Nutrition Facts labels carefully — the Nutrition Facts panel tells you the amount of healthy and unhealthy nutrients in a food or beverage.

As you make daily food choices, base your eating pattern on these recommendations:

  • Eat a variety of fresh, frozen and canned vegetables and fruits without high-calorie sauces or added salt and sugars. Replace high-calorie foods with fruits and vegetables.
  • Choose fiber-rich whole grains for most grain servings.
  • Choose poultry and fish without skin and prepare them in healthy ways without added saturated and trans fat. If you choose to eat meat, look for the leanest cuts available and prepare them in healthy and delicious ways.
  • Eat a variety of fish at least twice a week, especially fish containing omega-3 fatty acids (for example, salmon, trout and herring).
  • Select fat-free (skim) and low-fat (1%) dairy products.
  • Avoid foods containing partially hydrogenated vegetable oils to reduce trans fat in your diet.
  • Limit saturated fat and trans fat and replace them with the better fats, monounsaturated and polyunsaturated. If you need to lower your blood cholesterol, reduce saturated fat to no more than 5 to 6 percent of total calories. For someone eating 2,000 calories a day, that’s about 13 grams of saturated fat.
  • Cut back on beverages and foods with added sugars.
  • Choose foods with less sodium and prepare foods with little or no salt. To lower blood pressure, aim to eat no more than 2,300 milligrams of sodium per day. Reducing daily intake to 1,500 mg is desirable because it can lower blood pressure even further. If you can’t meet these goals right now, even reducing sodium intake by 1,000 mg per day can benefit blood pressure.
  • If you drink alcohol, drink in moderation. That means no more than one drink per day if you’re a woman and no more than two drinks per day if you’re a man.
  • The American Heart Association recommends that all adults eat at least two 3.5-ounce servings of fish a week.
  • Follow the American Heart Association recommendations when you eat out, and keep an eye on your portion sizes.

 Fiber and Sterols for Your Heart

Fiber. Found naturally in fruits, grains, vegetables, and legumes, fiber cuts down the amount of cholesterol your body soaks up from food. Try to get at least 25 to 30 grams of it every day. Men less than age 51 should aim for 38 grams a day. It’s best to get your daily dose from your diet, but supplements are another option. There’s good evidence that blond psyllium husk — common in fiber supplements — can lower “bad” LDL cholesterol. It can also raise the “good” kind, HDL. Other fiber supplements include methylcellulose, wheat dextrin, and calcium polycarbophil.. If you take a fiber supplement, increase the amount you take slowly. This can help prevent gas and cramping. It’s also important to drink enough liquids when you increase your fiber intake.

Sterols and stanols. Find these in foods like nuts and grains, or you can buy them as supplements. They reduce the amount of cholesterol that your body absorbs from food. They’re also added to many foods, such as some margarines, orange juice, and yogurts. Experts recommend 2 grams a day to help lower LDL cholesterol for people who have high cholesterol.
