Your heart is an extraordinary engine, beating over 100,000 times a day to deliver oxygen and nutrients throughout your body. While food, movement, sleep, and stress management are foundational, supplements for heart health can help fill nutrient gaps. But what are the best supplements for heart health? Keep reading to find science-backed insights and answers to your most asked questions about heart health supplements, including garlic, omega 3‑6‑9, and CoQ10.
Why Heart Health Matters
The pumping action of your heart means blood travels past your lungs, picking up oxygen to carry through your arteries to reach every cell in your body. Along the way, blood also passes the digestive tract, where it picks up nutrients, bringing those building blocks to your cells. Every beat of the heart delivers oxygen and nutrients to fuel the brain, muscles, and organs. This supports everything from focus to movement, digestion to daily functioning.
What Are the Best Supplements for Heart Health?
The best supplements for heart health are those that provide nutrients that support the everyday functioning of the heart and blood vessels. There’s a lot involved in maintaining heart health, from supporting blood flow andflexibility of blood vessels, to balancing blood lipids (e.g. cholesterol) and protecting against everyday free radical damaging. Come discover some of the best nutrients for heart health, and whether you’re getting enough. If you’re not, don’t worry – below are the science-backed facts you need to know to find the best heart health supplements for your needs.
What Should You Eat for Optimal Heart Health?
Vegetables, fruits, legumes, nuts, seeds, healthy oils, and fatty fish are consistently recommended as pillars of a heart healthy diet, from the Mediterranean diet to the DASH diet. These foods are rich in fiber, vitamins, antioxidants, and healthy fats known to support heart health. Eating these healthy foods as part of a balanced diet can help support heart health. However, if you find it hard in your busy lifestyle to get enough of these healthy foods, we’rehere to support you with supplements to fill any nutritional gaps.
What Is the Best Vitamin or Nutrient for Heart Health?
While no single nutrient works alone, there are some well-researched supplements that support heart health, including garlic, omega 3‑6‑9, and coenzyme Q10 (CoQ10). These are among the best supplements for heart health – the best part is that they each support different cardiovascular functions.
What Does Garlic Do for Heart Health?
Garlic is one of the most researched supplements for heart health, with over 108 human clinical trials. Garlic supports cardiovascular health by helping maintain healthy blood lipid levels.
How Much Garlic Should You Take for Heart Health?
According to Health Canada, adults should consider a minimum of 0.5 g per day and not exceed 12 g per day. With Nature’s Bounty Garlic it’s easy to choose the amount that’s right for you - each softgel contains 1000mg (1g) of garlic, while one Garlic 2000 mg tablet delivers 2 g of garlic in a single tablet.
Is Omega 369 Good for the Heart?
Most Canadians don’t realize how important essential fats (omega-3s and omega-6s) are for long-term good health, including heart health. Essential fatty acids cannot be produced by the body, making it important that you get enough in your diet, or support with supplements.
Omega-3s: There are different types of omega-3 fatty acids, with the most beneficial for heart health being EPA and DHA, according to research. Found primarily in fish, but also available in supplements, consuming EPA and DHA may reduce triglyceride levels, according to Health Canada.
Omega‑6s: Found in vegetable oils, whole grains, nuts, and seeds, these healthy fats play a role in the body’s inflammatory pathways. One omega-6 in particular, called LA, scientists think plays a role in heart health.
Omega‑9s: While not essential fatty acids, these fats contribute to cell structure.
Make heart health part of your everyday routine with Nature’s Bounty Omega 3‑6‑9—three omegas, one easy choice.
What Are the Benefits of Taking CoQ10 for Heart Health?
Coenzyme Q10 (CoQ10) is an antioxidant found in high concentrations in the heart. CoQ10 protects the heart from damage caused by free radicals. Free radicals are highly reactive molecules that cause damage to cells and play a role in the development of heart disease. The body’s ability to make CoQ10 declines with age, which increases our need to consume more CoQ10. Meat, fish, nuts and some oils are food sources of CoQ10, and for additionalsupport there are CoQ10 supplements.
How to Choose a CoQ10
There are different forms of CoQ10 supplements to choose from. Since the body’s ability to absorb CoQ10 isn’t great, it’s important to reach for a CoQ10 supplement with good bioavailability. Q-SorbTM is a form of CoQ10 that has good bioavailability. Your heart does a lot of hard work – we're here to help – using our bioavailable Q-SorbTM form of CoQ10 to better support your body.
CoQ10 supplements are available in two forms: CoQ10, the inactive form, and ubiquinol, the active form used by the body. In the body, CoQ10 is converted into ubiquinol. For some people, choosing ubiquinol may be preferred, as it results in higher CoQ10 levels in the blood compared to CoQ10.
A study in which Nature’s Bounty CoQ10 Ubiquinol (Kaneka) levels rose eightfold in 4 weeks using 200 mg per day of the ubiquinol.
What Is the Best Thing to Strengthen Your Heart?
Movement is one of the best things you can do to strengthen your heart. But an estimated 31% of people worldwide don’t meet existing recommendations for daily physical activity. Doing movement that raises your heart and breathing rate for 150 minutes a week (22 minutes per day) was linked with a 14% lower risk of coronary heart disease than those who don’t exercise in a large study. Surprisingly, there are health benefits to even just a little exercise, says researchers - even just moving for 2.2 minutes a day can offer some protection if you’re not active.
What Is the Fastest Way to Improve Heart Health?
Consistent, small daily actions, such as focusing on eating nourishing foods, physical activity, and stress reduction can be an effective approach. You can support heart health, when needed, with the use of appropriate supplements. For personalized advice on which supplements are best for you, speak with a health care professional.
