When it comes to taking care of your heart, misinformation can steer you off course from what really matters. Despite decades of research, myths continue to shape how people think about cardiovascular wellness, and some of those misconceptions may lead to habits that work against the body rather than for it.

The heart is the most energy-demanding organ in the body, and each heart cell (cardiomyocyte) contains a very large number of mitochondria. This means that your heart requires regular support at every stage of life.

Separating fact from fiction is essential to making informed choices for your wellness. Here are eight of the most common heart health myths and what cur

Myth: Heart health is only a concern for older adults.

Fact: Supporting heart health matters at every age, and healthy habits early can make an impact.

It’s a common assumption that cardiovascular concerns are reserved for retirement age. In reality, factors affecting the cardiovascular system can begin accumulating as early as adolescence.

Lifestyle habits established in the 20s, 30s, and 40s make a meaningful difference for cardiovascular health over time, including choices around diet, physical activity, sleep quality, and stress management. But that doesn’t mean there’s a time that’s too late to start thinking about your heart. If you’re looking for a starting point, exploring our new health rules at ages 40, 50, and 60 can help.

The young adult years are often spent thinking about careers, travel, family activities, or even just the weekend’s plans — not usually heart health. Nearly half of adults between 18 and 29 years old do not have a primary care physician.

That means most young adults are not thinking about cholesterol as much as older adults. But the reality is, cholesterol is an important heart health metric at all stages of adulthood. The American Heart Association recommends that adults begin having their cholesterol checked starting at age 20, with follow-ups every four to six years, depending on their unique needs. There’s also a strong genetic component to cholesterol levels, so knowing your family history and establishing a baseline early gives you a clearer picture of long-term cardiovascular wellness.

Remember that cholesterol is just one piece of the heart health puzzle. Understanding your heart health numbers (including cholesterol, blood pressure, and blood sugar), is one of the simplest and most impactful things a person of any age can do.

Myth: Heart health is primarily a priority for men.

Fact: Cardiovascular issues affect women for a number of reasons, and symptoms may present differently.

When you think of someone at the cardiologist’s office, who do you imagine? You likely imagine a male, but that’s one of the biggest misconceptions about heart health. According to the CDC’s data on women and heart health, cardiovascular conditions are a leading health concern for women. Yet, many women underestimate the factors that impact their heart health, including lifestyle changes and the biological changes that come with age or menopausal stages.

Women’s heart health is unique because symptoms related to heart health concerns are often different for women than they are for men. Being aware of the signs for heart health complications that commonly affect women is key to living a heart-healthy lifestyle at all stages of adulthood. For example, while chest discomfort is common across all populations, women may also experience:

• Shortness of breath
• Nausea
• Fatigue
• Discomfort in the back, jaw, or neck

These less typical presentations can lead to delayed recognition. In reality, heart health deserves equal attention regardless of gender, and understanding the full range of how the cardiovascular system communicates is essential.

Myth: If there are no symptoms, the heart must be fine.

Fact: Many factors that affect heart health develop without any noticeable signs.

It can be easy to assume the “out of sight, out of mind” mentality when it comes to heart health, especially if you feel physically fine. The idea that your heart does not need support unless there are symptoms can create a false sense of security. Several key markers of cardiovascular wellness, including blood pressure and cholesterol, can change without any symptoms. In fact, high blood pressure frequently goes undetected without regular monitoring.

This is exactly why regular health screenings matter. Screening tests during routine appointments can identify changes early, when lifestyle adjustments tend to have the greatest impact.

Myth: A family history of heart issues means I do not have agency over my cardiovascular wellness.

Fact: Genetics may impact your heart health, but lifestyle choices play a powerful role in cardiovascular outcomes.

Family history is one factor among many that can influence heart health, but it doesn’t write the entire story. Research has demonstrated that cardiovascular health is largely associated with modifiable lifestyle factors around diet, exercise, sleep, stress management, and smart supplementation.

Even for individuals with a family history of cardiovascular complications, proactive lifestyle choices can make a meaningful difference. A balanced diet, combined with regular physical activity, quality sleep, and stress management, all contribute to maintaining cardiovascular wellness over time. If you’re ready to start building your heart health routine, explore these 10 lifestyle changes to support heart health.

Myth: Exercise has to be intense to benefit the heart.

Fact: Even moderate, consistent physical activity supports cardiovascular wellness.

The idea that heart-healthy exercise means running marathons or spending hours at the gym keeps many people from starting at all. In reality, you should aim for at least 150 minutes (or between two to three hours) per week of moderate-intensity aerobic activity. And yes, simple exercises like brisk walking or gardening are just as effective as more classic cardio exercises like running, cycling, or swimming.

When it comes to exercise for a healthy heart, consistency matters more than intensity. Regular moderate activity supports healthy blood pressure, helps maintain a healthy weight, promotes better sleep, and supports the body’s overall cardiovascular function. Even breaking activity into shorter sessions throughout the day can be beneficial.

At the cellular level, physical activity supports mitochondrial function: the process of producing cellular energy within the body’s cells. The heart particularly benefits from regular movement that supports healthy cellular energy production.

Myth: Emotional stress doesn’t affect the heart.

Fact: Psychological and emotional well-being are directly connected to cardiovascular health.

Stress on the heart does not have to be physical. Emotional distress can put plenty of strain on your heart, and intense feelings of grief, a major loss, or extreme stress can have a measurable impact on heart function.

Prolonged emotional stress can elevate cortisol levels, which can affect blood pressure, sleep quality, and overall cardiovascular health. Managing stress through mindfulness, physical activity, social connection, and adequate sleep promotes your mental health and a heart-friendly lifestyle. Explore the benefits of breathwork for stress management and cardiovascular wellness.

Yet, there’s another kind of stress that goes even deeper than emotions: oxidative stress. This is when the body has an imbalance of antioxidants and free radicals (or molecules produced as a result of cellular energy production and that arise from exposure to environmental sources, such as smoke, car exhaust, and toxic chemicals). This imbalance can cause damage to cells, including the many cells that support the heart’s function. That’s why supporting the body’s natural antioxidant capacity is one component of overall cardiovascular wellness.

Myth: Supplements can replace a heart-healthy lifestyle.

Fact: Supplements work best as part of a holistic approach to cardiovascular wellness, not as a substitute for healthy habits.

No single supplement, vitamin, or nutrient can compensate for consistent lifestyle habits. A heart-healthy lifestyle is built on a foundation of balanced nutrition, regular movement, quality sleep, stress management, and smart supplementation.

To understand supplements and heart health, we need to look deep. CoQ10, for example, is a naturally occurring nutrient with two forms: ubiquinone (the oxidized form) and ubiquinol (the active antioxidant form). Both play a foundational role in cellular energy production — particularly in the heart, which contains a very large number of mitochondria to fill its high cellular energy demand.

As we age, the body’s ability to efficiently convert ubiquinone into ubiquinol declines, and our susceptibility to oxidative stress and cellular damage increases. This can impact the heart, contribute to premature aging, and impact other wellness factors. As an antioxidant, Kaneka Ubiquinol^® neutralizes free radicals, preventing oxidative stress in the heart and whole body.

Research has shown that supplementing with Kaneka Ubiquinol^® supports cardiovascular function and wellness. It can be especially helpful for adults taking a statin medication to manage cholesterol on their heart health journey, as statin medications can deplete ubiquinol levels in the body. It can also be especially helpful for women undergoing menopause, as post-menopausal women are at a higher susceptibility to oxidative stress, which impacts the heart.

Heart health is relevant at every age. Research shows that factors affecting cardiovascular wellness can begin accumulating in adolescence and young adulthood. The earlier healthy habits are established, the greater their long-term impact.

How can a person support heart health through diet?

A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats supports cardiovascular wellness. Avoid highly processed foods and trans fats as much as possible.

Does emotional stress affect heart health?

Yes. Research has shown that unmanaged, prolonged emotional stress can have measurable effects on cardiovascular function. Managing stress through physical activity, mindfulness, adequate sleep, and social connection supports both mental and cardiovascular wellness.

What role does ubiquinol play in heart health?

Ubiquinol is a naturally occurring nutrient essential for cellular energy production, particularly in the heart. As the active antioxidant form of CoQ10, it helps protect cells against oxidative stress, which impacts cardiovascular function. The body’s ability to produce CoQ10 naturally declines with age, making ubiquinol supplementation increasingly important.
