What does Mitochondrial Health Have to Do With Heart Health?

You probably learned about the mitochondria in grade school, but most adults don’t give the mitochondria much thought on a daily basis. You might know that mitochondrial health is critical to your overall well-being, but the truth is: it has a foundational role in supporting your heart. The active antioxidant form of CoQ10, ubiquinol, plays a foundational role in heart health, as it supports the mitochondria in doing their important cellular jobs, especially in major organs.

If you’ve noticed more content about the connection between heart and mitochondrial health on the Kaneka site, that’s no coincidence. Well-established and new research highlights how ubiquinol supports cellular energy and mitochondrial health. You’ll see more resources on this topic going forward — but rest assured, Kaneka Ubiquinol® still plays a vital role in supporting your heart health and overall wellness. This shift simply reflects a broader understanding that has emerged of how ubiquinol benefits your body at the cellular level.

Understanding Your Heart on a Cellular Level

Understanding the mitochondria’s importance to heart health means exploring how the heart functions. Mitochondria are everywhere in the body, but they are especially abundant in the heart, given the organ’s high energy requirement. Did you know that each heart muscle cell contains up to 8,000 mitochondria, while a less energy-demanding cell may contain 1,000 or fewer?1 As important players in producing cellular energy, the mitochondria actually produce most of the ATP — the “energy currency” of cells — used in the heart’s muscular tissue, making it critical for cellular, heart, and overall function.

The link between the mitochondria and heart is not complicated: healthy mitochondria support overall heart health and function, especially as you age. There are several key ways to protect your heart health, including through a nutritious diet, routine exercise, regular screenings, and stress management. Yet, understanding how your heart works on a cellular level — and supporting it with supplementation — is sometimes an overlooked piece to the puzzle.

Ubiquinol: A Foundation of Healthy Heart Function

The mitochondria are foundational to cardiovascular health and overall well-being, but they rely on the support of ubiquinol — a naturally occurring antioxidant in the body. As we age, ubiquinol’s support becomes even more important to protect our cells from the effects of aging, but after age 40, our bodies also have a harder time producing this vital antioxidant.

Why Your Heart Has So Many Mitochondria

Commonly known as the powerhouse of the cell, the mitochondria are better understood as the “CEO of the cell” because they do so much more than power the cell: they drive many critical maintenance and management jobs of your cells. The heart contains a high number of mitochondria to fill the energy demand of heart cells, and ubiquinol’s antioxidant properties are essential for vital cellular functions, like producing energy, defending against cell damage from oxidative stress, and supporting new cell generation. As we get older, our bodies don’t produce this important antioxidant as efficiently, which may contribute to premature aging. But here’s the good news: a daily Kaneka Ubiquiniol® supplement provides antioxidant support to your vital organs and supports your healthy aging journey.2

Ubiquinol and Cellular Maintenance: What to Know

As the “CEO of the cell,” the mitochondria do more than just support heart health and healthy aging. Ubiquinol plays a role in functions of cellular homeostasis, or “facility maintenance,” which are managed by the mitochondria. Below are a few of the ways ubiquinol promotes mitochondrial function so they can perform as the “CEO”:

  • Plays a key role in mitochondrial homeostasis
  • Promotes healthy mitochondrial biogenesis
  • Maintains mitochondrial membrane integrity
  • Supports critical maintenance functions such as: fission and fusion, apoptosis, mitophagy, and senescence

Knowing ubiquinol’s significance to your heart and overall health helps you understand the benefits of taking a daily Kaneka Ubiquinol® supplement, no matter your adult life stage.

Healthy Heart = Happy Aging

Aging is a normal process, but that doesn’t mean you should overlook lifestyle changes that help you feel and live your best. While ubiquinol supports healthy aging and protects against cellular damage caused by free radicals, be sure you also consider Kaneka’s six tips for keeping your heart healthy over time:

  • Eat a nutritious diet
  • Stay active
  • Track your heart health metrics
  • Manage stress
  • Get regular check-ups
  • Make heart health a lifestyle choice

Promoting a healthy heart is a lifestyle, not a one-time fix. Knowing that small, simple choices over time impact long-term well-being makes building everyday habits that much easier.

Kaneka Helps You Support Your Heart and Mitochondrial Health

The heart relies on the mitochondria, and both rely on ubiquinol. You’ll likely see much more mitochondrial health content from us going forward, as Kaneka supports this exciting new space. Be on the lookout for upcoming information on the site about how mitochondrial health and heart health work together, and check out the clinical studies page to read more about studies using Kaneka Ubiquinol® demonstrating a range of health benefits.

Remember: you can support your heart health in a number of ways (see our heart health checklist for ideas), but talk to your doctor about how a Kaneka Ubiquinol® supplement can support your heart-healthy lifestyle.
