We hear it all the time: “I’m eating well, I’m working out, but I’m still exhausted. What’s going on?”

In today’s fast-paced, high-pressure world, fatigue has become almost expected — but that doesn’t make it normal. At our executive health clinic in Vancouver, we often find that the true issue isn’t a lack of motivation or effort. It’s something happening on a cellular level — in the mitochondria.

Mitochondria are the energy producers of the body — tiny power plants inside each cell, responsible for creating ATP, the molecule that fuels everything from brain function to muscle movement. When mitochondria are functioning well, you feel sharp, energized, and resilient. But when they’re compromised, even small tasks can feel draining.

In 2025, more people than ever are dealing with the effects of mitochondrial dysfunction, often without realizing it. This shows up as persistent fatigue, brain fog, slower recovery, and even signs of early aging. It’s especially common among high-performing individuals who push themselves hard, but don’t always have time to fully recover or replenish.

Modern stressors take a toll. Poor sleep, environmental toxins, overtraining, chronic psychological stress, and even nutrient-depleting medications all put strain on the mitochondria. Over time, this can result in reduced energy production, more oxidative stress, and cells that don’t repair or regenerate the way they should. And because mitochondria are involved in nearly every organ system — especially the brain, heart, and muscles — their dysfunction doesn’t just cause tiredness. It’s connected to everything from cognitive decline to metabolic slowdowns to inflammation.

This is where functional medicine and targeted therapies come in. Instead of guessing, we test. We look at nutrient levels, mitochondrial markers, and antioxidant status — and from there, create a personalized plan to rebuild and optimize.

One of the most effective ways we support mitochondrial health is through targeted injectable nutrients. Unlike oral supplements, injectables bypass the digestive system and deliver nutrients directly into the bloodstream — ideal for patients with poor absorption, high demands, or chronic deficiencies.

Here’s how we use them in practice:

• L-Carnitine
  Supports the transport of fatty acids into mitochondria, where they’re converted into energy. This is especially helpful for enhancing metabolism, endurance, and recovery.
• CoQ10
  A powerful antioxidant and essential component in ATP production. CoQ10 helps boost cellular energy, while also protecting against oxidative stress and inflammation.
• NAD+
  A critical molecule for mitochondrial repair, DNA integrity, and healthy aging. NAD+ levels naturally decline with age, and restoring them can improve mental clarity, energy, and resilience to stress and fatigue.

These therapies are part of a broader strategy to help our patients feel recharged, focused, and physically strong — from the inside out.

Mitochondrial health is no longer something only researchers and biohackers talk about — it’s becoming a central focus in preventative and performance medicine. When your cells are functioning well, you feel it in every area of life: sharper thinking, better recovery, more stable energy, and a deeper resilience to stress.

If you’ve been feeling like your body isn’t keeping up with your lifestyle — or your lab work is “normal” but you don’t feel like yourself — it may be time to look deeper. In 2025, optimizing your mitochondrial health may be the key to unlocking the next level of your energy, clarity, and longevity.
