Do you feel drained, even after a full night’s sleep? Fatigue is one of the most common concerns we see in our practice here at Seek Optimal Wellbeing in the Fraser Valley in downtown Chilliwack, BC. While lifestyle factors like poor sleep, stress, and overwork often contribute, one frequently overlooked cause is nutrient deficiencies.

Understanding Fatigue

Fatigue is more than feeling tired—it’s a lack of mental and physical energy that can affect your ability to focus, exercise, and enjoy life. While lifestyle changes can help in some cases, persistent fatigue may indicate an underlying nutritional or medical issue, such as thyroid problems, anemia, or chronic disease.

Nutritional Insufficiencies: A Hidden Culprit

Even in developed countries, many people consume enough food to avoid obvious illness but not enough to support optimal energy production and long-term health. Put simply, we are often overfed and undernourished. This forces the body to prioritize short-term survival over vibrant health, leaving you feeling tired and unmotivated.

Optimizing Your Nutrition

The first step to improving energy is eating a nutrient-dense diet:

  • Plenty of fruits, vegetables, legumes, whole grains, nuts, seeds, eggs, and dairy (if tolerated)

  • Focus on foods rich in B vitamins, vitamin C, iron, magnesium, and zinc

When diet alone isn’t enough, supplements or IV nutrient therapy can help fill the gaps efficiently, providing the nutrients your body needs for energy, mental clarity, and overall wellness.

The Dynamic Dozen

I call these twelve essential nutrients the Dynamic Dozen, critical for supporting your body’s energy production:

  • B Vitamins (B1, B2, B3, B5, B6, B8, B9, B12)

  • Vitamin C

  • Iron, Magnesium, Zinc

Even a shortfall in one of these nutrients can limit energy production, affect metabolism, and reduce stamina, focus, and motivation.

Why Mitochondria Matter

Mitochondria are the powerhouses of your cells, responsible for producing the energy your body needs to function, recover, and repair. Nutrient deficiencies, chronic stress, poor sleep, and environmental toxins can all impair mitochondrial function, leaving you fatigued and at higher risk for chronic disease.

Correcting Nutrient Deficiencies

  • Dietary Sources: Leafy greens, fatty fish, legumes, whole grains, eggs, nuts, seeds

  • Supplements & IV Nutrient Therapy: Useful when diet alone isn’t enough, especially for severe deficiencies or immediate energy support

  • Micronutrient Testing: “Test, don’t guess.” Everyone’s needs are different, so personalized testing ensures optimal results

Key Takeaways

  • Fatigue can stem from nutrient deficiencies, even if you eat “enough” food

  • The Dynamic Dozen nutrients are essential for energy, cognitive function, and overall wellness

Correcting deficiencies through diet, supplements, or IV therapy can restore energy, focus, and vitality
