Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant that plays a vital role in cellular energy production within the mitochondria. Every cell in your body depends on CoQ10, but the heart, liver, and kidneys have the highest concentrations. Statin medications are known to deplete CoQ10 levels, which may contribute to the muscle pain and fatigue some statin users experience. Monitoring CoQ10 is recommended for statin users, individuals with heart failure, and those with chronic fatigue.
Vitamin and nutrient testing identifies deficiencies that can drive fatigue, immune dysfunction, neurological symptoms, and long-term disease risk — and confirms that supplementation is working.
Anyone with restrictive diets (vegan, low-fat, low-carb), malabsorption conditions, fatigue, hair loss, mood changes, or currently supplementing and wanting to verify dosing.
