  Co-enzyme Q10 is found in a wide variety of healthy foods, including fish and whole grains. According to the University of Maryland Medical Center, co-enzyme Q10 has an antioxidant effect on the body. Enzymes improve cell energy and antioxidants protect cells from free radical damage. Free radicals are unpaired molecules that damage tissues and cells. Eating foods rich in co-enzyme Q10 can boost your energy level in addition to raising your immunity.
  
  

Salmon

  The University of Maryland Medical Center lists salmon as a good source of co-enzyme Q10. This food is also high in omega-3 fats, vitamins A and E and protein. Bake or steam your fish so that it maintains nutrient quality. Frying foods can kill nutrients and add unhealthy fats to the food. When baking your fish, use healthy oils such as olive or grape seed oil. Add herbs and lemon juice to enhance the flavor. "Women's Health" magazine states that wild caught Atlantic King salmon is the healthiest type of salmon because farm raised salmon may contain PCB chemicals from polluted waters.
  
  

Organ Meats

• Organ meats such as the hearts and livers of cows, bison, deer and chicken are high in co-enzyme Q10. Like salmon, avoid frying these meats, which reduces the level of co-enzyme Q10. However, this type of food is not a good option for everyone because these meats present both risks and benefits depending on certain health factors such as heart disease. Both Brown University and Medline Plus recommend limiting consumption of organ meat if you suffer from heart conditions.
  
  

Small Fish

• Sardines and mackerel are also high in co-enzyme Q10. The strong salty taste isn't may not be for everyone, but these fish are high in fat and calories. One tiny fish may contain as much as 25 calories. Both sardines and mackerel are also a rich source of omega-3 fatty acids.
  
  

Eggs

  Eggs provide the body with a wide assortment of nutrients, including co-enzyme Q10. Eggs are high in protein, omega-3 fats and vitamin E as well. If you hard boil them, eat the yolk as well because this part contains the highest levels of nutrients.
