Nutrients for mitochondrial complexes function

Mitochondrial complexNutrients
ETC complexesCopper, iron, sulfur, riboflavin and ubiquinone coenzyme Q10 (CoQ10)
PDH complexRiboflavin, niacin, thiamin, pantothenic acid and lipoic acid
TCA cycle
  • Iron, sulfur, thiamin, riboflavin, niacin, pantothenic acid, cysteine, magnesium, manganese, and lipoic acid

  • Synthesis of heme for heme-dependent enzymes in the TCA cycle needs various nutrients such as copper, iron, riboflavin, pyridoxine and zinc

  • Synthesis of L-carnitine requires ascorbic acid
