Dietary Sources of CoQ10

Plants produce their own coenzyme Q analogues as part of the photosynthesis system, making dark leafy greens a plant-based CoQ10 source. Chlorophyll is structurally and functionally related to CoQ10, so deeper green color in vegetables signals higher CoQ10-like compound content. Beef heart is the single richest dietary source of CoQ10 because the heart accumulates the most CoQ10 of any organ. Beef liver is the second-best organ meat source of CoQ10. Fish with red flesh contain more CoQ10 than white-fleshed varieties, with yellowfin tuna highlighted as a particularly good source. Parsley is particularly high in CoQ10-like compounds among plant sources. Blue-green algae such as spirulina and chlorella are rich in chlorophyll and represent a plant-based source of CoQ10-supporting compounds.
