From the Guidelines
Coenzyme Q10 (CoQ10) supplementation is the most effective way to enhance the efficiency of Complex 2 in the electron transport chain, with a recommended daily dose of 100-200 mg. This is based on the latest evidence from a 2022 systematic review and meta-analysis published in Advances in Nutrition 1, which found that CoQ10 supplementation has a beneficial effect on blood pressure and cardiovascular health. The study suggests that CoQ10 supplementation can enhance antioxidant capacity, improve NO bioavailability, and exert a direct beneficial effect on the endothelium, ultimately leading to improved cellular energy production. Key factors to consider when supplementing with CoQ10 include:
- Taking it with meals to improve absorption
- Maintaining a consistent daily dose
- Combining it with a balanced diet and regular aerobic exercise to stimulate mitochondrial biogenesis and increase Complex II activity
- Avoiding excessive oxidative stress by limiting alcohol consumption and environmental toxin exposure Additionally, other essential components for Complex II activity, such as riboflavin (vitamin B2) and iron, should be maintained at adequate levels through diet or supplements, as supported by the espen micronutrient guideline published in Clinical Nutrition in 2022 1. Overall, CoQ10 supplementation is a crucial component of enhancing Complex II efficiency, and its benefits can be further amplified by adopting a comprehensive approach to mitochondrial health.

From the Research
Enhancing Efficiency of Complex 2 of Electron Transport Chain
The efficiency of Complex 2 (also known as succinate dehydrogenase) in the electron transport chain can be enhanced by several factors, including:
- Proper assembly of the complex: Studies have shown that the assembly of Complex 2 is crucial for its function and efficiency 2, 3.
- Presence of cofactors: The presence of cofactors such as flavin adenine dinucleotide (FAD) is essential for the function of Complex 2 4, 5.
- Covalent binding of FAD: The covalent binding of FAD to Complex 2 is necessary for the conversion of FADH2 into FAD and for the proper arrangement of the active center 5.
- Assembly factors: The presence of assembly factors such as SDHAF2 is necessary for the proper assembly and function of Complex 2 3.
- Protein-mediated assembly: The protein-mediated assembly of Complex 2 is crucial for its function and efficiency, and involves the coordination of multiple subunits and cofactors 2.
Key Factors
Some key factors that enhance the efficiency of Complex 2 include:
- The presence of SDHAF2, which is necessary for the assembly and activity of Complex 2 3.
- The covalent binding of FAD, which is necessary for the proper arrangement of the active center and for the conversion of FADH2 into FAD 5.
- The proper assembly of the complex, which involves the coordination of multiple subunits and cofactors 2.
Mechanisms
The mechanisms by which these factors enhance the efficiency of Complex 2 include:
- The facilitation of electron transfer: The covalent binding of FAD and the presence of assembly factors such as SDHAF2 facilitate electron transfer and enhance the efficiency of Complex 2 4, 5.
- The proper arrangement of the active center: The covalent binding of FAD is necessary for the proper arrangement of the active center and for the conversion of FADH2 into FAD 5.
- The regulation of Complex 2 function: The presence of assembly factors such as SDHAF2 and the covalent binding of FAD regulate Complex 2 function and enhance its efficiency 3, 5.
