Pantethine is a derivative of vitamin B5 (pantothenic acid) and serves as a precursor to coenzyme A (CoA), a vital molecule in cellular energy metabolism, particularly within the mitochondria. CoA is essential for the Krebs cycle (citric acid cycle), which is the central process by which mitochondria generate ATP, the cell's primary energy currency. The rationale for pantethine supplementation to support mitochondrial function is based on its biochemical role in CoA synthesis and energy metabolism.

However, while the metabolic pathway is well-characterized, direct clinical evidence that pantethine supplementation enhances mitochondrial function in healthy individuals is limited. Most human studies on pantethine have focused on its effects on lipid metabolism and cholesterol levels, with only a few animal or in vitro studies exploring its impact on mitochondrial health or energy production. Some preclinical studies suggest pantethine may help protect mitochondria from oxidative stress or improve mitochondrial bioenergetics under certain conditions, but these findings have not been robustly validated in large, well-controlled human trials.

In summary, there is a plausible scientific rationale for pantethine's role in mitochondrial health, derived from its involvement in CoA synthesis and energy metabolism. However, direct clinical evidence supporting its supplementation specifically for mitochondrial support is limited, justifying a moderate evidence rating.
