Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant found in most human cells, where it plays a key role in mitochondrial energy production. Its use for supporting or treating poor circulation is based on both its physiological role and several clinical studies, though the evidence is moderate rather than robust. CoQ10 has been studied primarily in the context of cardiovascular health, particularly in conditions such as heart failure, hypertension, and endothelial dysfunction—all of which are related to circulatory health. Some studies suggest that CoQ10 supplementation can improve endothelial function, which is crucial for healthy blood flow, by enhancing nitric oxide availability and reducing oxidative stress in blood vessels. Meta-analyses have demonstrated modest improvements in blood pressure and vascular function with CoQ10 supplementation. However, direct evidence for its efficacy in treating "poor circulation" as a generalized condition is limited, as most research focuses on specific cardiovascular diseases. The conventional use of CoQ10 for circulation is therefore extrapolated from its effects on cardiovascular endpoints. While CoQ10 is generally well-tolerated and considered safe, more high-quality, targeted studies are needed to establish its effectiveness for poor circulation specifically. In summary, CoQ10’s use for circulation is scientifically plausible and supported by some clinical research, but the strength of evidence is moderate, meriting a rating of 2 out of 5.
