Biguanide (anti-diabetic) drugs have been found in scientific evidence to decrease serum levels of coenzyme Q10. Type 2 diabetes can increase oxidative stress in the body, weakening its defenses and potentially harming cells. CoQ10, a powerful antioxidant, plays a crucial role in protecting cells from this damage. CoQ10 supplementation may help restore these levels, potentially improving mitochondrial function and protecting the kidneys from damage.

CoQ10 deficiency can present in infancy as a severe encephalomyopathy or multisystemic mitochondrial disease, with features such as hypotonia, developmental delay, intractable seizures, lactic acidosis, cardiomyopathy, and failure to thrive. Reports of infantile‑onset multisystem CoQ10 deficiency describe very early presentations, sometimes in the neonatal period, with rapid neurologic deterioration and involvement of brain, heart, kidney, and liver, and many affected children die in the first months or years of life despite intensive care. The important clinical point is that, although outcomes are often poor in the most severe cases, some infants and young children show neurologic improvement or stabilization when CoQ10 deficiency is recognized early and high‑dose CoQ10 supplementation is started promptly, which is why this diagnosis is considered a treatable cause of infantile encephalomyopathy
CoQ10 is a key mitochondrial antioxidant, and circulating levels are often reduced in people with chronic kidney disease and chronic heart failure, where deficiency is linked to greater oxidative stress and poorer organ function. In CKD cohorts, lower CoQ10 levels correlate with increased cardiovascular risk, and supplementation has been reported to improve markers such as proteinuria, mitochondrial function, and oxidative stress, with some studies suggesting better preservation of kidney function over time. In patients with chronic heart failure, trials such as Q-SYMBIO have shown that CoQ10 supplementation can improve cardiac function parameters and significantly reduce major adverse cardiovascular events, cardiovascular mortality, and heart‑failure–related hospitalizations.
