Coenzyme Q10 supplementation raises plasma levels without improving mitochondrial function in older adults

Key Points

• Plasma levels of coenzyme Q10 increased significantly after supplementation, but mitochondrial function remained unchanged.
• Participants saw a notable rise in coenzyme Q10 levels, but the expected improvements in mitochondrial operations did not occur.
• This analysis involved older adults taking coenzyme Q10 supplements, evaluating both plasma levels and mitochondrial activity.
• These findings indicate that while supplementation raises coenzyme Q10 in plasma, it may not impact mitochondrial health significantly.
