Who should not take CoQ10?

Individuals who are pregnant or breastfeeding should avoid taking CoQ10 due to limited safety data. Additionally, those on blood-thinning medications, such as warfarin, should consult their healthcare provider before starting CoQ10, as it may affect blood clotting. People with certain medical conditions, such as liver or kidney disease, should also seek medical advice prior to use. Always consult a healthcare professional for personalized recommendations.
