Can CoQ10 cure my dog's heart disease?

No. CoQ10 is formulated to support cardiovascular and cellular health, not to cure or treat heart disease. Always follow your vet's treatment plan for a diagnosed condition.

Is this flavored?

No, the capsules are unflavored, so some owners hide them in food or a treat.

How many capsules come in a bottle?

Each bottle contains 60 capsules.
