And yes, anyone depleting CoQ-10 would do wisely to take some.
Watch for any improvements to gauge if it is helping. The most likely obvious thing with CoQ-10 is less fatigue and more stamina as it helps with the heart and muscle energy requirements.
Some people with Parkinson's use very high dose CoQ-10 to help with tremors because those cells may have damaged mitochondria in the brain. Each person will have different responses depending on their own weakness/error in chemstry.

This is why I don't like big combo mixture products for PN.
When several are mixed together in one pill...you cannot tailor your doses to what YOU need. Because all of us are different in what we need.
