Answer:

Levels of CoQ10 in the blood actually increase from young adulthood through middle age, peaking at around age 60, at which time levels begin to slightly decrease. Meanwhile, CoQ10 levels in brain and heart tissue do decrease with age. However, perhaps of more importance, after age 60 less CoQ10 gets converted in the body into its active form, ubiquinol. This is discussed in the What It Is section of the CoQ10 and Ubiquinol Supplements Review, which includes our Top Picks among for CoQ10 and ubiquinol.

Also note that statins, and certain other medications, may decrease your natural production of CoQ10. More about this is found in the Cautions and Concerns section of the Review.

I took one dose of CoQ10 and it made me drowsy. I did not feel well at all. Haven't taken it since.

For what it's worth, I have to take 1200 to 1500 mg liquid ubiquinol daily. I feel good at 1000 mg, but testing showed that I was deficient at 1000! At 500 mg, I get VERY breathless. So maybe you need more than 400 mg for whatever you need it for??
