CoQ10 is unrelated to the liver function, AFAIK.
I take it, but for general mitochondrial cellular depletion, and the myopathies that can follow, not as a liver “fix-up”.
If anyone is aware of a peer-reviewed study suggesting the contrary, please PM me.
Liver function can be adversely impacted by statins for sure, but I know of nothing to suggest that CoQ10 is a factor there.
