Compares the two forms of CoQ10, covering why conversion efficiency declines with age and which form makes more sense for different age groups.

Covers iron deficiency without anemia, why ferritin reference ranges can miss it, and the specific signs to watch for beyond simple fatigue.

Covers B1, B2, B12, iron and CoQ10 for energy through cellular metabolism rather than stimulation, with realistic expectations for who benefits most.
