The fat soluble vitamins - retinol (vit A) activates steroidogenesis and thyroid conversion, vitamin D supports testosterone and muscle, vitamin E protects mitochondrial membranes (and great for skin and hair) and K2 helps direct calcium into bone.
Choline, which egg yolks are one of the richest sources of, is the direct precursor to acetylcholine, the neurotransmitter governing focus, sustained attention, memory and mind muscle connection. It also supports mitochondrial membrane integrity and liver fat metabolism.
DHA improves neuronal membrane fluidity, which helps with cognition and mental performance.
The heat sensitive intact B vitamins provide critical cofactors and nutrients for mitochondrial energy production.
If you do drink the egg white also, it contains some beneficial gut compounds such as ovotransferrin - belonging to the same protein family as lactoferrin, binding iron starving pathogenic gut bacteria of their primary growth substrate while supporting mucosal immunity and integrity.
