Unlike some nutrition queries that are somewhat gray and equivocal in nature, when vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol) go head-to-head, the winner is clear. Allow me to use an analogy to explain. To wrap my Olympics nutrition visual: Vitamin D3 is on the middle podium with its anthem playing loud and clear, whereas vitamin D2 didn’t medal at all.

Integrative neurologist Romie Mushtaq, M.D., explains further: “Episodic memory is your unique ability to remember your emotions and experiences around a specific event or situation in your life.

It’s such a buzzword that I imagine many of us blow right past it, but resilience is the real key to understanding the foundation for a healthy immune system.
