“Nothing exists save for atoms and space, all else is conjecture.” – Democritus, 460-370 BCE Through the advancements of scientific inquiry, we have come to recognize that our physical bodies serve as hosts to a vast and intricate ecosystem comprised of microorganisms, collectively known as the human microbiome. This microbiome encompasses bacteria, fungi, viruses, and archaea (unicellular organisms) that inhabit our skin, digestive tract, and other anatomical regions.

They assist in the breakdown and absorption of nutrients, produce essential vitamins and compounds, and edu
