Functional testing looks beyond how much of a nutrient is floating in your blood and asks whether that nutrient is actually doing its job inside the cell. This clip explains how enzyme activity and metabolic byproducts can reveal where key biochemical processes are slowing down, and how those patterns can point toward missing nutrient co-factors.

Orthomolecular medicine starts with a different question: could chronic disease be driven by problems in how the body uses nutrients? This clip explains how vitamins, minerals, and nutrient co-factors fit into this model, and how it differs from a pharmaceutical approach focused primarily on managing symptoms or altering biochemical pathways with drugs.

Mold exposure may interfere with thiamine in more than one way. This clip explores how certain mycotoxins may directly affect B1, while mold-related neuroinflammation can also disrupt thiamine chemistry downstream. It also looks at reports of improved brain function from lipid-soluble thiamine derivatives, even in people still dealing with mold exposure.
