Don't Take Omega-3s Until You Know This | Dr Nick Norwitz

He carried two copies of ApoE4, the highest genetic risk factor for Alzheimer's disease, went through medical school knowing exactly what his LDL of 700 meant, decided the experts were wrong, and then published the case report to prove it. In this episode, Louisa sits down with Dr. Nick Norwitz, PhD researcher and metabolic scientist, for one of the most scientifically dense conversations on brain health, cholesterol biology, and Alzheimer's prevention ever recorded on this show. They cover why the phospholipid form of DHA reaches the brain more effectively than standard fish oil, how ApoE4 carriers burn through omega-3s differently and what to do about it, the lithium orotate data that sold out supplement shelves worldwide, and why GSK-3 beta, the enzyme that phosphorylates tau, may be the most under appreciated target in Alzheimer's research today.

Then Nick lays out the case that challenges the "LDL is always the enemy" consensus: why metabolically healthy individuals may not benefit from aggressive lipid-lowering therapy, what his viral coronary CT angiogram showed after seven years of 700+ cholesterol, why the EZPAVE trial headlines don't hold up under scrutiny, and what GLP-1s are doing inside the brain completely independent of weight loss. You'll also hear about the sardine diet experiment, the omega-3 thermogenesis connection, ketones as misfolded protein clearance agents, creatine for depression, retatrutide and PCSK9, BPC-157 risks, and what Nick believes is coming in Alzheimer's gene therapy within the next decade.
