Choline reaches the brain largely as lysophosphatidylcholine (LPC, as it's called), which carries an omega-3 fatty acid. Increasing EPA+DHA increases this LPC flux, which raises delivery of both omega-3s and choline to cortical regions involved in learning and stress adaptation.

Recovery from anxiety requires new learning in cortical circuits. Choline availability influences that process directly Animal + human work agree: • choline scarcity → impaired learning, memory formation, and circuit adaptation • choline sufficiency → enhanced plasticity

New data shows that individuals with anxiety disorders reliably have ~8% lower choline-containing compounds in the cortex. This reduction reflects pressure on three choline-dependent processes: -phospholipid cycling in neuronal and myelin membranes -brain uptake and efflux of

Your spine isn’t just a backbone, it’s your body’s "wiring harness." Your spine isn’t just a stack of bones. It’s the main cable connecting your brain to every organ, muscle, and sensation in your body. Each level of your spine sends out branches (spinal nerves) that control

Stress can reduce cognition (memory, attention) by ~20% (with respect to test scores) Certain botanicals (e.g., Rhodiola, Ashwagandha) may mitigate via HPA-axis regulation and neuroprotection Evidence is promising but requires standardization. As always, act with diet, sleep,
