Wild Salmon/Sardines (Brain)
DHA is primary structural fat in brain (97% of omega-3s in brain). Supports neuronal membrane fluidity, neurotransmitter production. EPA reduces neuroinflammation. Astaxanthin crosses BBB (antioxidant).
Blueberries (Brain)
Anthocyanins cross BBB and accumulate in hippocampus (memory). Increase BDNF (brain-derived neurotrophic factor). Improve neuronal signaling. Reduce oxidative stress and neuroinflammation.
Eggs (Pastured)
Choline precursor to acetylcholine (memory neurotransmitter). Lutein and zeaxanthin accumulate in brain (processing speed). DHA in yolks. B12 prevents brain atrophy.
