Why Brain Needs Omega-3 + Protein Together

Your brain relies on both omega-3 foods for brain health and high-protein nutrients to function optimally. Omega-3 fatty acids support neuron structure and ensure smooth neurotransmitter signaling, which keeps your brain alert and focused. Protein provides essential amino acids that help produce serotonin and dopamine, the key chemicals behind mood, motivation, and memory. Together, they form a powerful combo that naturally improves focus, memory, and emotional balance.
