Your brain is 60 percent fat. Let that land for a second. And the most important fat up there is DHA — one of the two main omega-3 fatty acids. DHA isn't just helpful for your brain. It is your brain. It makes up a massive proportion of your neuron cell membranes, especially in the areas that handle memory and learning. When DHA is low, your brain cell membranes go stiff. Signals slow down. Communication between neurons breaks down. You experience it as fog. Poor memory. Struggling to learn new things. When DHA is optimal? The opposite. Faster signalling. Less brain inflammation. Better neuroplasticity — your brain's ability to rewire and adapt. Most people aren't getting enough from food. Salmon, mackerel, sardines — three to four times a week would cover it. Be honest with yourself. Are you doing that? Didn't think so. Supplementing is the practical fix. But the form matters — and this is where the supplement industry loves to trick people. Look for triglyceride form fish oil. Not ethyl ester. Triglyceride is the natural form found in actual fish, and your body absorbs it about 70 percent better. The cheap stuff on the shelf? Usually ethyl ester. And check the label for DHA specifically. Not just "total omega-3." You want at least 1000 milligrams of DHA per day. Take it with a meal that has fat in it — absorption goes way up. Now look at the full picture. Magnesium l-threonate for connections. Lion's Mane for growth. Choline for memory chemistry. Omega-3 DHA for brain structure. Four supplements. Four different pathways. Together, they give your brain everything it needs to perform now and protect itself long-term. Let me put it all together for you. The exact doses, the timing, how to take them.
