Lysoveta is a one-of-a-kind omega-3 supplement featuring specialized lyso-DHA, a form of DHA with preferential transport into the brain. Research shows that this unique form significantly increases brain DHA levels—much more effectively than conventional fish oils, which are more likely to accumulate in fat tissue.
For a deeper dive into the science, see the letter below.

Nick Note: I understand this is a premium product and may not be accessible to everyone. Still, it’s the one I personally use and trust. I’d feel remiss not recommending it—especially for those concerned with long-term brain health, including ApoE4 carriers.

New human research suggests the real damage of junk food goes far beyond calories or short-term weight gain.
In a controlled trial published in Nature Metabolism, healthy young men overate junk food for just five days — with no meaningful weight gain. Yet beneath the surface, something far more concerning happened: liver fat increased sharply, blood flow to key brain regions dropped, and the brain developed insulin resistance that persisted even after normal eating resumed.
These changes affect areas involved in memory, impulse control, and appetite regulation, creating what researchers describe as prolonged effects on the brain that outlast the binge itself. In other words, short-term junk food intake may leave a metabolic “scar” that makes future overeating more likely.
This video breaks down the study, explains why calories alone don’t tell the full story, and shows how food quality shapes communication between organs like the liver and the brain. Nutrition isn’t simple arithmetic — it’s a complex biological conversation.
