This Brain-Focused Nutrient Supports Cognitive Function & Longevity*
Docosahexaenoic acid (DHA), a key omega‑3 fatty acid, comprises the majority of the brain’s fat and is essential for neuronal membrane integrity, memory, and neuroprotection. Clinical studies link DHA intake to better problem‑solving in infants, improved cognition in school‑age children, and enhanced episodic memory in adults. Health experts recommend 250‑500 mg of combined EPA/DHA daily, with higher doses showing measurable cognitive gains. Regular consumption of fatty fish or high‑quality supplements helps preserve gray‑matter volume and supports cognitive longevity across the lifespan.
Regular Heat Sessions Cut Heart Risk and Mortality
