Critical nutrients for brain health include omega-3 fatty acids, particularly DHA, which supports cognitive function and neuronal health. Antioxidants such as vitamin E and C protect neural cells from damage. B vitamins, especially B6, B12, and folate, are essential for neurotransmitter function. Adequate intake of minerals like magnesium and zinc is vital for synaptic plasticity. Focusing on a well-rounded diet rich in these nutrients promotes neuronal growth and supports overall brain function.
