Best Supplements for Brain Fog Without Caffeine (2025 Neurologist Guide)
Recent clinical studies reveal that caffeine-free brain fog supplements work through three key mechanisms: reducing neuroinflammation, supporting mitochondrial function, and enhancing neurotransmitter balance. Lion's mane mushroom demonstrates significant cognitive improvements through nerve growth factor stimulation, while magnesium L-threonate uniquely crosses the blood-brain barrier to support synaptic plasticity. Omega-3 DHA reduces inflammatory markers by up to 23% in brain fog patients, and rhodiola rosea adapts cortisol response for sustained mental energy without stimulant crashes.
