Best Supplements for Brain Fog Without Caffeine (2025 Neurologist Guide)

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.

The Shocking Link Between Sleep Position and Alzheimer's Risk

The Shocking Link Between Sleep Position and Alzheimer's Risk

Recent Yale Medicine research reveals a startling connection between sleep position and Alzheimer's risk. Side sleeping enhances glymphatic clearance by up to 25% compared to back sleeping, significantly improving your brain's ability to remove beta-amyloid proteins associated with Alzheimer's disease. Studies show just two hours of supine (back) sleeping reduces this critical brain-cleaning process, while left-side sleeping optimizes the glymphatic system—your brain's overnight cleaning crew that removes harmful proteins during deep sleep. Dr. Brain Good's 3-step sleep position protocol helps optimize this natural detoxification process to protect against cognitive decline.

Is Your Gut Health Destroying Your Memory?

Is Your Gut Health Destroying Your Memory?

Groundbreaking research from Stanford Medicine reveals the gut-brain connection directly impacts memory function and cognitive performance. Your gut microbiome communicates with your brain through the gut-brain axis, affecting hippocampal health and memory formation. Studies show specific gut bacteria patterns predict memory decline 6-18 months before symptoms appear, while intestinal permeability ("leaky gut") allows inflammatory compounds to damage memory centers. Dr. Brain Good's 14-day gut-memory reset protocol targets these microbiome imbalances to restore cognitive function and prevent further memory decline.
