Brain & Memory

Brain health and cognitive function are essential for maintaining independence, quality of life, and daily functioning throughout the lifespan. The human brain, comprising approximately 100 billion neurons, is the most metabolically active organ in the body, consuming about 20% of the body's total energy despite representing only 2% of body weight. Cognitive functions including memory, attention, processing speed, executive function, and learning depend on optimal brain structure and function.

Cognitive decline and neurodegenerative conditions represent growing global health challenges. Alzheimer's disease, the most common cause of dementia, affects over 55 million people worldwide. Mild cognitive impairment (MCI), Parkinson's disease, vascular dementia, and other neurological conditions impact millions more. Age-related cognitive decline, even in the absence of dementia, can significantly affect quality of life. Risk factors include aging, genetics, vascular disease, diabetes, head trauma, depression, and modifiable lifestyle factors.

The brain requires specific nutrients for neurotransmitter synthesis, myelin formation, membrane integrity, energy metabolism, and neuroprotection against oxidative stress and inflammation. Nutritional deficiencies can impair cognitive performance, while optimal nutrition may slow cognitive decline and support brain resilience. Critical periods including fetal development, early childhood, and older adulthood have particularly high nutritional requirements for brain health. Evidence suggests that nutritional interventions may help preserve cognitive function and support brain health across the lifespan.
