Five Vitamins for Brain Health and Memory

Introduction 

Maintaining brain health throughout the lifespan is essential for healthy aging, optimal cognitive function, and overall quality of life. The brain plays a central role in how we think, learn, remember, regulate emotions, and interact socially, making cognitive integrity fundamental to daily functioning. Cognitive impairment can significantly disrupt these processes. (Li 2025) While some contributors to cognitive decline may be outside an individual’s control, such as traumatic brain injury or genetic predisposition, many other risk factors are modifiable. (National Institute on Aging 2024) For example, nutritional status has emerged as an important area of intervention. Growing scientific interest has focused on the role of diet and targeted nutrients, including vitamins for brain health, in supporting cognitive performance and reducing the risk of age-related decline.

The brain and nervous system are responsible for many cognitive functions, including attention, memory, information processing, and higher-level skills called executive functions. (Johnson 2013) Cognitive impairment, commonly measured by standardized tests, refers to alterations in cognitive performance that exceed what is considered normal for healthy aging. (Anand 2024) A range of changes to cognitive functions may precede clinical dementia, a neurodegenerative condition characterized by global cognitive decline and a variety of symptoms, such as memory loss and impaired communication, recognition, and judgment.
