Review of vitamin complexes to improve memory: a detailed guide for nutrients for cognitive health

Section 1: understanding of memory and cognitive functions

Before delving into vitamin complexes, it is necessary to understand the complex nature of memory and cognitive functions. Memory is not a single entity; It consists of various systems, each of which is responsible for different types of information and processes. Key memory types include:

• Sensory memory: Short -term storage of sensory information (vision, hearing, touch). It lasts only a few seconds.
• Short -term memory (working memory): Temporary storage of information necessary for the performance of tasks. Limited in terms of volume and duration (about 30 seconds without repetition).
• Long -term memory: Storage of information for a long time. Divided into:
  • Explicit (declarative) memory: Conscious recalling of facts and events.
    • Semantic memory: Knowledge of the world, facts, concepts.
    • Episodic memory: Memories of personal events and experiences.
  • Implicit (procedural) memory: Unconscious memorization of skills and habits (cycling, playing a musical instrument).
• Prospective memory: Removing plans and intentions for the future.

Cognitive functions include a wide range of mental processes, such as attention, concentration, speed of information processing, language, solving problems and decision making. All these functions are closely related to memory and interact with it.

Many factors affect cognitive functions and memory:

• Age: With age, a natural decrease in cognitive functions occurs, including memory.
• Genetics: Heredity plays a role in predisposition to cognitive impairment.
• Life: Improper nutrition, lack of physical activity, smoking, alcohol abuse and lack of sleep negatively affect cognitive functions.
• Diseases: Various diseases (depression, anxiety, neurodegenerative diseases) can disrupt memory and cognitive functions.
• Stress: Chronic stress negatively affects the brain and memory.

Section 2: The role of vitamins and minerals in cognitive health

Vitamins and minerals play a vital role in maintaining optimal brain and cognitive functions. They participate in various processes, such as:

• Neurotransmitter production: Neurotransmitters are chemicals that transmit signals between nerve cells. Vitamins and minerals are necessary for the synthesis of these important substances.
• Protection against oxidative stress: Oxidative stress is an imbalance between free radicals and antioxidants that can damage brain cells. Some vitamins and minerals are powerful antioxidants.
• Energy brain metabolism: The brain consumes a huge amount of energy. Vitamins and minerals are involved in processes that provide the brain with energy.
• The structure and function of brain cells: Vitamins and minerals are necessary to maintain the structure and functioning of nerve cells.
• Blood supply to the brain: Some vitamins and minerals contribute to a healthy blood flow in the brain, which is necessary for its optimal work.
