Natural dietary supplements to stimulate brain activity

Part 1: Basics of brain activity and factors affecting cognitive functions

The human brain is a complex organ responsible for thinking, memory, attention, speech, training and many other vital functions. Optimal brain activity is extremely important for productivity, creativity, general well -being and quality of life. However, numerous factors can affect cognitive functions, both positive and negative.

1.1. Neurobiological foundations of cognitive functions:

Understanding the basic principles of brain function is necessary for a conscious choice of dietary supplements. Key aspects include:

Neurotransmitter: Chemicals transmitting signals between neurons. The most important for cognitive activity:
- Acetylcholine: Participates in training, memory and attention.
- Dofamine: Associated with motivation, pleasure, reward and attention.
- Serotonin: Regulates mood, sleep, appetite and cognitive functions.
- Norepinephrine: It affects vigilance, concentration and stress reaction.
- Gamma-aminobral acid (GABA): Inhibitory neurotransmitter, soothing the nervous system and reducing anxiety.
- Glutamate: The main exciting neurotransmitter, important for training and memory.
Neuroplasticity: The ability of the brain to adapt and rebuild in response to new experience and training. Optimization of neuroplasticity is critical of maintaining cognitive function throughout life.
Neurogenesis: The process of the formation of new neurons, especially in the hippocampus (the area of the brain responsible for memory). Support for neurogenesis helps to improve memory and learning.
Brain bloodstream: Adequate blood supply to the brain is necessary to provide neurons with oxygen and nutrients. Improving blood flow helps to increase cognitive function.
Myelination: The process of formation of the myelin shell around the axons of neurons, accelerating the transmission of nerve impulses. Optimal myelinization increases the effectiveness of the brain.

1.2. Factors that negatively affect cognitive functions:

Many factors can worsen cognitive functions, including:

Age: With age, a natural decrease in cognitive function occurs, including worsening memory, attention and speed of information processing.
Stress: Chronic stress can damage the brain, reduce cognitive functions and increase the risk of developing neurodegenerative diseases.
Lack of sleep: Lack of sleep negatively affects memory, attention, concentration and ability to learn.
Inal meals: The deficiency of certain nutrients, such as omega-3 fatty acids, B vitamins and antioxidants, can worsen cognitive function. Excess sugar and processed products is also harmful.
Lack of physical activity: Low physical activity reduces cerebral blood flow and worsens cognitive functions.
Chronic diseases: Some diseases, such as diabetes, hypertension and cardiovascular diseases, can negatively affect cognitive functions.
Toxins: The effects of toxins, such as heavy metals and pesticides, can damage the brain and reduce cognitive functions.
Neurodegenerative diseases: Alzheimer’s disease, Parkinson’s disease and other neurodegenerative diseases lead to a progressive decrease in cognitive function.
Alcohol abuse and drugs: Excessive drinking of alcohol and drugs can damage the brain and reduce cognitive functions.

1.3. Factors that positively affect cognitive functions:

You can improve cognitive functions due to the following factors:

Balanced nutrition: The use of products rich in nutrients necessary for the health of the brain.
Regular physical activity: Physical exercises improve brain bloodstream, contribute to neurogenesis and improve cognitive functions.
Sufficient sleep: Providing a sufficient amount of sleep to restore and consolidate memory.
Stress management: The use of stress management techniques, such as meditation, yoga and deep breathing.
Cognitive exercises: Regular performance of cognitive exercises, such as puzzles, crosswords and the study of new skills.
Social activity: Maintaining active social life, communication with friends and family.
Training throughout life: Constant training and acquisition of new knowledge.
Reception of dietary supplements to stimulate brain activity: The use of natural dietary supplements to support and improve cognitive functions.
