Omega-3 for the brain: which additives to choose

Omega-3 for the brain: which additives to choose

I. The role of omega-3 fatty acids in brain health

Omega-3 fatty acids, in particular eicophantamentenic acid (EPA) and daily oxaenic acid (DHA), play a key role in maintaining health and optimal function of the brain throughout life. These irreplaceable fats that the body cannot synthesize independently must be obtained from food or additives.

A. Structural function and neural membranes:

• Dha as a building block: DHA is the main structural component of the cell membranes of the brain, especially in the gray matter that is responsible for cognitive functions. It accounts for up to 97% of all omega-3 fatty acids in the brain and about 25% of the total content of fats in the brain.
• Flexibility and fluidity of membranes: DHA increases the flexibility and fluidity of neural membranes. This is critically important for effective neurotransmission, as it provides optimal functioning of receptors and ion channels. More flexible membranes contribute to a faster and more effective transmission of signals between neurons.
• Impact of Sinapogenes: DHA plays a role in synaptogenesis, the process of forming new synapses — compounds between neurons. This process is important for learning, memory and a common cognitive function. A sufficient amount of DHA supports the formation and maintenance of healthy synaptic connections.
• Protection against oxidative stress: Membrane, rich DHA, are more vulnerable to oxidative stress. However, DHA also stimulates the production of antioxidants, helping to protect the brain from damage caused by free radicals.
• Regulation of genetic expression: DHA can affect the expression of genes involved in the development of the brain, neurogenesis and synaptic plasticity. This suggests that DHA can have a long -term effect on the structure and function of the brain.

B. Influence on neurotransmission:

• Serotonin: Omega-3 fatty acids, especially EPA, can affect the level of serotonin in the brain. Serotonin is a neurotransmitter that regulates mood, sleep, appetite and social behavior. Studies show that EPA can enhance the release of serotonin and increase the sensitivity of serotonin receptors.
• Dofamine: Omega-3 fatty acids can also affect the dopamine system of the brain. Dopamine is associated with motivation, pleasure and attention. Omega-3 deficiency can violate the dopamine neurotransmissance, which leads to a decrease in motivation and concentration.
• Acetylcholine: DHA plays a role in maintaining the health of cholinergic neurons, which use acetylcholine as a neurotransmitter. Acetylcholine is important for memory, learning and attention. A decrease in the level of acetylcholine is associated with the cognitive decline and disease of Alzheimer.
• Glutamate: Omega-3 fatty acids can modulate the activity of glutamate, the main exciting neurotransmitter in the brain. Excess glutamate can lead to exeitotoxicity, damage to neurons. Omega-3 helps to maintain a glutamate balance and prevent neurons damage.
• Gamk (gamma-aminobral acid): GABA is the main brake neurotransmitter in the brain. Omega-3 fatty acids can affect the activity of the GABA, helping to reduce anxiety and improve sleep.

C. Anti -inflammatory properties:

• Reducing neuro. Chronic inflammation in the brain is associated with the development of many neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. Omega-3 fatty acids have powerful anti-inflammatory properties that help reduce neuro-drilling.
• Cytokine regulation: Omega-3 fatty acids regulate the production of cytokines, inflammatory molecules, which play a key role in the development of neo-spasm. EPA and DHA contribute to a decrease in the level of pro-inflammatory cytokines, such as Interlayykin-6 (IL-6) and the Alpha tumor necrosis factor (TNF-α).
• Activation of resolvines and protectinations: Omega-3 fatty acids are the predecessors of resolvines and protectins, specialized perishable mediators (SPM), which are actively involved in resolving inflammation and restoration of tissues. These molecules help return the brain to a state of homeostasis after an inflammatory episode.
• Support for microglia: Microlytes are immune brain cells that play a role in removing cell waste and maintaining the health of neurons. Omega-3 fatty acids can modulate the activity of microglia, preventing their excessive activation and contributing to their transition to anti-inflammatory state.
• Protection of the hematoencephalic barrier: The hematoencephalic barrier (GEB) protects the brain from harmful substances in the blood. Inflammation can violate the integrity of the GEB, allowing inflammatory molecules to penetrate the brain. Omega-3 fatty acids help maintain the integrity of the GEB, preventing the penetration of inflammatory substances into the brain.

D. Neuroprotective action:

• Protection against oxidative stress: Oxidizing stress caused by free radicals is one of the main causes of neurons damage. Omega-3 fatty acids have antioxidant properties and contribute to the production of endogenous antioxidants, protecting the brain from oxidative stress.
• Improving blood supply to the brain: Omega-3 fatty acids can improve the blood supply to the brain, contributing to the expansion of blood vessels and a decrease in blood viscosity. Improved blood supply provides the brain with the necessary oxygen and nutrients, maintaining its function.
• Neurogenesis stimulation: Neurogenesis is the process of the formation of new neurons in the brain. Omega-3 fatty acids can stimulate neurogenesis, especially in hippocampus, a brain area associated with learning and memory.
• Decrease in apoptosis (programmable death of cells): Omega-3 fatty acids can protect neurons from apoptosis, programmable death of cells. They help maintain the viability of neurons and prevent their degeneration.
• BDNF modulation (neurotrophic factor of the brain): BDNF plays a key role in the survival, growth and differentiation of neurons. Omega-3 fatty acids can increase the BDNF level in the brain, contributing to its health and functioning.

II. The benefits of omega-3 for various age groups and conditions

Omega-3 fatty acids have a beneficial effect on the brain in different age groups and in various conditions, from intrauterine development to the elderly.

A. Pregnancy and fetal development:
