Omega-3 to improve mood and combat depression: detailed analysis

I. Understanding depression and mood disorders

Depression, or a large depressive disorder, is a common, but serious disease that negatively affects how a person feels, thinks and acts. It is characterized by a constant feeling of sadness, a loss of interest in classes that used to bring pleasure, and can lead to various physical and emotional problems. It is important to understand that depression is not just a bad mood or temporary sadness; This is a complex condition that requires an integrated approach to treatment.

IA types of depressive disorders:

There are several types of depressive disorders, each of which has its own characteristics and requires an individual approach:

Great depressive disorder (BDR): This is the most common type of depression, characterized by at least five of the nine main symptoms of depression (listed below) for at least two weeks.
Dystymia (persistent depressive disorder): This is a chronic form of depression in which symptoms are less pronounced than under the BDR, but last at least two years in adults and one year in children and adolescents.
Seasonal affective disorder (SAR): This type of depression is associated with a change in the seasons and usually begins in autumn or winter, when there is less sunlight.
Postpartum depression: Depression that occurs in women after childbirth is often associated with hormonal changes and stress related to child care.
Bipolar disorder (manic-depressive psychosis): Although bipolar disorder is not a purely depressive disorder, it includes depression episodes alternating with mania episodes (high mood and increased activity).
Premenstrual dysphoric disorder (PMDR): The severe form of premenstrual syndrome (PMS), causing significant emotional and physical symptoms for a week or two before menstruation.
Depression caused by the use of psychoactive substances or drugs: Depressive symptoms caused by drug use, alcohol or certain drugs.
Depression associated with another medical condition: Depression caused by chronic diseases such as heart disease, cancer, HIV/AIDS, Parkinson’s disease, etc.

IB symptoms of depression:

Symptoms of depression can vary from person to person, but usually include:

A constant feeling of sadness, longing or voids: The predominant feeling of sadness, which does not pass over time.
Loss of interest or pleasure from classes that used to bring joy: Reducing or complete lack of interest in a hobby, communicating with friends and other classes.

Thoughts about death or suicide: Constant thoughts about death, suicidal thoughts or attempts of suicide.
Physical symptoms, such as headaches, abdominal pain or other inexplicable pains: Depression can also manifest by physical symptoms that do not have a clear cause.

IC factors contributing to the development of depression:

The development of depression is a complex process due to the interaction of various factors:

Genetic predisposition: The presence of depression in a family history increases the risk of developing this disease.
Biochemical factors: The imbalance of neurotransmitters in the brain, such as serotonin, dopamine and norepinephrine, can play a role in the development of depression.
Stress life events: Traumatic events, such as the loss of a loved one, divorce, financial problems or abuse, can provoke the development of depression.
Chronic diseases: The presence of chronic diseases, such as heart disease, cancer or diabetes, can increase the risk of depression.
The use of psychoactive substances: Alcohol abuse or drugs can lead to the development of depression.
Personal features: Some personal characteristics, such as low self -esteem, pessimism and tendency to self -criticism, can increase the risk of depression.
Hormonal changes: Hormonal changes associated with pregnancy, postpartum period, menopause or thyroid diseases can contribute to the development of depression.
Seasonal changes: The lack of sunlight in the winter months can cause seasonal affective disorder (SAR).
Social isolation: The lack of social support and a sense of belonging can increase the risk of depression.

II. Omega-3 fatty acids: basics and advantages

Omega-3 fatty acids is a group of polyunsaturated fatty acids necessary for the normal functioning of the body. They are not produced by the body on their own and should come with food or additives. There are three main types of omega-3 fatty acids: alpha-linolenic acid (ALK), eikosapendaenoic acid (EPK) and non-zahyxenoic acid (DHG).

II.A. Types of omega-3 fatty acids:

Alpha-linolenic acid (Alk): Alc is a plant omega-3 fatty acid contained in foods such as linseed seeds, chia, walnuts and soy oil. ALK can be transformed into EPC and DGC in the body, but this process is ineffective, and only a small part of the Alc is converted into these more important fatty acids.
Eicosapentaenic acid (EPA): EPC is found in fatty fish, such as salmon, mackerel and herring, as well as in additions with fish oil and algae. EPC has anti-inflammatory properties and can have a positive effect on the cardiovascular system and mood.
Docosahexaenic acid (DHA): DHC is also contained in fatty fish and additives with fish oil and algae. DGC is the main structural component of the brain and retina of the eye and plays an important role in the development of the brain, cognitive functions and vision.

II.B. Sources of omega-3 fatty acids:

Fat fish: Salmon, mackerel, herring, tuna, sardines and anchovies are excellent sources of EPK and DGK. It is recommended to consume fatty fish at least twice a week.
Vegetable oils: Flue oil, chia, soy oil and walnut oil contain Alk.
Nuts and seeds: Walnuts, chia seeds and linen seeds also contain Alk.
Enriched products: Some products, such as eggs, milk and yogurt, are enriched with omega-3 fatty acids.
Supplements: Fish oil, krill oil and algae oil are popular additives containing EPK and DGK.

II.C. Advantages of omega-3 fatty acids for health:

Omega-3 fatty acids have a wide range of health benefits, including:

Health of the cardiovascular system: Reducing the level of triglycerides, blood pressure and risk of heart disease.
Brain health: Improving cognitive functions, memory and mood, as well as a decrease in the risk of developing dementia and Alzheimer’s disease.
Eye health: Maintaining the health of the retina and reducing the risk of developing age -related macular degeneration.
Anti -inflammatory action: A decrease in inflammation in the body, which can help with diseases such as arthritis and inflammatory intestinal diseases.
Support for the immune system: Improving the function of the immune system and reducing the risk of infections.
Skin health: Improving the condition of the skin, reducing dryness and inflammation.
Bone health: Strengthening bones and reducing the risk of osteoporosis.

III. The role of omega-3 in the regulation of mood and treatment of depression

Omega-3 fatty acids play an important role in the regulation of mood and can be useful in the treatment of depression. Studies show that people with depression often have a lower level of omega-3 fatty acids in the blood, especially the EPC and DGK.

III.A. Omega-3 action mechanisms for depression:

The mechanisms with which omega-3 fatty acids affect mood and depression are complex and multifaceted, but include:

Influence on neurotransmitters: Omega-3 fatty acids can affect the level and function of neurotransmitters, such as serotonin, dopamine and norepinephrine, which play an important role in the regulation of mood. They can increase the release of these neurotransmitters and improve their transmission between nerve cells.
Reducing inflammation: Depression is often associated with an increased level of inflammation in the body. Omega-3 fatty acids have anti-inflammatory properties and can reduce the level of inflammatory markers, such as cytokines, which can help improve mood.
Improving the structure and function of cell membranes: DGC is the main structural component of cell membranes, including neurons membranes in the brain. Omega-3 fatty acids can improve the structure and function of cell membranes, which can help improve the transmission of nerve impulses and cognitive functions.
Neurogenesis: Omega-3 fatty acids can stimulate neurogenesis-the process of formation of new neurons in the brain. This process is important for training, memory and mood regulation.
Increase BDNF (neurotrophic factor of the brain): BDNF is a protein that plays an important role in the growth, survival and functioning of neurons. In people with depression, a decrease in the BDNF level is often observed. Omega-3 fatty acids can increase BDNF levels in the brain, which can help improve mood and cognitive functions.
The influence on the axis of the hypothalamus-thypophysis (GGN): The GAG axis is a neuroendocrine system that reacts to stress. In people with depression, dysfunction of the GAG axis is often observed. Omega-3 fatty acids can regulate the function of the GGN axis and reduce the level of cortisol-stress hormone.

III.B. Clinical research omega-3 and depression:

Numerous clinical studies studied the effect of omega-3 fatty acids on depression. The results of these studies are ambiguous, but many of them show that omega-3 fatty acids can be useful in the treatment of depression, especially in combination with other treatment methods such as antidepressants and psychotherapy.

Meta analysis: Some meta-analyzes (analyzes combining the results of several studies) showed that additives with omega-3 fatty acids can have a positive effect on the symptoms of depression, especially the mood, anxiety and impaired sleep.
The ratio of EPK and DGK: Studies show that the EPC can be more effective than the DGC in the treatment of depression. Some studies have shown that additives with a higher EPC content have a more pronounced antidepressant effect.
Type of depression: Omega-3 fatty acids can be more effective for certain types of depression, such as mild and moderate depression, as well as depression, resisting antidepressants.
Additional therapy: Omega-3 fatty acids are often used as additional therapy for antidepressants. Some studies have shown that the addition of omega-3 fatty acids to antidepressants can improve the effectiveness of treatment and reduce side effects.
Depression prevention: Some studies show that omega-3 fatty acids can be useful in the prevention of depression, especially in people with a high risk of developing this disease, such as pregnant women and people with a family history of depression.

III.C. Omega-3 with various mood disorders:

In addition to depression, omega-3 fatty acids can be useful for other mood disorders, such as:

Bipolar disorder: Some studies show that omega-3 fatty acids can help stabilize the mood in people with bipolar disorder and reduce the frequency and severity of episodes of depression and mania.
Seasonal affective disorder (SAR): Omega-3 fatty acids can help improve the mood in people with SAR, especially in the winter months, when there are fewer sunlight.
Postpartum depression: Some studies show that omega-3 fatty acids can help prevent and treat postpartum depression.
Alarm disorders: Omega-3 fatty acids can help reduce anxiety and improve the mood in people with anxious disorders, such as generalized alarming disorder and social alarming disorder.
Premenstrual dysphoric disorder (PMDR): Omega-3 fatty acids can help reduce PMDR symptoms, such as irritability, mood swings and depression.

IV. Dosage and methods of use of omega-3

The dosage of omega-3 fatty acids can vary depending on individual needs and health status. It is recommended to consult a doctor or nutritionist to determine the optimal dose for you.

IV.A. Recommended doses:

General recommendation: The general recommendation for the consumption of omega-3 fatty acids is 250-500 mg of EPK and DGK per day to maintain overall health.
Depression: For the treatment of depression, higher doses of omega-3 fatty acids may require, usually from 1000 to 4000 mg of EPK and DHG per day. It is important to note that the doses above 2000 mg per day should be taken only under the supervision of a doctor.
The ratio of EPK and DGK: Some studies show that for the treatment of depression it is preferable to use additives with a higher EPC content than DGK. The recommended ratio of EPC to DGK is 2: 1 or 3: 1.
Prevention: For the prevention of depression, 500-1000 mg of EPK and DGK per day can be enough.
Pregnancy and breastfeeding: Pregnant and lactating women are recommended to consume at least 200-300 mg of dvgk per day to maintain the development of the brain and vision of the child.

IV.B. Output forms and selection of additives:

Omega-3 fatty acids are available in various forms of release, including:

Fish oil: Fish oil is the most common form of omega-3 additives. It contains EPK and DGK and is available in the form of capsules, liquid forms and chewing tablets. It is important to choose fish oil from trusted manufacturers in order to avoid pollution with heavy metals and other toxins.
Crill oil: Krile oil is another source of omega-3 fatty acids, which contains EPK and DGC in the form of phospholipids, which can improve their absorption. Croil oil also contains antioxidant Astaxantin.
Algae oil: Algae oil is a plant source of EPK and DGK, which is suitable for vegetarians and vegans. It is produced from seaweed, which are the main source of omega-3 fatty acids for fish.
Vegetarian/vegan sources: In addition to algae oil, vegetarians and vegans can receive Alk from plant springs such as linseed seeds, chia, walnuts and soy oil. However, as mentioned earlier, the transformation of the ALK into EPC and the DGC in the body is ineffective, so it is recommended to consider the possibility of taking additives with algae oil.

When choosing additives with omega-3 fatty acids, the following factors should be taken into account:

Content of EPK and DGK: Pay attention to the content of EPK and DGC in one portion, and not just the total content of omega-3 fatty acids.
Quality and cleanliness: Choose additives from trusted manufacturers that guarantee the quality and cleanliness of their products. Pay attention to the availability of certificates of independent laboratories confirming the absence of pollution with heavy metals, PHB and other toxins.
Output form: Select the output form that is most convenient for you to use. Capsules can be more convenient for taking, but liquid forms can be more economical and allow you to easily adjust the dosage.
Taste: Some additives with fish oil can have a fish flavor or cause fish belching. If this is a problem, you can choose additives with an endo -absorbal coating, which prevents the dissolution of the capsule in the stomach and reduces the fish flavor.

IV.C. Tips for admission omega-3:

Take with food: Reception of omega-3 fatty acids with food containing fats can improve their absorption.
Divide the dose: If you take high doses of omega-3 fatty acids, divide them into several techniques during the day to reduce the risk of side effects.
