Omega‑3 a deprese – co říkají výzkumy a jak to využít

When working with omega‑3, esenciální mastné kyseliny, které tělo nedokáže samo vyrobit a musí je získat stravou. Also known as rybí olej, it is a key component of brain cell membranes. omega‑3 levels are often low in people suffering from deprese, duševní porucha charakterizovaná dlouhodobým smutkem a únavou. The connection is explained by esenciální mastné kyseliny, EPA a DHA, které podporují neurotransmiterovou rovnováhu. Research shows that adequate intake can reduce symptom severity, especially when combined with standard treatment.

Proč omega‑3 působí na náladu

Omega‑3 encompasses EPA (eikozapentaenová kyselina) and DHA (dokosahexaenová kyselina). EPA modulates inflammation in the brain, a factor linked to depressive episodes. DHA strengthens synaptic plasticity, helping neurons communicate efficiently. In practice, this means that a diet rich in fatty fish, chia seeds or algae oil can improve the biochemical environment that mood regulation depends on. Studies from 2020‑2023 consistently report that people who supplement with 1‑2 g EPA + DHA daily experience measurable mood lifts after 6‑12 weeks.

Another important attribute is that omega‑3 requires proper absorption. Vitamin D, magnesium and a balanced omega‑6/omega‑3 ratio (ideally 4:1 or lower) enhance its effectiveness. Without these cofactors, the fatty acids may not cross the blood‑brain barrier efficiently, limiting their impact on depressive symptoms. Therefore, a holistic approach that includes dietary adjustments, occasional supplementation, and regular check‑ups with a physician yields the best results.

Combining omega‑3 with antidepresiva, léky jako SSRI, které zvyšují serotonin v mozku has proven synergistic. Clinical trials show that patients who add omega‑3 to their prescription report faster remission and fewer side‑effects such as sexual dysfunction. The underlying mechanism is thought to be the stabilization of neuronal membranes, which allows antidepressants to work more uniformly.

Psychoterapie also interacts positively with omega‑3. When a person attends CBT or IPT sessions, the enhanced neuroplasticity provided by DHA can improve learning of new coping strategies. In other words, the brain becomes more receptive to therapeutic interventions. This synergy is why many clinicians recommend patients maintain a steady intake of omega‑3 during the whole course of psychotherapy.

Practical tip: start with a modest dose of 500 mg EPA + DHA daily for two weeks, then increase to 1 g if no adverse effects appear. Monitor mood changes using a simple journal – note sleep quality, energy levels and emotional reactivity. If after eight weeks there’s no improvement, consider consulting your doctor about adjusting the dose or adding a different supplement like S‑acetyl‑L‑carnitine, which also supports mitochondrial function.
