The role of serotonin and tryptophan in depression
Serotonin is a hormone, one of the neurotransmitters that transmits happiness from one neuron to another. However, it is synthesized from the essential amino acid tryptophan. It is rich in this amino acid, called the hormone of happiness, which is the amino acid of happiness. It depends on the source of stress.

Folic acid for depression

Folic acid has a beneficial effect on the nervous system, relieves fatigue, reduces stress. Its deficiency plays an important role in increasing anxiety, hyperactivity, aggression, mood swings, which can undoubtedly contribute to the development of depression. Recent studies show that nearly 40% of people affected by depression also have a deficiency of foxy acid.
Omega-3 fatty acids and fighting depression
One of the most important fatty acids for our brains is DHA. Docahexaenoic acid (DHA) is a polyunsaturated omega 3 fatty acid, belonging to the group of exogenous fatty Acids. A valuable source of both DHA and other omega 3 derivatives (EPA) are fatty seafood (tunnel, mackerel, Norway lobster). Instead, omega 6 is found mainly in plant-based products (nuts, olive oil, avocado).
What else is there for depression?
Our state of mind, our well-being, our mood are controlled by many factors. One of them (very important) is the diet. In addition to providing our body with valuable nutrients from which the brain draws energy for proper functioning, it's also important how we feed our meals, their taste, their smell, and even the color of the products we eat. It all stimulates our senses, gives us a sense of comfort, and improves our mood. The omega-3s in fish help fight depression. Besides being shown to have a significant effect on serotonin, folic acid, or omega-3 on our body's own products, the taste, smell, or even the colour of the foods we consume.
