Dopamine is also a neurotransmitter, and its formation requires vitamin B3 and iron.

Dopamine is a component necessary for forming and retaining memories.

Foods rich in vitamin B3 include brewer's yeast, turkey, halibut, pumpkin seeds and peanuts.

Foods rich in iron include calf's liver, apricots (especially dried apricots), walnuts, pumpkin seeds and raisins.

Maintaining memory requires B complex vitamins (vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B12, biotin, vitamin B9, folic acid).

Lack of these B vitamins will lead to memory decline, inattention, poor learning ability and even memory loss.

B vitamins are important for producing cells, especially brain cells.

Foods rich in B vitamins include brewer's yeast, chicken, kale, oatmeal, soybeans, fish, avocados and potatoes.

Emotional Chemicals Serotonin - The Pleasure Chemical Serotonin is produced only in the brain and is the most important chemical that makes people feel good.

Foods rich in the amino acid tryptophan help the brain produce serotonin.

Serotonin helps lift our mood and combat depression and lack of energy, helping us relax.

At night, when people fall asleep, the brain converts serotonin into melatonin, which helps maintain the normal operation of the body's biological clock and improves sleep quality.

Foods rich in serotonin include bananas, turkey, cottage cheese, sunflower seeds, brown rice, peanuts and legumes.

Dopamine - the pleasure-seeking chemical Dopamine is a neurotransmitter that encourages us to pursue pleasurable things, such as food, sex, and enjoying the feeling of love. It keeps our brains awake and helps us focus,

and improve short-term memory and thinking abilities.

It is very necessary for the brain to produce dopamine.

Like serotonin, dopamine is converted from amino acids in the brain, and foods rich in tyrosine assist the brain in producing dopamine.
