1. Glycine.
This amino acid helps improve mental performance and concentration. Taking glycine is especially necessary during times of stress and if you cannot concentrate. During stress, it improves the functioning of neurons and activates cellular respiration. It is not necessary to take glycine supplements; there are foods that contain it. Quail eggs, pumpkin seeds, ginger, peanuts, walnuts and pine nuts, sesame, marmalade, pistachios, basil, soybeans are especially rich in glycine.
2. Beta-alanine.
The brain needs a lot of energy to function, and this amino acid is its source. Alanine also strengthens the immune system and regulates glucose levels. This amino acid helps to reduce irritability and apathy, and also increases concentration, especially in stressful situations. Because alanine regulates glucose levels, you may not feel hungry for long periods of time. Beta-alanine is found in the following food products: meat, eggs, gelatin, dairy products.
3. L-theanine.
It is an amino acid of natural origin that increases the body’s resistance to stress, energy and concentration. Studies have confirmed that L-theanine increases concentration and improves brain activity. It is useful to take it during intense brain activity.
The main action of L-theanine is to stimulate alpha activity in the brain. This amino acid affects the brain like meditation practices, allowing you to quickly calm down and at the same time not lose the ability to concentrate on complex tasks.
L-theanine lowers cholesterol and has a stimulating effect on the formation of nitric oxide. Thus, theanine prevents an increase in blood pressure and has a positive effect on the entire cardiovascular system. Theanine also helps the body produce glutathione, one of the most important antioxidants that protects against many diseases. Theanine is found in unfermented tea leaves.
4. Omega-3 fatty acids.
Essential fatty acids are important for the normal functioning of blood vessels. They reduce the risk of developing atherosclerosis, improve blood circulation and, accordingly, concentration. A person should consume about 5-10 g of omega-3 acids every day. Natural sources of such acids are wheat germ oil, flax seeds, mustard, soybeans, peanuts, sunflower seeds, walnuts, almonds, as well as fatty and semi-fatty fish.
5. Modafinil.
Modafinil is used as one of the most efficient drugs for treating daytime sleepiness, chronic fatigue, and loss of concentration. This substance was originally created to treat insomnia, somniphobia, sleepwalking, and other types of sleep disorder. Modafinil is found in such drugs as Modalert and Modavigil.
6. Zinc.
Zinc is important for the parts of the brain responsible for concentration and memory. With a significant deficiency of zinc, the functioning of the entire brain is disturbed. This can be manifested by hallucinations, impaired sense of smell and loss of taste.
