Vitamin B1 (Tiamin)

Detailed Description: Tiamin, also known as vitamin B1, is a water -soluble vitamin that plays a key role in carbohydrate metabolism. It converts carbohydrates into the energy necessary for the normal functioning of cells, especially neurons. Thiamine exists in the form of thiaminepyroophyfosphate (TPP), which is a coherent for several important enzymes involved in the metabolism of glucose and amino acids.
Benefits for Brain Health: Tiamine is important for normal cognitive function. He participates in the synthesis of neurotransmitters, such as acetylcholine, who plays a decisive role in memory and training. Tiamin helps maintain the health of the myelin shell, which surrounds and protects the nerve fibers, ensuring the effective transmission of nerve impulses. Studies show that the adequate level of thiamine can improve concentration and memory, especially in older people.
Deficiency Symptoms: Tiamine deficiency can lead to various neurological problems. Early signs include fatigue, irritability, a decrease in concentration and short -term memory loss. A severe deficiency of thiamine can lead to Beri-Berie’s disease, which affects the nervous system, heart and brain. Alcoholics are at risk of thiamine deficiency due to poor nutrition and violation of absorption. Vernik-Korsakov’s encephalopathy, a neurological disorder, characterized by confusion, problems with coordination and memory problems, is often associated with a tiamine deficiency in alcoholics.
Food Sources: Good sources of thiamine include whole grains (for example, brown rice, oatmeal), legumes (beans, lentils), meat (especially pork and liver), nuts and seeds. Enriched products, such as bread and cereals, are also good sources.
Supplementation (if applicable): Tiamine is available as an additive in various forms, including tablets, capsules and injections. It is often contained in multivitamin complexes. Tiamine additives can be useful for people with a deficiency of thiamine, such as alcoholics or people with malabsorption.
Dosage and Safety: The recommended daily dose of thiamine is about 1.2 mg for men and 1.1 mg for women. Tiamin is usually considered safe even in high doses, since it is water and excess is excreted in the urine. However, very high doses, rarely, can cause nausea, vomiting and dizziness.
Interactions: Tiamin can interact with some drugs such as diuretics that can increase the excretion of thiamine in urine.
Recent Research: Recent studies study the potential role of thiamine in the prevention and treatment of Alzheimer’s disease and other neurodegenerative diseases. Studies show that thiamine can help protect the brain from damage caused by oxidative stress and inflammation.

Vitamin B2 (Riboflavin)

Detailed Description: Riboflavin, or vitamin B2, is an important water -soluble vitamin necessary for cellular respiration, energy production and metabolism of fats, carbohydrates and proteins. It acts as a coherent in many redox reactions in the body.
Benefits for Brain Health: Riboflavin plays a role in protecting the brain from oxidative stress, since it is a component of antioxidant enzyme glutathionreductase. It is also important for energy production in brain cells. Some studies show that riboflavin can be useful for the treatment of migraine, since it can improve the function of mitochondria.
Deficiency Symptoms: Riboflavin deficiency can lead to symptoms such as ulcers in the corners of the mouth (Angular Heilit), inflammation of the tongue (glossitis), dermatitis and photosensitivity. Neurological symptoms may include fatigue, headaches and cognitive disorders.
