Choline is a nutrient directly related to brain function, and as it is a precursor of acetylcholine, a chemical substance that directly intervenes in the transmission of nerve impulses, it accelerates the production and release of neurotransmitters, which causes you have better memory and greater learning capacity.

Although choline is produced in small amounts in the body, it needs to be consumed in the diet to avoid lack of it. Thus, choline can be found in broccoli, flaxseed or almonds and its main food source is egg yolk. Choline can also be taken as a food supplement.

What is the hill for

Choline helps with several complex functions in the body, being the precursor to the synthesis of neurotransmitters such as acetylcholine. In addition, it is also necessary for the production of essential components of the cell membrane, such as phospholipids, phosphatidylcholine, and sphingomyelins, which are not only part of the structural part of the membrane, but also influence its functions.

In addition, choline is also needed to reduce concentrations of homocysteine, a substance that is linked to brain damage and other chronic diseases. Studies have shown that this compound (homocysteine) is elevated in degenerative diseases such as Alzheimer's, dementia, Parkinson's disease, epilepsy, cardiovascular disease and cancer. Thus, choline may play a role in preventing these diseases.

Choline is also involved in lipid synthesis, regulation of metabolic pathways and detoxification of the body, improving liver function.It can also participate in important functions during pregnancy, contributing to the baby's neuronal development and preventing neural tube defects.
