this natural source is responsible for our existence.

Did you know that without vitamin B9 our existence would be impossible? This water-soluble vitamin is responsible for many biochemical processes in the body, including the production of DNA. In fact, a deficiency in this nutrient can lead to birth defects and other health problems. Fortunately, our bodies can provide this from certain foods. Let’s take a closer look at the important properties of this vitamin.

Vitamin B9 or folic acid: what is it?

Vitamin B9, also known as folic acid, is a water-soluble vitamin. It is found in green leafy vegetables, legumes, nuts and fortified foods. It plays an important role in the development of the neural tube. Because it can help prevent birth defects in the brain and spine.

Folic acid is known for its involvement in the prevention of anemia and is essential for the production of red blood cells. Vitamin B9 is important for cell growth and DNA synthesis and is therefore essential for tissue repair and cell division. Although our bodies only need small amounts of folic acid, it’s important to make sure we’re getting enough from food or supplements.

Vitamin B9 deficiency can cause difficulty concentrating, shortness of breath and fatigue. In severe cases, it can cause neurological problems and even death. Fortunately, folic acid deficiency is relatively rare in developed countries. However, pregnant women and those who want to become pregnant are advised to take a food supplement every day to help prevent birth defects.

What are the properties of vitamin B9?

It is also called folate, pteroylmonoglutamic acid, pteroyl-L-glutamic acid, or pteroyl-L-glutamate. In the metabolic sequence of cell formation and division, this vitamin is the precursor of tetrahydrofolate (FH4 or THF4). The latter is a coenzyme that contributes to the formation of serine, methionine, pyrimidines, nucleic bases, and especially deoxyribonucleic and ribonucleic acids.

It is true that the body cannot produce vitamin B9. Even if it turns out that certain intestinal bacteria are still able to synthesize it, but in a rather limited amount. Vitamin B9 is absorbed in the small intestine and stored in the liver.

Recently, researchers have discovered that vitamin B9 may also play a role in preventing Alzheimer’s disease, heart disease, and certain types of cancer.
