B vitamins

life science Maturity 11-13 Next article →

B vitamins are a special group of eight tools for our bodies. They are water-soluble, which means they can dissolve in water. These vitamins help our cells with metabolism. Metabolism is the way our bodies turn food into energy. They also help our bodies make red blood cells.

Because they are so helpful, many people take them as dietary supplements. When a supplement has all eight vitamins, it is called a vitamin B complex.

These vitamins work in a few different ways. Some act as coenzymes, which are helpers for chemical reactions. Others are precursors. A precursor is a starting part used to build something else.

Thiamin

For example, Vitamin B1, or thiamine, helps release energy from sugars. Vitamin B2, called riboflavin, helps with energy and activates other vitamins. Vitamin B3, or niacin, helps move energy during the breakdown of fat and alcohol.

Vitamin B5, or pantothenic acid, helps build important molecules like hormones.

Scientists and doctors study these vitamins to keep people healthy. They have learned that missing these vitamins can cause sickness. For instance, not enough thiamine can cause a disease called beriberi. This can hurt the nervous system and the heart.

A lack of niacin can lead to pellagra. This disease can cause skin problems and confusion.

Doctors also know that folate is vital for growing babies. It helps cells divide quickly during pregnancy. This helps prevent birth defects like spina bifida.

We can find many B vitamins in the foods we eat. Meat, fish, poultry, and eggs are very good sources. Dairy products like milk also have them.

Folic acid
Folic acid

You can find them in leafy green vegetables, beans, and peas. Some foods have extra vitamins added to them. This is called fortification. For example, many breakfast cereals and white flours are enriched with B vitamins. This helps make sure people get enough thiamine, riboflavin, niacin, and folic acid.

Some vitamins are harder to find in certain diets. Vitamin B12, or cobalamin, is mostly found in animal products.

It is not very common in plants. This means people who follow a vegan diet must be careful. They might need extra B12 to stay healthy. B12 is very important for making blood cells and protecting nerves. Even though we can get them from food, some people like athletes or elderly people use supplements to get more energy.
