ELI5: Explain Like I'm 5

Niacin (substance)

Niacin is a type of vitamin that helps our bodies work properly. Imagine your body is like a car, and niacin is like the fuel that helps the car drive.

Niacin is important because it helps turn the food we eat into energy that our body can use. Just like how you need food to have energy to run and play, our bodies need niacin to have energy to move and do things.

But niacin does more than just help us have energy. It also helps keep our skin, eyes, and nervous system healthy. Imagine niacin is like the superhero of vitamins, protecting our bodies from harm!

We can get niacin from eating foods like meat, fish, and grains. But sometimes our bodies may not get enough niacin from the food we eat, so we can also take niacin as a vitamin supplement. It's important to ask a grown-up or a doctor before taking any kind of vitamin supplement, though!
