When it comes to good health, most people talk about Vitamin C or Vitamin D. But there’s another group of vitamins that deserves just as much attention — Vitamin B. Unlike a single vitamin, Vitamin B is actually a family of eight nutrients that work together to keep your body energized, protect your brain, and support your overall well-being.

Taking Vitamin B complex daily may help boost energy, improve mood, support healthy skin and hair, and protect against deficiency symptoms like fatigue and weakness. But what exactly does Vitamin B do, and how much do you really need? Let’s break it down.

What Is Vitamin B?

Vitamin B is a group of water-soluble vitamins, meaning the body does not store them for long. This is why you need to get them daily through food or supplements. Each B vitamin has a unique role, but together they form the Vitamin B complex.

These vitamins are vital for:

Turning food into energy.
Supporting the nervous system.
Producing red blood cells.
Maintaining healthy skin, hair, and nails.
