Vitamin B6: why it's essential for energy, your nervous system, and hormonal balance

Mar/23/2026

Vitamin B6 is a key B vitamin that your body really needs.

Vitamin B6 is an important B vitamin that takes part in more than a hundred metabolic reactions in your body. Symptoms of vitamin B6 deficiency often include neurological and skin problems, including numbness/tingling in your hands and feet (peripheral neuropathy), confusion, depression, and a weakened immune system.

Vitamin B, briefly explained

When you're looking for reasons for fatigue, a low mood, or hormonal imbalance, you probably think of a lack of magnesium or iron. Much less often do you think of one of the key vitamins involved in all these processes: vitamin B6.

Vitamin B6 is an important B-complex vitamin that takes part in more than a hundred metabolic reactions in the body. It contributes to:

normal energy metabolism

the functioning of the nervous system

psychological function

the regulation of hormonal activity

reducing tiredness and fatigue

the normal functioning of the immune system ^[2]

Because of these properties, you’ll often find vitamin B6 in supplement formulas that support energy, mental performance, or hormonal balance. It’s in Junai HIM and Junai HER too, where one capsule provides 100% of the recommended daily intake of vitamin B6 to support key metabolic processes in your body ^[1] .

But what does vitamin B6 actually do in your body, how do you get it from food, and why does a modern diet sometimes not provide enough?

What is vitamin B6

Vitamin B6 is a collective name for a group of chemically related compounds:

pyridoxine
pyridoxal
pyridoxamine

These compounds are converted in the body into the active form pyridoxal-5-phosphate (PLP), which acts as a coenzyme in numerous metabolic processes.

A coenzyme means a vitamin that helps other enzymes carry out reactions in the body. Without it, many metabolic processes would not function normally.

Among the most important functions of vitamin B6 are:

amino acid metabolism
glycogen metabolism
neurotransmitter synthesis
red blood cell formation
homocysteine metabolism

Interestingly, about 70–80% of vitamin B6 in the body is stored in the muscles, where it participates in enzymes related to energy metabolism.

Why vitamin B6 is important for energy

One of the most common things people search for online is the question:

“What is vitamin B6 good for?” One of the most important answers is energy.

The European Food Safety Authority (EFSA) confirms that vitamin B6 contributes to normal energy-yielding metabolism [2].

This means it helps convert nutrients from food into energy that your body uses for:

movement

organ function

brain function

tissue repair

Vitamin B6 also plays a role in glycogen metabolism, which is the main energy reserve in your muscles [2].

That’s why vitamin B6 is especially important for:

active individuals

people with demanding lifestyles

anyone who often struggles with fatigue

EFSA also confirms that vitamin B6 contributes to the reduction of tiredness and fatigue [2].

Vitamin B6 and the nervous system

Your brain and nervous system are incredibly complex. To function normally, they need many vitamins and minerals.

And vitamin B6 plays a special role.

It contributes to the normal functioning of your nervous system and to normal psychological function [2].

Why?

Because it helps synthesize several key neurotransmitters, including:

serotonin

dopamine

GABA

noradrenaline

These neurotransmitters affect:

your mood

your focus

your motivation

your stress response

So it's no surprise that vitamin B6 is often mentioned in connection with:

mental energy

psychological balance

cognitive functions

The role of vitamin B6 in hormonal balance

A lesser-known fact about vitamin B6 is that it also helps regulate hormonal activity [2].

Hormonal balance is the result of a complex signaling system between your brain, glands, and tissues.

Vitamin B6 takes part in metabolic pathways that affect this system, so it can play an important supporting role in processes related to hormonal balance.

It's often included in supplement formulations designed to support:

your menstrual cycle

overall hormonal balance

your general well-being

Vitamin B6 and the immune system

Vitamin B6 also plays a role in how your immune system works.

EFSA confirms that vitamin B6 contributes to the normal function of the immune system [2].

Immune cells need many nutrients to function properly, and vitamin B6 is involved in amino acid metabolism and the formation of molecules that are important for the immune response.

In addition, vitamin B6 also contributes to the normal formation of red blood cells [2].

This matters because red blood cells carry oxygen throughout your body.

Vitamin B6 deficiency

You might run into a vitamin B6 deficiency in certain situations:

chronic illnesses

long-term alcohol use

some types of medication

a very restricted diet

If you're low on it, you might notice:

fatigue

irritability

depressed mood

skin changes

inflammation of the lining of your mouth

anemia

neurological problems ^[3]

In severe deficiencies, neurological symptoms are also described, such as seizures or other nervous system disturbances.

How much vitamin B6 you need

In the EU, the reference intake value for vitamin B6 is: 1.4 mg per day ^[4]

This value is also used on food supplement labels as 100% NRV.

According to EFSA, average requirements are slightly higher:

men: about 1.7 mg/day

women: about 1.6 mg/day [1]

During pregnancy and breastfeeding, your needs may be slightly higher.

which represents 100% of the recommended daily intake (RDI).

Because vitamin B6 is involved in numerous metabolic processes, it makes an important part of formulas that support your overall vitality.

Vitamin B6 is one of the key vitamins for the normal functioning of your body.

It takes part in energy metabolism, supports the nervous system, helps regulate hormonal activity, and contributes to reducing fatigue.
