Vitamin B6, also known as pyridoxine, is one of the most versatile and hardworking vitamins. It plays a role in over 100 enzyme reactions, helping your body convert food into energy, keep your brain sharp, and maintain a strong immune system.

Because it is water-soluble, your body doesn’t store much of it, which means you need to get enough every single day through food or supplements.

How Does Vitamin B6 Work in the Body?

To begin with, Vitamin B6 acts as a coenzyme in protein metabolism, helping break down and use amino acids efficiently.

Moreover, it supports neurotransmitter production, such as serotonin and dopamine, which regulate mood and sleep.

In addition, it aids in hemoglobin formation, keeping anemia at bay, and strengthens immune function by supporting antibody production.

Vitamin B6 is distributed throughout the body. Specifically:

• In the brain: It helps synthesize neurotransmitters, impacting mood, memory, and sleep.
• In the muscles: It converts stored glycogen into glucose for energy.
• In the blood: It supports hemoglobin production and helps prevent anemia.
• In the immune system: It promotes antibody production, boosting defense against infections.

Types of Vitamin B6

If your diet isn’t sufficient, supplements can provide additional support. The most common forms include:

• Pyridoxine Hydrochloride (HCl): Standard and widely available.
• Pyridoxal-5-Phosphate (P5P): Active form, helpful in special cases like genetic disorders.
• B-Complex Supplements: Combine B6 with other B vitamins for synergistic support.

But before starting supplements, it’s important to know the safest way to take them.

Look out for these common symptoms:

• Fatigue and irritability
