🔋 Turning Food Into Usable Energy
Vitamin B3 is a key player in cellular energy production.
It helps your body:
Convert carbohydrates, fats, and proteins into energy
Support normal metabolism
Reduce fatigue and weakness
Without enough niacin, energy levels can dip even when you’re eating enough.
🧠 Brain & Nervous System Support
Your brain is an energy-hungry organ—and Vitamin B3 helps fuel it.
Niacin supports:
Normal brain function
Memory and concentration
Healthy nerve signaling
Low levels may show up as brain fog, irritability, or poor focus.
✨ Skin, Digestion & Circulation
Vitamin B3 helps maintain tissues that renew quickly.
It supports:
Healthy skin
Normal digestion
Good blood circulation
This is why niacin deficiency often shows up on the skin first.
⚠️ What Happens If You’re Low? (Pellagra)
Severe Vitamin B3 deficiency causes pellagra, classically remembered by the 3 Ds:
Dermatitis – dark, scaly skin rashes
Diarrhea – digestive problems
Dementia – confusion, memory issues
(If untreated, a fourth D—death—can occur, which is why this vitamin matters.)

Meat and poultry

💡 Fun fact: Your body can also make small amounts of niacin from the amino acid tryptophan.
