Also known as the energy vitamin, Vitamin B3, or Niacin, is essential for metabolism, circulation, and brain function.
It helps the body convert food into energy, maintain healthy skin, and keep the nervous system strong.
Because it supports over 400 biochemical reactions, Niacin is one of the most vital nutrients for total health.
🌸 What Is Vitamin B3 (Niacin)?
Vitamin B3 is a water-soluble B-complex vitamin that includes two active forms:
- Nicotinic acid
- Nicotinamide (niacinamide)
Both are involved in energy metabolism and DNA repair.
Niacin is also needed to produce NAD and NADP, coenzymes that power every cell in your body.
Your body can make small amounts of Niacin from the amino acid tryptophan, but dietary sources are still crucial.
🍽️ Foods Rich in Vitamin B3
Vitamin B3 is widely available in both animal and plant foods.
🥩 Animal-Based Sources
- Chicken and turkey (especially breast)
- Tuna, salmon, and sardines
- Beef and pork
- Liver and other organ meats
- Eggs and milk
🌿 Plant-Based Sources
- Peanuts and sunflower seeds
- Whole grains (brown rice, barley, oats)
- Legumes (beans, lentils, peas)
- Mushrooms
- Avocado and sweet potatoes
- Fortified cereals and bread
💡 Tip: Soaking or sprouting grains and legumes improves Niacin absorption from plant-based foods.

Niacin supports enzymes that help your body break down nutrients efficiently.
6. Protects Cells from Oxidative Stress
As part of NAD and NADP, it helps repair DNA and reduce inflammation.
⚖️ Vitamin B3 Deficiency and Balance
Deficiency:
Lack of Niacin causes pellagra, a disease characterized by the “three Ds”:
- Dermatitis (skin irritation)
- Diarrhea
- Dementia
Early symptoms include fatigue, poor concentration, and cracked skin.

Too much Niacin from supplements can cause flushing, nausea, or liver strain — always consult a doctor before high-dose use.

- Pregnant women: 18 mg/day
🌸 How to Maintain Healthy Vitamin B3 Levels
