niacin for depression

Niacin, also known as Vitamin B3, is an essential water-soluble vitamin that plays a key role in energy metabolism, cardiovascular health, brain function, and skin repair. It helps convert food into usable energy by supporting enzymes in the metabolic process and is critical for maintaining healthy cholesterol levels. Niacin is also known for improving blood circulation, reducing inflammation, and supporting the nervous system. Deficiency in Vitamin B3 can lead to pellagra, fatigue, depression, and skin disorders.

Whether obtained through niacin-rich foods like poultry, fish, nuts, and whole grains, or through supplementation, maintaining adequate niacin intake is vital for cellular repair, healthy digestion, and balanced neurotransmitters. However, excessive niacin supplementation can cause side effects such as flushing, liver stress, and insulin resistance, making proper dosage essential.

For individuals focusing on heart health, cognitive support, and energy optimization, niacin remains one of the most important B vitamins for overall wellness.
