Vitamin B3 and the Central Nervous System

Vitamin B3 (niacin) plays a critical role in supporting the central nervous system. It contributes to healthy brain function by aiding in neurotransmitter synthesis and facilitating the metabolism of glucose, the brain’s primary energy source. Adequate levels are associated with improved cognitive performance and mood regulation, while deficiency may result in neurological symptoms such as memory impairment and confusion.¹ ²

Vitamin B3 for Energy Production

By contributing to the conversion of carbohydrates, fats, and proteins into usable energy, niacin plays an essential role in cellular metabolism. As a component of the coenzyme NAD (nicotinamide adenine dinucleotide), it supports mitochondrial function, helping cells generate energy efficiently. Inadequate intake may lead to fatigue, highlighting the importance of vitamin B3 in sustaining daily energy levels.³

Vitamin B3 and Heart Health

By supporting healthy lipid metabolism, niacin contributes to cardiovascular health. It has been shown to reduce levels of LDL (low-density lipoprotein) cholesterol and triglycerides, while increasing HDL (high-density lipoprotein) cholesterol. These effects, along with its role in promoting blood circulation, help support overall heart health and may assist in reducing the risk of cardiovascular disease.⁴

Vitamin B3 and Skin

Commonly used in skincare formulations, particularly as niacinamide, vitamin B3 offers a range of benefits for skin health and appearance. It supports improved skin texture, helps reduce the visibility of fine lines and wrinkles, and contributes to a more even skin tone by diminishing hyperpigmentation. Its anti-inflammatory properties also make it beneficial for calming irritated skin and managing acne. These combined effects help promote a clearer, more radiant complexion.⁵ ⁶ ⁷
