Vitamin B3

Vitamin B3 Niacin

Vitamin B3 (or Niacin) supplementation has benefits that may extend to energy production, cognition, and longevity. This is because niacin supplementation increases cellular nicotinamide adenine dinucleotide (NAD+) levels. NAD is essential to cellular energy production, immune system, stress response, and healthy aging. NAD is essential for healthy brain function, as well as healthy nerves. 

We included niacinamide (the preferred version of niacin) at 100% of Australian Recommended Dietary Intake in order to support mental energy production and for optimal cognitive function.

The results of the study are consistent with two previous studies examining…supplementation of a B multivitamin.”


Benefit 3: Improves cognition

Niacinamide can improve cognition



La Rue A, et al. ‘Nutritional status and cognitive functioning in a normally aging sample: a 6-y reassessment.’ in The American journal of clinical nutrition, Volume 65, Issue 1, January 1997 pp 20-29 [Link


“Several significant associations (P < 0.05) were observed between cognition and concurrent vitamin status, including better abstraction performance with higher biochemical status and dietary intake of thiamine, riboflavin, niacin, and folate (rs = 0.19-0.29) and better visuospatial performance...Higher past intake of vitamins E, A, B-6, and B-12 was related to better performance on visuospatial recall and/or abstraction tests (rs = 0.19-0.28). Use of self-selected vitamin supplements was associated with better performance on a difficult visuospatial test and an abstraction test.”

This research study identifies that the risk of Alzheimer’s disease and age-related cognitive decline is reduced by Niacin that acts as a neuroprotector. 100 mg Niacin/ kg of Niacin was orally administered for 30 days and preliminary studies found that the neuroprotection effect is through the reduction in neuronal loss.


Rawji, Khalil S., et al. ‘Niacin-mediated rejuvenation of macrophage/microglia enhances remyelination of the aging central nervous system.’ Acta neuropathologica. 2020. pp. 1-17 [Link]


The research paper identifies the improved remyelination effect through Niacin administration in the demyelinated Central Nervous System. The vitamin treatment on 9-12 months old demyelinated mice promoted myelin debris clearance in lesions while also helping in remyelination. Thus Niacin is found to be safe and can be used as a regenerative therapy for chronic demyelinating diseases like Multiple Sclerosis.

Niacin “plays a role in both neuroprotection and neuronal death, giving it the utmost importance in the proper functioning of the Central Nervous System, neuronal development, and function.”


Niacin administration is found to “decrease the incidences of cardiovascular events, premature ageing, age-associated neurological disorders such as Alzheimer disease, Huntington disease, Amyotrophic lateral sclerosis, Muscular atrophy, Parkinson disease, squamous cell carcinoma”. It is also used as a therapeutic agent in the treatment of neurodegenerative diseases.
