Niacin (Vitamin B3), is a water-soluble vitamin and is part of the B Complex. It is required for the metabolism of carbohydrates and protein into energy. Niacin also supports cardiovascular health, promotes increased blood flow, and supports the health of the nervous system.

Is Vitamin B3 Glaucoma?
Author: Dr Jin Huang, Discipline of Biomedical Science, Sydney Medical School, The University of Sydney
Vitamin B3 could prevent glaucoma
Glaucoma is a neurodegenerative eye disease characterised by the loss of ganglion cells, causing blindness. The loss in vision tends to start from the peripheral part of the visual field, resulting in tunnel vision. In most neurodegenerative diseases, impaired mitochondrial function appears to be the cause rather than the consequence. Mitochondria are the powerhouses of cells. They produce most of the cells’ energy and play a central role in cell death (Davis and Williams, 2012). Therefore, an effective treatment for neurodegenerative diseases would be to correct mitochondrial abnormalities early.
Recently, Williams and colleagues (2017) tested the above possibility using glaucoma-prone mice (DBA/2J mice). They found that “mitochondrial abnormalities are an early driver of neuronal dysfunction, occurring before detectable degeneration”. The study also reported taking vitamin B3 orally and/or gene therapy were effective when used as a preventative measure or as an intervention for glaucoma by supporting mitochondrial health and metabolism. Clear neuroprotection was already achieved at low levels of vitamin B3 with no effect on intra-ocular pressure. Excitingly, at the highest oral dose tested, “93% of eyes did not develop glaucoma”.
How does vitamin B3 work?
Australian researchers comment on latest glaucoma findings
In the February 2017 issue of Science, Professor Ian Trounce of the Centre of Eye Research Australia (CERA), and glaucoma specialist (and managing director of CERA), Jonathan Crowston, published a perspective on these findings. While they were very excited about the potential of these findings for the human eye, they cautioned against rushing out to buy vitamin B3 until human studies have been properly carried out.
While the mice studies showed no toxic effects of taking high doses of nicotinamide, equivalent doses will need to be tested on humans to ensure there are no side effects. High doses of vitamin B3 (niacin) are known to cause skin rashes, and while the amide form of the vitamin doesn't appear toxic at currently recommended levels, the effect of higher doses will need further study.
Professor Trounce said that while high doses shouldn't be taken at this stage, there was nothing to stop people from continuing to take multivitamins containing nicotinamide, or from eating a diet rich in vitamin B3.
