Niacin (Vitamin B3) functions

Niacin helps with the following functions:

  • Converting food into energy

  • Cellular metabolism

Niacin (Vitamin B3) dosage

The Nutrient Reference Value (NRV) is around 16mg per day. In every dose of Heights Smart Supplement, there is 30mg (equal to 3 chicken breasts or 12 medium baked potatoes) so 188% of the NRV.

Niacin research

Deficiency in niacin can result in pellagra, a systemic disease which is characterised by brain fog, psychiatric symptoms and even dementia. It is currently in trials to test improvement in cognitive function and synaptic plasticity, which could help to keep the brain healthy in people with Alzheimer’s Disease.

Niacin brain benefits

An antioxidant with an important role in cell signalling and DNA repair, niacin is key for a normally functioning nervous system.

Niacin (Vitamin B3) benefits

  • Essential for energy release 

  • Keeps skin healthy

  • DNA repair

  • Normal functioning of the nervous system

Plays well with

Vitamin B3 is available through diet, but mostly from animal sources, so those on a plant-based diet benefit from supplementation. To optimise the release of energy, it’s best consumed with other B vitamins.

Clever stuff

The brain requires niacin for the coenzymes NAD and NADP to get energy and function properly.
