What is Vitamin B3?
Niacin (also called vitamin B3) helps convert the food you eat into the energy you need. Niacin is important for the growth and function of cells in your body.
Niacin is found naturally in many foods and is fortified in some foods. The recommended amounts of niacin can be obtained by eating a variety of foods:
-
Animal foods such as poultry, beef, pork and fish
-
Some types of nuts, legumes and grains
-
Enriched and fortified foods, such as bread and cereals
All tissues in the body convert absorbed niacin into its main metabolically active form, the coenzyme nicotinamide adenine dinucleotide (NAD). More than 400 enzymes require NAD to catalyse reactions in the body, which is more than for any other vitamin-derived coenzyme.
About NAD+
Nicotinamide adenine dinucleotide (NAD+) is a form of vitamin B3 that occurs naturally in the body and is associated with energy production and ensuring proper cellular function.
It is one of the most vital nutrients we need to function, as its primary role is to transport energy from one cell to another. This is how our body converts food and nutrients into energy that can be used by our cells.
NAD+ is also used to maintain a healthy metabolism and circadian rhythm. Supplementing our body's NAD+ levels can help boost our energy and vitality.
Nicotinamide adenine dinucleotide (NAD+) levels decline as we age because production slows.
Low NAD+ levels are linked to numerous ageing-associated diseases including cognitive decline, cancer, metabolic disease, and frailty.
Therefore, restoring NAD+ levels with the NAD+ precursors nicotinamide riboside (NR) has emerged as potential approach to ameliorate ageing-related disease.
