Nicotinamide, also known as niacinamide, is a form of vitamin B3 that plays a crucial role in various bodily functions. It is a water-soluble vitamin that is essential for the proper functioning of enzymes involved in energy metabolism and DNA repair. Nicotinamide is found in many foods, making it relatively easy to obtain through a balanced diet.
In recent years, nicotinamide has gained popularity as a dietary supplement and a key ingredient in skincare products. Its potential health benefits, including its role in skin health and anti-aging, have attracted significant attention from researchers and consumers alike. This article explores the foods high in nicotinamide, its health benefits, recommended intake, and potential side effects.

What is nicotinamide?
Nicotinamide, also known as niacinamide, is one of the two active forms of vitamin B3, the other being niacin (nicotinic acid). It is a water-soluble vitamin that is essential for the proper functioning of enzymes in the body. Nicotinamide is involved in various metabolic processes, including energy production, DNA repair, and the synthesis of fatty acids and cholesterol.
Unlike niacin, nicotinamide does not cause flushing, a common side effect associated with high doses of niacin. This makes nicotinamide a preferred choice for individuals seeking the benefits of vitamin B3 without the discomfort of flushing.
Health benefits of nicotinamide
Nicotinamide has been studied for its potential health benefits, particularly in relation to skin health and aging. Some of the key health benefits of nicotinamide include:
Skin health
Nicotinamide has been shown to improve skin barrier function, enhance hydration, and reduce the appearance of fine lines and wrinkles. It also has anti-inflammatory properties that can help soothe irritated skin and reduce redness.
Anti-aging
Research suggests that nicotinamide may help slow down the aging process by promoting DNA repair, reducing oxidative stress, and improving mitochondrial function. These effects may contribute to increased longevity and improved overall health in older adults.
Diabetes management
Some studies have suggested that nicotinamide may have a protective effect on pancreatic beta cells, which are responsible for insulin production. This has led to interest in its potential role in diabetes prevention and management.
Cardiovascular health
Nicotinamide has been shown to improve lipid profiles by reducing triglycerides and increasing high-density lipoprotein (HDL) cholesterol levels. This may help reduce the risk of cardiovascular diseases.
Neurological health
There is growing evidence that nicotinamide may have neuroprotective effects and could be beneficial in conditions such as Alzheimer’s disease and Parkinson’s disease. Its ability to promote mitochondrial function and reduce inflammation may contribute to its protective effects on the nervous system.
Recommended intake of nicotinamide
The recommended intake of nicotinamide varies depending on age, sex, and life stage. The National Institutes of Health (NIH) provides the following dietary reference intakes (DRIs) for niacin, which includes both niacin and nicotinamide:
– Infants (0-6 months): 2 mg NE/day
– Infants (7-12 months): 4 mg NE/day
– Children (1-3 years): 6 mg NE/day
– Children (4-8 years): 8 mg NE/day
– Children (9-13 years): 12 mg NE/day
– Males (14-18 years): 16 mg NE/day
– Females (14-18 years): 14 mg NE/day
– Males (19 years and older): 16 mg NE/day
– Females (19 years and older): 14 mg NE/day
– Pregnant women: 18 mg NE/day
– Lactating women: 17 mg NE/day
It is important to note that these recommendations are for total niacin intake, which includes both dietary sources and supplements. Most people can obtain sufficient niacin from a balanced diet that includes a variety of foods.
Potential side effects of nicotinamide
Nicotinamide is generally considered safe when taken at recommended doses. It is well-tolerated by most individuals and does not cause the flushing associated with high doses of niacin. However, some people may experience mild side effects, including:
– Gastrointestinal disturbances: Some individuals may experience nausea, diarrhea, or abdominal discomfort when taking nicotinamide supplements.
– Skin reactions: In rare cases, nicotinamide may cause skin irritation or allergic reactions, such as rashes or itching.
– Liver toxicity: Although rare, high doses of nicotinamide (greater than 3 grams per day) may cause liver toxicity. It is important to avoid exceeding the upper limit of 35 mg per day for adults unless under medical supervision.
– Interactions with medications: Nicotinamide may interact with certain medications, such as blood thinners and diabetes medications. It is important to consult a healthcare professional before starting nicotinamide supplements, especially if you are taking other medications or have underlying health conditions.
Overall, nicotinamide is a safe and well-tolerated form of vitamin B3 that can provide various health benefits. However, it is always advisable to consult a healthcare professional before starting any new supplements, especially if you have existing health conditions or are taking other medications.
Foods high in nicotinamide
Nicotinamide is found in a variety of foods, particularly those that are rich in protein. Some of the best dietary sources of nicotinamide include:
– Meat and poultry: Chicken, turkey, beef, and pork are all excellent sources of nicotinamide. Organ meats, such as liver, are particularly high in this vitamin.
– Fish: Fish, especially fatty fish like salmon, tuna, and mackerel, are good sources of nicotinamide.
