Niacin, also known as vitamin B3, is an essential nutrient that plays a crucial role in the body's metabolism. It is important for converting food into energy and is also involved in DNA repair and cell signaling. Niacin is found in a variety of foods, including meat, fish, nuts, and whole grains.
Niacin deficiency can lead to a condition known as pellagra, which is characterized by symptoms such as diarrhea, dermatitis, and dementia. Severe niacin deficiency can be life-threatening if left untreated.
In addition to its role as a nutrient, niacin is also used as a supplement to help lower cholesterol levels and reduce the risk of cardiovascular disease. It works by increasing levels of HDL (good) cholesterol and lowering levels of LDL (bad) cholesterol and triglycerides. Niacin supplements are available over-the-counter and are often prescribed by doctors to help manage high cholesterol.
However, it is important to note that high doses of niacin can cause side effects such as flushing, itching, and liver damage. It is recommended to consult with a healthcare provider before starting niacin supplementation to determine the appropriate dosage and monitor for any potential side effects.
Overall, niacin is an important nutrient that plays a vital role in the body's overall health and metabolism. It is essential for maintaining proper energy levels and supporting cardiovascular health, but it is important to use caution when supplementing with niacin to avoid potential side effects.

- Nicotinic acid (niacin): The primary form used in supplements and medications.
- Nicotinamide (niacinamide): A milder form with fewer side effects, primarily found in food sources.
Functions:
Niacin plays crucial roles in various bodily functions, including:
- Energy metabolism
- DNA synthesis and repair
- Hormone production
- Nervous system function
- Skin and mucous membrane health
Sources:
- Food: Rich sources include poultry, fish, legumes, nuts, and whole grains.
- Supplements: Available in tablet, capsule, and powder forms.
Recommended Intake:
The recommended daily intake of niacin varies depending on age, sex, and health status. For adults, the recommended intake is 16-18 mg for men and 14-18 mg for women.
Benefits:
- Lowers cholesterol: Niacin has been shown to increase HDL ("good") cholesterol levels and decrease LDL ("bad") cholesterol levels.
- Improves blood sugar control: Niacin may help improve insulin sensitivity and reduce blood sugar levels.
- Protects against cardiovascular disease: By reducing cholesterol and improving blood sugar control, niacin may help protect against heart disease and stroke.
- Boosts energy: Niacin is involved in energy metabolism and may help reduce fatigue.
- Supports skin health: Niacinamide is known to improve skin barrier function and reduce inflammation, making it beneficial for treating acne and other skin conditions.
Side Effects:
- Flushing (niacin): A temporary, harmless side effect that typically occurs when high doses of niacin are consumed.
- Gastrointestinal distress: Niacin may cause nausea, vomiting, or diarrhea.
- Liver damage (niacin): High doses of niacin can increase the risk of liver damage, especially in those with underlying liver issues.
Precautions:
- Pregnant or breastfeeding women should consult with a healthcare professional before taking niacin supplements.
- Individuals with a history of liver or kidney disease should avoid high doses of niacin.
- Niacin may interact with certain medications, such as statins and blood thinners.
Conclusion:
Niacin is an essential vitamin that plays a vital role in maintaining overall health and well-being. While it can be obtained from dietary sources, supplements may be necessary to meet recommended intake levels or address specific health conditions. However, it's important to consult with a healthcare professional before taking niacin supplements to assess individual needs and potential risks.
