Recommended Daily Intakes of Niacin
Niacin, or vitamin B-3, is an essential nutrient that is essential for a wide variety of life processes. It is found in many foods, including fortified cereals, breads, and pastas, as well as some meats and fish, nuts, eggs, and certain vegetables. Niacin has several important medical uses and recommended daily intakes of this fat-soluble vitamin vary depending on age, gender, health status, and other factors. For adults, the dietary reference intake is 14-16 milligrams (mg) per day for women and 16-18 mg per day for men. For pregnant and lactating women, the recommended intake is 18 mg per day. While the body can store niacin, getting an adequate amount of it is still important to maintain health, as niacin is involved in numerous bodily functions ranging from energy production to nerve signaling. A deficiency can cause inflammation, exhaustion, and other problems, so make sure to get your daily intake from both fortified foods and a balanced diet.
Side Effects of High Doses of Niacin
High doses of niacin, a fat-soluble vitamin, can have serious side effects. Although niacin can be found in a variety of food sources, some people take it in supplement form to help lower cholesterol. At high doses, niacin can cause skin flushing, itching and heat sensations. Additionally, it can cause dizziness, headache, nausea, diarrhea, and other gastrointestinal problems. High dose niacin can also cause liver toxicity and may be linked to an increased risk of stroke, although more research is needed to confirm this. Taking high doses of niacin should always be done under the supervision of a qualified healthcare provider to ensure safety.
Niacin or vitamin B3 is an essential fat-soluble vitamin with a wide range of health benefits. Research suggests that niacin can help with heart health, the metabolism of fats and carbohydrates, and that it might even have anti-aging properties. It is also an important component in energy production. Niacin is found in many foods, including poultry, meat, cereals, grains, and leafy green vegetables.
