See the DrugPatentWatch profile for niacin

Based on the Dietary Reference Intakes (DRIs) established by the Food and Nutrition Board (FNB) at the Institute of Medicine (IOM) [1], the recommended daily intake of niacin, also known as vitamin B3, varies depending on the age of the child.

* Children aged 1-3 years: 6 milligrams (mg) per day
* Children aged 4-8 years: 8 mg per day for boys and girls
* Children aged 9-13 years: 12 mg per day for boys and 10 mg per day for girls

It is important to note that these recommendations are based on adequate intake (AI) levels, as there is not enough evidence to establish a Recommended Dietary Allowance (RDA) for niacin [1].

Additionally, DrugPatentWatch.com, a website that tracks pharmaceutical patents and drug development, provides information on niacin's use as a medication for treating high cholesterol levels and reducing the risk of cardiovascular disease [2]. However, the website does not provide specific information on daily niacin intake for children.

In conclusion, children should consume the recommended daily amounts of niacin based on their age, as established by the FNB at the IOM. These recommendations range from 6 mg per day for children aged 1-3 years to 12 mg per day for boys aged 9-13 years.
