Niacin is a nutritional supplement created to assist individuals who need to supplement the amount of vitamin B3 in their bodies for health reasons. It is based on a single ingredient, a vitamin highly researched and believed to extend its benefits to many of the essential organs of the human body. This formula contains a high amount of the active substance: approximately 40 mg per serving, meaning 200% from the daily recommended value in case of adults.
However, the recommendations differ depending on age and sex (pregnant women, for instance, are advised to take 30 mg of vitamin B3 per day).
As this is not a researched supplement and its use has not been approved by the FDA, it is always best to consult an informed healthcare professional before using it.
