Is that a lot?

The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:

  • At 1 serving a day, the most its directions give, the label lists 500 mg of niacin, 14.3 times the adult Tolerable Upper Intake Level.

The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.

The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.

Directions
Suggested usage: Take 1 capsule daily as needed, preferably with a meal, or as directed by your healthcare practitioner.
Warnings
Caution/Interactions: The Tolerable Upper Intake Level for all forms of Niacin for adults is 35 mg/day based on flushing as the critical adverse effect; however, the form of niacin in this product is unlikely to cause a flushing response. High-dose Niacin has been associated with liver dysfunction. Although this occurs most commonly with slow-release Niacin, it can occur with any type of Niacin when taken at a daily dose of > 500 mg (usually greater than or equal to 3 g). Regular blood tests to evaluate liver function are recommended when using high-dose Niacin.
The anti-TB drug Isoniazid may increase the need for Niacin.
If you have liver disease, ulcers, gout, gallbladder disease, or drink alcohol, do not take high-dose Niacin unless directed by your healthcare practitioner.
High-dose Niacin may interact with statin drugs and may interfere with the absorption of tetracycline. If you are taking tetracycline, take at least two hours before or after taking Niacin.
Do not eat freshness packet. Keep in bottle.
