What is in Rezistaf?

Each row as the label prints it, per serving of 10 tablets. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

This amount is far outside what other labels list for niacin, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD.

* % Daily Value computed from the printed amount and the FDA Daily Value (21 CFR 101.9); the label prints none for that row.
