There is a 20 mg per day recommended Daily Value (DV) of niacin from any source and in any form. The Tolerable Upper Intake Level (UL) for niacin is set at 35 mg per day, which is primarily based on one form of vitamin B3 (niacin itself, also called nicotinic acid) potentially causing an uncomfortable "niacin flush". However, all forms of niacin are lumped together under this arbitrary upper limit, with no real scientific justification given for their inclusion. Federal regulations also require that all forms of niacin be lumped together and primarily labeled as "Niacin", with the exact form(s) secondarily listed in parentheses. This understandably leads to a lot of confusion about the use and potential side effects of various forms of niacin.

It is well documented that niacinamide (nicotinamide) does not cause a niacin flush. Nor does inositol hexanicotinate, sold commonly as "Flush Free Niacin" and utilized by many physicians as part of their cholesterol management programs. This means that these forms should probably not be (but are) included in the UL for niacin (nicotinic acid).
