The reaction01
What is a niacin flush?
A temporary warmth, redness and itching of the face, arms and chest.
NIH says supplements with 30 mg or more of nicotinic acid can cause it, with headache, rash and dizziness (NIH ODS, Niacin (consumer)). Cleveland Clinic lists flushing as a side effect that usually needs no medical attention (Cleveland Clinic, Vitamin B3 (niacin) oral supplements).
The doses02
At what dose does niacin flush start?
Typically at 30 to 50 mg or more of nicotinic acid.
The adult upper limit from supplements is 35 mg a day. Doses of 1,000 to 3,000 mg are far beyond it and can cause serious effects (NIH ODS, Niacin (health professional)).
| Amount | What sources say |
|---|---|
| 7.5 mg NE | VapoCept, as listed |
| 14 to 16 mg NE | Adult daily need (RDA) |
| 30 to 50 mg or more | Flushing typical (nicotinic acid) |
| 35 mg | Upper limit from supplements |
The 7.5 mg line03
Will 7.5 mg NE in VapoCept cause flushing?
By the numbers it is unlikely, but we cannot promise it.
7.5 mg is 25% of 30 mg, and 21% of the 35 mg limit (our arithmetic). The form, nicotinic acid or niacinamide, is not named in the files we have, and niacin equivalents mix forms. Check your bottle. The niacin page has more.

FAQ05
VapoCept questions people ask
What does a niacin flush feel like?
It feels like warmth, redness and itching or tingling of the face, neck, arms and upper chest, sometimes with headache. It is temporary. Cleveland Clinic says flushing usually needs no medical attention, but report liver signs such as dark urine or yellow skin.
Is niacin flush harmful?
Flushing itself usually needs no medical attention, according to Cleveland Clinic. The concern is high doses over time, which can harm the liver. If you have belly pain, dark urine or yellow skin or eyes, contact a clinician promptly.
Does niacinamide cause flushing?
Our sources link flushing to nicotinic acid, not niacinamide, though the VapoCept panel does not name its form. NIH says niacinamide at 3,000 mg a day or more can damage the liver. Check your bottle or ask the seller.
