I definitely flush, but I figure that’s because I need it due to high lp(a) and fibrin. The more I take it the less I flush, and an aspirin before hand stops it. I actually came to like the flush but had to stop because it started hurting my early really badly. That I have not found a way to stop. I probably would need to drop down to a lower dose.

Yes, I flush like a strawberry, even when just eating some breads high in niacin. But because of my cholesterol levels, I try to get niacin naturally when I can to supplement the other supplements I take to try and keep my cholesterol in check. After 30 years, I figured out I could no longer tolerate statins, so I look to other supplements to help along with diet and exercise.

Hi @db4him see answer from Dr. Carmen below.

I asked Dr. Carmen for her input to help people that get “the flush”, here is her response, hope that it helps. <div>

“A great question and so glad the guide is already sparking discussion on the forum!

The niacin flush is one of the most common concerns I hear around B3 supplementation, so this is really worth addressing properly.

The flush itself — the redness, warmth, and tingling that typically affects the face, neck, and chest — is a prostaglandin-mediated response triggered by nicotinic acid binding to receptors in the skin. It is completely harmless physiologically, but it can be quite alarming if you are not expecting it, and uncomfortable enough that many people abandon niacin altogether before experiencing its benefits.

My advice for people who flush:

The simplest solution is to switch forms. Niacinamide (nicotinamide) is the non-flushing form of B3 that works beautifully for general health, energy metabolism, DNA repair, and skin support — and the vast majority of people tolerate it without any reaction at all. For most people using B3 for general wellness rather than specific cholesterol management, niacinamide is the form I would recommend first.

For those who specifically want nicotinic acid for cardiovascular and cholesterol support — where the flush form genuinely has the stronger evidence base — here are a few practical strategies to reduce the reaction:

Start very low and increase slowly — beginning at 50–100mg and titrating up gradually over several weeks allows the body to adapt and the flush response typically diminishes significantly over time

Take with food — never on an empty stomach

Avoid hot drinks, alcohol, and hot showers around the time of dosing — all of these amplify the reaction

Take at bedtime — sleeping through the flush is a practical workaround many patients find helpful

Choose a slow or extended release formula — though it is worth noting that some extended release niacin formulations carry a higher risk of liver stress at therapeutic doses, so this is worth monitoring if going that route

It is also worth reassuring people that the flush tends to be worst in the first few weeks and genuinely does diminish with consistent use as the body adapts. Many patients report it fades to almost nothing within a month.

And for anyone interested in the longevity and NAD+ angle rather than cholesterol specifically — NMN or NR (nicotinamide riboside) are niacin precursors that support NAD+ production without causing any flush at all, and are worth exploring as an alternative avenue.”
