Niacinamide vs Niacin: Niacin Flush Dose Requirements and What Causes It

A lot of people wonder what the difference is between niacinamide vs niacin. The main difference is that niacimide doesn’t tend to cause what’s known as the “niacin flush” as much.

What is the niacin flush?

A niacin flush is basically when someone takes niacin and they get a “flush” sensation in their chest and face. The niacin flushes basically is the face and chest to become flush and sometimes tingle or itch for few minutes. This is caused by flushing toxins from your system.

Why does Niacin do this? Niacin basically acts as a vasodilator. Vasodilation is when your capillaries, which are like smaller blood vessels, expand, or dilate, thus allowing more blood to flow through them. This vasodilation has a lot of health and athletic benefits. With vasodilation you increase the oxygen flow to the blood, increase red blood cell counts, and improve athletic performance both in the gym and on the field.vasodilationNow, the niacin flush is something that freaks people out when they first experience it. The niacin flush dose is when you take enough niacin and you experience a tingling in your face and chest. Some people not only experience a tingling but they also experience of itchiness. This usually happens within 4 to 6 minutes of taking a niacin supplement. When you take a niacin supplement it causes your capillaries to expand, allowing more blood to flow through them. In addition to allowing more blood to flow through your capillaries you’re allowing more toxins to be released from your fat deposits. These toxins being released is what can cause that tingling or itchy feeling on your face.

You don’t have to worry, though, because this will pass after few minutes. Also, it’s generally the worst the first time you experience it. After the first time its effects are less and less.

So, basically the niacin flushes are caused by a vasodilation and your capillaries expanding letting more blood into your system, but also more toxins being released.

Niacinamide vs Niacin

Because people are scared of the niacin flush, they often turn to niacinamide, which is known to combine with other elements in your body and does not cause the niacin flush.

You can see the molecular difference here. As you can see, they are very similar:


But, the niacin flush entering into your bloodstream and causing those capillaries to dilate is an essential part to reaping the benefits of taking niacin in the first place. If you are taking niacin, you want those capillaries to dilate! The only reason you would take niacinamide and not niacin is if you are looking for some of the other effects of niacin without that niacin flush. We have an article about uses for niacinamide for treating psychological issues: Niacinamide for Anxiety – Helps Depression, Social Anxiety, and Panic Attacks?

An example of this would be taking niacin to reduce your cholesterol. Now, most people are not interested in reducing your cholesterol, they’re actually taking a side to him increase their athletic performance. For this reason, you do not want to take niacinamide to increase your athletic performance instead of niacin.

Yes, niacin will give you that niacin flush, but that basically means that it’s working! Niacin causing the niacin flush will give you the effect that you want because you will are expanding the capillaries (vasodilation) and our increasing your red blood cell count and are going to deliver more oxygen to your muscles and brain. This allows you to have better performance for your workouts or sport.

For this reason, if you are looking to lower your cholesterol, then by all means go for niacinamide. But, if you’re looking to improve your athletic performance or physique than you want to niacinamide, grow a pair, and just deal with the niacin flush which only lasts a few minutes anyway.

Recommendations for Niacin

If you’re ready to read the benefits of niacin, then I recommend you try Niacin Max. Niacin Max has a unique method of delivery that beats out all other niacin supplements. Basically it’s a strip that you put under your tongue.

Now, well this might not seem like a big deal it really is. By having it as a strip that you put under your tongue instead of a pill that you swallow you are going to reap major benefits. The strip under your tongue allows it to bypass your digestive system making it work instantly. But instantly I mean in like 5 to 10 minutes. Seriously.

You see you like Niacin 500 milligrams in a bottle pills, or whatever. Guess what? You’re not going to get 500 milligrams into your bloodstream. Your stomach acid is going to eat up most of that anyway and you’re just going to get a fraction of it into your bloodstream where it will benefit you.


The science basically says that you get like 10 to 15% of the dose of niacin when you take the pill. On the other hand, you get more like 90% of the niacin when you take it under the tongue with something like Niacin Max. If this sounds interesting to you I suggest you check out their website here.

You can watch this guy experience the “niacin flush”. He makes a good point about not taking the “non-flushing” variety of niacin (which is the niacinamide) but he’s taking the 100mg pill. So, he’s actually getting the flush but without getting nearly as much of the benefits as he could by taking an under-the-tongue application like Niacin Max.
