## Overview

Nutricost Niacin Powder offers 250 grams of pure Vitamin B3 in a clean, gluten-free, and non-GMO formula. Manufactured in FDA-registered, GMP-compliant facilities and third-party tested, it delivers a potent niacin flush known to support lipid profiles and cardiovascular wellness. Ideal for professionals seeking a customizable, cost-effective supplement to boost energy and heart health.

## Description

Nutricost Niacin powder uses only high quality Niacin (commonly known as Vitamin B3). Nutricost strives to provide the best supplements at the best prices. Please be aware that taking high dosages of Vitamin B3 (Niacin), especially when your body is not used to it, can lead to what is often referred to as the Niacin flush. A "niacin flush" is a temporary side effect of taking niacin; it's also a protocol used by some physicians to lower lipid profiles and boost heart health. Studies have shown that niacin flush has a lot of benefits. However, if you are looking for just the benefits of vitamin b3 without the flush, we'd recommend using a different form of Vitamin b3 such as Niacinamide.

Review: I use this every day - This goes into my lemon water every morning. I only use about 1/8 of a teaspoon, as my skin is a bit sensitive, and flushes more easily than most. I will tell you, 1/8 tsp is PLENTY. I'm not sure where they got the "1 scoop = 1 serving, but that is way overkill. My dosage has done wonders for my cholesterol levels, and I'm sure my heart is thankful for it. It's great to add into your gym drink, or just your workday water bottle. Niacin does provide healthy energy production benefits, as an added bonus. If you're skin flushes and burns with niacin, I recommend taking it before bed. The flushing will be gone when you wake up, and you'll never even know it warmed you up while you slept! This is a ridiculous bargain compared to buying capsules. If you're only taking the normal recommended dosage for adults per day (100%), this one jar will literally last years.
Review: Great supplement - Bought this to use on my ducklings and it works great but only used half the scoop

### ⭐⭐⭐⭐⭐ Great supplement
*by T***R on June 11, 2026*

Bought this to use on my ducklings and it works great but only used half the scoop

### ⭐⭐⭐⭐⭐ Do not take a full scoop the first time!!!
*by J***O on February 25, 2018*

This is a very potent supplement. I took one scoop the first time (recommended dosage) and the flush was horrendous. Most B complex supplements contain about 20 mg of Niacin. Nutricost recommends 1g per serving, which is about 50 times more than what is in a regular B complex pill. This is why I was literally burning when I took it, and could feel my heart pounding in my ears. I turned red like a lobster and the itching in arms and legs was intolerable. This lasted for about 2 hours. I took a cold shower hopping it goes away, and it did not. I was at a point I almost called 911. The only thing that worked was flushing it out by drinking about 64 oz of water. I am giving it 5 stars because the product is high quality. However, it believe Nutracost should include a note in the label suggesting to start with perhaps 1/4 of a scoop and work you way up until a comfortable tolerance level is reached.
