Niacin, also known as Vitamin B3, is usually taken in capsule form after meals. This vitamin can help clean out your arteries and remove any cholesterol deposits that may have formed. Niacin is also ideal for helping your body detox from alcohol drinking or taking in a poor diet, and it’s shown to support brain and heart health.
We’re reviewing the best niacin supplements of 2025 so you can incorporate this beneficial vitamin into your daily routine. Our list begins with the Nutricost Niacin capsules, our top choice due to their potent, high-quality dose of Vitamin B3.
The Best Niacin Supplements of 2025
Nutricost Niacin Supplement
Best Overall
Nutricost’s Niacin supplement offers a potent dose of 500mg of Vitamin B3 per capsule, with 240 capsules per bottle. This high potency makes it likely to cause the “Niacin Flush,” particularly when consumed on an empty stomach. For those seeking a non-flush option, the brand recommends their Niacinamide supplement. This flush is caused by the dilation of capillaries, leading to heightened blood circulation toward the skin’s outer layer.
While research indicates several advantages associated with the niacin flush, it can be uncomfortable for certain individuals. Consultation with your healthcare provider is advised to determine the suitability of this product for your needs. This niacin supplement is non-GMO and gluten-free, undergoing third-party testing to ensure quality and safety. Manufactured in a GMP-compliant, FDA-registered facility, the brand emphasizes transparency in its ingredients and formulations, aiming to provide clear choices to support health for all. Its pure and potent formula earned this supplement the top spot on our list.
