Customer Reviews (4.4 / 5 · 5 reviews)

Violet G. ★★★★★

After a few weeks of taking one with breakfast, I feel noticeably steadier in energy through the afternoon. The pills are small enough to get down without water if I'm in a hurry, which wasn't the case with the last niacin I tried.

Edward N. ★★★★★

The 500 mg tablets are easy to swallow, and I appreciate that it's a reputable form of B3. After a few weeks, I feel like my energy levels have stabilized without any weird side effects.

Alexander ★★★★★

I've been taking this niacin for a few weeks now and noticed my digestion feels more regular, likely from the grain-based sources listed. The 500 mg tablets are small enough to swallow easily without any aftertaste.
