Customer Reviews (4.4 / 5 · 5 reviews)

Timothy ★★★★★

I take one of these each morning with breakfast and have noticed a real difference in my energy levels throughout the day. The 500 mg dosage is easy to swallow and doesn't leave any aftertaste.

Zoe Z. ★★★★★

My blood work numbers are looking better since I started taking these—the 500 mg dose is perfect for my daily routine. They're easy to swallow and don't leave any aftertaste.

Stella E. ★★★★★

I've been taking these for a couple months since niacin is hard to get enough of through food alone, and my levels finally came back in the normal range at my last checkup. The 500 mg dose means one tablet a day is all I need, which is nice.
