無潮紅菸鹼酸，640 mg，100 粒膠囊

Took these every morning for two weeks now and my energy feels steadier through the afternoon, plus no weird heat or redness at all—the 640 mg dose is plenty without the flush. I was wary of the capsule size but they’re easy to swallow.

My skin used to get red and prickly with regular niacin, so switching to this no-flush version has been a total game changer for my daily routine. I take one capsule in the morning with breakfast and never have to plan around a weird hot flash at work. Two months in, my energy levels and cholesterol

The 640 mg dose is solid for daily support, and I love that I can take it on an empty stomach without any of that uncomfortable heat. My skin stays clear and I don't have to plan my day around a supplement.
