Reduced stress
I started taking this for stress-induced sleeplessness. I'm pleased to say it has helped alleviate my heart palpitations and shortness of breath, allowing me to sleep better at night. My overall sense of relief has improved significantly.

No sleep disruption
Previously, I was prescribed Niaspan for cholesterol but struggled with flushing at night, disturbing my sleep. Switching to this truly flush-free niacin has been fantastic; I've experienced no flushing impacts on my sleep and don’t need to take aspirin now. I will monitor its effects on my cholesterol but I'm optimistic.

Improved sleep routine
I was glad to find that this niacin doesn’t cause flushing. Initially, one tablet had me waking to use the bathroom around 3 am, but now that I take two, I can sleep through until 7 am without interruption.

Good sleep enhancement
I was using niacinamide but opted for this flash-free alternative. There’s no flushing, and I feel like I'm sleeping well.
