## Description

ENDUR-ACIN 250mg Niacin - Extended Release for Optimal Absorption & Low-Flush Vitamin B-3, 100 Tablets - Non-GMO, Vegan, Gluten Free - Endurance Products Company

Review: Hooray! With these, I can finally tolerate Niacin! - Hooray! With these, I can finally tolerate Niacin! Low-dose, so I could start small and build, as needed and tolerated. I've always flushed with Niacin. Even the other so-called "slow" types of Niacin made me flush. I had given up on Niacin, until a dear friend told me about these and explained why they were different from the rest. With these, I could start with just one 250 mg, and am now up to 750 mg per day (mild flushing only one day, but that was my fault...) Here's what I did: I started with one at night, had no problems, and just 2 days later, I tried increasing to two at night and experienced mild flushing the next day, so I dropped back to just one at night. After two weeks, I added the second one at night. No Flushing! Two weeks later, I added one in the morning, and have still had no more flushing! I am thrilled! Thank you Enduracin!

Good product

### ⭐⭐⭐⭐ no flushing. got a headache though.
*by S***N on February 17, 2020*

I'm having to work my way up to taking these. I took these for 2 days in a row and never experienced flushing, but I got a headache about 45 minutes after taking them that felt like someone hit me with a hammer. Since then I broke them in half. Keep in mind they aren't scored so they weren't made to break in half. But doing that has helped with the headache. I'm going to keep breaking them in half for a while then try to take them whole again. I just wanted to throw that out there to warn everyone you might get a headache.
