my mom was doing well on the time release Niacin { for high cholesterol} but started getting heartburn so doc said stop for 2 weeks and see if it goes away.
- and it did- so she started it again at a slightly lower dose- and heartburn returned in a few days.
She did have heartburn while taking a bone builder a few yrs ago.

She is going to the doctor today - but I just wondered if TR niacin can cause acid reflux/heartburn?
