Niacin 250 mg

The 250 mg strength of niacin is a non-prescription dietary supplement and is available as a controlled-release tablet. The 250 mg supplements are the lowest strength available in this form of niacin. When using niacin supplements, it is best to start with a low dose and increase it slowly (known as titration). If you happen to start taking niacin at the full recommended dose for improving cholesterol, you probably won't stay on it very long, due to intolerable side effects, particularly the niacin flush. A sample titration schedule for controlled-release niacin supplements (SR niacin) include:
  • Week 1 -- 250 mg twice daily
  • Weeks 2 through 5 -- 500 mg twice daily
  • Weeks 6 through 9 -- 750 mg twice daily
  • Weeks 10 and beyond -- 1000 mg twice daily.


You may notice that the labels for non-prescription niacin products (especially SR niacin) recommend much lower, once-daily doses. This is because these products are nutritional supplements (not FDA-approved medications). Many healthcare providers do not recommend non-prescription niacin SR products, due to an apparently higher risk for liver damage.
