Nicotinamide Riboside and Celiprolol

Here is the interaction we found between these two, with the evidence behind it.

Minor

ANTIHYPERTENSIVE DRUGS

Why this applies to Celiprolol

Celiprolol falls under ANTIHYPERTENSIVE DRUGS — the group Nicotinamide Riboside interacts with.

Theoretically, nicotinamide riboside may have additive effects with antihypertensive drugs, potentially increasing the risk for hypotension.
One small clinical study suggests that nicotinamide riboside can modestly reduce blood pressure in hypertensive patients. However, other clinical research did not find a reduction in blood pressure when compared with control.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Celiprolol is a beta-blocker you take to lower blood pressure (and to ease the workload on your heart). The thought here is that nicotinamide riboside might nudge your blood pressure down a little too, so stacking the two could, in theory, lower it a bit more than expected.

I want to be honest about how shaky this is. It's rated minor and is purely theoretical, based on one small study where NR modestly dropped blood pressure, while other studies showed no change at all. If anything happened, you might notice mild lightheadedness, dizziness when standing, or feeling more tired than usual. Nothing dramatic. Still, it's worth a quick chat with your pharmacist or doctor, and checking your blood pressure at home is an easy way to stay ahead of it.

About Nicotinamide Riboside

What is Nicotinamide Riboside?

  • Healthy aging
  • Boosting cellular energy
  • Supporting metabolism
  • General wellness
  • Athletic recovery

Nicotinamide riboside (NR) is a form of vitamin B3 that the body converts into NAD+, a molecule involved in cellular energy and repair. Early human studies show it can reliably raise NAD+ levels and appears generally well tolerated, but solid evidence that it improves aging, energy, or specific health conditions is still limited. Talk with your pharmacist or doctor before starting it.
