Description of intervention(s) / exposure
Participants will take oral nicotinamide capsules twice daily in one of the 4 dosage groups for a total duration of 2 weeks:- 1500mg twice daily
2000mg twice daily
2500mg twice daily
3000mg twice daily
compliance will be ensured by capsules count at every follow up visit, blood will be collected for nicotinamide level prior to start of nicotinamide taking and then at every follow up visit.

Summary
Brief summary
We aim to determine the dose of nicotinamide (NAM) that achieves a serum level of at least 1 mM, and also to assess the effect of nicotinamide on upregulation of neutrophil function and bacterial killing in both patients with bronchiectasis and healthy volunteers.

We want to prove if nicotinamide may augment neutrophil function and enhance the killing of respiratory pathogens in patients with bronchiectasis
