NADMED laboratory works in collaboration with Anu Wartiovaara Suomalainen laboratory and operates in Helsinki, Finland. Besides serving clients the laboratory takes part in several research projects. NADMED also conducts its own research to improve the NADMED products to be as user-friendly as possible.

Ongoing projects:

  • Response of NAD metabolism to life-threatening conditions – NADs in intensive care patients
  • Role of NADs in cardiovascular diseases
  • Changes of NADs in pancreatic and gastric cancer
  • Effect of alcohol on NAD levels

Completed projects:

  • NAD metabolism in obesity
  • NAD metabolism in long Covid
  • NAD metabolism in non-alcoholic liver disease
  • NADs in pre-eclampsia


  • Validation protocols for NAD+ and NADH assay kit for cells and tissues
  • Developing a way to preserve home-collected blood during shipment time
  • Improving stability of Q-NADMED kit components for storage at -20C and shipment at ambient temperature
