Has anyone tested NAD+ blood levels yet?

Deb63  How does one do so? AFAIK there are no simple clinical tests (e.g. blood) available yet. 

A new company, Longevity Bridge, should have an NAD+ test available soon. They will also be testing for many NAD+-related metabolites (and, later, many other things).

Keep an eye on their website for availability:
