Question 1

What is the difference between NAD+ and NADH?

Accepted Answer

NAD+ is the oxidized form (ready to accept electrons), while NADH is the reduced form (carrying electrons). In research, NAD+ is the preferred form for studying cellular health and sirtuin activation.

Question 2

Why do NAD+ levels drop with age?

Accepted Answer

NAD+ levels decline due to both decreased production and increased consumption by enzymes like CD38 and PARPs, which are more active during chronic inflammation and DNA stress.

Question 3

Is NAD+ for human use?

Accepted Answer

No. Melbourne Peptides supplies NAD+ strictly for in-vitro laboratory research and analytical modeling.
