What Is Niagen?

Niagen is nicotinamide riboside (NR), a form of vitamin B3. It's an NAD+ precursor, meaning your cells convert it into NAD+.

Think of it this way:

NAD+ therapy delivers the finished product
Niagen delivers the building block so your cells can make it themselves

How Niagen Works

Your cells take it up
Cells convert NR into NAD+ through a natural pathway
NAD+ supports cellular energy and repair

Why Niagen Has Gotten So Much Attention
