A new study published in Nature Metabolism has brought to light a new cellular membrane transporter specific to NMN. Encoded by the Slc12a8 gene, it allows NMN to become available inside the cells for direct NAD+ production. 

It’s about time that everyone who suffers from an autoimmune condition got some good news. The good news comes from researchers associated with Brigham and Women’s Hospital at Harvard Medical School.

Because the NAD+ molecule cannot readily cross cell membranes to enter cells,  precursor molecules to NAD+ - such as NMN - must be used to increase bioavailable levels of NAD+.

NMN is a derivative of the B-vitamin niacin and it dramatically improves health and longevity by serving as a precursor to NAD+.
