NR Research Guide

Full name: Nicotinamide Riboside

A form of vitamin B3 and a precursor to NAD+. Like NMN, it is used to raise NAD+ levels to support energy metabolism and healthy aging, with a well-studied oral safety profile.

How NR Works

Converted to NMN and then NAD+ via the salvage pathway (NRK enzymes). Higher NAD+ supports sirtuins, DNA repair, and mitochondrial energy production.

Dosing Protocol

• Typical dose: 250-1000 mg per day
• Frequency: Once daily
• Duration: Ongoing
• Route: Oral

Reported Benefits

• Raises NAD+ levels
• Supports mitochondrial energy
• Well-studied oral safety
• Studied for metabolic and cardiovascular health

Potential Side Effects

• Generally well tolerated
• Mild nausea or flushing (uncommon)
• GI upset at high doses
