The Race to Boost NAD+

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It plays a critical role in cellular energy production, DNA repair and ageing regulation. The problem: NAD+ levels drop by ~50% between ages 20 and 60.

This is where NMN and NR come in. two precursors your body converts into NAD+. The question every biohacker asks: which one works better?

What Is NMN?

NMN (nicotinamide mononucleotide) is a direct precursor to NAD+. Your body converts it to NAD+ in a single enzymatic step. It was popularised by Dr. David Sinclair of Harvard, who has taken it personally for years.

Mechanism: NMN → NAD+ (via NMNAT)

What Is NR?

NR (nicotinamide riboside) is another NAD+ precursor, but it requires two conversion steps: first to NMN, then to NAD+. NR has more human clinical trials thanks to ChromaDex (Tru Niagen).

Mechanism: NR → NMN → NAD+ (via NRK → NMNAT)

Head-to-Head Comparison

Which Should You Choose?

For most biohackers, NMN at 500 mg/day is the preferred choice in 2026:

• One fewer conversion step (more direct)
• Increasingly competitive pricing
• Recent human studies show promising results in energy and ageing biomarkers

If you prefer the brand with the strongest clinical backing, Tru Niagen (NR) remains a solid, well-studied option.
