Frequently Asked Questions
What's the difference between NMN and NR?
Both are NAD+ precursors. NMN (nicotinamide mononucleotide) is one step closer to NAD+ in the biosynthesis pathway. Both are effective, with NMN showing promising results in recent human trials.
When should I take NAD+ supplements?
Most longevity researchers recommend taking NAD+ precursors in the morning, as they may affect circadian rhythm and energy levels.
At what age should I start longevity supplements?
NAD+ levels begin declining in your 30s. Many experts suggest starting NAD+ support in your late 30s to 40s, though younger individuals may benefit during high-stress periods.
