NAD+ is a crucial coenzyme found in every cell, involved in energy generation and cellular maintenance that naturally declines with age. Supplementation may support cellular health, boost energy, enhance cognitive function, and promote longevity through multiple delivery methods.
Direct delivery to bloodstream ensures maximum cellular availability for energy production via ATP synthesis, DNA repair through PARP activation, and sirtuin-mediated longevity pathways. Supports mitochondrial function and metabolic homeostasis.

Frequently Asked Questions
Why does NAD+ need to be injected instead of taken as a pill?
While oral NAD+ precursors (NMN, NR) are available and better absorbed than direct NAD+, injectable forms achieve 100% bioavailability and immediate cellular uptake. IV NAD+ bypasses the digestive system entirely, making it ideal for rapid energy restoration and those wanting guaranteed delivery.
Can I take NAD+ if I drink alcohol regularly?
No. Alcohol significantly reduces NAD+ levels and severely reduces the therapy's effectiveness. You should avoid alcohol during NAD+ treatment. If you drink regularly, consider addressing that habit first for maximum therapeutic benefit.
How long do the energy benefits of NAD+ last?
With IV NAD+, energy improvements typically appear within 1-2 weeks initially. However, the benefits build over time—by weeks 9-12, you'll see optimized metabolic function and sustained energy. Oral precursors take longer (weeks 5-8+) but provide continuous support when taken daily.
Does NAD+ actually reduce aging, or just make you feel more energetic?
NAD+ addresses aging mechanisms directly by activating sirtuins (longevity enzymes) and supporting DNA repair via PARP activation. However, it's not a fountain of youth—it optimizes cellular maintenance. Combined with healthy habits, NAD+ may help with appearance and age-related decline, but results vary individually.
