Excellent pen system and good price
“I’ve been using NaD Clinic for over a year. The new pen system is so much easier to use than the do your own needle system. The price is competitive and the company responds quickly and fairly if anything goes wrong with delivery. I trust them.”

The science
Why NAD+ matters
NAD+ is a molecule naturally present in every cell. It plays a central role in cellular energy and supports processes involved in repair, metabolism and the body’s daily rhythms.
01
Cellular energy
NAD+ helps your cells convert nutrients into usable energy.
02
Repair and resilience
It’s used by enzymes involved in DNA repair and normal cellular maintenance.
03
Sleep and circadian rhythm
NAD+ is closely connected with the cellular clock that helps regulate daily rhythms.
04
Focus and cognitive energy
The brain is highly energy dependent, and NAD+ supports the pathways that help meet that demand.
Research into NAD+ is ongoing. Use the Smart Pen under the guidance of a qualified healthcare professional.
