NAD+
Cellular energy, focus & recovery. The coenzyme that powers your cells.
Energy
Tired of being tired?
Low energy isn't just about sleep. As NAD+ levels and mitochondrial output decline with age, everything from workouts to workdays gets harder. Physician-prescribed therapies can help support the systems that generate it.
- Clinician-matched protocols for fatigue & low stamina
- NAD+, MIC+B12 and more — shipped in days
- Weekly care-team check-ins included
What's going on
Why energy fades with age
Cellular energy is produced in your mitochondria, and the process runs on a coenzyme called NAD+. Both decline steadily from your thirties onward — and the effect compounds with stress, poor sleep, and metabolic slowdown.
01
NAD+ decline
Levels fall significantly between your 40s and 60s. Less NAD+ means less efficient conversion of food into usable energy.
02
Mitochondrial slowdown
Fewer, less efficient mitochondria mean you fatigue faster and recover slower — the "I used to bounce back" feeling.
03
Sleep & recovery
Growth-hormone release during deep sleep declines with age, so nights feel less restorative even when you get your hours.
04
Metabolic drag
Insulin resistance and blood-sugar swings create the afternoon crash cycle that caffeine only masks.
