Sound Familiar?
Niagen is built for guests who want NAD+ benefits without committing to a 2–4 hour IV session.
Energy That Won't Last
Caffeine spikes and crashes. Niagen supports the cellular machinery that actually produces sustained energy from within.
Mental Fog & Slower Focus
Brain cells need NAD+ to function. Niagen supports cognitive performance, memory, and focus at the cellular level.
Slower Recovery & Aging Signs
NAD+ levels decline with age. Niagen restores them via a more tolerable precursor pathway — cleaner side-effect profile than direct NAD+.
From Consultation to Cellular Restoration.
Every Niagen protocol at iCRYO St Johns is delivered by a licensed RN with personalized dosing.
Free Consultation
Sit down with our medical team to review your goals — energy, focus, recovery, longevity — and confirm Niagen is right for you.
Personalized Dosing
We map a starting protocol based on tolerance and goals — single session, 4-session energy package, or 8-session longevity program.
45-Minute Session
Settle into our infusion lounge. Most guests find Niagen better tolerated than direct NAD+ — fewer side effects, similar benefits.
Feel the Lift, Then Maintain
Many guests notice cleaner energy and sharper focus within the first few sessions. We adjust cadence as you go.

Is Niagen Right for You?
Niagen is for almost everyone — here's how to tell if it's a fit for you.
This IS for you if…
- You want NAD+ benefits without a 2–4 hour IV session
- You've tried direct NAD+ and want a cleaner side-effect profile
- You're focused on healthy aging, longevity, and cellular performance
- You're an athlete, founder, or high-output professional chasing recovery
- You want medical-grade Niagen administered by a licensed RN
- You're open to a short protocol series for the biggest lift
This is NOT for you if…
- You're pregnant or nursing without provider clearance
- You have a serious cardiac, kidney, or liver condition (we'll screen carefully)
- You expect one session to fix a chronic condition — Niagen is support, not a cure
- You're under 18 without parental consent
- You're not comfortable with an IV drip
- You aren't willing to commit to a starter session to gauge response
What to Expect
Your first Niagen visit, start to finish — about 45–60 minutes total.
Before Your Visit
Eat a full meal and hydrate well before your session. Wear comfortable clothes with easy arm access. Bring a laptop, book, or headphones for the session.
RN Consult & Dosing
Our nurse reviews your goals and health history and confirms the right Niagen protocol — starter, energy package, or longevity program.
Comfort-First Infusion
Settle into a private recliner. Niagen is typically better tolerated than direct NAD+ — most guests work or relax through the 45-minute session.
Feel the Lift
Most guests notice cleaner energy, sharper focus, and better sleep within the first few sessions. We adjust cadence as you go.
