Most supplements ask you to trust the label. PROTOCEL hands you the lab report for the jar in your hand. That is the standard I would want for my own patients.

Why PROTOCEL
Purity is not a claim on the jar. It is a certificate for your batch.
Every production run goes to an accredited lab before it ships. What the lab finds is published against the batch number on the base of the jar.

The first twelve weeks
What to expect, week by week.
Published NMN trials measured change over eight to twelve weeks. We point you to week twelve, not day two.
Your first capsule.
You will not feel anything yet, and that is expected. NMN is not a stimulant.
The quiet week.
This is where most routines stall, because nothing tells you to wait. The research window is longer.
The window the trials measured.
Published studies measured blood NAD+ over roughly this period. Energy and sleep research is still developing.

Finally a label I can read
I looked up my batch the day it arrived and the certificate was there. 500 mg means 500 mg. That is why I switched.

Week twelve, still on the counter
Most supplements I quit by week three. The timeline on the box told me what to expect, so I kept going. Reordered both jars.

My doctor asked for the certificate
She wanted to see heavy metals and purity before I started anything. I sent the link. She said fine, carry on.

Questions
Straight answers.
If something here is unclear or missing, write to us and we will answer it properly.
NMN (nicotinamide mononucleotide) is the molecule your cells convert into NAD+, a coenzyme involved in energy production and DNA repair. Each capsule holds 500 mg, a dose studied in published human trials.
Published trials measured changes in blood NAD+ over eight to twelve weeks. NMN is not a stimulant, so there is nothing to notice on day one. We point you to week twelve.
Yes. NMN and Glycine + NAC share one morning routine but stay separate products, each with its own label, dose, evidence grade and batch certificate. Take each as directed on its jar.
Every batch is tested by an ISO/IEC 17025 accredited lab for purity, heavy metals and microbial contamination. The certificate is published against the batch number printed on the base of the jar. Look it up above.
If you take prescription medication, are pregnant or nursing, or have a medical condition, speak with your physician before starting. We would rather you asked than guessed.
