NMN Side-Effect Tracker

Free Malaysian NMN side-effect tracker. Log dose, energy, sleep, mood, and side effects in this browser only - no signup, no email capture. Export a simple record for a doctor or pharmacist discussion.

Your data stays in this browser profile. Entries are saved in localStorage on this browser/device only. We never see your data and we do not have an account system. localStorage is not encrypted; anyone using the same browser profile may be able to see your notes. Closing this tab does not delete data; clearing browser storage does.
Not for emergencies. Do not use this tracker during severe or rapidly worsening symptoms. If you have breathing difficulty, facial or throat swelling, chest pain, fainting, severe abdominal pain, persistent vomiting, severe mood changes, unusual bleeding, or any symptom that feels urgent, stop using the supplement and seek urgent medical care.

What to discuss with your doctor

Bring your CSV export to your next GP, pharmacist, or specialist visit as a discussion record. The patterns most worth flagging: persistent headache or fatigue beyond 2 weeks, sleep disruption, any unusual bruising or bleeding (especially if on anticoagulants), GI distress that escalates rather than resolves, and any perceived change in metabolic symptoms that needs lab confirmation.

What this tracker does NOT do

This is a personal log, not a medical device. It does not diagnose adverse drug reactions, predict outcomes, or replace clinical evaluation. For non-emergency questions, see our safety guide or Q&A library.
