What is a Longevity Supplement Stack?
A longevity supplement stack is a personalized combination of vitamins, minerals, peptides, and small molecules taken daily to support healthspan, mitochondrial function, NAD+ levels, inflammation control, and sleep quality. Popular stacks combine NAD+ precursors like NMN or NR with omega-3 fatty acids, vitamin D3, magnesium glycinate, and creatine. The Longevity Supplement Stack Tracker logs your daily intake locally in your browser, builds a streak counter, and shows a 30-day adherence heatmap so you can see consistency at a glance.
Why Tracking Adherence Matters More Than the Stack Itself
Most longevity research shows that consistency over months and years drives biomarker change — not occasional dosing. A 90% adherence rate to a simple stack will outperform a 40% adherence rate to a complex one. By logging every dose taken, you create a behavioral feedback loop: streaks reward consistency, and the heatmap exposes weeks where life got in the way. Studies on habit formation suggest 66 days of consistent action are needed to make a routine automatic. Your streak counter is the simplest measure of whether your stack is actually a stack or just a shelf.
How to Build a Sensible Stack
Start with the well-evidenced basics: omega-3 EPA/DHA (Harris 2017, PMID 28264838), vitamin D3 if you are deficient (Autier 2014, PMID 24107181), creatine for muscle and cognition (Kreider 2017, PMID 28615996), and magnesium glycinate for sleep. Add NAD+ precursors like NMN (Martens 2018, PMID 29490774) if you tolerate them. Avoid stacking more than 8 to 10 active compounds without bloodwork — the goal is signal you can measure, not a maximalist routine. Re-test biomarkers (CRP, glucose, vitamin D, omega-3 index) every 3 to 6 months.
Privacy and Data Export
Every checkbox click is saved to your browser's localStorage with a per-day key (YYYY-MM-DD). Nothing is sent to a server. Use the Download CSV button to export your full intake history for your doctor, your spreadsheet, or your own analysis. Clearing browser data will erase your log, so export periodically.
