Supplement context

Supplement tracking should be simple and private.

daygauge has no supplement module, but you can log each supplement as a custom habit in Quick Log and compare those days with your sleep and training. It does not recommend supplements or doses.

The question

Start with what your own data can show.

Supplement searches are huge because people want energy, sleep, strength or focus shortcuts.

daygauge is not a supplement coach. What it offers is a private log: what you took, when, and what else moved in your sleep and recovery.

Quick answer

Log each supplement, such as creatine, omega-3, vitamin D or magnesium, as a custom habit in Quick Log. daygauge shows those days beside your sleep, movement and heart readings. It does not read lab results.

Questions answered

In daygauge

How the app handles this.

Signal
daygauge gives no dosing, deficiency, fertility, hormone or treatment advice, and makes no heart-health claims.
Confidence
Missing readings lower confidence instead of creating false certainty.When a reading is not available, daygauge says so rather than filling the gap.
Weekly Review
Weekly Review shows what changed, what moved with it and whether the pattern repeated.Your first Weekly Review is free. Later reviews are part of Pro.
Illustrative example

What this can look like in the app.

Example: you logged creatine on 5 training days. Your steps, exercise minutes and sleep are shown beside them.

Example
Confidence

Confidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.

Next move

Try one small change, log it, then see whether the pattern repeats over the next week.

Example 1

Example: you started vitamin D on a date you noted yourself. daygauge does not import lab results, so any test is for you and a clinician to interpret.

Example 2

Example: you logged magnesium in the evening on 4 nights. Any sleep change stays at hunch level until it repeats.

Research

Further reading.

These studies describe groups of people. They help explain the topic, but they cannot tell you what will happen to you.

Research context only. daygauge does not diagnose, treat, prevent or predict disease risk. Personal medical concerns belong with a qualified clinician.

Limits

What daygauge does not do.

  • It does not diagnose, treat or prevent disease, or predict your risk of it.
  • It does not claim one habit caused a result. It shows the pattern, how confident it is and what else changed.
