Dose Window

Updated February 22, 2026

A dose window is the acceptable intake band for a dose, not the same as a fixed clock slot.

Why it matters

Using windows instead of exact times improves practical adherence while preserving comparability across lifestyles.

Window vs fixed time

• Window: flexible intake with a front and back tolerance band.
• Fixed-time behavior: best for compounds with narrow pharmacokinetics or highly time-sensitive effects.

Minimum viable adherence margin

A practical margin is a small tolerance band that still preserves outcome signal.

If misses are frequent, widen by only one step after reassessing outcomes and safety context.

Timezone behavior

When timezone changes occur, Unfair typically maps windows to your current wake and sleep context rather than rigid clock carryover.

Example applications

• Fat-soluble nutrients: morning window often works better with food and fat for consistency.
• Stimulants: generally avoided in evening windows to reduce sleep drift.

Cross-site references

• Dose logging
• Morning dose window
• Evening dose window

Uncertainty

• Evidence is limited on exact window width for all compounds.
• Evidence is limited on how quickly travel-induced shifts impact long-tail effects.

How this appears in Unfair

Unfair uses windows to rank compliance and expected response with context-specific flexibility before applying hard escalation rules.

Clinical safety note

If window drift creates repeated dosing confusion or overlap, reduce complexity and pause risky additions.
