Supplement Stack

Updated February 28, 2026

A supplement stack is a grouped set of ingredients chosen to work together toward one outcome architecture.

Why it matters

Composition logic matters more than ingredient count.

Core + optional model

Overlap and checks

Deconstruction example

For a sleep-support stack, separate:

Keep complexity capped by your ability to log and monitor.

Before-you-add list

Practical action step

Start with a smaller base stack and add one optional item only after 3–5 days of stable adherence.

Uncertainty and limits

Cross-site references

How this appears in Unfair

Stack composition drives safety checks, ranking, and how warnings scale with overlap and complexity.

Clinical safety note

If overlap risk rises or monitoring drops, simplify the stack before increasing dose.

Stack Goal

Stack goal is the [target outcome](/blog/complete-guide-to-supplement-stacks) you are optimizing for, such as sleep, focus, or recovery.

Dose Window

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

Recommendation Engine

The recommendation engine is the path from your inputs to [ranked suggestions](/blog/complete-guide-to-supplement-stacks), through filters and guardrails.
