What-Supp methodology · Version 2026.09

How a supplement earns its place

What-Supp is a decision aid for active adults. It identifies the likely gap first, checks whether a supplement fits that gap, then considers evidence, duplication, practicality and safety. It can recommend nothing.

The order matters

  1. 1

    Eligibility and safety

    Age, medication, health concerns and symptom red flags can limit or stop personalised suggestions.

  2. 2

    The foundation gap

    Training, food, protein, sleep, hydration, recovery and stimulant habits are checked before products.

  3. 3

    Evidence for this use

    Evidence is judged for the specific goal and situation, rather than assigning one universal score to an ingredient.

  4. 4

    Practical fit

    Current supplements, diet, tolerance, budget and format prevent duplicates and impractical suggestions.

Evidence tiers

Strong

Consistent evidence for a defined use when an evidence-based protocol and the right situation are present.

Promising

Useful research exists, but the effect, population, product or ideal protocol remains less certain.

Limited

Early, mixed or narrow evidence. Shown for discovery and context, never as a confident first choice.

A strong evidence label does not mean a large effect, universal benefit or zero risk. A limited label does not mean impossible; it means uncertainty should be part of the decision.

What is in the evidence library

Foundational and performance

Protein supplements, creatine monohydrate, caffeine, electrolytes, sports carbohydrate, beta-alanine, dietary nitrate and sodium bicarbonate.

Situational performance

Citrulline, essential amino acids and HMB.

Sleep and recovery

Magnesium, glycine, tart cherry and ashwagandha.

Focus and diet gaps

L-theanine, L-tyrosine, omega-3, vitamin D, vitamin B12 and iron.

Vitamin D, B12 and iron are treated as testing or professional-led questions when deficiency is plausible. They are not ranked from symptoms alone.

Core sources

The editorial framework prioritises official Australian guidance, consensus statements, systematic reviews and primary research. Claims are written conservatively and separated from product sales.

Limits and review status

What-Supp cannot diagnose a deficiency, sleep disorder, medical condition or cause of fatigue. It does not know your pathology results, complete medication list or full diet.

This release is an editorial evidence review and has not yet received independent practitioner sign-off. It remains labelled Public Beta until that review occurs.
