Supplement context for individuals

Understand your supplement stack before changing it.

You've read the claims. Availabio shows where the evidence behind them is strong, mixed, or thin — and what questions are worth asking about timing, form, and food context.

Outputs are educational context only. Availabio does not diagnose, treat, prevent, or predict any health condition.

What Availabio shows you

Availabio doesn't tell you what to take. It shows you what the literature says about what you're already taking — and where the gaps are.

Supplement stack context

Add your current supplements and review the bioavailability parameters and evidence grades for each compound in your stack.

Timing and food context

Some compounds absorb differently with food or at specific times. Availabio surfaces relevant context from the source literature — not a recommendation, just what the data shows.

Interaction context

Review CYP pathway data for compounds in your stack that share metabolic routes. Understand what the literature covers and where the evidence is thin.

Wearable-informed context

Connect your Fitbit to add biometric context — resting heart rate, HRV, sleep, SpO2 — alongside your supplement data. View as one integrated picture.

Evidence grade per parameter

Every parameter has a source-quality grade (A–D). You can see exactly how strong the underlying data is for each compound and each specific measurement.

Curated vs. estimated, clearly labelled

Availabio distinguishes between parameters verified from primary sources and those derived from computational models. You know what you're looking at.

How to use Availabio

  1. 1

    Add your supplements

    Create a free account and add the supplements you currently take. Availabio looks up the PK parameters and evidence grades for each compound in its curated database.

  2. 2

    Review the context

    See bioavailability parameters, timing and food notes, interaction assumptions, and evidence grades for your specific stack. Understand where the data is strong and where it is genuinely limited.

  3. 3

    Connect Fitbit (optional)

    If you track with a Fitbit device, connect it to overlay resting HR, HRV, sleep stages, and SpO2 alongside your supplement data. Optional and removable at any time.

  4. 4

    Upgrade if useful

    The free tier covers core stack context. Personal Pro adds deeper CYP analysis, extended compound access, and additional biometric correlation features. Upgrade when you need more.

What the evidence grades mean

Grades describe how strong the source data is for a specific parameter — not how effective a supplement will be for you. A lower grade means the data is limited; it is not a safety flag or a clinical judgment.

A
Well-supported data

Multiple strong sources agree. The parameter estimate is as reliable as the published literature allows.

B
Good data with some variation

Reasonably strong sources, but some studies diverge. The estimate is a reasonable midpoint, not a single confirmed value.

C
Limited or indirect data

Fewer studies, smaller samples, or heavy reliance on lab-to-human extrapolation. Treat as informative context, not a hard fact.

D
Sparse or model-derived only

Very few published human studies for this specific parameter. The estimate comes from computational modeling. Useful as background context only.

Remember: Evidence grades apply to the quality of the source data for a specific measurement — not to the compound overall. A Grade C estimate for one parameter does not mean the supplement is unsafe or ineffective.
