About Substrate

The source that isn't selling you anything — and shows you the gap between what's trending and what's true, for your situation.

The problem

People making supplement decisions live in an information environment that is structurally against them: personalized to no one, organized around what sells, and impossible for a non-expert to adjudicate. Reference sites have evidence but not belief or personalization; interaction checkers have a sliver of context; social platforms are pure unverified belief; general AI improvises across all of it with poor grounding.

The four layers

Substrate holds all four at once and composes them into one answer, with the seams visible:

• Evidence — what is true? Graded claims with provenance and certainty.
• Belief — what is thought true, and how far from the evidence? The hype-vs-evidence gap.
• Person — true for whom? A session-scoped lens (life stage, medications, goals), never a stored dossier.
• Time — true when? Momentum, hype position, and a feed of what changed.

The value is the composition — holding all four and showing the seams — not any single layer.

What we will and won't do

• We show our work: every claim has a reachable grade and source; every answer can explain why you're seeing it.
• We never bury safety beneath a benefit, and we route to a clinician when stakes or uncertainty are high.
• We don't sell supplements and take no product money.
• We are decision-support, not a doctor. Not medical advice; not a medical device. See the methodology.
