Evidence grading
Every supplement claim assessed against the published research, with the strength of evidence stated plainly — including when evidence is weak or absent.
Research-stage · Early validation
Supplement decisions deserve evidence. Not influencers.
HERA is a research-stage platform exploring how scientific evidence and biomarker context could make supplement decisions more transparent. We're inviting early users to help decide which problems and evidence workflows deserve to be developed further.
HERA is in early validation and does not provide medical advice.
The problem
The supplement market runs on claims. Rarely on evidence.
Millions of people spend real money on supplements every month. Yet most decisions are shaped by influencer opinions, sponsored content, marketing claims, and contradictory headlines — not by the underlying research.
The result: it is genuinely hard to answer basic questions.
- How strong is the evidence behind this supplement — actually?
- Does the research apply to someone like me?
- What do my blood values say about whether this is even relevant?
- Which claims are supported, and which are marketing?
The science exists. It's just buried under noise. Nobody has time to read 400 studies before buying a vitamin.
What we're building
An evidence-based supplement intelligence platform.
HERA's goal is to translate scientific literature into clear, graded, transparent educational insights — and, where users choose to share it, to put that evidence in the context of their own biomarker data.
Biomarker context
Educational insights that relate published reference ranges and research findings to lab values users choose to share.
Full transparency
Every insight linked to its underlying sources. You can always see why, not just what.
No products to push
HERA does not start from a shelf of supplements to sell. It starts from the evidence.
HERA provides educational information to discuss with a qualified professional. It does not diagnose, treat, cure, or prevent any condition, and does not replace medical advice.
An early look
What an educational insight could look like.
Illustrative mock-ups from our concept work, using placeholder data. Not real recommendations — every element shows current level, a published target range, and the strength of the evidence behind it.
BIOMARKER · EDUCATIONAL EXAMPLE
Vitamin D (25-OH)
24ng/mL
0ref. interval 30–60100
Published reference intervals vary by laboratory and population.
Educational insight — not medical advice. Discuss your results with a qualified professional.
BIOMARKER · EDUCATIONAL EXAMPLE
Magnesium (serum)
0.84mmol/L
0.5ref. interval 0.75–0.951.2
Serum magnesium reflects only part of total body status, a known limitation discussed in the literature.
Educational insight — not medical advice. Discuss your results with a qualified professional.
EVIDENCE GRADE · EDUCATIONAL EXAMPLE
Creatine
Cognitive performance
Moderate
Based on 27 published studies reviewed
Multiple randomized trials; mixed results in well-rested adults; effect sizes small to moderate in specific contexts.
Evidence grades summarize published research. They are not medical advice.

Educational illustration with placeholder data. "Cited interval" refers to published, population-level reference values, which vary by laboratory. Discuss any results with a qualified professional. This is not a diagnosis.
SUPPLEMENT CONTEXT · EDUCATIONAL EXAMPLE
Omega-3 (EPA/DHA)
Research on omega-3 intake may be more relevant to people with low dietary fish intake. Published studies vary widely in dose, duration, and population.
Educational insight — not medical advice. Whether any supplement is appropriate for you is a question for a qualified professional.
SUPPLEMENT CONTEXT · EDUCATIONAL EXAMPLE
Magnesium (glycinate, citrate, oxide)
Published studies use different magnesium forms and doses, which complicates direct comparison. Absorption research may be relevant when reading study results.
Educational insight — not medical advice. Whether any supplement is appropriate for you is a question for a qualified professional.

How it works (research phase)
Four steps. Zero hype.
01
Share your goals
Tell us what you're optimizing for — longevity, cognition, recovery, general health — and how you currently decide what to take.
02
Understand the evidence
We show you how HERA grades and explains the research behind common supplements, in plain language with sources attached.
03
Optionally share lab context
Selected research participants may choose to share recent blood test values. Entirely optional, never required.
04
Receive educational insights
Some participants may receive an experimental, personalized educational report — a prototype built to learn from your feedback, not to advise you.
Research participation
Help us decide what deserves to be built next.
HERA is validating assumptions and evidence workflows rather than selling certainty.
- Selected early participants may be invited to a free 15-minute research interview.
- Some participants may be invited to review experimental educational concepts based on the goals and context they choose to share.
- No medical advice is provided. Reports are educational prototypes.
- No result is guaranteed. This is research, and honest research includes finding out what doesn't work.
- The purpose is simple: understand what supplement users actually need, and improve the concept — or discard the parts that don't hold up.
If you've ever stood in front of a supplement shelf wondering what the evidence actually says: you're exactly who we want to talk to.

Built on trust, or not at all.
We never sell individual health data
Not now, not later, not “anonymized to partners.”
Privacy first
You decide what to share. Sharing lab values is always optional. You can request deletion of your data at any time.
No diagnosis
HERA does not and will not diagnose conditions.
No treatment recommendations
We explain evidence; we do not tell you what to take.
Scientific transparency
Every insight links to its sources. Uncertainty is stated, not hidden.
Evidence grading
Where research is weak, we say so — including for popular supplements.
