Methodology
Most supplement quizzes are sales funnels that harvest your health data. Almavivo is different: it runs in your browser, keeps your answers on your device, screens for safety first, weighs the evidence honestly, and tells you when a supplement isn’t worth it for your profile.
Local-first by design
Every answer, lab value, and generated plan stays in your browser. The recommendation engine runs on your device — not on a server we operate. Data only leaves your device when you choose to export or share at the end of the flow.
Evidence over enthusiasm
Every supplement we recommend has published human evidence behind it. Each item shows its evidence tier and links to the underlying source so you can read it yourself.
Honest about uncertainty
Most supplements have smaller effects than the marketing suggests. We label effect size honestly — modest, moderate, promising, or mixed — instead of treating every option as a breakthrough.
Safety first, always
Pregnancy, blood thinners, kidney or liver history, thyroid and autoimmune conditions, and medication load all change what's safe to recommend. We screen for these before we score anything.
A routine you'll actually keep
We aim for a simple morning pack and a simple evening pack. A stack that fits two moments a day is one you'll still be doing in three months.
Personalised, not generic
Every supplement on your list is tied to something specific you told us — a goal, a symptom, a lab result, a lifestyle factor. If we can't explain why it's on your list, it doesn't go on your list.
Evidence tiers
Every supplement in your report carries a tier so you can see at a glance how strong the evidence behind it is.
Tier A — Strong evidence
Multiple high-quality human RCTs and meta-analyses converge on a clear benefit. Effect sizes are well-replicated.
Examples: Creatine monohydrate, iron in deficiency, B12 in deficiency, plant sterols for LDL.
Tier B — Reasonable evidence
Supportive human trial data with some inconsistency or narrower indications. We're confident enough to recommend in the right context.
Examples: Magnesium, omega-3 EPA/DHA, melatonin for sleep onset, riboflavin for migraine, lavender (Silexan) for anxiety.
Tier C — Narrow or mixed evidence
Smaller trials, narrower use cases, or mixed results. Useful in specific contexts; not blanket recommendations.
Examples: L-theanine, citicoline, glycine for sleep, taurine, MSM, NAC.
Tier D — Traditional or emerging
Long history of human use but limited modern RCT evidence. We'll surface them as options to explore, not as pillars of a regimen.
Examples: Reishi, holy basil, schisandra, eleuthero, lion's mane.
What we exclude
We’re explicit about what we won’t list and why — zeolite, colloidal silver, MMS, glandulars, and other products that don’t meet our evidence or safety bar.

Every safety check the engine runs — drug classes, conditions, allergies, life stage — with the supplements excluded or routed to clinician review because of it. Generated from the rules so it can’t drift from what actually runs.

Every question in the intake, every supplement rule, every excluded item with reasoning, every safety guard — published under Apache 2.0 at github.com/almavivo/open-health-engine. Editorial decisions in this codebase are public artifacts. If you find a mistake, open an issue. If you have evidence we should be using, open a PR with the citation. The repo includes a clinician-review PR template that asks for the DOI / PMID and a conflict-of-interest disclosure.
Important
Almavivo is an educational tool, not medical advice. If you take prescription medication, are pregnant or breastfeeding, or have a chronic health condition, talk to a qualified clinician before starting any new supplement.
