Interaction checker

Does the app warn you when supplements interact with each other?

None²

Third-party reviewers flag this as Suppco's biggest gap. The app catalogs and rates products but does not analyze your stack for interactions.

1,737 records documented⁴

Every pairwise interaction is in the bundled database, across 370 substances. Each one has a tier, a mechanism, and PubMed-linked citations. Visible on the Stack screen and on the free public checker at /interactions.

Prescription cross-check

Does the app flag interactions between your supplements and your medications?

None²

Suppco is supplement-only. It does not model prescription drugs, so it cannot tell you that your supplement might affect your statin, blood thinner, or thyroid medication.

206 prescriptions⁴

Statins, anticoagulants, antidepressants, blood pressure, diabetes, thyroid, and more. Cross-check happens automatically when both are in your stack.

Citations per claim

Can you click any score or recommendation and see the studies behind it?

Proprietary score, no per-claim cites¹²

TrustScore aggregates 29 attributes with undisclosed weighting. Suppco's site lists studies in a "research center," but individual product scores do not surface the math or the source.

4,652 source links⁴

Every interaction, every supplement profile, every protocol step shows its sources, almost all linked to PubMed by PMID. Browse the library.

Methodology transparency

Can you read how the score is actually computed?

Proprietary algorithm¹

Suppco describes 29 TrustScore attributes but does not publish the weighting, the formula, or how a score changes when one attribute moves. Black box.

Published in full⁴

Base 70. +2 per synergy. −5 per caution. −10 per conflict. −25 per contraindication. Clamped 0–100. Read the methodology.

Ownership & conflicts of interest

Who owns the company, and what else do they sell?

Owned by Function Health³

Function Health, the blood-testing company co-founded by Mark Hyman, MD, acquired Suppco. Hyman is also one of Suppco's featured doctors. Vertical integration between the platform and the products being rated.

Independently owned

No manufacturer payments. No affiliate programs. No house brand. The app subscription is the only revenue. Independence policy.

AI advisor

Can the app answer "is my stack safe for me" with a context-aware reply?

No AI coaching²

Suppco serves static product info and protocol pages. Users cannot ask context-specific questions about dose, timing, or combination safety.

Six stack-aware AI modes

Stack Analyzer, Timing Optimizer, Safety Scanner, Goal Coach, Wellness AI, and general advisor. Answers cite the studies behind each recommendation.

iOS app quality

Native iPhone app or web wrapper?

Web-wrapper feel²

Reviewers describe the iOS app as feeling like a web wrapper with janky scrolling, loading delays on product pages, and worse performance on older devices.

Native Swift / SwiftUI

Built for iPhone from the ground up. Smooth scrolling, instant tab switches, full SwiftData persistence, App Attest hardened.

Pricing

What costs what?

$39.99–$59.99 / year²

Free tier covers basic scanning and limited lookups. Pro unlocks unlimited scans, full TrustScore breakdowns, and protocols.

$6.99 / mo or $49.99 / yr

Free includes Stack Score, full interaction checker, and source citations. Pro adds AI advisor, timing optimization, full protocol customization, export, and analytics.

Catalog breadth

How many products in the database?

160,000+ products¹

Suppco's product catalog is its biggest strength. Barcode scanning works against a deep retail database.

164 supplements + 206 prescriptions

We focus on depth per substance, not catalog volume. Each entry has a full profile, evidence tier, dosing range, mechanisms, and pairwise interactions.

Where they win

Honest about Suppco's strengths.

A useful comparison admits where the other side is better. Here is ours.

Bigger product catalog. 160,000+ scannable products beats 164 supplement entries on raw count. If you want to scan a random bottle off a shelf and get a brand-quality rating, Suppco is the deeper catalog.
Cross-platform. Suppco has an Android app. NutriStack is iPhone-only at launch. If you need both platforms, this matters.
Brand TrustScores cover 500+ brands. If brand-quality scoring is the single feature you care about most, their library is larger than the 96 brands NutriStack rates at launch.

Where each app fits depends on the problem you are solving. If yours is "is my stack safe and is each claim sourced," NutriStack is built for that. If yours is "scan and rate every bottle in the store," Suppco has more catalog to scan.

Bottom line

If you are choosing between them.

Choose Suppco if

You want to scan barcodes against the largest possible product catalog
You trust Mark Hyman and other functional-medicine practitioners as your evidence filter
You are on Android and want a cross-platform option

Choose NutriStack if

You want every score and claim to link to the study behind it
You want to know if your supplements interact with each other or your medications
You want a published methodology, not a proprietary score
You want an iPhone app, not a web wrapper
You want the product you use to be independently owned
