The supplement industry is a $65 billion market in the U.S. alone. The FDA doesn't approve supplements before they're sold. Most products aren't third-party tested. So it shouldn't be surprising that a new category of app has emerged to help consumers figure out what they're actually putting in their bodies.
We downloaded and tested every major supplement scanner and tracker app available in early 2026. We scanned the same 15 products across each app, evaluated the depth and accuracy of their analysis, tested their databases, and assessed the overall experience. Here's what we found.
| App | Primary Use | Database Size | Barcode Scan | Clinical Evidence | Free Tier | Platform |
|---|---|---|---|---|---|---|
| Suppi | Scanning + Analysis | 200,000+ | Yes | 500+ studies | Yes | iOS |
| SuppCo | Brand Reviews | 50,000+ | Yes | Moderate | Yes | iOS, Android |
| Prove It | Evidence Analysis | 30,000+ | Limited | Strong | Partial | iOS |
| Fullscript | Dispensing + Tracking | Large (practitioner) | No | Moderate | Yes | iOS, Android |
| SuppTrack | Intake Tracking | N/A | No | Minimal | Yes | iOS, Android |
| NutriScan | Nutrition Scanning | 80,000+ | Yes | Basic | Partial | iOS, Android |
What it does: Suppi is a dedicated supplement scanner that analyzes products across multiple dimensions — ingredient quality, clinical evidence, dosing adequacy, safety, and label transparency. You scan a barcode or search by product name, and the app returns a detailed breakdown of every ingredient with scores.
What stood out: The depth of analysis was noticeably ahead of the other apps we tested. Suppi didn't just identify ingredients — it evaluated the specific forms (distinguishing methylcobalamin from cyanocobalamin, for instance), checked doses against clinical research, and flagged potential concerns. The database draws on more than 500 peer-reviewed studies, and the scoring methodology was transparent.
When we scanned a popular magnesium supplement, Suppi correctly identified that it used magnesium oxide (low bioavailability), noted the dose was within safe limits but flagged the form as suboptimal compared to better-absorbed alternatives, and provided a transparency score based on the label's completeness. That level of nuance was rare across the apps we tested.
The product database covers over 200,000 supplements, which was the largest we encountered. Even niche products from smaller brands were findable. The barcode scanner worked reliably in our testing — 14 out of 15 products scanned successfully on the first attempt.
Limitations: iOS only as of February 2026. No Android version yet. The free tier provides basic scanning, with more detailed analysis available through a subscription.
Best for: Anyone who wants a thorough, evidence-based evaluation of a supplement before buying or taking it.

What it does: SuppCo takes a brand-centric approach. Rather than just analyzing individual products, it evaluates supplement companies as a whole — looking at manufacturing practices, certifications, transparency, sourcing, and reputation. You can search by brand to see an overall company rating and then drill down into specific products.
What stood out: The brand-level analysis adds context that product-only scanners miss. Knowing that a company has a history of FDA warning letters, or conversely that they publish all their COAs and use third-party certified facilities, changes how you interpret what's on the label. SuppCo aggregates this information in a way that would take significant research to compile manually.
The product scanning capability is solid, covering around 50,000+ products. It identifies key ingredients and provides quality assessments, though the clinical evidence layer isn't as deep as Suppi's. Where SuppCo shines is in its comparative features — you can compare brands side by side and see how different products in the same category stack up.
Limitations: The brand database is growing but doesn't cover every supplement company yet. Smaller and newer brands sometimes aren't in the system. The product-level ingredient analysis, while useful, doesn't go as deep into dose-response evidence as specialized scanner apps.
Best for: People who want to evaluate a brand holistically before committing to their products.
What it does: Prove It focuses heavily on the scientific evidence behind supplement ingredients. Its core value proposition is answering the question: does this ingredient actually work for what it claims? It maps ingredients to clinical trials and systematic reviews, providing evidence grades for specific health claims.
What stood out: The evidence analysis is rigorous. Prove It doesn't just say "ashwagandha may support stress" — it shows you the specific studies, sample sizes, outcomes, and evidence quality ratings. For anyone who wants to go beyond marketing claims and understand what the research actually says, this is the most research-forward app in the category.
The approach is refreshingly honest. Ingredients with weak evidence get low ratings regardless of how popular they are. We appreciated that it didn't inflate scores to make products look better than the science supports.
Limitations: The database is smaller than Suppi's (around 30,000+ products), and the barcode scanning functionality was less reliable in our testing. The interface is more academic than consumer-friendly — if you don't have a basic understanding of clinical research terminology, some of the analysis can feel dense. Also primarily iOS at this point.
Best for: Science-minded consumers and healthcare practitioners who want to evaluate ingredients based on research quality, not marketing.
What it does: Fullscript is primarily a supplement dispensing platform used by healthcare practitioners (naturopaths, functional medicine doctors, dietitians) to recommend and sell specific supplement products to their patients. The consumer-facing app allows you to browse professional-grade supplements, follow your practitioner's recommendations, set up auto-ship, and track your supplement routines.
What stood out: The product catalog is extensive and skews heavily toward practitioner-grade brands (Thorne, Pure Encapsulations, Designs for Health, etc.) that aren't always available in retail stores. If you work with a healthcare provider who uses Fullscript, the integration between their recommendations and your ordering is seamless.
The educational content within the app is solid, with ingredient monographs and protocol guides. The platform also provides some analytical tools for practitioners to evaluate products.
Limitations: Fullscript isn't really a scanner app. You can't scan a random bottle off a store shelf and get an independent analysis. It's a purchasing and tracking platform first. There's also an inherent conflict of interest: Fullscript makes money when you buy supplements through their platform, which means their product recommendations aren't fully independent. They're recommending from their own catalog. It doesn't have barcode scanning for third-party products.
Best for: People who already work with a healthcare practitioner and want a streamlined way to purchase and manage recommended supplements.
What it does: SuppTrack is a straightforward supplement tracking app. It helps you log what you take, when you take it, and reminds you of your daily routine. You can add supplements manually, set dosing schedules, and track adherence over time.
What stood out: It does one thing and does it well. If your primary need is remembering to take your supplements and keeping a record of what you've taken, SuppTrack's interface is clean and frictionless. The reminder system is customizable and reliable. You can set different schedules for different supplements (daily, every other day, cycling protocols, etc.).
Limitations: SuppTrack doesn't analyze supplement quality, check ingredient evidence, or scan products. It's purely a logging and reminder tool. There's no product database, no clinical evidence integration, and no quality scoring. You could be diligently logging a terrible product and the app wouldn't flag it. It complements a scanner app but doesn't replace one.
Best for: People who already know what they want to take and need help with consistency and tracking.
What it does: NutriScan is a broader nutrition scanning app that covers food products, beverages, and supplements. It uses barcode scanning to pull up product information, nutritional data, and ingredient analysis. For supplements, it provides basic ingredient identification, allergen flags, and a general quality score.
What stood out: The broad coverage means you can use one app for both food and supplement scanning. The barcode database is large (80,000+ products including food), and the scanning was reliable. The allergen and additive flagging is useful for people with dietary restrictions.
Limitations: Because NutriScan covers food and supplements, neither category gets the depth of treatment that a specialized app provides. The supplement analysis is relatively surface-level: it identifies ingredients and flags obvious issues (artificial colors, common allergens) but doesn't evaluate clinical evidence, dosing adequacy, or ingredient form quality. When we scanned the same products through NutriScan and Suppi, the difference in analytical depth was significant.
Best for: People who want a general-purpose nutrition scanner that also covers basic supplement analysis.
After testing all of these, a few evaluation criteria stood out as most important:
Does the app actually check ingredients against peer-reviewed research? Or does it just list what's on the label without evaluating whether it works? The best apps in this category (Suppi, Prove It) cross-reference ingredients with clinical trials and provide evidence-based assessments. Apps that just regurgitate label data aren't adding much value over reading the bottle yourself.
An ingredient being present and an ingredient being present at an effective dose are two very different things. The best apps flag when doses fall below clinically studied ranges. This is particularly important for multi-ingredient products where everything looks impressive on the label but the individual amounts are too low to matter.
Does the app distinguish between magnesium oxide and magnesium glycinate? Between folic acid and methylfolate? Ingredient form significantly impacts bioavailability and effectiveness. Apps that ignore this distinction miss a critical quality signal.
An app is only useful if it can find your product. Database size matters, especially if you use niche brands or newer products. Suppi's 200,000+ product database was the largest we tested and the most likely to have what you're looking for.
Does the app sell supplements? If so, there's an inherent tension between objective analysis and driving purchases. Apps that don't sell products (Suppi, Prove It) can provide truly independent assessments. Platforms that combine analysis with a storefront (Fullscript) need to be evaluated with that bias in mind.
Barcode scanning should work quickly and accurately. In our testing, Suppi and NutriScan had the highest scan success rates. Apps with unreliable scanning create friction that defeats the purpose of using a scanner in the first place.
For most people: Start with Suppi. It has the largest database, the deepest analysis, and the best balance of accessibility and rigor. If you only download one supplement app, make it this one.
For brand evaluation: Pair Suppi with SuppCo to get both product-level and brand-level insights. Understanding a company's track record adds valuable context to individual product scans.
For research deep-dives: Prove It is excellent for anyone who wants to see the actual studies behind ingredient claims. It's the most academically rigorous app in the category.
For tracking: Add SuppTrack or your phone's built-in reminder app for daily adherence. No scanner app replaces the value of actually taking your supplements consistently.
The supplement scanning category is young and growing fast. Two years ago, most of these apps didn't exist. The fact that consumers now have tools to independently evaluate products — rather than relying solely on marketing claims and store-shelf placement — is a meaningful shift for an industry that has historically operated with minimal accountability.
Suppi scans 200,000+ supplements for safety, efficacy, and transparency scores backed by 500+ clinical studies.
