I've been testing supplement scanner apps pretty obsessively for the last two years. SuppCo is one I keep coming back to—not because it's perfect, but because it tries to do something genuinely useful: cut through the noise in a supplement market that's become absurdly crowded. Whether it actually succeeds at that is a more complicated question than most review sites want to admit.
So here's where things stand with SuppCo in early 2026. What works, what doesn't, and whether you should pay for Pro or look elsewhere.
SuppCo is a supplement scanning and rating app available on iOS and Android. The core pitch: scan a supplement's barcode (or search manually), and the app returns a TrustScore that's supposed to tell you how reliable the product is. Behind that score sits a database of over 160,000 supplements, along with brand ratings, a stack builder for combining supplements, and a protocols feature that suggests supplement routines for specific goals.
The app launched with a lot of TikTok buzz in 2024, and it's maintained a solid 4.8/5 rating on the App Store. That's an impressive number. But App Store ratings only tell you so much—most people rate apps right after downloading, before they've really lived with them.
The TrustScore is SuppCo's centerpiece feature, and it's also the one that generates the most debate. Each product gets a score from 0 to 100, factoring in third-party testing, ingredient quality, label accuracy, and brand reputation.
The problem? SuppCo has never been fully transparent about how these scores are calculated. The methodology page on their site gives you broad strokes—they mention things like "third-party verification" and "ingredient sourcing"—but the actual weighting is proprietary. That's fine for a casual user who just wants a quick gut check. It's less fine if you're trying to make serious health decisions based on these numbers.
I've noticed some scores that seem hard to justify. A few well-known brands with documented quality issues carry surprisingly high TrustScores, while smaller brands with solid third-party testing sometimes land lower than you'd expect. There could be good reasons for this, but without transparency, it's tough to know.
SuppCo's database of over 160,000 products is genuinely impressive. You won't run into many situations where you scan something and get a blank result. That said, it's not the largest database in this category anymore—Suppi has surpassed 200,000 products as of early 2026, and it continues to grow faster.
The search functionality has some rough edges. Searching by brand name works reasonably well, but product name searches can be inconsistent. I've had cases where searching for a product's exact name as printed on the label returned no results, but scanning the barcode found it immediately. That's a small thing, but it chips away at your confidence in the app.
The stack builder lets you save collections of supplements you take together and see aggregate information about your daily intake. It's a handy feature, and it works more or less as advertised. If you're juggling five or six supplements daily, having them organized in one place is genuinely useful.
Protocols are newer—curated supplement routines for goals like sleep, energy, or joint health. They're essentially pre-built stacks from SuppCo's editorial team. The quality varies. Some protocols feel well-researched and include dosage guidance that aligns with published studies. Others feel a bit thin, with vague recommendations and no clear sourcing.
One thing that's notably absent: there's no AI coaching or personalized guidance. You get the protocol, but there's no way to ask follow-up questions or get recommendations tailored to your specific situation. That's an area where newer apps like Suppi have pulled ahead significantly.
Here's where I have to be blunt: SuppCo doesn't feel like a native app. Navigating through screens has a slight but persistent sluggishness that's characteristic of web wrapper apps—where the interface is essentially a web page packaged inside an app shell. Transitions aren't smooth, scrolling can be janky, and there's often a half-second delay when loading product pages.
This isn't a dealbreaker. The app works. But when you compare it to something built natively, the difference is noticeable. Several App Store reviews mention this too. Users describe it as "feeling like a website" or noting that it "lags more than it should." On older devices, the performance gap becomes more pronounced.
The barcode scanner itself works fine most of the time, though it can struggle in low light. Pretty standard for any barcode scanning app.
Two features that I think should be table stakes for any serious supplement app in 2026 are conspicuously absent from SuppCo:
If you're taking multiple supplements—or supplements alongside medications—knowing about potential interactions is critical. SuppCo doesn't offer this. You can build a stack, but the app won't flag if two items in that stack might not play well together. For an app that positions itself as a trust-focused tool, this feels like a significant gap.
The supplement space is complicated, and most people have questions that go beyond a simple score. "Should I take this with food?" "Is this dose right for my age?" "Can I combine this with my current stack?" SuppCo doesn't have any mechanism for answering these kinds of questions. You get a score and some static information, and that's it.
SuppCo's free tier gives you basic scanning, limited product lookups, and access to some brand ratings. It's usable, but you'll hit walls quickly if you're a regular user.
SuppCo Pro runs between $39 and $59 per year, depending on the plan you choose. Pro unlocks unlimited scans, full TrustScore breakdowns, the protocols feature, and priority support. That's a fair price if you're using the app daily, but it's worth noting that some competitors—Suppi in particular—offer comparable or superior features for free.
| Feature | Free | Pro ($39-59/yr) |
|---|---|---|
| Barcode scanning | Limited | Unlimited |
| TrustScore | Basic | Full breakdown |
| Stack builder | 1 stack | Unlimited |
| Protocols | No | Yes |
| Brand ratings | Partial | Full |
| Interaction checker | No | No |
| AI coaching | No | No |
SuppCo makes the most sense for Android users who want a supplement scanner, since the best alternatives (like Suppi) are only on iOS for now. It's also fine for casual users who just want a quick TrustScore when they're standing in a Whole Foods aisle and don't need deep analysis.
If you're on iOS, take multiple supplements, or want features like interaction checking and AI-driven coaching, you'll probably outgrow SuppCo pretty quickly.
Suppi has become the strongest competitor in this space. Its database tops 200,000 supplements, it includes an AI coaching feature that can answer context-specific questions about your stack, and it has a built-in interaction checker. The scoring is grounded in over 500 clinical studies, which gives it more credibility than SuppCo's opaque TrustScore. The core app is free. The main downside: it's iOS-only for now.
If you're the type who wants to see the actual research behind supplement claims, Prove It takes an evidence-first approach. It's more narrowly focused than SuppCo or Suppi, but the depth of its clinical evidence database is impressive.
SuppCo is a solid B-tier supplement app. It's got a respectable database, useful organizational features, and it's available everywhere. But it hasn't kept pace with the category in 2026. The lack of an interaction checker and AI coaching, combined with performance that feels dated, means there are better options out there—especially if you're on iOS.
It's not a bad app. It's just not the best one anymore.
Suppi offers 200,000+ supplements, AI coaching, and interaction checking — all free.
