Let's talk about the elephant in the room with Fullscript. It's a supplement store. A very nice, well-organized, practitioner-connected supplement store. But a store nonetheless.
Fullscript makes money when you buy supplements through their platform. Practitioners who use Fullscript earn commissions on the products their patients purchase. The entire system is designed to move product. And when the platform giving you "recommendations" profits from those recommendations, you should at least pause and think about what that means for the quality of the advice.
I'm not saying Fullscript is dishonest. The brands they carry are generally reputable. The practitioner recommendations are often sound. But there's a structural problem with getting your supplement analysis from a company whose revenue depends on you buying more supplements.
Suppi doesn't sell supplements. Doesn't earn commissions. Doesn't have affiliate relationships with brands. It analyzes what you're taking — or thinking about taking — and tells you whether the evidence supports it. That's it. The business model is the app, not the products.
Fullscript is a B2B2C platform. Here's the flow:
It's a clean, well-executed business. The user experience is smooth. The product selection is large. The brands are generally good. If your practitioner uses Fullscript and you trust them, you'll probably be fine buying through the platform.
But notice what's absent from that flow: independent analysis. Nobody in the chain has a financial incentive to tell you that you don't need a supplement, that a cheaper product is equally effective, or that the ingredient in a pricier formulation doesn't have better evidence than the budget version. The system is built to dispense, not to evaluate.
This matters more than people think. The supplement industry has a long history of overpromising and underdisclosing. Products with inadequate doses. Proprietary blends that hide exact amounts. Ingredient forms chosen for cost rather than efficacy. Labels that technically aren't wrong but are designed to mislead.
When the tool you use to evaluate supplements has skin in the game, you lose the most valuable thing an analysis tool can offer: objectivity. Fullscript will happily show you hundreds of products. It will tell you what practitioners recommend. What it won't do is tell you that a $15 product from a brand they don't carry is essentially identical to the $45 product in their catalog.
Suppi has no catalog. No store. No checkout page. Its only job is to tell you whether what you're looking at is worth your money based on clinical evidence, ingredient quality, and dose adequacy. If the answer is no, the app says no. There's no revenue to protect.

These are fundamentally different products solving different problems. Fullscript is a purchasing platform. Suppi is an analysis platform. The question is whether you want the tool that helps you buy or the tool that helps you evaluate.
The most valuable advice a supplement analysis tool can give you is "skip this one." Suppi does this regularly. Scan a product with underdosed ingredients and low evidence, and the app will tell you clearly. There's no financial reason to sugarcoat the results.
Fullscript doesn't have a "don't buy" signal. Products in their catalog are there to be sold. The absence of negative signals isn't the same as a positive endorsement, but that distinction is lost on most users who interpret availability as implicit approval.
Fullscript carries products from over 350 brands. That sounds like a lot. But there are thousands of supplement brands on the market. If you're buying from Costco's Kirkland line, Amazon's Solimo brand, or any number of smaller manufacturers, those products don't exist in Fullscript's world.
Suppi's database covers 200,000+ products across the entire market. It's not limited to brands that have distribution agreements with a particular platform. You can scan literally anything and get an analysis.
When a Fullscript practitioner recommends Product A, the implicit comparison set is other products in the Fullscript catalog. Maybe Product A is the best option among what they carry. But maybe a product they don't carry is equally effective at half the price. You'd never know.
Suppi doesn't have a catalog to protect. Scan any two products from any two brands bought anywhere and compare them side by side on the same evidence-based criteria. The tool doesn't care where you buy. It cares whether what you buy is worth taking.
I want to be fair about this. Fullscript isn't some sketchy operation. It serves a real purpose.
The problem is when people use Fullscript as their source of truth for whether a supplement is good. That's not what the platform is designed to do. It's designed to sell. Those are different jobs.
The people looking for alternatives usually fall into a few camps.
Price-conscious users. Fullscript prices include the platform's margin and practitioner commissions. The same products are often cheaper elsewhere. And sometimes a less expensive brand makes an equally effective product. But Fullscript won't tell you that.
Self-directed learners. Not everyone wants to go through a practitioner. Some people want to research supplements themselves, understand the evidence, and make their own decisions. Fullscript's model is built around practitioner guidance. Suppi's model is built around empowering the individual user.
People questioning the recommendations. Once you realize your practitioner earns a commission on what they recommend through Fullscript, you naturally start wondering. Maybe the recommendation is perfectly sound. But the conflict of interest introduces doubt. Independent analysis removes that doubt entirely.
Strip everything else away and this is the core distinction. Fullscript is a commerce platform that facilitates supplement purchases. Suppi is an analysis platform that evaluates supplement quality.
Commerce platforms want you to buy. Analysis platforms want you to understand. You can use both, and many people do. But when the question is "should I take this supplement?" rather than "where should I buy this supplement?", you want the tool whose answer isn't influenced by revenue.
Suppi's revenue comes from app subscriptions. Whether you buy a supplement or don't buy a supplement after scanning it in Suppi has zero impact on Suppi's business. That alignment between the tool's incentive (provide accurate analysis) and the user's interest (get accurate analysis) is the whole point.
Fullscript is a legitimate platform for buying supplements through practitioners. If you have a practitioner you trust and Fullscript is their dispensing tool, keep using it for purchasing.
But don't use it as your analysis tool. Don't assume that because a product is on Fullscript, it's the best option. Don't skip independent evaluation because a practitioner with a commission incentive recommended something.
Use Suppi to verify. Scan the products your practitioner recommends. See whether the doses match clinical research. Check whether cheaper alternatives use the same ingredient forms. Get an independent opinion from a tool that doesn't profit from your purchase.
Independence isn't just a nice-to-have in supplement analysis. It's the whole game.
No products to sell. No commissions. Just evidence-based scoring for 200,000+ supplements. Free.
