Trust isn’t given, it’s earned
Every supplement you recommend is held to the same rigorous standard — brands verified before being listed, select products subject to enhanced testing with real consequences, and continuous monitoring to ensure trust.
If it’s on our shelf, it’s earned its place.
We hold the standard, so you don't have to
Most quality claims rest on a single checklist at sign-up. Our three-tiered system is always-on, and each layer helping you make more confident product decisions.
The Fullscript Standard
The promise that holds quality assurance together. Every product must live up to these standards to be listed — earning a badge that can’t be bought.
Tier 1: Brand vetting standards
Before a product reaches our catalog, your clinic, or your patients — its brand and contract manufacturer must verify third-party cGMP certification. This is a standard they must prove annually, not just at onboarding.
Mandatory third-party cGMP certification
Verifying product labeling and claims
Inspecting new certificates of analysis and stability data
Stored in Fullscript's NSF cGMP-certified, FDA-registered facilities
$8M invested annually
We invest in quality every year, because earning patient trust is pivotal to your practice.
Making the standard even stronger — Fullscript Outcomes
Soon The Fullscript Standard will take a leap from clean and widely prescribed — to proven impact. Combining lab results and real-world prescribing data to give providers a clear signal on what products are driving better patient outcomes.
In development
Testing without action is all talk
Last year, we conducted blind potency and purity testing on 365 products. Three failed to meet our standards. Here’s how we took action.
A top-selling B12 failed potency in independent testing
A popular product from a major brand.
- What testing found: Failed potency testing in Fullscript's quarterly blind program.
- What Fullscript did: Immediately delisted. Direct coordination with the brand drove a full reformulation that subsequently passed purity and potency testing.
- Outcome: Returned to catalog after reformulation
Clinical implication: Clinical efficacy is dose-dependent. If a product fails potency, the patient is not receiving the prescribed therapeutic dose.
An under-potent gummy was permanently removed
A gummy from a major brand.
- What testing found: Failed potency testing in the quarterly blind program. The brand was relying on input-material review rather than finished-product testing.
- What Fullscript did: Retesting of a retained sample by the manufacturer confirmed Fullscript's result. Product was removed from catalog and returned to the manufacturer.
- Outcome: Permanently removed
Clinical implication: A product that fails potency is one the patient is not receiving the prescribed dose of — regardless of what the label or the COA at onboarding said.
Products you can actually believe in
Getting in the Fullscript catalog doesn’t guarantee staying in. Our ongoing vetting and continuous third-party testing is designed to help earn the trust of providers and patients. Outcomes are shared. Consequences are real. Confidence built at every step.
