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.

VERIFIED QUALITY

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

Fullscript Tested

Tier 2: Enhanced lab testing

We select products from our inventory and send them to independent labs for blind purity and potency testing. Focusing on popular and higher-risk categories, we’re scaling up to test 250 products per quarter by the end of 2026.

• Brands do not nominate. Fullscript selects.
• Independent product testing with actual consequences.
• Failure results in removal from catalog until all issues are addressed.

PROVIDER TRUSTED

Tier 3: Backed by prescribing data

Fifteen years of prescribing data give you access to see what 125,000+ licensed clinicians are actually recommending — and what their patients keep taking. Trust is built with real-world signals from the field, not paid placements.

• Specialty-level visibility into what your peers prescribe most often – functional medicine, women's health, bariatric care, and other fields.
• Additional insight on the products patients consistently refill.

$8M invested annually

We invest in quality every year, because earning patient trust is pivotal to your practice.

WHAT’S NEXT

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.

WHAT THIS MEANS FOR YOU

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.

Anyone can have a quality story, we live by a standard. The Fullscript Standard.
