Suppie vs SuppCo

SuppCo asks whether you can trust the brand. Suppie asks whether the formula works.

SuppCo is a very good supplement app, now part of Function Health. The two rate different things, and the difference matters when you’re deciding what to take.

SuppCo

Trust and quality signals

Its TrustScore rates products from 1 to 10 on 30-plus quality indicators: manufacturing standards, certifications such as NSF and USP, testing practices, product-quality flags and the credentials of the people behind the brand. It also rates inactive ingredients, runs its own lab-testing certification, and helps you track and buy your stack.

Suppie

Whether the formula works

Suppie grades the formula itself: whether each active’s dose and form matches what was studied, how strong the evidence is for each benefit, safety and interactions, and the risk of every inactive ingredient, ending in a plain verdict. Every part of the report opens up, and you can keep asking Suppie Coach about it.

Same product, two reports

Here’s how each one presents Thorne Magnesium Bisglycinate. Both rate it highly. They tell you different things.

SuppCo product page

  • TrustScore 9.75 out of 10, “Excellent”, with a Tested badge
  • Third-party lab testing and NSF-certified manufacturing
  • Inactive ingredients rated “Safe”
  • Price per serving, and how it ranks on popularity, quality and cost
  • A note that batch-specific certificates of analysis aren’t published
Grade A

Suppie report

Frequently asked questions

They overlap on stack tracking, but they rate different things. SuppCo’s TrustScore is built around brand and product quality signals such as certifications, manufacturing and testing. Suppie grades the formula itself: doses, forms, evidence, safety and every inactive ingredient.
