Quality
What’s on the label is what’s in the bottle.
Made in an FDA-registered facility under current Good Manufacturing Practices. Every batch tested for identity, potency, and purity — including heavy-metal screening. Every claim reviewed against substantiation before it ships.
Four pillars. One standard.
Lab-tested
Every batch is tested by analytical labs for identity, potency, and purity — including ICP-MS heavy-metal screening, microbiological testing, and physicochemical testing. Batch traceability is documented end-to-end.
Source. Manufacturer batch-record + ICP-MS report on file for each production lot.
Quality-certified manufacturing
Manufactured at an FDA-registered facility operating to current Good Manufacturing Practices (cGMP, 21 CFR Part 111). The facility is NSF-GMP registered and ISO 9001:2015 and ISO/IEC 17025:2017 accredited.
Source. Facility registration + cGMP audit records held by the manufacturing partner.
Clean formulations
Every Leandoor product is Non-GMO and Gluten-Free. We disclose the active ingredients on every Supplement Facts panel, in plain English, with the form and dose.

Plain-English science
Every PDP shows the full Supplement Facts panel, the active ingredient form and dose, and uses structure/function language only. No outcome promises, no disease claims, no fear-based marketing.
Source. Internal claims-review policy + the FDA dietary supplement disclaimer site-wide.
