OptiIdentity
High-performance liquid chromatography (HPLC-UV) confirms that each marine active is what the label says it is, at the potency stated.
Made and tested with care
OptiPlax quality standards
OptiPlax is manufactured in the United States in an FDA-registered facility that follows current Good Manufacturing Practices (cGMP), and every production batch is screened by an independent ISO/IEC 17025 accredited laboratory before release. Quality is the process behind the product; the verification page shows the result for the current batch.
What we test on every batch
Potency
Assays verify that astaxanthin and the seaweed actives meet their target amounts per capsule across the batch.
Heavy metals
Because marine ingredients can concentrate trace metals, we screen by ICP-MS and hold each batch to a limit of under 0.6 ppm.
Microbial safety
Total counts and specific organisms are tested to confirm results within USP <2021> limits.
Responsible marine sourcing
The seaweeds in OptiPlax, kelp, wakame, and ecklonia cava, are harvested from managed cold-water fisheries that monitor regrowth and water quality. Astaxanthin is produced from cultivated microalgae rather than synthesized, and chlorella is grown in controlled freshwater systems. Sourcing from clean, traceable origins matters twice over for a marine formula: it protects the antioxidant content we are after, and it keeps contaminants out.
Each incoming raw material arrives with its own documentation, is quarantined, and is identity-tested before it ever enters production. Nothing is blended on trust alone.
cGMP manufacturing
Following cGMP means written procedures for every step, trained staff, controlled environments, calibrated equipment, and full batch records. If a step is not documented, in cGMP terms it did not happen. This discipline is what lets us tie a finished bottle back to its raw materials and its test results, which is the backbone of our verification model.
Independent testing, not just our word
Final-batch testing is performed by Penhallow Reference Labs, LLC, an ISO/IEC 17025 accredited third-party laboratory, so the results do not depend on our own equipment or judgment. The current batch summary, including purity, heavy-metal screening, and the certificate of analysis reference, is published on the verification page.
Quality is the process; verification is the proof. See the live record for batch OPX-2026-C0418 on the verify page, or read the full ingredient list with amounts.
