Third-Party Tested. Every Single Batch.
We don't ask you to take our word for it. Every batch of Crocea Hawaiian Astaxanthin is sent to an independent, ISO/IEC 17025-accredited laboratory before it ever reaches you.
Why we test every batch
Independent research has found that a large share of the astaxanthin sold today is synthetic (made from petrochemicals) and many products are under-dosed well below the amount used in clinical research. The only way to know what's actually in a softgel is to test it.
So every Crocea batch is tested by an independent lab against the standards below. If a batch doesn't meet spec, it doesn't ship.
What every batch is tested for
| Test | The standard we hold every batch to |
|---|---|
| Astaxanthin potency | ≥ 12 mg per softgel — the clinically studied dose (not an under-dosed 4–6 mg) |
| Identity / source | Natural Haematococcus pluvialis — Hawaiian microalgae, never synthetic |
| Heavy metals | Lead, arsenic, cadmium, mercury — below USP <2232> limits |
| Microbiology | Total plate count, yeast/mold, E. coli, Salmonella — within USP limits |
| Oxidation | Peroxide value within spec (oil freshness) |
| Carrier & form | Oil-based softgel for absorption (astaxanthin is fat-soluble) |
These are the batch-release standards every production lot is tested against by an independent, accredited laboratory.
Certificates of Analysis
Our current batches are completing third-party testing. The signed certificates will be published on this page as soon as they're available.

Common questions
What is a Certificate of Analysis (COA)?
A COA is a document from an independent laboratory that reports what testing was done on a product and the results — for example, confirming the actual astaxanthin content and that heavy metals are below safety limits.
Why does the dose (12 mg) matter?
The human studies on astaxanthin and eye comfort generally used around 12 mg per day. Many products contain only 4–6 mg, below the amount used in that research. We formulate and verify at 12 mg.
How do I know it isn't synthetic?
Our identity testing confirms the astaxanthin is natural Haematococcus pluvialis from Hawaiian microalgae — not the synthetic, petrochemical-derived form that makes up most of the market.
Is it safe?
Every batch is screened for heavy metals and microbial contamination against USP limits, and manufactured in a cGMP facility in the USA. As always, talk to your doctor before starting any supplement.
