Quality
Lab tested, and the results are yours to read
An FDA-registered facility, GMP certification, an accredited outside lab and a certificate of analysis for every product.
TL;DR
Lunakai supplements are made in the USA in an FDA-registered facility under GMP certification, and an independent accredited lab tests each one for potency, purity and contaminants. The certificates are published per product on the store’s Trust Center. One example: Certified Laboratories, an ISO 17025 accredited lab, found 0.1 mcg of lead per dose in a batch of the PRO Magnesium Complex, against a limit of 6 mcg. No product uses a proprietary blend.
Reading one certificate
PRO Magnesium Complex, batch 26C012
Tested by Certified Laboratories, an A2LA ISO 17025 accredited lab (certificate 3034.01). Received May 19, 2026 and signed May 26, 2026. Four heavy metals, each measured by ICP-MS, per dose:
| Metal | Found | Limit |
|---|---|---|
| Lead | 0.1 mcg | under 6 mcg |
| Arsenic | 0.2 mcg | under 10 mcg |
| Cadmium | 0.1 mcg | under 4.1 mcg |
| Mercury | 0.002 mcg | under 2 mcg |
Every result is a small fraction of its limit: the lead is one sixtieth of it, the mercury one thousandth. Read the PRO Magnesium Complex label beside it.
What does Lunakai test for?
Potency, purity and contaminants, by an independent accredited laboratory. Potency answers whether the amount on the label is in the bottle. Purity and contaminants answer what else is in it: heavy metals, microbes and anything that should not be there.
The results are published per product on the store’s Trust Center, where you search for the supplement you take and read its certificate of analysis, its Supplement Facts and its allergen information.
Where are Lunakai supplements made?
In the USA, in an FDA-registered facility that is routinely inspected, under GMP certification. GMP, Good Manufacturing Practices, is the standard for how a batch is made, checked and recorded so its identity, purity and potency are the same every time. The ingredients come from around the world; the making happens here.
Why no proprietary blends?
Because a blend lets a label print one total for several ingredients, and you cannot tell how much of each you are getting. Every Lunakai label lists each ingredient with its own amount. That is why the product pages here can say 10mg of melatonin, 3,000mcg of B12 or 8,000 FU of nattokinase, and why you can take the exact bottle to your doctor.
It also lets you compare. The heart line states its nattokinase in fibrinolytic units, and the PRO line prints the ratio of its inositol, 40 to 1.
Answers
Testing and quality: your questions
What is a certificate of analysis?
A certificate of analysis, or COA, is an independent lab’s report on a batch: what is in it, how much, and whether it passed for purity and contaminants. Lunakai publishes one for each product on its Trust Center.
Are Lunakai supplements third-party tested?
Yes. Independent accredited labs test each product for potency, purity and contaminants, and Lunakai publishes the results for anyone to read. The certificate on this page is one of them.
What does GMP certified mean?
GMP stands for Good Manufacturing Practices, the standard for how supplements are made, checked and recorded. Lunakai’s products are made under GMP certification in an FDA-registered facility that is routinely inspected.
Does Lunakai use proprietary blends?
No. Every ingredient is listed with its amount. A proprietary blend lets a label give one total for several ingredients, so you cannot tell how much of each you are getting; Lunakai does not use them.
