Certificates of Analysis and testing documentation for our nutritional supplements, and a straight answer on the ones we cannot test this way yet.

What French pharmacy expertise means at Kaia

Cycle System and Urinary Duo are formulated and manufactured in France, rooted in French pharmacy expertise. Our standards bring together clearly disclosed doses, documented manufacturing controls, and batch testing. The manufacturing site follows US dietary supplement current Good Manufacturing Practice requirements under 21 CFR Part 111.

Explore the ingredients and formulas and review the batch documentation below.

What is a Certificate of Analysis?

A COA is the document a laboratory issues for one specific batch. It lists the tests performed, the specification each test had to meet, and the actual result. Ours are issued by the French laboratory that makes our supplements, which runs most analyses in house and sends others to outside labs. If a result falls outside specification, the batch does not ship.

Cramp Patch

Botanical Cramp Patch
US-manufactured topical patch. 8 targeted actives.

Cramp Patch testing: Topical patches suspend active ingredients in an adhesive matrix. There is currently no validated third-party analytical method for precisely quantifying individual botanical actives within this format. Formulation controls ensure each batch targets the labeled ingredient amounts. We are actively monitoring advances in analytical methods and will post results here when validated testing becomes available.

What We Test For

Every supplement batch is screened for

Heavy Metals

Heavy Metals

(Lead, cadmium, arsenic, mercury)
Microbial contaminants

Microbial contaminants

(E. coli, Salmonella, yeast, mold, gram-negative bacteria, total aerobic count)
Active ingredient content

Active ingredient content

(HPLC for vitamins, ICP-MS for magnesium, plate count for the probiotic)
Stability over shelf life

Stability over shelf life

(24-month study underway, results published as they arrive)

If a batch fails any specification, it does not ship.

How We Build a Formula

Research First

Research First

Before any ingredient enters a Kaia Relief formula, the team reviews the clinical literature. Published human trials. Studied doses. Real outcomes. If the evidence is not there, neither is the ingredient.

Source with Standards

Source with Standards

Raw materials are selected for extract quality and standardization. We specify the active compound concentrations (like 95% curcuminoids or 36 mg PACs) because that is what the clinical research measured.

Formulated in France

Formulated in France

Our two supplement systems, Cycle System and Urinary Duo, are formulated and manufactured by a French laboratory in the Loire Valley. Cramp Patch is formulated in France and manufactured in the United States. Each supplement pairs two separately packaged formulas: Day + Night for Cycle System, Botanical + Probiotic for Urinary Duo.

Test Everything

Test Everything

Raw materials tested on arrival. Vitamins verified by HPLC in the finished product, magnesium by ICP-MS, the probiotic by plate count. Heavy metals screened by ICP-MS. Microbial panels run to European Pharmacopoeia methods. A 24-month stability study is running on both supplement systems. If anything falls outside specification, the batch does not ship.

Seal and Protect

Seal and Protect

Every dose comes in an individually sealed protective blister pack. Not for looks. Because loose capsules in a bottle degrade every time the cap comes off. Blister sealing locks out moisture, air, and light from production to the moment you take it.

How to Read a Kaia Relief Label

Every milligram, printed.
When you look at a Kaia Relief label, you see every ingredient and its exact dose. That is not standard. Here is what to look for.
Label Image

No proprietary blends

Some brands group ingredients under one "proprietary blend" weight so you cannot see individual doses. Kaia Relief lists every ingredient individually.

Extract ratios

"10:1 extract" means 10 parts raw plant concentrated into 1 part extract. "95% curcuminoids" means the turmeric extract is 95% active compound. These numbers matter.

Active compound weight

"120 mg cranberry extract delivering 36 mg PACs." We tell you both the total extract and the active compound weight because that is what the clinical research measured.

Day + Night labeling

Each capsule type is labeled separately because they contain different ingredients designed for different times of day.

What Is Coming

We are building toward batch-level transparency: the ability to look up the specific
test results for the exact batch in your box. That system is expected in late 2026.

Match your batch

Compare the batch number on your box with the batch number printed on the Certificate of Analysis. If your batch is not listed, contact the Kaia Relief team with that number so we can help you find the relevant documentation.
