Every batch of The Maca Team maca is independently tested for purity, safety, identity, and quality. Current Certificates of Analysis are made available directly on our product pages so you can see the testing behind the maca you purchase.
Certificate of Analysis (COA) defined: A lab-verified document that confirms identity, purity, safety, potency, and compliance for a specific batch of maca.
Independent laboratory testing is carried out on every batch of maca we sell. This helps us ensure purity, potency, safety, and authentic Peruvian maca with every order.
COAs protect customers by verifying authenticity, purity, and safety with real laboratory data — not marketing claims. They ensure the maca you receive is truly Peruvian, clean, nutrient-rich, and safe for daily use.
You don’t have to simply take our word for it. The testing results for the maca we currently sell are available directly from our product pages.
Maca is a powerful root food with a long history of traditional use in the Peruvian Andes. We honor that heritage and modernize it by making sure that all the products we offer are as healthy and effective as possible.
We test every batch to ensure it is:
If a batch does not meet our testing requirements, we do not receive or sell it.
Each batch is verified by independent third-party laboratories across the key areas below.
| Testing Area | What We Test | Our Requirement |
|---|---|---|
| Identity & Potency | Maca species verification Nutrient profile & natural compounds |
Product identity and specifications must be verified. |
| Microbial Safety | Salmonella E. coli Yeast & mold Aerobic plate counts |
Zero tolerance for Salmonella and E. coli. Other microbial results must meet required specifications. |
| Heavy Metals | Lead Arsenic Cadmium Mercury |
Results must fall well below strict international food-safety guidelines. |
| Pesticides & Residues | Wide-spectrum agricultural chemical screening | Must comply with applicable organic standards. |
| Additional Quality Measures | Moisture content Foreign material Aroma, texture & color |
Must meet our quality specifications before approval. |
Our standard: If a batch does not pass, it is rejected at the processing plant and destroyed. We only receive maca that has passed our testing requirements.
Our quality-control process begins with the roots grown by our farming partners and continues through processing, independent laboratory testing, approval, packaging, and shipment.
| Step | What Happens | Verification |
|---|---|---|
| 1. Grown in Peru | Maca is harvested by our partner farmers in Junín & Pasco, Peru. | High-altitude family co-ops and traceable Peruvian origin. |
| 2. Sorted & Dried | Roots are separated by color, graded, and then sun-dried or dried in large dehydrators for select premium products. | Roots are inspected and prepared for processing. |
| 3. Processed | Roots are made into raw powder, gelatinized powder, or liquid extract. | Each product is processed according to its specific format. |
| 4. Sent to the Lab | Sealed samples are sent for independent laboratory analysis. | Testing is performed through ISO/IEC 17025:2017 accredited laboratories. |
| 5. Safety & Purity Testing | Samples undergo testing for heavy metals, microbes, pesticides, identity, and other quality measures. | A full safety and purity panel must meet specifications. |
| 6. COA Reviewed & Approved | A Certificate of Analysis is issued and the results are reviewed by our processors. | A failing lot is rejected and is not shipped to us. |
| 7. Packaged & Shipped | Only approved lots are packaged and released for shipment. | Fresh, verified, and fully traceable maca reaches our customers. |
We only sell maca that passes every required test without exception.
Below is a sample COA to help you understand the format and the type of information included.
The top section contains important product details such as the batch number, manufacture date, and origin.
The testing section generally contains four important columns:
Each product we send out has a batch number and a “best by” date. You’ll find these on the label or jar.
Looking for your test results? Go to the product page for the maca you purchased and open the tab labeled “Test Results.” That is where we display the current batch testing information.
We keep COAs up to date on product pages, but occasionally there may be overlap between batches. If you open a product page months after ordering and our site is displaying a newer batch, contact us and we’ll email you the COA for your exact batch.
This means you can see test results for the current batch or request the results for the exact batch you purchased — never just a generic reference.
The COA data comes to us in bulk format from our processor. We then upload that information into the product tabs on our site to make the results easier to find and read.
Our processors work exclusively with independent, accredited laboratories that meet international testing standards, specifically ISO/IEC 17025:2017.
Each COA specifies the laboratory that performed the analysis. These labs are certified, accredited, and specialized in botanical and food-safety analysis.
Testing is only one part of our broader quality system. Our standards include:
We use these products ourselves. We give them to our families. You deserve the same confidence and peace of mind.
Yes — every batch is tested immediately after processing by independent accredited labs. Only batches that pass every required marker are prepared for shipping to us.
You’ll find the current COA information directly on the product page for the item you purchased. Look for the tab called “Test Results.” If your product is from an older batch that is no longer displayed, contact us and we’ll email you the COA for your specific batch.
Yes — all maca must fall well below strict global safety limits for lead, arsenic, cadmium, and mercury.
Yes — we screen for a wide panel of agricultural chemicals. Our traditional farmer co-ops grow maca without synthetic pesticides, honoring the way maca has been farmed for generations.
The entire batch is rejected and destroyed. It is never shipped to us or made available to customers. We only receive and sell maca that has passed 100% of required testing.
Yes — all tests are performed by independent accredited laboratories. The lab information appears on the COA.
If you ordered previously and we have since moved to a new lot, simply contact us and we will email you the COA for your specific batch. We keep COAs on file for full traceability.
Yes — all maca products we offer undergo rigorous independent testing, regardless of format or processing type.
Independent laboratory testing is one part of the broader quality system behind every product we offer.
