A Certificate of Analysis (COA) is a lab report that tells you what was in a specific sample of Lion’s Mane extract, which lab tested it and when. If you are putting an extract into a capsule or powder under your own brand, it is the document you will lean on most.

We publish every lab result we hold for our extract, and each one names the lab, the sample and the date. Below is how we think about testing, and how to read any supplier’s COA with a sceptical eye.

What Is a Certificate of Analysis?

A COA is a laboratory-issued report on a specific sample. A spec sheet says what a product should be. A COA says what a tested sample actually was.

For Lion’s Mane extract, the COA is your evidence. It backs up a label figure with a measured result instead of a promise.

No COA, or a COA you can’t tie to a sample, means you can’t be sure what you are buying.

A useful COA shows:

  • Product and sample identification: What was tested, with a reference or batch number.
  • Dates: When the sample was received and when it was analysed.
  • Test methods: Which analytical method produced each result.
  • Results and units: Measured values, ideally next to the limits they are judged against.
  • The lab: Who issued the report. Ours, for example, include Symbio Laboratories COA S2162602 from May 2026.

Why COAs Matter for White Label and Private Label Brands

Once the extract goes into your product, your brand carries the responsibility. Retailers and regulators look at your label, not your supplier’s.

Good COAs help with:

  • Label accuracy: Any beta-glucan or polysaccharide figure you print needs a result behind it.
  • Formulation: Known composition makes capsule fills and blend ratios predictable.
  • Retail checks: Stockists often ask for supporting documents.
  • Export: Overseas buyers and markets usually want safety and composition records.
  • Fewer surprises: Problems are cheaper to find before launch than after.

For us, publishing the reports is simply part of being a supplier you can check.

Core Potency Testing for Lion’s Mane Extract

Three measures come up again and again when brands assess extract strength.

1. Beta-Glucan Testing

Beta-glucans are polysaccharides found in mushroom cell walls. A measured beta-glucan result is the most common way to describe what an extract contains.

Our most recent figure: Symbio Laboratories measured 32.2 g/100 g beta-glucans in a tested extract blend with 1% BioPerine, in May 2026. A historical sample tested by AEGIC in November 2024 measured 24.5 g/100 g.

We quote both, with their samples and dates, because a single number with no context tells you very little.

2. Total Polysaccharides

Beta-glucans are one group within total polysaccharides. A total polysaccharide figure will usually be higher, because it counts more than beta-glucans.

Results also depend on the test method. If a supplier gives you a polysaccharide percentage, ask which method was used and whether it is total polysaccharides or beta-glucans specifically.

Mixing the two up is one of the easiest ways for a label to overstate what is in the bottle.

3. Extract Ratio

Our extract is 10:1, which our spec sheet records as about 4 kg of fresh Lion’s Mane per 100 g of extract.

A ratio describes how much raw material went in. It does not measure the compounds in the result.

That is why a ratio needs to sit alongside lab results, never instead of them.

Safety Testing Requirements

Safety results matter as much as potency. These are the areas to check on any COA.

1. Heavy Metals

Lion’s Mane mushrooms take up elements from what they grow on, so substrate matters. A good panel covers lead, arsenic, cadmium and mercury as a minimum.

Ours grow on Tasmanian oak hardwood sawdust and Australian soya husk. Nine trace elements were analysed by Symbio (May 2026) and AEGIC (November 2024). Check limits against the market you sell into.

2. Microbial Testing

Powders need microbial checks. Typical panels look at total plate count, yeast and mould, E. coli and Salmonella.

In RMIT University researchers’ April 2025 screening, E. coli and coliforms were not detected (0 CFU/mL).

3. Pesticide Residues

If a supplier makes organic or residue-free claims, ask for the residue testing that supports them.

Growing conditions reduce risk, but only a test confirms it.

Premium retail channels are the most likely to ask.

4. Residual Solvents

Where ethanol or other solvents are used in extraction, it is reasonable to ask how residues are controlled and tested.

Our extraction is hot-water and ethanol dual extraction, and we state that openly on our spec sheet. Ask any supplier to put their method in writing.

Moisture Content and Stability

Moisture affects how long a powder keeps and how it behaves. Too much and you risk clumping and spoilage.

Low moisture helps powder flow, blending and storage. We freeze-dry our fresh mushrooms at −82 °C before extraction, which removes water early in the process.

If moisture matters for your format, ask for it on the COA or spec sheet so you can plan storage and blending.

Third-Party Laboratory Testing vs In-House Testing

In-house checks are useful for day-to-day control. Independent labs give you results that don’t depend on the supplier’s word, and they carry more weight with retailers and export buyers.

We use named external sources: Symbio Laboratories in Sydney, AEGIC, the National Measurement Institute, and RMIT University researchers.

When you assess a supplier, ask which of their results are independent and which are internal. Both have a place. You should know which is which.

How to Read a Lion’s Mane COA

Run through this list every time:

  • Sample match: Does the reference on the COA match the product or sample you are discussing?
  • Date: When was it analysed? An undated report tells you nothing about current stock.
  • Method: Is a recognised method named for each result?
  • Units: Is it g/100 g, %, mg or CFU? Make sure you compare like with like.
  • Limits: Are results shown against the limits that apply to your market?

If something is unclear, ask before you accept the product. A good supplier will answer quickly.

Frequency of Testing and Batch Consistency

Ask every supplier how often they test and what triggers a new test. The answer tells you how much the documents you are shown reflect the stock you will receive.

We keep our reports dated and sample-specific, so you can see which results are current and which are historical.

Consistency matters most for brands with several SKUs or subscription products, where the formula has to hold steady over many orders.

Red Flags in COA Documentation

Be wary if you see any of these:

  • No sample or batch reference: You can’t tie the result to anything.
  • The same COA for every shipment: It may mean nothing new has been tested.
  • No methods listed: The results can’t be checked or compared.
  • Thin heavy metal panel: Lead, arsenic, cadmium and mercury should all be there.
  • No microbial results: A real gap for any powder.
  • Unnamed or unverifiable lab: If you can’t identify who tested it, treat the result cautiously.

A COA should be specific and dated. Generic paperwork is a warning sign.

Testing Standards Supporting Export and Retail Approval

Different markets ask for different paperwork, so plan for it early.

Our Lion’s Mane is grown in Australia, in Thomastown, Victoria. That origin is on our spec sheet, but your destination market sets the rules.

The United States focuses on GMP and documented ingredient testing. European buyers commonly ask for traceability records. Buyers in Asia may request further safety documents.

Tell us where you plan to sell and we’ll share the documents we hold so you can check them against those requirements.

Integrating Lab Testing Into Product Development

Bring the COA into product planning from day one.

Measured beta-glucan results help you work out what a serve contains. Moisture data helps with blending. Safety panels help with retailer and regulatory review.

Our serves are a useful reference point: 1 g for powder and 2 x 300 mg for capsules.

Starting with the documents in hand means fewer reformulations later.

Conclusion

A COA is only as useful as the detail on it. Look for a named lab, a named sample, a date and a method.

Ask every supplier for their reports before you formulate. Ours are on our specifications and testing page, and we’re happy to walk you through them.
