How Shroom Actives Tests Every Batch: Our COA and Beta-Glucan Standard

Every supplement brand in India claims to be high quality. Labels say “premium,” “pure,” “scientifically formulated.” Packaging looks professional. Claims sound impressive.

But claims are free. Lab tests cost money and require accountability. This post explains exactly how Shroom Actives tests every batch — and why we believe this standard should be the baseline for the entire Indian functional mushroom industry.

The Problem with the Indian Supplement Market

India’s supplement industry is largely self-regulated. FSSAI sets baseline food safety standards, but there is no mandatory requirement for brands to declare active compound concentrations, publish third-party lab results, or verify that what’s on the label matches what’s in the bottle.

This creates a significant quality gap. A brand can legally sell a Lion’s Mane product that contains mostly grain starch — as long as the product technically contains some Lion’s Mane mycelium. A Reishi product can declare “500mg per serving” without specifying whether those 500mg are potent fruiting body extract or low-activity mycelium powder.

In the absence of regulatory enforcement, the only protection consumers have is brands that voluntarily hold themselves to higher standards — and prove it publicly.

What Is a Certificate of Analysis?

A Certificate of Analysis (COA) is a document from an accredited independent laboratory that tests a specific batch of a product and reports what’s actually in it. A genuine COA includes:

• Active compound levels — beta-glucan percentage, specific bioactives (cordycepin, triterpenes, etc.)
• Heavy metal panel — lead, arsenic, mercury, cadmium tested against safe limits
• Microbial safety — E. coli, Salmonella, total aerobic plate count, yeast and mould
• Pesticide residue — for products where agricultural contamination is a concern
• Batch number and date — so you can verify the test matches what you’re buying

The critical word is independent. An internal lab test — done by the brand’s own facility — has an obvious conflict of interest. A third-party COA from an accredited laboratory (NABL-accredited in India, or internationally recognised labs) has no reason to be anything other than accurate.

Why Heavy Metal Testing Matters More Than You Think

Mushrooms are bioaccumulators — they absorb compounds from whatever substrate they’re grown on. This is one of the reasons they can concentrate beneficial bioactives so effectively. It’s also why they can accumulate heavy metals from contaminated growing environments.

Wild-harvested Cordyceps from Tibet, Chaga harvested from birch trees in polluted regions, or mushrooms grown on substrates treated with industrial inputs can carry meaningful heavy metal loads. Lead and arsenic contamination has been documented in multiple international supplement testing surveys.

This is not a theoretical concern. It’s a documented, real quality risk in mushroom supplements — and it’s one that a simple heavy metal panel test completely resolves. If a brand won’t show you their heavy metal test results, that’s a significant red flag.

What Beta-Glucan Testing Actually Tells You

Beta-glucan content is the primary potency marker for functional mushroom supplements. It measures the concentration of the key immunomodulatory polysaccharides that drive most of the documented health effects of medicinal mushrooms.

A quality fruiting body extract typically tests at 20–40% beta-glucans. Mycelium-on-grain products often test below 5% — with the remainder being grain starch.

When a brand declares a specific beta-glucan percentage and backs it with a lab result, they are telling you something real and verifiable about their product’s potency. When a brand is silent on beta-glucan content, they’re usually silent for a reason.

How Shroom Actives Tests Every Batch

Our testing protocol for every production batch:

Step 1 — Raw material verification. Before production begins, incoming mushroom extract is tested for identity (confirming it’s the species claimed), beta-glucan content, and heavy metals. We don’t accept material that doesn’t meet our specifications.

Step 2 — Finished product testing. After production, each batch is submitted to an independent NABL-accredited laboratory for a full panel: beta-glucan content, heavy metals (lead, arsenic, mercury, cadmium), microbial safety (E. coli, Salmonella, total plate count), and moisture content.

Step 3 — QR code linking. Each product carries a QR code printed on the packaging that links directly to the COA for that specific batch. Scan the code on your bottle — you get the actual lab report for what you’re holding. Not a template. Not a generic test from 18 months ago. The specific batch.

Step 4 — Shelf-life monitoring. We conduct stability testing to confirm that active compound levels remain within specification through the product’s shelf life.

Why We Do This When We Don’t Have To

Honestly — it’s more expensive and more work. We don’t have to do batch-level COAs. Most Indian supplement brands don’t.

We do it because the functional mushroom category in India is at an early, critical stage. If consumers can’t trust what’s in the bottle, the entire category gets tainted. One brand selling low-quality mycelium-on-grain products and calling it Lion’s Mane makes every Lion’s Mane brand less credible.

We also do it because Dann — our co-founder — came into this industry through the cultivation side. He’s seen what the raw material supply chain looks like at ground level. He knows what corners are easy to cut and what the consequences are. The testing protocol we have isn’t a marketing exercise — it’s what someone would build if they actually understood the supply chain risks.

How to Verify Any Brand’s COA

When evaluating any mushroom supplement brand, ask these questions:

1. Is there a COA available for this specific batch (not just a generic product test)?
2. Who conducted the test — is it a named, accredited independent laboratory?
3. Does the COA include heavy metal testing, not just active compound levels?
4. Does the beta-glucan percentage match the label claim?
5. Is the test date recent (within the last 12 months for the current batch)?

If you can’t get clear answers to all five questions, that’s information too.

Scan the QR code on any Shroom Actives product and you’ll find our batch COA — every test result, every batch, publicly accessible. That’s the standard we think every brand should meet.
