At Triterra Farm, Transparency Is the Product

The functional-mushroom supplement market is full of promises: “premium,” “potent,” “natural,” “traditional.” What’s almost always missing is the number. How much β-glucan is actually in it? Were heavy metals tested? What exactly is inside the capsule? These questions are simple — but the answers cost money, demand quality cultivation, and expose what many prefer to keep vague. We chose the opposite path, and on this page we’ll explain exactly why.

What’s easy to hide in the functional-mushroom industry

This isn’t a conspiracy theory — it’s a structure of incentives. Vagueness is cheaper than transparency, which is why it’s the market’s default. Here’s what it covers up:

1. Mycelium on grain instead of fruiting body

The cheap global-market standard is mycelium-on-grain — growing mycelium on rice or oats and grinding it all together. The result: a product that is mostly starch from the grain, with β-glucan content most often measured below 7%. A quality fruiting body reaches 25–40%. The difference is enormous — but without testing, there’s no way to know what you bought.

2. The label trick: “Polysaccharides 30%”

A “polysaccharides” claim sounds impressive — but starch is a polysaccharide too. A brand that writes “Polysaccharides: 30%” could simply be measuring the starch from the grain. The number that really matters is β-glucans as a precise percentage — and that’s exactly the number most manufacturers won’t state.

3. Powder instead of extract

A powder capsule = dried, ground mushroom, with no extraction. The cell wall (chitin) resists digestion, and most of the active compounds leave the body without being absorbed. Cheap to produce, sounds similar on the shelf — but completely different from what the body actually absorbs.

4. No COA, no heavy metals, no source

Mushrooms absorb from the substrate whatever is in it — including heavy metals and contaminants. Cheap imported products have been found with lead, arsenic and cadmium. A certificate of analysis (COA) showing heavy metals, pesticide residues and mold is the consumer’s most basic protection — which is precisely why its absence is so common. If they don’t show you, it’s worth asking why.

What we publish: COA, β-glucan and cultivation source

For every point of vagueness in the market, we have an open answer. Not because we’re “nice” — but because a product built on measurable chemistry has to prove it.

Beyond that, the only external backing we do rely on is independent standards: β-glucan testing at the TÜV Austria lab, Ministry of Health approval, and Mehadrin kosher certification. These aren’t our own declarations — they’re the stamps of external bodies.

The proof you can’t fake: the gap between “polysaccharides” and β-glucan

This may be the most important point on the whole page, and it’s simpler than it seems. The total “polysaccharides” a brand declares is made up of two parts:

Total polysaccharides = alpha-glucan (mostly starch) + β-glucan (the active compound)

The β-glucan is what the body recognizes and responds to — the compound you bought it for. The alpha-glucan is mostly starch, and in mycelium-on-grain products it comes straight from the rice or oats the mycelium grew on. In other words: the gap between “total polysaccharides” and “β-glucan” is the amount of starch.

And here’s the proof you can’t fake: when the two numbers on the certificate of analysis are nearly identical — that’s mathematical proof there’s almost no starch. What was measured is pure mushroom, not filler. A large gap = lots of grain starch. A near-zero gap = a real fruiting body. And in our case it isn’t “nearly” — on the TÜV Austria COA, the presence of glucans (starch) is marked “not detected”: below the lab’s detection threshold.

The table: where Triterra sits in the market

To be fair — there are genuine premium brands in the market, both abroad and here in Israel. Some are even peers we share knowledge and professional respect with — because anyone who raises the bar benefits the whole market, both us and consumers alike. We’re not the only ones who care, and that’s exactly fine. Our specific difference comes down to two things: local cultivation in the Galilee (full control over the substrate and growing conditions), and an open COA for the specific batch you bought — not a sample or periodic test. Here’s the full picture:

Notice what happens in the table: against the cheap standard the difference is a chasm, and against premium the difference narrows to two rows — but that very narrowing is the honesty. We don’t pretend to be “the only good ones”; we apply the premium standard in Israel, with fresh local cultivation and transparency down to the single batch.

5 questions that expose any functional-mushroom brand (including us)

You don’t have to be a chemist to spot a quality product. These five questions expose any brand in 30 seconds. Ask them of everyone you’re considering — and ask us first. For each one, we have an open, verified answer.

1. Which part of the mushroom is the product made from?

   Fruiting body, mycelium or spores — each with a different profile. A quality brand states it explicitly. Us: 100% fruiting body.

2. What’s the precise β-glucan percentage?

   Not “polysaccharides” (which includes starch) — but β-glucan as a number. Us: 23–28% depending on the species, verified for every batch.

3. Is there a COA for the specific batch I bought?

   Not a sample or periodic test — for your batch. Us: an open COA for every batch.

4. Were heavy metals, mold and contaminants tested?

   Mushrooms absorb from the substrate. A proper COA includes these tests. Us: tested and published.

5. What’s the extraction method and ratio?

   Water only = partial; triple extraction = full spectrum. Us: triple extraction 1:3.

The principle: don’t ask for trust. Invite verification.

This is the heart of our approach. Most marketing asks you to trust — a brand, a story, a pretty picture. We ask for the opposite: don’t take our word for it. Take the batch number on the bottle, go to the lab-results page, and see for yourself what’s inside. A product that invites scrutiny is a product with nothing to hide.

Why this matters to you in particular

Beyond the principle, this has a practical meaning. When you pay for a functional-mushroom extract, you’re paying for the active compounds — the β-glucans and triterpenes. If they’re not there, you paid for starch and expensive powder. Our transparency is your way to know exactly what you paid for. Not a promise — a receipt.

And if you’re a practitioner or professional, it’s doubly critical: you can’t recommend a product to a client that can’t be verified. That’s why we built a professional space for practitioners with the full raw data.
