Mushroom Supplement Regulation in Israel: What the Regulator Checks — and What It Doesn’t
Functional mushroom extracts — Reishi (Ganoderma lucidum, Lingzhi), Lion’s Mane (Hericium erinaceus), Cordyceps and Turkey Tail (Trametes versicolor) — are sold in Israel as dietary supplements, governed by the Public Health (Food) (Dietary Supplements) Regulations and the Protection of Public Health (Food) Law. The short answer: they are fully legal, and the regulator checks safety, manufacturing conditions and labeling — but no clause anywhere measures how much active compound is actually in the bottle. That gap is closed only by an external lab report the producer chooses to commission and publish — and that is exactly what this page teaches you to read.
Key takeaways
- Legal, and not a drug. Under Israeli regulations a dietary supplement is food — “a vitamin, mineral, amino acid, plant or other food approved by the Director for consumption as food, including an extract” — so there is no prescription, no drug registration and no efficacy requirement.
- What is checked: that the product is not a public-health risk, that it is made under Good Manufacturing Practice (GMP), and that the Hebrew label is complete and carries the mandatory warnings.
- What is not checked: how much beta-glucan — or any other active — the bottle contains. There is no regulatory requirement to measure it, and none to publish it.
- Cure claims are prohibited. The regulations let the Director halt marketing of a supplement whose advertising attributes to it “healing or disease-prevention properties.” A brand that promises a cure is out of bounds.
- Research shows why it matters: in the United States, Italy and Thailand — three regulated markets — off-the-shelf mushroom supplements were tested, and in each a large share did not contain what the label promised.
- What closes the gap: an external test report with a lab name, a report number and a measured beta-glucan percentage — not “lab tested” without a number.
Are medicinal mushrooms legal in Israel?
Yes, entirely. Mushroom extracts are sold as dietary supplements, the same category as vitamins and herbal products. No prescription is required and there is no purchase restriction. They are not classified as medicines — and that classification matters, because it also decides what a producer is allowed to promise.
A supplement producer may not claim that the product cures, treats or prevents disease. If a website promises you a cure, that is not just aggressive marketing — it is outside what the rules allow. Everything we write is phrased in the language of what research examines, never in the language of a promise.
The legal frame itself is fairly compact. The Public Health (Food) (Dietary Supplements) Regulations, 5757-1997 define what a supplement is, what may be sold, how it must be manufactured and what must be on the label; the Protection of Public Health (Food) Law, 5776-2015 is the framework law for all food in Israel — manufacturing licenses, import, labeling, and the prohibition on attributing healing properties to food. Both are administered by the National Food Service of the Ministry of Health.
What is the difference between a supplement and a drug — and why does it decide what can be promised?
A drug goes through a registration pathway in which the manufacturer proves efficacy and safety to the regulator before it reaches the shelf. A dietary supplement is food: it must be safe, properly made and correctly labeled — but nobody asks it to prove it does anything. That is why a supplement is allowed to be “safe and ineffective,” and not allowed to promise a cure.
This one distinction explains three things that confuse buyers. First, why you can find products in pharmacies and online that look “approved” and yet carry no documentation of any effect — because approval of a supplement is approval for consumption as food, not approval of efficacy. Second, why serious sites write “research examines” rather than “cures” — because Regulation 9 of the supplement regulations allows the Director to order a halt to marketing when advertising attributes to the product “healing or disease-prevention properties.” Third, why the same warning appears on every bottle: the Third Schedule to the regulations mandates the sentence (in Hebrew) “Pregnant women, nursing women, people taking prescription medication and children — consult a physician,” alongside the manufacturer’s name and address, an ingredient list, directions for use and storage, and a batch number or production date.
What matters to the buyer: all of these requirements are about what is written and how it was made. None of them asks how much. That is not a loophole — it is a deliberate feature of food regulation, which assumes the consumer will demand the proof. How to demand it is below.
What does the regulator check — and what doesn’t it check?
It checks that the product is safe to consume, that it was manufactured in a facility meeting GMP conditions, and that its label is complete and not misleading. It does not check how much active compound is in the bottle, and it does not verify a beta-glucan percentage — because that is not its job.
| What | Checked under the regulation? |
|---|---|
| Product safety and fitness for consumption | Yes |
| Manufacturing conditions and facility standards | Yes |
| Labeling, ingredients and warnings | Yes |
| How much active compound is actually in the bottle | No — not its role |
| Verification of a beta-glucan percentage per extract | No — only an external test the producer initiates |
This is not a criticism of the regulator — it simply isn’t what the system is for. Oversight makes sure that what you buy is safe to consume. It does not make sure it works, nor how much of it is there. Which is how two products can both be perfectly legal and differ fourfold in active content.
Who oversees supplements in Israel — and what is required of a manufacturer versus an importer?
The supervising body is the National Food Service at the Ministry of Health. A local manufacturer needs a manufacturing license and must operate under GMP “to the satisfaction of the Director”; an importer must be registered and use an orderly import track. Both must label according to the regulations — and neither is required to publish an active-compound percentage.
Two different routes lead to the same shelf. A supplement made in Israel — like our extracts — is born in a licensed, GMP-compliant facility; the regulator meets it at the plant level: production conditions, hygiene, documentation, labeling. An imported supplement arrives through an importer, and in recent years that route changed: in 2025 Israel published the Protection of Public Health (Food) (Import of Dietary Supplements by a Proper Importer) Regulations, 5785-2025, which move imports to a “proper importer” track — a registered importer who files an online application and declares compliance, keeps a digital “product file” for seven years, and must notify the Food Service without delay of any safety event. It is part of the “What’s good for Europe is good for Israel” reform that took effect at the start of 2025, bringing oversight of imported food closer to the European standard: less pre-approval by the regulator, more declared responsibility on the importer.
What does this mean for you? That on both routes, responsibility for what is inside stays with whoever sells it. A local producer and a “proper importer” can both market a mushroom extract without anyone ever having measured its beta-glucan. The regulatory track tells you who is responsible; it does not tell you what is in the bottle.
What does oversight actually cover — and what is left to the producer?
A supplement is not a drug, and the regulation around it is built differently. That is not a technicality: it decides exactly which questions remain the consumer’s responsibility.
| Question | Who is responsible |
|---|---|
| That the product is safe to consume | The supplement oversight framework |
| That the label is not misleading and promises no cure | The regulation — which is why wording like “cures” is prohibited |
| That the product is free of contaminants | The producer, through tests it commissions |
| That it contains what the label says, in the amount stated | The producer alone — and only if it chose to test and publish |
| That it is effective for a given purpose | Nobody. A supplement is not required to prove efficacy |
The fourth row is the heart of it. There is no regulatory requirement to publish a measured active-compound percentage, so two products can meet exactly the same regulation and be very far apart in content. It also explains the price gap that otherwise looks inexplicable.
What does the research show about the gap between label and content?
Wherever researchers have taken mushroom supplements from the shelf into a lab, a substantial share of products did not contain what was promised — and this happened in regulated markets, not in their absence. That is why regulation alone is no substitute for a test report.
| Where and when | What was tested | What was found |
|---|---|---|
| United States, 2017 | 19 Reishi (Ganoderma lucidum) supplements bought on the US market | Only 5 of 19 (26.3%) contained the active components consistent with their labels |
| Italy, 2023 | 19 mushroom-based supplements sold in Italy — molecular species identification | Only 6 of 19 matched the labeled species; some “Reishi” products contained a different species of the same genus |
| Thailand, 2026 | 65 Cordyceps products sold online | 54.3% classified as falsified — species substitution or absence of the declared ingredient; 6.2% contained undeclared corticosteroids |
Notice what the three studies share: in every case the products were legal, on sale, and labeled. Regulation did not fail — it never claimed to examine this question. The only measure that caught the gap was chemical measurement: chromatography of triterpenes and polysaccharides in the US, DNA sequencing in Italy, assay of the active ingredient in Thailand. And in Israel? We could not find a comparable published market survey, so we make no claim about the Israeli shelf — we only note that there is no reason to assume it is different until someone measures.
There is a methodological point worth knowing, too: beta-glucan can be measured reliably — a standardized enzymatic method for mushrooms and mycelial products was published in 2016 (McCleary & Draga, J AOAC Int) — so “it can’t be measured” is not an excuse. A brand that publishes no percentage chose not to measure, or not to publish. We go deeper on the difference between beta-glucan and “total polysaccharides” in the dedicated guide.
What should you check yourself before buying?
Four questions — and if the answer to any one of them is “no,” you have no way of knowing what you bought, however legal the product is.
- Is a beta-glucan percentage published? Not “polysaccharides,” not “rich in” — a number.
- Is there a lab name and a report number? Without them there is nothing to verify.
- Is the test per extract, or a one-off? Batches vary, so a single historical test says little.
- Can you see the document itself, not just a summary of it?
With us the answer to all four is yes. The full certificates are open — the signed TÜV Austria test report, with report number and sample code, for each extract separately.
How do you verify a product yourself?
Because regulation does not cover the content question, what remains is self-verification. Four things, in order:
| Step | What to look for | What it reveals |
|---|---|---|
| 1 | Lab name and report number | “Lab tested” without a number cannot be verified |
| 2 | The full certificate, not a summary | A summary lets lines be omitted |
| 3 | That the test is of the extract | A one-off test from 2019 says nothing about your bottle |
| 4 | Beta-glucan, not “total polysaccharides” | Total polysaccharides include starch and carriers |
A certificate can also be verified directly with the lab — which is why the report number and sample code matter more than the logo. We go further on reading a label in Fruiting body or mycelium.
What does an external lab report add on top of regulation?
The one line regulation leaves blank: how much. An external test report (a COA — certificate of analysis) from an independent lab states the beta-glucan percentage measured in the finished extract, the method, the report number and the sample code — and lets anyone verify it with the lab. It is the difference between “compliant” and “measured.”
It helps to understand exactly what is measured, and how. Our document is not a manufacturer’s declaration but a TÜV Austria TEST REPORT — a third party, with a certificate number that can be verified with the lab. The test is run on the finished extract, not on the raw material, so the percentage describes what is in the bottle; and it uses an enzymatic method (the Megazyme mushroom and yeast kit) that distinguishes beta-glucan from alpha-glucan — that is, starch. The line “alpha-glucan: not detected” is chemical proof that there is no grain inside, which is precisely what separates real fruiting body from mycelium grown on rice. How to read such a report line by line — in the COA guide; and why “total polysaccharides” is a number that is easy to inflate — in Beta-glucan vs. polysaccharides.
One more thing regulation will never tell you: what gets measured also depends on what went into the extraction. Our mushrooms go from harvest to extraction without a drying step — as far as we know, one of very few producers anywhere — and we wrote about the difference that makes in Fresh vs. dried mushroom extract. The report measures the outcome; the story is never a substitute for it.
What do we do beyond what is required?
No clause in any regulation requires what follows. We do it because without it you cannot know what you bought:
| What was tested | Lab | Result |
|---|---|---|
| Beta-glucan 1,3/1,6, per extract | TÜV Austria | 23.21%–28.16% · alpha-glucan not detected |
| Lead, arsenic, mercury | VELTIA | Not detected in all four mushrooms |
| Pesticide residues | VELTIA · 610-compound screen | No active ingredient quantified |
| PAH | VELTIA · GC-MS/MS | Below the limit of quantification in all four |
And one point of honesty: test certificates do not fill in the “maximum permitted level” column, so they alone cannot be read as “below the standard.” What can be said is what was measured, by which method, and in which sample — and that is exactly what is published. The full certificates.
The percentages are on a dry-matter basis of the extract, and “tested at TÜV Austria” is the precise wording — the lab measured; it does not “approve” a product. All of our lab tests are open on the lab page, and each report shows which extract was tested. The facility itself operates under GMP conditions with supervision and control — that is the regulatory requirement; the reports are our addition on top of it.
What does regulation not say about a product — and what do we not say?
“Meets Ministry of Health requirements” means the product is safe, properly manufactured and correctly labeled. It does not mean anything was measured in it, that it is effective, or that it is the same as the product next to it. And in the same spirit of honesty — a lab report does not say everything either.
A few words that sound like proof and are not: “approved” — approval for consumption as food, not approval of efficacy or content. “GMP” — an orderly facility, not a measured bottle. “Lab tested” with no name and number — a sentence, not a document. “100% mushroom” — mycelium grown on grain is also mushroom, and the grain gets counted with it. We covered that debate fairly, including the side that defends mycelium, on the Paul Stamets page.
And what we do not claim: the report measures a beta-glucan percentage on a dry basis — we do not convert it to milligrams per milliliter, because that calculation requires assumptions about extraction yield that were not measured. We do not claim “below the standard” on metals, because the certificate does not fill in the limit column. And we do not promise an outcome — not merely because the law forbids it (it does), but because the accumulated science speaks in the language of “studies examine,” and we quote it rather than get ahead of it. More on the rules we set for ourselves — in our FAQ.
How does this compare with the US and the EU — and is Israel different?
Not really. In all three systems a dietary supplement is food, not a drug; in all three, cure claims are prohibited; and in none of them does any regulator measure how much active compound a mushroom extract contains. The differences are in how a product enters the market — not in the content question.
| Israel | United States | European Union | |
|---|---|---|---|
| Framework | Dietary Supplements Regulations (1997) + Food Law (2015) | DSHEA (1994) — supplements are a category of food | Directive 2002/46/EC on food supplements + the health-claims regulation |
| Market entry | Approval for consumption as food, manufacturing license, GMP; imports via the “proper importer” track (2025) | No FDA pre-market approval; the manufacturer is responsible for safety and labeling, cGMP | Notification/registration at member-state level; a new ingredient may need Novel Food authorization |
| Cure claims | Prohibited (Regulation 9; the Law) | Prohibited; structure/function claims require a disclaimer | Only pre-authorized health claims |
| Measuring actives in mushrooms | Not required | Not required | Not required |
That is why the studies in the table above look so similar in the US and Europe: “how much is inside” is not a regulatory question anywhere. The only way to answer it is the same in every country — a lab, a report number, and a document you can open.

The bottom line
Medicinal mushrooms are legal in Israel, the oversight is real — and it does exactly what it was designed to do: safety, proper manufacturing, labeling. The question you actually care about — how much is in the bottle — it leaves to you. Don’t accept “approved” as an answer to it. Ask for a lab name, a report number and a beta-glucan percentage, and you will know what you bought. Regulation says it is safe; only the report says what it is.
Frequently asked questions
Do you need Ministry of Health approval to sell a mushroom extract in Israel?
Dietary supplements are subject to registration and labeling requirements, and manufacturing takes place in facilities that meet the standards. That is different from drug approval, which requires proof of clinical efficacy. A supplement does not go through that pathway — which is also why it may not make medical claims.
If it isn’t a drug, does it even work?
“Supplement” and “no effect” are not the same thing. Some mushrooms have been studied in humans in specific contexts, and in some of those studies no effect was found — and we publish that too. What can honestly be said: there are research directions, there is a recognized mechanism, and there is no promise.
Can a mushroom extract be combined with medication?
Not always. Some drug classes call for caution, among them blood thinners and immunosuppressants. This is not a general recommendation but an individual decision — consult a physician before combining.
Why are some products so cheap if everyone meets the same regulation?
Because regulation examines safety, not potency. Mycelium grown on grain versus fruiting body, the number of extraction stages and the amount of extract in the liquid all affect both cost and outcome — and all of them can be perfectly legal. How to compare price properly
Does “approved by the Ministry of Health” mean the product was lab tested?
No. Approval of a dietary supplement is approval for consumption as food: safety, manufacturing conditions and labeling. It includes no measurement of active-compound content and says nothing about efficacy. A content test is the producer’s initiative — and only when it is published with a lab name and report number can it be verified.
What is the difference between a supplement made in Israel and an imported one?
An Israeli manufacturer needs a manufacturing license and GMP conditions, and the regulator meets it at the plant level. Since 2025 an importer operates on the “proper importer” track — registration, an online declaration and a product file — with more responsibility on the importer and less pre-approval. On neither route is anyone required to measure or publish an active-compound percentage.
Does GMP mean the bottle contains what the label says?
No. Good Manufacturing Practice guarantees an orderly facility — hygiene, documentation, process control. It does not measure how much beta-glucan is in the finished extract. Studies in the US and Italy tested legal, labeled products and found a substantial share did not match the label. Only a measurement in the extract itself answers the question.
How can I check that the lab report I’m shown is genuine?
Look for three things: the lab’s name, the report number and the sample code. With all three you can contact the lab and confirm the document was issued by it. Then check that the report is on the finished extract, that it states beta-glucan (not “total polysaccharides”), and that it is the complete document rather than a summary.
