What This Product Is
Transparent Labs Mushroom Stack is a three-species capsule blend built around organic Lion’s Mane, organic Reishi, and organic Cordyceps sinensis. The brand markets it for cognitive support, endurance and recovery, and immune function. We have not purchased, taken, or tested this product. Everything below comes from the official product page, the published Certificate of Analysis, and independent research on these three mushroom species.
Label Breakdown: What’s Actually Disclosed
Here is every dose disclosed on the current official label, listed exactly as Transparent Labs presents it:
- Organic Lion’s Mane (Hericium erinaceus): 1,000 mg per serving — 50% of the total blend
- Organic CordycepsPrime™ (Cordyceps sinensis): 500 mg per serving — 25% of the total blend
- Organic Reishi (Ganoderma lucidum): 500 mg per serving — 25% of the total blend
- Total blend per serving (3 capsules): 2,000 mg
A few things worth flagging for label readers. The official product page does not specify whether these are fruiting-body-only extracts, mycelium-on-grain, or full-spectrum powders, and it does not list a beta-glucan percentage or extraction ratio for any of the three ingredients. That matters because extract form changes what you’re actually paying for — a whole-mushroom powder and a standardized 10:1 extract are not nutritionally equivalent even at the same milligram weight. Until Transparent Labs discloses extraction method and standardization on the label itself, treat that detail as unconfirmed. [VERIFY BEFORE PUBLISHING]
Dose Math: Is 2,000 mg a Lot?
Total milligrams per serving is a starting point, not the whole story. As we lay out in our dose math guide, what matters more than the headline number is (1) how the total splits across species, (2) whether each individual dose lines up with amounts used in published research, and (3) whether the extract type is disclosed.
On the split: this formula weights Lion’s Mane at double the other two species, which is at least transparent — many “proprietary blend” products don’t disclose individual amounts at all. The Lion’s Mane dose (1,000 mg) and Reishi dose (500 mg) fall within ranges commonly used in small human studies on cognitive and immune outcomes, though study designs, populations, and extract types vary widely enough that no single product’s dose can be said to replicate any specific trial’s results.
On cost per serving: at the official listed price of $24.99 for 30 servings, that works out to roughly $0.83 per serving. [VERIFY BEFORE PUBLISHING — confirm current price at checkout, as third-party retailers list this product anywhere from about $30 to $60]
What the Label Proves, What Research Suggests, What Remains Unknown
What the label proves: The company discloses individual milligram amounts per mushroom rather than hiding behind a blend total, the product carries Informed Choice certification, and a Certificate of Analysis is published for purity testing.
What research suggests: Cordyceps compounds may support energy metabolism and exercise tolerance in some study populations. Reishi triterpenes and polysaccharides have been studied for potential immune-modulating and antioxidant effects. Lion’s Mane has been researched for potential nerve growth factor stimulation and cognitive support. None of this research was conducted on this specific product, and results from isolated extracts in a lab or small trial don’t automatically transfer to a commercial capsule blend.
What remains unknown: Extraction method and standardization aren’t disclosed on the current label. There’s no independent third-party clinical trial on this exact formula. Individual response to adaptogenic mushrooms varies, and the company’s own FAQ suggests full effects may take three to four weeks of consistent use to evaluate — a timeline that itself hasn’t been independently verified.
Who Might Want to Avoid It
People who are pregnant or breastfeeding, anyone on immunosuppressant medication, anyone with a known mushroom or fungal allergy, and anyone scheduled for surgery in the near future (some mushroom compounds may affect blood clotting or blood sugar) should talk to a doctor before starting a product like this. People taking medications for diabetes or blood pressure should also check for interactions, since some mushroom compounds studied in Cordyceps and Reishi may influence blood sugar or blood pressure. This is not a complete list, and it is not a substitute for a conversation with a pharmacist or physician who knows your full medication list.
Reading the Certificate of Analysis
Transparent Labs publishes a COA for this product rather than only saying testing happens. If you’re evaluating whether that COA actually tells you what you need to know — batch-specific results versus a one-time test, what contaminants were screened, and how current the document is — our COA reading guide walks through what to check before you treat a published PDF as proof of quality.
How It Compares to a Gummy Format
Capsules and gummies solve different problems. Capsules like this one let a brand pack a higher total milligram dose (2,000 mg across three species here) into a small serving, but they ask you to remember a daily pill and don’t disclose flavor or sugar content, since there isn’t any. If you’re weighing a capsule stack against a gummy format, we’ve broken down what a gummy version of a mushroom blend discloses on its own label in our Pilly Mushroom Gummies review, including its own dose-per-serving breakdown for a same-format comparison.
If you’d rather see a gummy-format option directly, Pilly Labs’ Mushroom Gummies lists its own per-serving mushroom amounts on the product page — worth checking side by side using the same dose-math approach above.
Bottom Line
Transparent Labs Mushroom Stack discloses individual doses for all three mushroom species, publishes a COA, and carries third-party Informed Choice certification — all things a label-first reader should want to see. What it doesn’t yet disclose is extraction method or standardization, which matters for judging whether 2,000 mg of “mushroom” is doing what a research-backed extract would do. We haven’t tried this product and can’t tell you how it feels to take. What we can tell you is what the label supports and where the gaps are.
Frequently Asked Questions
Is Transparent Labs Mushroom Stack third-party tested?
Yes. The company publishes a Certificate of Analysis for this product and states the formula is Informed Choice certified, which involves third-party screening.
How many capsules do I take per day?
The official label directs 3 capsules daily, preferably with a meal or as directed by a healthcare professional. This is label information, not a recommendation from us.
Does this product contain fruiting body or mycelium extract?
The current official product page does not specify this detail for any of the three mushroom ingredients. Reach out to Transparent Labs directly or check the physical label before purchasing if extraction form matters to your decision. [VERIFY BEFORE PUBLISHING]
How long before I’d notice anything?
The brand’s own FAQ states initial cognitive and energy effects may appear within a few days, with fuller immune-related effects taking several weeks of consistent use to evaluate. This is the company’s stated timeline, not an independently confirmed one, and individual experience may vary or may not occur at all.
Is this product safe to combine with medication?
Some compounds in Cordyceps and Reishi have been studied for effects on blood sugar, blood pressure, and blood clotting. Anyone on related medications, or with an upcoming surgery, should ask a pharmacist or doctor before starting this or any similar mushroom supplement.
