Forest Power Blend is the widest formula we sell: six mushrooms in one capsule. Width is also the trade-off. Six species means each one gets a sixth of the powder, and there is no capsule count — not even the four-a-day ceiling — at which any single species in this blend reaches the dose its own clinical trial used. That's not a reason to avoid it. It's a reason to know what you bought.
Forest Power Blend combines Cordyceps militaris, Chaga, Reishi, Lion's mane, Trametes Versicolor and Agaricus at 0.5 g of dried fruiting-body powder per capsule. At the recommended two capsules daily that's roughly 165 mg of each species, carrying about 5–7 mg of beta-glucan each — against the 90 mg of beta-glucan in the lion's mane cognition trial. It's built for broad daily coverage in healthy adults, not for replicating a trial result. One caution matters more than the arithmetic: Agaricus has case reports of severe liver injury, so anyone with liver disease or active cancer treatment should clear this formula with a doctor first.
This is a product guide, not a sales page. Below is what's in the jar, what each species is doing there, the per-day numbers worked out honestly, and the two groups of people who should buy something else instead.
What's Actually in Forest Power Blend?
Six dried fruiting-body powders, mixed and encapsulated at 0.5 g per capsule, sold in a 120-capsule jar. No mycelium on grain, no artificial fillers, vegan capsule shell. Here's the line-up and what each one is there to do.
| Species | Role in the formula | Main active class |
|---|---|---|
| Cordyceps militaris | Energy, oxygen use, endurance | Cordycepin, polysaccharides |
| Chaga | Antioxidant load, immune modulation | Melanin, beta-glucans, betulinic acid |
| Reishi | Stress adaptation, sleep, immune balance | Triterpenes, beta-glucans |
| Lion's mane | Cognition, nerve support | Hericenones, erinacines |
| Trametes Versicolor | Immune support, gut flora | PSK, PSP |
| Agaricus | Immune activation, anti-inflammatory | Beta-glucans |
Notice there's no overlap in job description. That's the design intent: one mushroom per major system rather than three mushrooms stacked on the same one. Whether that's the right design depends entirely on what you want from it, which is the next question.
How Much of Each Mushroom Do You Get Per Day?
Divide and see. Two capsules is 1 gram of powder mix across six species, so roughly 165 mg each. Dried mushroom fruiting body carries about 3–4.5% beta-glucan by weight depending on species, which puts each species' contribution at 5–7 mg of beta-glucan per day.
| Daily capsules | Total powder | Per species | Beta-glucan per species |
|---|---|---|---|
| 1 (minimum) | 0.5 g | ~83 mg | ~3 mg |
| 2 (recommended) | 1.0 g | ~165 mg | ~5–7 mg |
| 4 (label maximum) | 2.0 g | ~330 mg | ~10–15 mg |
Now the comparison that matters. The trial that made lion's mane famous — Mori 2009, 30 adults, 16 weeks — used 3 grams of dried powder daily, carrying roughly 90 mg of beta-glucan. Even at the four-capsule ceiling, this blend delivers about a sixth of that from lion's mane. Cordyceps has the same problem against Chen 2010's 3 g of Cs-4, and shiitake-style whole-mushroom doses are further away still.
Six species, six-fold dilution. That's the honest headline. A four-species mix at the same 0.5 g capsule gives each mushroom 50% more; a single-species capsule gives one mushroom everything. Adding the sixth species didn't add a sixth benefit — it moved a slice of an existing one.
Why Six Species Instead of One or Two?
Because the buyer for this product usually has no single target. Someone chasing the Mori cognition result should be buying lion's mane on its own at gram doses, and we say so plainly in our blend versus single species breakdown. Someone who wants one jar covering immunity, energy, stress and focus at once is a different customer with a different problem: adherence.
That problem is real and under-discussed. Four separate jars, four scoops and a schedule is a project most people abandon by week three. Two capsules with breakfast is a habit. A blend at a modest dose taken for twelve weeks beats a perfect single-species protocol abandoned at day nineteen, and the twelve-week timeline is the one that matters in nearly every trial on this page.
Breadth also hedges an evidence problem. Chaga has no published human randomised trial and no established human dose at all. When nobody knows the right number, paying for a bigger number buys certainty that doesn't exist — so 165 mg of chaga in a mix isn't obviously worse than 1,000 mg alone.
How Strong Is the Evidence Behind Each Species?
Uneven, and worth seeing side by side rather than as a marketing list. Two of the six have landmark randomised trials in humans, two have decent human data, one has a specific disease trial, and one has essentially nothing.
| Species | Best human evidence | Trial dose |
|---|---|---|
| Lion's mane | Mori 2009, n=30, 16 wk — cognitive scale improved | 3 g dried |
| Cordyceps militaris | Chen 2010, n=37, 6 wk — VO₂max 1.88 → 2.00 L/min | 3 g Cs-4 |
| Reishi | Tang 2005, n=132, 8 wk — fatigue −28.3% vs −20.1% | 5.4 g |
| Trametes Versicolor | Nakazato 1994, Lancet — 5-year survival 73.0% vs 60.0% | 3 g PSK |
| Agaricus | Therkelsen 2016, n=50, 21 d — symptoms and fatigue improved in ulcerative colitis | Proprietary extract |
| Chaga | No published human RCT | None established |
Read that table as a map of expectations rather than a promise. Lion's mane and Cordyceps have consumer-scale doses this blend cannot reach. Trametes' evidence rests on PSK, a purified protein-bound polysaccharide used in oncology, not on whole powder — a distinction our PSK and PSP explainer goes into. And Reishi's 5.4 g is the largest dose in the field.
The Agaricus Question Nobody Asks
Agaricus is the one ingredient in this formula with a documented signal of serious harm, and it deserves a section rather than a footnote. Mukai and colleagues reported three advanced-cancer patients who developed severe hepatic dysfunction while taking Agaricus blazei extract; two died of fulminant hepatitis. In one case liver function recovered after stopping and deteriorated again when the patient restarted — the closest thing to a causality test these reports can offer.
A 2013 case in Clinical Journal of Gastroenterology described Agaricus-associated liver injury closely resembling autoimmune hepatitis. These are case reports, not incidence data, and all involved concentrated extract preparations in seriously ill people rather than 165 mg of powder in a healthy adult. Both facts matter, and neither cancels the other.
What it means in practice: if you have liver disease, raised liver enzymes, or you are on active cancer treatment, don't take a formula containing Agaricus without your doctor's input. That's not hedging — it's the one place in this product where the downside isn't theoretical. The other species carry milder, better-mapped cautions; our Reishi side effects breakdown covers the antiplatelet one in detail.
Who Is Forest Power Blend For?
Healthy adults with no single target who want consistent daily coverage across immunity, energy, stress and focus, at a cost that makes twelve weeks realistic. At 120 capsules for €69 and two capsules a day, one jar is a 60-day supply at roughly €1.15 a day — less than four single-species jars run to, and one habit instead of four.
It also fits people early in the process. If you've never taken functional mushrooms and don't know which one you respond to, a blend is a reasonable way to find out whether anything in this category does something for you before committing to gram doses of one species. Just don't expect it to identify which one worked.
Seasonal and high-demand periods are the other honest fit. Four capsules for two to four weeks during a heavy training block, a stressful stretch or the winter months is what the upper end of the label range is there for, and it doubles the per-species figures in the table above.
Who Should Choose Something Else?
Anyone with a specific goal that has a published dose behind it. Cognition means lion's mane at 3 g. Endurance means Cordyceps militaris at 3 g. Adjuvant oncology support means PSK, prescribed and supervised, not a wellness capsule. Our lion's mane and Cordyceps dosage guides give the numbers and, more usefully, the timelines to judge them against.
Anyone who needs to know what's working should also skip it. Start six mushrooms at once and any change — good or bad — has six candidate causes. That's not academic with Reishi in the mix, which carries a real antiplatelet interaction relevant if you take anticoagulants or have surgery scheduled.
And two clear exclusions: pregnancy and breastfeeding, where the data simply isn't there for most of these species, and the liver and oncology situations in the Agaricus section above. Under-18s aren't the intended user either.
How Should You Take It?
Two capsules with water in the morning, with or after breakfast, every day. Food helps with the mild digestive upset some people get from whole mushroom powder in the first week, and morning dosing sidesteps the question of whether the Cordyceps component will keep you up — a fair concern given what it does to perceived energy.
Give it four to six weeks before forming a first impression and twelve before a verdict. Nothing in the trial literature behind these species produced its result faster: the shortest study in the table above ran three weeks on an inflammatory bowel endpoint, and the cognition trial took sixteen. Write down where you're starting from — sleep, energy, how often you get ill — because retrospective judgement of a slow, broad effect is close to worthless.
For intensive periods, four capsules daily for two to four weeks, then back to two. Store the jar cool, dry and out of sunlight; whole mushroom powder is more sensitive to heat and humidity than an extract, which is one of the few practical advantages extracts hold.
Can You Stack It With a Single Species?
Yes, and for most people it's the smartest arrangement. Run the blend as a base for general coverage and add one single species at its trial dose for the outcome you actually care about — 3 g of lion's mane for cognition on top of the blend, for instance, rather than hoping the blend's share will do it.
Two rules. Check for species overlap before you add anything, since stacking 3 g of Reishi on a Reishi-containing blend compounds that antiplatelet effect. And add one thing at a time, three to four weeks apart, or you've reintroduced the attribution problem you were trying to solve. Our stacking guide works through the sensible combinations and the pointless ones.
Frequently Asked Questions
How many capsules of Forest Power Blend should I take?
Two daily is the recommended dose, delivering 1 g of powder mix or roughly 165 mg of each of the six species. One capsule is the minimum useful amount and four is the label ceiling, appropriate for two-to-four-week intensive periods rather than indefinite use.
Is a six-mushroom blend better than a four-mushroom one?
Broader, not stronger. At the same 0.5 g capsule weight, six species get roughly 165 mg each where four get 250 mg. You're trading depth per species for coverage, which is the right trade only if you have no single target.
Can I take Forest Power Blend every day, long term?
It's formulated for daily use, and no trial in the underlying literature found tolerance developing over 8 to 16 weeks. The exceptions are situational rather than time-based: liver disease, anticoagulant therapy, pregnancy, breastfeeding, and active cancer treatment all warrant a doctor's input first.
How long before Forest Power Blend does anything?
Four to six weeks for a first impression, twelve for a verdict. The trials behind these species ran from three weeks on an inflammatory marker to sixteen on cognition, and a broad low-dose blend is the slowest version of that, not the fastest.
Does Forest Power Blend contain caffeine or stimulants?
No. The energy component is Cordyceps militaris, which works through ATP production and oxygen utilisation rather than adenosine blockade — so there's no jitter and no crash, but also nothing you'll feel within an hour like a coffee.
