When your brain has a long list every day
Names at a work dinner. The reason you walked into the kitchen. The fourth tab you opened and forgot. The last two hours of a long afternoon, when reading the same paragraph twice starts to feel normal.
None of that is a diagnosis. It's what a full life asks of a brain that's also working on sleep, stress, screens and everything else on your plate.
Here's my straight answer as a neuroscientist: the foundations come first. Sleep, movement, real food, time with people you love. No capsule replaces those, and I'd never tell you one does.
What a daily supplement can do is add nutrition you probably aren't eating. Most of us don't have lion's mane, reishi or turkey tail on the dinner menu. ROAR is how I put ten of these mushrooms into one simple routine: two capsules, once a day.
What's actually in the bottle
I'd rather show you the label than describe it. Every amount below comes straight from the Supplement Facts panel on the bottle.
| Ingredient | Amount |
|---|---|
| Lion's Mane Hericium erinaceus, fruit | 266 mg |
| Cordyceps Cordyceps sinensis powder, mycelium | 266 mg |
| Reishi Ganoderma lucidum extract, fruit | 266 mg |
| Shiitake Lentinus edodes extract, fruit | 266 mg |
| Proprietary blend Maitake, Turkey Tail, Chaga, Royal Sun Agaricus, White Button and Black Fungus (all fruit) | in blend |
Serving size: 2 vegetable capsules. Servings per container: 30. Other ingredients: cellulose (vegetable capsule), microcrystalline cellulose, magnesium stearate. The front label lists 1,330 mg per serving.
The lion's mane research, told straight
Lion's mane is the shaggy white mushroom you see on the bottle. It's been part of traditional Chinese and Japanese cooking and wellness practice for a very long time, and it's one of the most studied functional mushrooms in brain research.
Part of the interest comes from the lab. In 1991, Japanese researchers isolated compounds from the lion's mane fruiting body, called hericenones, and reported that they stimulated nerve growth factor production in cell studies. Nerve growth factor is a protein your nervous system uses to maintain neurons. That's a laboratory finding, not proof of what a capsule does in your body, but it's why scientists kept looking.
Then came small human studies. In a 2009 double-blind, placebo-controlled trial in Japan, older adults with mild cognitive complaints took lion's mane fruiting body powder for 16 weeks and scored better on a cognitive function scale than the placebo group. A 2019 study in adults over 50 reported improvements on cognitive tests after 12 weeks. And a 2023 pilot study in young adults found a faster result on one attention task after a single dose, while most other measures didn't change.
What that does and doesn't mean
- !These were small studies using specific lion's mane preparations and amounts. None of them tested ROAR.
- !Results were mixed. Some measures improved; many didn't. Benefits in one study faded after people stopped.
- !So I won't promise you a number, a timeline or a cure. ROAR is a daily nutrition product made to support healthy cognitive function.*
Why I didn't stop at lion's mane
Lion's mane gets the headlines, but it's one mushroom in a big family that people have used for centuries. ROAR adds nine more, so one serving covers a wider range of mushroom nutrition than a single-ingredient capsule.
266 mg of fruit extract. Known in traditional practice as the "mushroom of immortality."
266 mg of mycelium powder. A traditional favorite in Tibetan and Chinese practice.
266 mg of fruit extract. The same mushroom many of us already cook with.
In the blend. A dark, woody mushroom that grows on birch trees in cold climates.
In the blend. Named for its striped, fan-shaped caps.
In the blend. Also called "hen of the woods."
In the blend. Agaricus blazei, originally from Brazil.
In the blend. The everyday button mushroom.
In the blend. Auricularia, common in East Asian cooking.
How to take ROAR
That's the full serving: 2 vegetable capsules.
The label suggests 20 to 30 minutes before a meal, with an 8 oz glass of water, or as directed by your healthcare professional.
A 60-capsule bottle is a 30-day supply. A daily routine is easier to keep than an occasional one.
Is ROAR right for you?
ROAR may be a fit for
- ✓Adults who want a simple daily mushroom routine for brain health support*
- ✓People who'd rather take two capsules than brew powders or teas
- ✓Anyone who wants to read the exact label amounts before buying
Skip ROAR if you are
- ×Anyone under 18, or pregnant or nursing
- ×Anyone with a mushroom allergy (ROAR is made from mushrooms)
- ×Anyone looking for a treatment for a medical condition. Talk to your doctor about that.
If you take medication or have a known medical condition, check with your physician before using ROAR or any dietary supplement. Don't exceed the recommended dose.
What the label tells you
Cellulose capsules, plus two common capsule ingredients. Nothing else is listed.
Printed on the label, with lot number and expiration date on the bottom of each bottle.
Don't use it if the seal is damaged or missing. Store it somewhere cool and dry.
A note from me
I made ROAR for people who want brain nutrition to be simple: one bottle, two capsules, done.
I also want you to buy it with your eyes open. The research on lion's mane is interesting and still early. That's why this page shows you the real label, the real studies and their limits, instead of big promises.
Take it daily, keep the foundations in place, and pay attention to how your days feel. If ROAR isn't for you, my team is a phone call away.

Questions, answered
What is ROAR Lion's Mane?
A dietary supplement with 10 functional mushrooms: lion's mane, cordyceps, reishi and shiitake at 266 mg each, plus a six-mushroom blend. Each serving is 2 vegetable capsules.
How do I take it?
Two capsules once a day. The label suggests 20 to 30 minutes before a meal with an 8 oz glass of water, or as your healthcare professional directs.
How long does a bottle last?
One bottle holds 60 capsules, which is 30 servings: a 30-day supply at the label serving.
Is ROAR the same as ZEN Lion's Mane?
No. ZEN is a separate lion's mane powder sold in a jar. ROAR is a capsule with 10 mushrooms.
Will it work for me?
I can't promise that, and I don't think anyone honestly can. The lion's mane studies are small and used different preparations than ROAR. ROAR is made to support healthy memory, focus and mental clarity as part of a healthy routine.*
Can I take it with my medication?
Ask your doctor or pharmacist first. That goes for any dietary supplement, especially if you have a medical condition.
Who shouldn't take ROAR?
Anyone under 18, pregnant or nursing, or allergic to mushrooms. If you have a known medical condition, check with your physician first.
What's in the capsule shell?
Cellulose. The other listed ingredients are microcrystalline cellulose and magnesium stearate.
