Lion's Mane
Hericium erinaceus
Small randomised, placebo-controlled human trials have studied Hericium erinaceus extract for cognitive performance and mood, including a 2025 study in healthy younger adults.
The science
Swallowing is the long way round.
A swallowed capsule has to survive stomach acid, then pass through your liver before it reaches your bloodstream. Pharmacologists call that first-pass metabolism. A strip under the tongue skips that step.
Why a strip
Three honest reasons.
Skips the stomach
Under the tongue the tissue is thin and full of blood vessels. Compounds can absorb there without going through digestion first.
About 30 seconds
No water, no chewing, no swallowing. It is done before your coffee cools.
Every dose printed
100mg of four mushroom extracts per strip, all on the label. We haven't tested how much of this exact blend absorbs this way, so we don't put a percentage on it.
How it works
Peel. Dissolve. Done.
- 1
Peel
Tear open one strip. Each is sealed on its own.
- 2
Dissolve
Place it on or under your tongue. About 30 seconds. No water, no chewing.
- 3
Absorb
The blend can absorb through the tissue under your tongue, with no capsule to digest first.
What to expectA functional mushroom blend, not a stimulant: no jolt to wait for, no crash to wait out. We suggest one strip a day for at least 30 days before you judge it. Results vary.
The evidence
Grounded in published research.
We read the published research behind sublingual absorption and behind each mushroom. Here's what is documented, with hedges where the evidence is still early.
A real, documented example
DeMuro et al., J Clin Pharmacol (2000). A study on melatonin, not this product. It shows what first-pass metabolism can do, not Focus Strips' own absorption rate.
Cordyceps
Cordyceps sinensis
Cordyceps sinensis extract has been studied for its effect on exercise endurance capacity, including research into how it acts on skeletal muscle metabolism.
Maitake
Grifola frondosa
Maitake's beta-glucan content has been studied for its effect on immune cell activity, including research on blood cell production in laboratory settings.
Shiitake
Lentinula edodes
A randomized dietary intervention in healthy young adults studied daily shiitake mushroom consumption and measures of immune function.
