NATURE CREATED IT. SCIENCE PERFECTED IT.
The Lion's Mane wellness enthusiasts already reach for, grown in liquid-culture bioreactors instead of on grain, and standardized to a compound most Lion's Mane products never measure.
You already know Lion's Mane.
It's one of the most recognizable mushrooms in natural wellness: shaggy and white, with cascading spines, and long associated with focus and mental clarity.
That reputation is well earned. Lion's Mane (Hericium erinaceus) has a long history of use. But what's actually happening beneath that familiar white cap? That's where this gets interesting.
Here's what you probably don't know.
Most Lion's Mane products only use the part of this fungus you can see.
There's another part, easy to miss entirely, that most supplements never touch, and it's exactly where Erinamax is standardized from. Same species. Different source. Here's the path from mushroom to Erinamax.
From mushroom to Erinamax.
From natural source to standardized formula.
Lion's Mane
Recognizable, well known, and the starting point for every claim that follows.
Mycelium
A thread-like network of fungal tissue, not a root system. This is where erinacine A actually comes from.
Erinacine A
The specific compound studied for its role in supporting nerve growth factor (NGF).
Research & standardization
Every batch is measured against a reference standard and independently tested, so the number on the label is the number in the capsule.
Erinamax
Standardized to 5mg of erinacine A per serving. Nature's starting material, understood and verified by science.
Why erinacines matter.
Erinacine A isn't a household name yet, even among people who already take Lion's Mane. Here's the short version, in four terms.
The specific compound Erinamax is standardized to. Found in Lion's Mane mycelium, not the fruiting body.
A thread-like network of fungal tissue, where erinacine A actually comes from.
Nerve growth factor: a protein nerve cells rely on to grow, connect, and stay maintained.
Every serving is verified to contain a specific, consistent amount, not just an estimate.
*This is what NGF does biologically, studied as erinacine A's mechanism. It describes a research pathway, not a guaranteed result of taking Erinamax.
Not all Lion's Mane is the same.
"Lion's Mane" on a label doesn't tell you which part of the mushroom you're actually getting, or which compound it's built around.
Fruiting Body
- The visible, above-ground mushroom
- Associated with hericenones, a different compound class
- What most Lion's Mane supplements on the market are made from
Mycelium
- A thread-like network of fungal tissue beneath the fruiting body
- The specific source of erinacine A
- Standardized to 5mg of erinacine A per serving in Erinamax, verified by third-party testing
What the forest provides.
Lion's Mane mycelium, growing exactly as it has for millennia: a living network, not a formula. Nature is where every claim Erinamax makes actually starts.
What testing confirms.
Erinacine A content, measured by UPLC against a reference standard, batch after batch. Independent testing turns "should contain" into "verified to contain."
What this comparison measures
Values shown are erinacine A content per serving from independent UPLC analysis of retail lion's mane products, as published on the Erinamax landing page at nootropicsdepot.com. Competitor products are shown anonymized.
The science is interesting. Here's why it matters day to day.
Cognition
Erinacine A is studied for its role in supporting focus and overall cognitive function.
Memory
NGF activity is linked to the neuronal processes behind memory.
Mood
Erinacine A's NGF-related activity is studied for its role in supporting a steady, balanced mood.
Nerve Health
NGF is directly involved in the growth, maintenance, and survival of nerve cells.
These statements describe erinacine A's studied role in supporting NGF-related processes. They are not a promise of individual results and are not intended to diagnose, treat, cure, or prevent any disease.

The research behind erinacine A, in three findings.
BDNF/PI3K/Akt/GSK-3β pathway
*The studied biological pathway, not a guaranteed result of taking Erinamax.
In mouse models, erinacine A-enriched Lion's Mane mycelium was linked to changes in NGF-related signaling (the BDNF/PI3K/Akt/GSK-3β pathway), including markers relevant to mood.1
In a double-blind, placebo-controlled trial in older adults, erinacine A-enriched Lion's Mane mycelium was associated with improvements in cognitive and auditory function measures, alongside increases in circulating NGF.2
Human clinical research on erinacine A remains limited. These findings describe studied mechanisms and early clinical signals, not guaranteed outcomes for any individual.
Explore the research
Erinacine A belongs to a class of diterpenoid compounds found exclusively in Lion's Mane mycelium. It's studied for its role in supporting the synthesis of nerve growth factor (NGF), a protein essential to the growth, differentiation, and survival of neurons, via modulation of the BDNF/PI3K/Akt/GSK-3β signaling pathway.1
NGF is a neurotrophic protein responsible for the growth, differentiation, and survival of certain neurons, particularly within the basal forebrain cholinergic system, a region closely tied to memory and cognitive function. Because erinacine A's studied mechanism operates upstream of NGF activity, its research base spans focus, memory, mood, and nerve health, rather than any single narrow outcome.
This section describes mechanistic, preclinical, and early human research on erinacine A. It does not represent confirmed clinical outcomes for every user, and Erinamax is not intended to diagnose, treat, cure, or prevent any disease.

Frequently asked questions.
What makes Erinamax different?
Erinamax is a Lion's Mane mycelium supplement standardized to 5mg of erinacine A per serving, the compound studied for its role in supporting nerve growth factor (NGF), and every batch is independently tested to confirm it.
Why mycelium instead of the fruiting body?
Mycelium is the thread-like network of fungal tissue a mushroom grows from, not a root system, distinct from the fruiting body, which is the visible mushroom above ground. Erinacine A, the compound Erinamax is standardized to, is found specifically in the mycelium.
What is erinacine A?
Erinacine A belongs to a class of diterpenoid compounds unique to Lion's Mane mycelium. It's studied for its role in supporting NGF, the protein tied to nerve cell growth and maintenance.
What does "standardized" mean?
It means every serving is verified to contain a specific, consistent amount of erinacine A (5mg) rather than an unmeasured or variable amount, which many generic Lion's Mane products don't specify.
How is Erinamax tested?
Every batch is independently tested by a third-party lab, including identity testing, UPLC potency analysis for erinacine A content, and heavy metals screening, with results published on a Certificate of Analysis.
How do I take it?
Take two capsules once daily, with or without food, or use as directed by your healthcare provider.
How is this different from traditional Lion's Mane products?
Most Lion's Mane products on the market are made from the fruiting body and are associated with a different compound class (hericenones). Erinamax is built from the mycelium and standardized specifically to erinacine A.
