FAQs
You got questions. We got answers.
How does it work?
Lion’s Mane is a functional mushroom long used to support overall wellness, especially brain and nerve health. Modern research suggests that Lion’s Mane may help support:
- Mental clarity and focus
- Healthy brain aging
- Healthy mood and emotional well-being
- Relaxation and healthy sleep patterns
- Nerve and gut health†
Its naturally occurring compounds, such as hericenones and beta-glucans, are believed to play a key role in these effects. Hericenones are unique to the mushroom fruiting body and are being studied for their ability to support the brain’s production of nerve growth factor (NGF), a protein essential to healthy nerve cell function.
At Holleen, we only use 100% organic Lion’s Mane mushrooms (fruiting body only), not mycelium grown on grain. Our extracts are hot water extracted and tested to ensure they contain meaningful levels of active compounds like beta-glucans, which many grain-based products lack. This ensures you're getting a pure, potent product that delivers the benefits Lion’s Mane is known for, without unwanted starches or fillers.
Whether you're looking to support long-term brain health, improve focus, or simply stay sharp, Lion’s Mane can be a valuable addition to your wellness routine.
Can your Lion’s Mane capsules help with cognitive issues?
Lion’s Mane is a functional mushroom known for its potential to support brain health, concentration, and focus. There has also been research in adults with mild memory problems associated with aging that found that those taking Lion’s Mane mushroom powder had improved memory function compared with control participants who did not ingest the mushroom.
Compounds naturally found in Lion’s Mane, such as hericenones and beta-glucans, have been studied for their role in supporting the brain’s natural production of nerve growth factor (NGF), which helps maintain healthy nerve cells.
While Lion’s Mane shows promising potential for cognitive support, it’s important to understand that not all Lion’s Mane supplements are created equal. Many products on the market are made from mycelium fermented grain, which often contain high levels of starch from the growing substrate and very little of the mushroom’s active compounds.
At Holleen, we use 100% organic Lion’s Mane mushrooms (fruiting bodies only),not mycelium and not grain. Our products are hot water extracted and third-party tested to ensure they contain significant levels of key compounds, including:
- Beta-glucans (the active polysaccharides that help support immune and cognitive function)
- Hericenones, unique to the mushroom fruiting body and studied for their impact on neurological health
This difference in quality and composition can have a big impact on whether you’re truly getting the benefits Lion’s Mane is known for. When choosing a supplement for cognitive support, look for one that clearly discloses beta-glucan content and uses only the holleen, not grain or filler.
When and how do I use it?
Take 2 capsules daily in the morning, with a meal and a full glass of water for best results.
Are there any side effects?
No. Our formula is made with natural, clinically studied ingredients and is generally well tolerated by most people.
What if it doesn't work for me?
Most people feel a noticeable improvement within a few days, but we understand that every body is different.
In the rare case it doesn’t work for you, you’re fully covered by our 30-day money-back guarantee.
If you don’t feel a difference, we’ll refund your order. No questions asked.
