What is Lion's Mane Mushroom?
Lion's mane mushroom, known scientifically as Hericium erinaceus, is an edible medicinal mushroom. It has long, cascading tendrils that resemble a lion's mane, giving it its distinct name. Native to North America, Europe and Asia, lion's mane grows on hardwood trees and logs. It has been used for centuries in traditional Chinese medicine and is now gaining popularity in the Western world for its potential health benefits.
Lion's mane contains bioactive compounds like beta-glucan polysaccharides and erinacines that may offer neuroprotective, anti-inflammatory, antioxidant and immunostimulating effects. Its available in supplement form or as an edible mushroom that can be cooked and consumed.
Potential Health Benefits of Lion's Mane
Ongoing research suggests lion's mane mushroom may provide a number of health benefits:
Supports Cognitive Function
Animal studies show lion's mane may help protect against Alzheimer's disease and dementia by inhibiting the breakdown of nerve growth factor (NGF) in the brain. NGF is important for maintaining neuron health.
Enhances Memory
By increasing NGF levels, lions mane may improve cognitive functions like memory, creativity and analytical thinking. Early research shows it may boost recall and recognition in adults with mild cognitive impairment.
Reduces Depression and Anxiety
Rodent studies reveal lion's mane has anti-depressant and anti-anxiety effects. Improved NGF regulation and reduced inflammation are believed to positively influence mood and emotional disorders.
Relieves Nerve Pain
The erinacines in lions mane may stimulate the release of nerve growth factor, helping relieve neuropathic pain associated with diabetes, chemotherapy and neuralgia.
Supports Digestive Health
Lions mane contains prebiotics that feed healthy gut bacteria, reducing stomach ulcers and inflammation in animal test subjects. It may also minimize GI tissue damage from NSAID use.
Does Lion's Mane Cause Headaches?
There have been rare reports of lion's mane mushroom causing headaches in some users. However, scientific research has not confirmed a direct causal link.
Headaches appear to be an unusual side effect reported by a minority of individuals taking lion's mane. Most experts believe the supplement is generally safe for brain health when taken under professional guidance.
Possible Explanations
There are a few theories that may explain lions mane headaches in sensitive people:
1. Hericenones
These compounds encourage nerve growth factor production. For some, this may result in pressure headaches from overstimulation.
2. Dehydration
Lion's mane has dehydrating effects. Inadequate water intake can trigger headaches in predisposed individuals.
3. Digestive issues
Improperly extracted lion's mane can cause stomach upset, potentially leading to migraines in those prone to them.
4. Contamination
Dirty supplements may contain mycotoxins that provoke headaches in sensitive persons.
Individual Factors
Those more apt to experience lion's mane headaches likely include:
- People with migraine disorder
Any brain stimulant can trigger migraines in susceptible folks.
- Dehydrated individuals
Those who chronically don't drink enough fluids are at higher risk of headaches.
- Contaminant sensitivity
People reactive to molds, metals or chemicals may react to dirty supplements.
- Existing inflammation
Those with brain inflammation may be overstimulated by lions mane.
Safely Taking Lion's Mane Mushroom
You can minimize the risk of adverse effects from lions mane like headaches by:
Choosing high quality supplements
Reputable brands extract lion's mane using clean methods to reduce contamination.
Starting with small doses
Build up your tolerance slowly over several weeks when first using lions mane.
Staying hydrated
Drink plenty of water throughout the day while supplementing with lion's mane.
Avoiding other stimulants
Dont take lions mane with other nootropics or too much caffeine to prevent overstimulation.
Seeking guidance
Consult a doctor or nutritionist to determine optimal, individualized lion's mane dosing.
Who Should Avoid Lion's Mane?
While lion's mane mushroom is generally well tolerated, certain individuals should use caution or avoid it altogether:
Those with stimulant sensitivity
People over-reactive to stimulants like caffeine should be cautious with lions mane initially.
People taking medications that cause dehydration
Diuretics, laxatives, blood pressure meds, lithium and others can predispose you to dehydration.
Individuals prone to migraines
People with migraine disorder may want to avoid lions mane, as brain stimulants can be triggers.
Those using blood thinners
Lions mane may increase bleeding risk when combined with anticoagulant or antiplatelet medications.
Pregnant or breastfeeding women
There is insufficient safety data for lions mane consumption during pregnancy or breastfeeding.
Other Potential Side Effects
Besides headaches, lion's mane mushroom may cause:
Gastrointestinal symptoms
Stomach pain, nausea, diarrhea or constipation due to prebiotic effects.
Itchy skin
Rash or skin irritation, possibly from a histamine response.
Increased anxiety
Nervousness or exacerbation of anxiety disorders from overstimulation.
Excessive sedation
Drowsiness or sleepiness, especially when paired with other sedatives.
Blood thinning
Enhanced anticoagulant activity and inhibited platelet aggregation.
Recommended Dosage
There is no standard lion's mane mushroom dosage at this time. Traditionally, it was eaten as food or boiled into tea.
For modern preparations, most supplements suggest 500-1000mg capsules taken 1-3 times per day. However, always follow label directions or your health practitioner's dosage guidelines.
Start Low
When first using lions mane mushroom, begin with lower doses around 500mg once daily.
Gradually Increase
Slowly work up to higher doses based on your tolerance and desired effects.
Take with Food
Ingest supplements with a meal to minimize potential stomach upset.
Schedule Breaks
Consider taking a week off every 4-8 weeks to prevent overstimulation.
Conclusion
Lion's mane mushroom is an edible fungus used in traditional medicine for its neuroprotective, anti-inflammatory and immunomodulating effects. Research indicates it may enhance cognitive function, memory, mood and digestive health.
Headaches are an uncommon side effect of lion's mane reported by some users. Individual sensitivity, contamination, dehydration and overstimulation may play a role. Those prone to migraines or using blood thinners should exhibit caution.
When taken in moderate doses under medical guidance, lions mane side effects are largely avoidable. However, its best avoided by pregnant women, those taking stimulants or dehydrating medications, and people with bleeding disorders.
