Lion’s Mane has become one of the most recognisable functional mushrooms in the world. You’ll now find it in powders, capsules, mushroom coffees and drinks like Earthrise, usually alongside claims about focus, memory and cognitive performance.
The interest isn't entirely new. Lion’s Mane, or Hericium erinaceus, has a long history as an edible mushroom in East Asia and has also been used in traditional practices in China and Japan. What is relatively new is the scientific interest in some of the compounds found inside it and their possible relationship with the brain and nervous system.
The research is promising, but it is also much earlier than a lot of Lion’s Mane marketing would have you believe. We think that's worth being clear about.
So here is what we currently know about Lion’s Mane, where it came from, why scientists are interested in it and why it became such an important part of Earthrise.
What is Lion’s Mane?
Lion’s Mane is an edible mushroom with the scientific name Hericium erinaceus. Unlike a typical mushroom with a smooth cap, it grows in clusters of long white spines that hang down as it matures. Those shaggy white strands give the mushroom its familiar name.
It is found naturally across parts of Asia, Europe and North America, usually growing on hardwood trees.
Lion’s Mane has been eaten as food for generations, particularly in East Asia. In Japan it is commonly known as yamabushitake. It has a mild flavour and an unusual fibrous texture that is sometimes compared with seafood.
Its history is one reason Lion’s Mane first attracted attention, but modern interest has increasingly focused on its chemistry.
Why are scientists interested in Lion’s Mane?
Lion’s Mane contains a range of naturally occurring compounds, including polysaccharides and beta-glucans. Two groups of compounds have generated particular scientific interest: hericenones and erinacines.
Researchers have investigated these compounds because of their potential relationship with nerve growth factor, or NGF. NGF is a protein involved in the growth, maintenance and survival of certain nerve cells.
Much of the research into these mechanisms remains laboratory or animal research, so it is important not to assume that every biological effect observed in a laboratory automatically produces a meaningful effect in humans.
Human research does exist, however, and this is where Lion’s Mane becomes particularly interesting.
What are the potential benefits of Lion’s Mane?
Most of the interest in Lion’s Mane relates to cognitive function, including memory, attention and mental performance.
One frequently cited double-blind, placebo-controlled study followed 30 adults aged between 50 and 80 who had mild cognitive impairment. Participants who consumed Lion’s Mane for 16 weeks showed improved scores on a cognitive function scale compared with the placebo group. Interestingly, scores declined again after supplementation stopped.
A more recent randomised controlled trial looked at healthy adults aged 18 to 45. Researchers found faster performance on one cognitive task following an acute dose of Lion’s Mane and observed a trend towards reduced subjective stress after 28 days. The study was small, however, and its authors concluded that further research was needed.
Other research has produced less impressive results. A four-week study involving healthy college-aged adults found no significant improvement in cognitive function. This inconsistency is important because it tells us that Lion’s Mane is not yet supported by the sort of large, consistent body of human evidence that exists for something like caffeine.
A recent scientific review similarly concluded that Lion’s Mane contains a range of potentially interesting bioactive compounds, while noting that more clinical research is needed to understand their effects in humans.
That is roughly where the science stands today: interesting enough to keep studying, but not settled enough to justify miracle claims.
Does Lion’s Mane help with focus?
Possibly, but this is an area where the marketing has moved faster than the science.
Some small human studies have found improvements in specific measures of cognitive performance, while others have found little or no effect. There is currently not enough evidence to say that Lion’s Mane will reliably improve focus in everyone who takes it.
It also does not behave like caffeine.
Caffeine acts relatively quickly by blocking adenosine receptors in the brain, which reduces the sensation of tiredness. Lion’s Mane is being investigated through completely different biological pathways, and most human studies examining longer-term outcomes have involved repeated consumption over several weeks.
That means someone trying Lion’s Mane should not necessarily expect the obvious sensation produced by a strong coffee.
This distinction is one of the reasons we like it in Earthrise.
Lion’s Mane and coffee aren't the same thing
Lion’s Mane is sometimes described as an alternative to caffeine, but technically that isn't quite right. One is a mushroom and the other is a stimulant. They are different ingredients with different mechanisms.
What Lion’s Mane can do is form part of a different kind of morning drink.
For many people, coffee is not simply about caffeine. It is the ritual of making something warm, sitting down with it and using that moment to begin the day. That is the part of coffee we wanted to preserve when we created Earthrise.
Rather than simply removing caffeine and leaving people with a disappointing decaf, we wanted to rethink what could go into the cup.
That led us towards cacao, spices and functional mushrooms, including Lion’s Mane.
Why Lion’s Mane works particularly well in a drink
There is a very practical problem with many supplements: people buy them and then forget to take them.
A drink is different because it can replace a habit that already exists.
For someone who normally makes coffee every morning, putting Lion’s Mane into a morning drink means there isn't another capsule, tablet or wellness ritual to remember. It becomes part of something they were already going to do.
There is also the matter of flavour. Lion’s Mane has an earthy character that works naturally with cacao and warming spices. Rather than trying to disguise the mushroom inside a tablet, we can make it part of the flavour profile of the drink.
That was a major part of the thinking behind Earthrise.
How we use Lion’s Mane in Earthrise
Lion’s Mane is one of seven functional mushrooms used in Earthrise Original Blend, alongside Chaga, Cordyceps, Maitake, Reishi, Shiitake and Turkey Tail. The base of the drink is organic ceremonial-grade Criollo cacao with a blend of spices including cinnamon, ginger, turmeric, cardamom and cloves.
We then created Stellar Mind for people who wanted a blend more specifically centred around focus.
Stellar Mind contains twice the Lion’s Mane of our Original Blend while keeping the same idea behind Earthrise: a rich morning drink without relying on coffee.
It is important to make one distinction here. Lion’s Mane itself doesn't contain caffeine, but cacao naturally does. A serving of Stellar Mind contains approximately 15 mg of caffeine, significantly less than you would typically find in a cup of coffee.
For us, that makes more sense than trying to recreate the effect of a strong coffee with another stimulant.
How long does Lion’s Mane take to work?
There isn't currently a scientifically established timeframe in which everyone should expect to notice Lion’s Mane.
The human studies have looked at very different time periods. Some researchers have measured cognitive performance shortly after a single dose, while other studies have followed participants for four, eight or sixteen weeks. Results have varied considerably between studies.
That means claims such as “you will feel Lion’s Mane within two weeks” are more confident than the available evidence supports.
It may be more useful to think of Lion’s Mane as part of a regular routine rather than something that should produce an obvious jolt after your first cup.
Does Lion’s Mane contain caffeine?
No. Lion’s Mane mushroom naturally contains no caffeine.
Lion’s Mane products can still contain caffeine if other ingredients are added. Mushroom coffees containing coffee beans, for example, will still contain caffeine.
Earthrise doesn't contain coffee. Our cacao-based Original Blend and Stellar Mind do contain a small amount of naturally occurring caffeine from cacao, with approximately 15 mg per serving. You can see the full Earthrise ingredients and nutrition information here.
This is an important distinction for anyone specifically looking to reduce rather than necessarily eliminate caffeine. If that’s your goal, we’ve also written about how much coffee is too much and how to manage caffeine withdrawal.
Is Lion’s Mane safe?
Lion’s Mane is an edible mushroom and has generally been well tolerated in the small human studies conducted to date. Reported adverse effects have included gastrointestinal discomfort in some participants. Research into long-term supplementation, interactions and particular population groups remains limited.
Anyone with a mushroom allergy should obviously avoid it. If you are pregnant, breastfeeding, taking medication or managing a medical condition, it is sensible to speak with an appropriate healthcare professional before introducing a concentrated supplement.
Lion’s Mane should also not be treated as a replacement for medical care or prescribed medication.
What should you look for in a Lion’s Mane product?
This is an area we think consumers should ask more questions about.
“Contains Lion’s Mane” does not tell you very much on its own. Different products can use different parts of the mushroom, different growing methods, different processing methods and very different quantities.
If you're comparing Lion’s Mane products, look beyond the large claims on the front of the packet. Check the actual ingredients, how much information the company provides about its formulation and whether it clearly distinguishes between Lion’s Mane and other ingredients that may be producing an immediate effect, such as caffeine.
This matters particularly with mushroom coffee. If a product contains a significant amount of ordinary coffee, the immediate energy you feel after drinking it is much more easily explained by caffeine than by Lion’s Mane.
Transparency is more useful than a bigger list of promised benefits.
If you're comparing different options, our guide to coffee alternative drinks looks more broadly at mushroom blends, matcha, chicory and other popular alternatives.
Why we continue to use it
Lion’s Mane sits in an interesting place between traditional food and modern nutritional science.
Humans have been eating it for a very long time. Researchers have identified genuinely interesting compounds within it. Small human trials have produced some promising findings around cognition, while other studies remind us that the evidence is far from conclusive.
We like that.
Earthrise was never supposed to be a magic powder. We wanted to make a better daily drink from interesting whole ingredients and functional mushrooms, without pretending any individual ingredient could transform your health overnight.
Lion’s Mane fits that philosophy particularly well.
It has history behind it, interesting research ahead of it and, when combined with cacao and spices, happens to make a very good addition to a morning drink.
For people who simply want to try Lion’s Mane as part of a broader functional mushroom blend, Original Blend is where we would start.
For people particularly interested in Lion’s Mane and focus, Stellar Mind contains twice the Lion’s Mane of Original Blend and is our most Lion’s Mane-forward morning blend.
Frequently asked questions about Lion’s Mane
Does Lion’s Mane actually work?
There is some promising human research into Lion’s Mane and cognitive function, but the evidence is still limited and results have not been consistent across every study. It is better described as an emerging area of research than a proven cognitive enhancer.
Is Lion’s Mane better than coffee?
They aren't really comparable. Coffee contains caffeine, which is a stimulant with an immediate and well-established effect on alertness. Lion’s Mane does not contain caffeine and is being researched through completely different biological mechanisms.
If you're specifically considering replacing coffee rather than simply adding Lion’s Mane to your diet, we’ve also compared a range of healthy coffee alternatives.
Can you put Lion’s Mane in coffee?
Yes. Lion’s Mane powders and extracts are commonly mixed into coffee, cacao and other hot drinks. Earthrise takes a different approach by combining Lion’s Mane with cacao and other functional mushrooms without adding coffee itself.
Will Lion’s Mane give me energy?
Lion’s Mane is not a stimulant, so it should not be expected to produce the same immediate energy sensation as caffeine. Research has focused more heavily on cognitive function and neurological mechanisms than acute stimulation.
Does Lion’s Mane have caffeine?
Lion’s Mane itself is naturally caffeine-free. Other ingredients in a Lion’s Mane drink may contain caffeine, so it is worth checking the nutritional information.
How long does it take for Lion’s Mane to work?
There is no established universal timeframe. Human studies have ranged from acute testing after a single dose through to repeated supplementation over several months. Effects, when observed, have differed between studies.
What is the best Lion’s Mane drink for focus?
Rather than judging a product purely by the claims on the front of the packet, check how much information the brand provides about its formulation, other active ingredients and caffeine content. Earthrise Stellar Mind contains twice the Lion’s Mane of our Original Blend and approximately 15 mg of naturally occurring caffeine from cacao per serving.
