11 best Lion's Mane supplements to improve focus & productivity
Featured in this article
The best Lion's Mane supplements have been on our radar — and our shelves — for quite some time now. Because it seems that everyone, including our friends, family members and TikTok nutritionists are recommending the dietary supplements.
But why the sudden boom? Quite simply, Lion's Mane benefits include better focus, mental clarity and a reduction in stress levels — yeah, this is a wonder fungi. But are Lion's Mane supplements (otherwise known as Hericium Erinaceus) a worthy addition to your wellness routine or simply a passing trend?
According to Bettervits’ Accredited Nutritionist and Head of Product, Harriet Hunter, it's the former rather than the latter: “Lion’s mane is a mushroom native to select parts of Asia, Europe, and North America that has long been used in Traditional Chinese Medicine for its renowned neuroprotective and antioxidant properties. But in more recent years, it has gained popularity worldwide as a dietary supplement extract."
Hunter adds that studies and personal anecdotes alike remark on its ability to promote feelings of calm and focus in the brain. “Scientific research also shows exciting and promising applications for those seeking mental health support and long-term cognitive health benefits," she adds.
Even better news: thanks to the huge increase in interest in Lion's Mane, there's a whole host of supplements on the market to choose from. We're talking easy-to-swallow Lion's Mane capsules, powders, liquids, and even those drinkable as matcha-style lattes — most of which we (a team of Glamour editors) put to the test for a minimum of four weeks.
So, stay tuned for answers to all your Lion's Mane FAQs, as well as a list of the very best mushrooms to boost your mental and physical wellbeing.
How we test the best Lion's Mane supplements:
The Glamour team are a hard-working bunch, spending their evenings and weekends moonlighting as beauty and wellness testers — AKA the best sleep supplements, electrolytes, green powders — to uncover which move them closer to their fitness, focus and health goals.
Each willing volunteer was asked to try one Lion's Mane supplement for a minimum of four weeks. At the end of their trial period, they were asked to rate it against the following criteria:
- Ease of use — Were the capsules easy to swallow? Did the powder mix well with water?
- Efficacy — How long into the four weeks did they notice a difference, if any?
- Taste — On a scale of one to five, how pleasurable was the taste?
- Value for money — Would they be happy to commit to the weekly, monthly or bi-monthly spend?
Unsurprisingly, only our fan-favourites made it onto our list below.

What is Lion's Mane, and what are the benefits?
“Lion’s Mane is a type of medicinal mushroom,” details women’s health nutritionist Stephanie Smith. “These are fungi with purported pharmaceutical benefits.” Another word for this type of mushroom is ‘functional,’ which dietitian nutritionist Lena Bakovic says has taken off in recent years.
“Their popularity has grown due in large part to the mushrooms’ purported adaptogenic properties,” she says. “Adaptogens, which have been a constituent of Eastern Medicine for many years, are thought to help counteract the effects of stress on our bodies.”
Recent studies suggest that Lion's Mane may help alleviate stress and improve focus or speed when completing tasks, but further research is needed on a larger scale. “The research on lion's mane is promising but still developing,” adds Doctify-rated nutritionist Raquel Britzke. “Some studies suggest benefits for memory and brain function, but we need more human trials. Some research also suggests gut microbiome benefits."

Lion's Mane FAQs, answered:
What is the best way to take Lion's Mane?
“To get the most out of your supplement, look for a fine powder form of lion’s mane,” says Bettervits’ Accredited Nutritionist and Head of Product, Harriet Hunter. “The particles will increase bioavailability within the body. Additionally, taking the supplement with or alongside a meal rich in healthy fats may help improve absorption”.
Wondering what time of day is best? Hunter adds that there is no single best time to take Lion’s Mane. “However, it is often recommended as part of a morning routine to help support its benefits throughout the day,” she adds.
Are there any side effects of taking Lion’s Mane supplements?
Lion's Mane supplements are considered to be ‘well-tolerated’ by most, meaning side effects are rare. However, Bakovic says there are a couple of key signs to watch for: "The side effects that have been reported are related to digestive upset, potentially allergic reactions, and skin rashes.”
“For most people, lion's mane is considered safe when consumed in food amounts or taken as a supplement from reputable sources," adds Doctify-rated nutritionist Raquel Britzke. “However, some individuals may experience mild digestive discomfort or allergic reactions. It may also interact with blood thinners or medications for diabetes due to its potential effects on blood clotting and glucose regulation.”
Who should and shouldn’t take Lion’s Mane?
“As with all supplements, there is not always a need to take them," stresses Smith. "However, if people are looking for help with focus, concentration, nervous system support or would like to supplement specifically for brain and cognitive health, then Lion’s Mane could be something of interest.”
In terms of who should avoid it, Bakovic notes that, “due to the limited amount of research supporting the benefits of these mushrooms at this time, and especially during pregnancy, it is advisable that pregnant women should avoid taking Lion's Mane mushrooms or supplements.”
“But before taking any supplement, it is recommended to discuss it first and foremost with a healthcare provider/physician to ensure that there are no potential dangers or drug/nutrient interactions.”
