Recent studies have shown that consumption of Lion's Mane mushrooms (Hericium erinaceus) could reduce certain symptoms related to attention deficit hyperactivity disorder (ADHD), notably challenges with concentration and learning. Caution is advised, however, as support for these claims is currently limited.

Lion's Mane mushrooms are a type of edible fungus mainly found in East Asia. For centuries, traditional Chinese medicine has used Lion's Mane to treat a range of conditions, including depression and anxiety.

Unlike some ‘miracle’ supplements on the market Lion’s Mane is not a new phenomenon; health food stores have sold it as a dietary supplement for several years. It’s the application of Lion’s Mane that makes these new studies particularly interesting.

The studies suggest that Lion's Mane may have nootropic effects, potentially improving cognitive functions like learning, thinking and memory. Consequently, it could be helpful in managing certain symptoms of ADHD. To date, research on the health benefits of Lion's Mane in humans is limited.

Most studies focus on its impact on mental health and brain function, especially in individuals with Alzheimer's Disease and other neurodegenerative disorders. Researchers believe that the mushroom may have neuroprotective and neuroregenerative properties.

Research has yet to accurately prove how treatment with Lion’s Mane impacts the symptoms of ADHD. However, some small clinical trials suggest lion’s mane extract may improve some symptoms:

A study from 2023 indicated that lion's mane might help lower stress and improve cognitive function, including learning ability and the speed of cognitive processing.

A 2022 narrative review examined the potential therapeutic effects of lion's mane in

individuals with Alzheimer's disease. It referenced three clinical trials that indicated lion's mane could positively impact cognitive abilities and mental well-being, which may also relate to ADHD symptoms.

A 2021 animal study investigated the effects of mushrooms on neurodegenerative diseases and found that lion's mane might improve certain cognitive functions, such as memory.

Nootropics, often referred to as ‘smart drugs’, are substances that could improve cognitive functions and mental alertness. However, wider research is necessary to determine whether nootropic supplements are safe and effective for humans in the longer term.

The FDA do not regulate dietary supplements in the same way as medications. As such, there is no recommended dosage for Lion’s Mane mushrooms and the safety and quality of products may vary from retailer to retailer. As always, it is advisable to consult your healthcare professional before starting any new medication in case of side-effects or a clash with existing ADHD medications.
