The Mental Health Mushroom

Effects on Cognitive Function

Who doesn’t have trouble with their brain now and again? From memory problems to focus issues, we’ve all been there, and we understand the difficulties these can cause which is why we want to help.

You may be struggling with more than the average amount of brain fog because of a diagnosed problem or lifestyle factor. Either way, Lion’s Mane mushroom is there to help whether you want to take it for a few weeks or a few years.

Studies have shown that in just 12 weeks you’ll see the big effects, like recognition memory and spatial awareness.

If you’re seeing age-related cognitive decline (thinking or memory problems to us non-scientists), you can start seeing an improvement in mild symptoms from just four weeks.

Of course, if you want to see these results become more potent and remain, you need to consider taking these powerful fungi as a long-term aid.

Inflammation & Oxidative Stress

What does inflammation and oxidative stress mean? Well, these things are usually the background bug in your system causing all kinds of havoc, from digestive issues to chronic diseases.

There haven't been any detailed studies yet on how long it takes Lion’s Mane mushrooms to produce their anti-inflammatory effects in your body. However, some evidence suggests taking it for at least four weeks can let you start seeing the benefits of Lion's Mane.

The crucial thing to remember here, and for all of the benefits, is that the time it takes for Lion’s Mane to have a full effect will depend on the severity of your condition as well as the dosage you’re taking.

Don’t expect a miraculous result if you take five grams for a week. Take it slow and test out what works best for you in the long term.


Diabetes probably isn’t the first thing you’d think a mushroom supplement could help with. But give this mighty mushy some credit. Research has suggested that Lion’s Mane mushroom powder takes just four to six weeks to improve blood sugars and regulate the amount of insulin produced in people with diabetes.

That means by taking a simple supplement, these people saw a clear decrease in something called serum glucose levels, which is basically how much sugar is floating around in your blood.

It also levelled out the amount of insulin their pancreas produced, meaning their sugar levels weren’t fluctuating so often. For a diabetic person, these results could be life-changing.


There’s nothing wrong with being bigger, but if you’re struggling with obesity and unmanageable weight gain, Lion’s Mane could be your go-to guy.

Taken orally as a powder, Lion’s Mane could potentially reduce the amount of fat your body accumulates, according to an animal study. At the same time, it can balance out your bad cholesterol levels, keeping you healthier for longer.

However, be prepared to take this supplement for a longer period, because these effects were noted after 28 days, giving the mushroom’s chemical properties time to do their work.

At the same time, Lion’s Mane can help with the issues that sometimes go along with obesity, such as high blood pressure, arthritis and nerve pain or damage. Within about four weeks, you can start seeing these effects too.

Alzheimer’s Disease

Sadly, Alzheimer’s and dementia are potentially long-term diseases, so long-term doses of Lion’s Mane are needed. Since it’s a complicated issue that affects your brain function in all sorts of ways, Lion’s Mane needs a little longer to fight these symptoms to improve your brain health.

However, just one gram of Lion’s Mane taken daily for 49 weeks has been shown to improve brain function test scores taken by people with mild Alzheimer’s.

Since this disease is so prevalent and unforgiving, we’re glad little ol’ Lion’s Mane can be so powerful in the face of these symptoms.

Stomach Ulcers

Ulcers who? Scientific research has proved that Lion’s Mane mushroom is one of the best mushrooms for your overall gut health. Studies show that in two to four weeks of taking fruiting body supplements, you’ll even be able to fight off potential stomach ulcers.

Stomach ulcers are often caused by conditions like Crohn’s and ulcerative colitis, and sometimes even your dietary choices if you’re naturally more likely to get ulcers in your tummy.

Luckily, in 2016 a study gave individuals diagnosed with these kinds of conditions a Lion’s Mane supplement (and not even a very strong one).

The results show that everyone saw a significant reduction in their symptoms and noted an improvement in their general quality of life within just three weeks; pretty cool for a little shroom.


Are There No Negative Side Effects?

It’s true; you can take Lion’s Mane long-term with no negative side effects. In fact, you’ll only start seeing more potent Lion's Mane health benefits and more reliable results. Make the most of your mind with medicinal mushrooms, and get on the path to a better, healthier life!
