Personal Lion’s Mane Experiences (This Is What Happened After 90 Days)

| Leestijd 10 Minuten

In this article, we share some personal experiences with Lion’s Mane. Both from our customers and ourselves. Not everyone has the same experience, as every body is different. The aim of this article is to give the best possible insight into the various effects people experience with this “mushroom for the brain”.

What do people use Lion’s Mane supplements for?

writing down personal experiences with Lion's Mane

Many people who take Lion’s Mane supplements do so to improve their memory, mood and/or focus. The Lion’s Mane mushroom is also considered a nootropic (a substance that can improve cognitive functions).

Results of several scientific studies indicate the possible positive effects of Lion’s Mane on mood and cognitive functions. There are some studies suggesting that Lion’s Mane can reduce feelings of depression and anxiety (1, 2).

Also, some studies suggest that Lion’s Mane has neuroprotective properties (3, 4). That means that Lion’s Mane can possibly stimulate the growth of nerve cells in the brain, which is important for mental recovery and reducing the risk of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.

Lion’s Mane experiences: What do our customers say?

We asked some of our customers about their experience with our Lion’s Mane supplements. Here’s what they said:

Geert: “There’s a lot of hype online about Lion’s Mane, so I thought I’d try it out without too many expectations, because it’s just a supplement, haha. But, and this is definitely not a placebo effect, my focus and access to my short- and long-term memory have improved. No extreme changes, but I do notice that I remember things easier and that I can express myself more clearly.”

Dani: “Many supplements have no effect on me at all. But with Lion’s Mane, I notice a clear difference. I have more focus, I’m more comfortable in my skin, and my brain fog also seems to be over.”

Mirthe: “I was suffering from tingling feet because of nerve damage. On the internet, I read a bit about Lion’s Mane and people’s experiences with this supplement. And, of course, I also looked into research. Four months ago, I ordered Lion’s Mane from MushPeak, taking vitamin B1 every day. Right now, my feet feel ten times better and I hope it stays that way!”

What our editor experienced after 90 days of Lion’s Mane

“In 2020, I was suffering from chronic gut problems and a negative mood,” Jessica, our editor, tells us.

“By immersing myself in gut health, I found out that around 80-90 per cent of your serotonin, your happiness hormone, is produced in your gut. If you have chronic gut inflammation, it can also affect your serotonine production and thereby your mood. So I decided to rigorously change my diet and make my digestion as easy as possible.”

“By just eating more simply for a few weeks, I soon noticed a difference. Six months later, I felt like everything was a bit more balanced.”

“However, I still had regular problems with my concentration. I often lost focus quickly and forgot what I wanted to do 10 times in a day as soon as I walked into another room.”

“I did take supplements before, but at that time I wasn’t taking anything at all. Then I came across mushroom supplements. And after having read other people’s experiences with Lion’s Mane, I decided to try it too.”

“I don’t really believe in 30-day tests, which I think is too short to really notice a difference. That’s why I went for 90 days. At the beginning of the first month, I didn’t really feel much difference. My energy level was the same, my bowel movements were the same, and my concentration was the same.”

Month 1: “By the end of the month, I was sleeping better”

“Towards the end of the first month, I did notice that I started getting more energy. I also slept better. Whether this is due to Lion’s Mane, no idea. Research does say it can improve sleep quality, so chances are it was due to Lion’s Mane.”

Month two: “I no longer needed to check my calendar 80 times per day”

“By the second month, things were much clearer for me. Usually, I struggle with juggling multiple tasks, but this time around, it was a lot easier. My focus and memory got better too. I didn’t have to check my planner constantly to remember appointments because I had everything stored in my head.”

Month three: “Very positive experience with Lion’s Mane”

“In month three, I was still sleeping soundly. The times I forgot something decreased, and I started training for the marathon. I really didn’t imagine myself doing that before.”

“My experience with Lion’s Mane has been a positive one. I’m also taking other mushroom supplements now, including Cordyceps. The combination of Lion’s Mane and Cordyceps works tremendously well for me. To see what it does for others, I definitely recommend people to try it for themselves.”

Does Lion’s Mane have side effects?

Nothing is always positive all the time. There are people who don’t notice anything about a supplement or don’t benefit from it. So far, we have only received positive feedback about Lion’s Mane from our customers, and we are very satisfied with it ourselves. As far as we know, Lion’s Mane does not have many side effects either.

A quick search on the internet does show that there are people with negative experiences. These are mainly people with strong allergies. Lion’s Mane can possibly interact with certain medications, including antihistamine. Antihistamine is used to treat allergic reactions and can cause drowsiness as a side effect.

Lion’s Mane could enhance the effect of antihistamines, which can make a person even more drowsy – especially at high doses. So if you’re on medication, always ask your doctor if you can combine it with supplements (whatever supplements).
