Monks prepared it to be the active ingredient in a tonic to support the good health of the heart, liver, lungs, spleen, and kidneys. They believed that it could replenish internal health, aid digestion and regulate the Qi. Also used as a ‘brain tonic’, it was often taken in tea as an aid to concentration before meditation.

The powder had several uses but was most often used to speed up the healing of open wounds. In Europe, there were times it was such a delicacy that it was reserved for royalty.

What are the health benefits of Lion’s Mane?

Since interest in this incredible mushroom has increased, scientists have conducted investigations to broaden our understanding of its effects. They have primarily focused on its role in promoting brain health, but some have investigated its impact within the entire body:

Brain function and memory

brainLion’s Mane is often referred to as a nootropic, which is a substance that can boost memory and mental capacity. It is thought to help some people improve their focus and clear brain fog. A study conducted with older adults showed that 3g daily caused a significant improvement in mental function. 

Research conducted with animals has also demonstrated that preparations containing Lion’s Mane can stimulate the growth of brain cells and reduce the symptoms of memory loss. Currently, there is no conclusive evidence, but there is a good indication that it can cause several actions that could improve symptoms of Alzheimer’s disease.

There is also a growing indication that it may be of use to reduce the damage caused when the brain or nervous system is injured. Research with rats showed that the recovery time from brain damage could be reduced by up to 41% by Lion’s Mane extract. 

Lower triglyceride levels and improved heart health

Some studies show that, when eaten, Lion’s Mane can speed up the reactions that breakdown fats and reduce triglyceride levels in the blood. These may indicate that Lion’s Mane could be able to reduce the risk of heart disease. It also exhibits several other features which could prevent heart-related issues, such as stopping cholesterol from oxidising in the blood and reduced blood clotting rates.

Reduced inflammation

Research has also had success linking inflammation to a broad range of diseases and chronic conditions. Inflammation is a natural swelling that occurs in the body during illness or injury. It’s part of the healing process but sometimes it can occur when it’s not needed. This type of swelling has been linked to a broad range of diseases, chronic illnesses and mental health conditions.

Studies with mice found that Lion’s Mane provides anti-inflammatory factors that can lessen depression-like symptoms. Other animal investigations showed that an alcohol-based Lion’s Mane tincture could effectively reduce chronic inflammation.

Are there any side effects?

Lion’s Mane mushroom has an excellent safety profile, and the only negative effects observed during studies were mild; These effects were specifically linked to allergic responses and included shortness of breath, itchy skin and a rash.

Lion’s Mane is consumed safely in many countries across the world and studies with rats have shown that it’s not addictive. In most cases there are no ill effects, even when taken in more significant amounts.

How much should I take per day?

The studies that reported positive effects from Lion’s Mane used daily Studies with mice found that Lion’s Mane provides anti-inflammatory factors that can lessen depression-like symptoms. amounts of between 750mg and 5g. The current evidence indicates that you will begin to notice effects if you take a daily measure in this range. However, some supplements use specially prepared extracts that provide a more concentrated amount of the active ingredients. In these cases, they may provide more significant results with a smaller measure. For the best results, you should always follow the directions on the packet.

What forms does it come in? 

Lions mane mushroom cooked

Lion’s Mane is a versatile food and can be consumed in several different forms:

  • Cooked and eaten with your meal – When cooked, Lion’s Mane has a pleasant flavour similar to seafood. Cooking and eating it is a great way to get the complete range of nutrients, but not everyone has a large enough supply to keep eating it daily.
  • Mushroom tea – The mushroom can be shredded and dried to form a delicious tea. The introduction of hot water to the mushroom flesh breaks it down and releases higher levels of nutrients and active ingredients into the liquid.
  • Ethanol or hot water extracted supplements – Just like in tea, the addition of hot water or ethanol releases the beneficial substance from within the cells. These extraction methods are often used to prepare supplements and allow manufacturers to place concentrated extracts into small capsules. This is the most convenient method to take Lion’s Mane regularly.
  • Freeze-dried fruiting bodies – The freeze-drying process prevents the mushroom from decaying. This ensures that it still contains all of its valuable substances when you’re ready to eat it. Supplement makers often add freeze-dried Lion’s Mane to capsules or combine it with other types of extract.

What should I look for when making a purchase?

Lion's Mane Mushroom

If you choose to buy a Lion’s Mane supplement, look for trustworthy, organically certified brands that use all parts of the fruiting body and mycelium. It is also essential to choose organic and, preferably, organically certified because mushrooms act as bio-accumulators and can easily be contaminated by the pollutants of their environment (air, soil, water).

By choosing an organic brand, you know that they’ve had to meet strict criteria and their products have been thoroughly inspected by an official organic authority, such as the UK Soil Association. Products that contain all parts of the mushroom have a broader range of the mushroom’s active ingredients, making them more effective.

These organic Lion's Mane capsules by Mushrooms 4 Life contain 1000mg of freeze-dried biomass and fruiting body at the ideal ratio. They have also been third-party tested, DNA tested and screened for any traces of heavy metals, pesticides or contaminants. Take two per day, 1-3 times per day to feel the benefits of Lion's Mane.


The Lion’s Mane mushroom has an incredible history of being used in powders, tonics and elixirs. Several ancient civilisations were aware of its effects and successfully harnessed them in different ways.

We, however, still have some way to go before we fully understand the full scope of its actions and how they can improve our lives. What we do know strongly indicates that it has excellent potential as a food supplement.
