The hericium erinaceus mushroom, better known as Lion’s Mane mushrooms, is one of the few medicinal mushrooms scientifically proven to enhance cognitive function and increase contrast sensitivity. (1)

Lion’s Mane has also been shown to promote NGF (nerve growth factor) production, which can improve memory and nerve health.

Mushrooms can be easily added to your diet and enjoyed in many ways. Mushroom teas have gained popularity as a convenient way to incorporate mushrooms into your daily routine.

Antioxidants

Mushrooms are a delicious addition to the diet, providing vitamins and minerals with few calories. They also offer anti-inflammatory properties and can help to reduce oxidative stress. Some mushrooms, including Hericium erinaceus (better known as lion’s mane mushroom) and Ganoderma lucidum, are being studied for their ability to promote brain health. They appear to have the potential to stimulate the production of anti-inflammatory cytokines that protect the cells of the nervous system and prevent neuroinflammation (3).

Reishi mushrooms are also a powerful adaptogen that can support the healthy activation of immune function and the reduction of oxidative stress (4). They can help to balance Shen disturbances and reduce the symptoms of anxiety and depression by nourishing the adrenal glands and promoting the healthy release and circulation of cortisol (5). This supports a healthy inflammatory response in the brain and body and helps improve overall cognitive function (6).

A study published in 2021 found that lion’s mane mushroom (Hericium erinaceus) may have the potential to slow or prevent Alzheimer’s disease by stimulating nerve growth and decreasing the buildup of beta-amyloid plaques associated with this condition (7). More research is needed in this area, however.

In another study, a group of elderly people who took a supplement with lion’s mane mushroom experienced improved memory performance and mental clarity. The researchers theorize that this effect is a result of the mushroom’s antioxidant activity and its ability to inhibit oxidative damage to the nervous system. Further, the supplement was shown to reduce symptoms of mild cognitive impairment in a clinical trial (8). More research is needed to test this hypothesis, however.

Vitamins

Mushrooms are a great source of vitamins and minerals that can help improve brain health. Vitamin E, for example, helps to prevent oxidative stress in the body, which can cause damage to cells and decrease mental functioning with age. Vitamin D is another important nutrient for the brain that can increase neurogenesis and cognitive function.

Medicinal mushrooms like Lion’s Mane (Hericium erinaceus) can help to improve memory by stimulating the release of NGF, which is known to promote new neurons in the brain. It also contains hericenones and erinacines, which are thought to boost synaptic communication in the brain and enhance neuron repair.

These mushrooms can also reduce oxidative stress and improve mood. Chaga mushroom, for example, has been shown to activate the Nrf2 pathway, which encourages cellular detoxification and increases antioxidant production. This may be why chaga is a popular choice among athletes, entrepreneurs and hard-working people who want to elevate their peak performance.

It’s also important to consider other ingredients in a supplement before taking it. Many supplements contain a wide range of ingredients that can deliver different benefits depending on the formula. This can make it difficult to decide what product is best for your personal goals.

While many people take supplements to support brain health, the Global Council on Brain Health recommends consuming most of your nutrients from whole foods. Specifically, the GCBH suggests that you should focus on eating high-quality proteins, healthy fats, low-sodium salt and no processed or refined sugars. This approach can help you to avoid some of the most common brain-health issues such as obesity, heart disease and dementia. This is because these dietary choices are associated with slower rates of cognitive decline and reduced risk of Alzheimer’s.

Minerals

Medicinal mushrooms like Lion’s Mane (Hericium erinaceus) have been shown to help improve memory by stimulating the release of Nerve Growth Factor (NGF) in the brain. NGF is responsible for improving synaptic communication and helping your body repair existing connections. Lion’s mane has also been shown to promote neurogenesis in the hippocampus, which is the part of your brain that stores memories and makes new ones.

This mushroom is rich in a group of compounds called polysaccharides, which are made up of b-glucans. These are known to boost immune function, reduce oxidative stress, and improve cognitive performance.

Studies have found that these mushrooms may stimulate the production of gamma-linoleic acid, which is known to help prevent cellular aging and protect neurons from toxic damage. (2)

They also contain other important nutrients like iron, magnesium and zinc that contribute to healthy blood flow to your brain. Another important mineral for the brain is selenium, which helps to regulate glutathione levels. Glutathione is a master antioxidant that contributes to the maintenance of normal brain activity and neuroplasticity. It is also crucial to spatial memory.

Adaptogens like Lion’s Mane and Reishi mushrooms are also extremely beneficial for the brain because they work to calm the nervous system, which can lead to better sleep and a stronger mental state. In addition, Reishi and Turkey tail mushrooms have been shown to support the lungs and the respiratory tract, which is important for maintaining optimal breathing and heart health. This is critical for ensuring that your blood is properly circulating throughout your body and into the brain, where it is needed to keep you alert and focused. (3)

Adaptogens

Adaptogens are natural herbs that help the body cope with stress and maintain balance. These plants are thought to stimulate the central nervous system and improve cognitive function, such as attention, memory and motivation. They also reduce fatigue and enhance mental performance during chronic stress. Adaptogens have been shown to have antidepressant-like effects, and are used in the treatment of anxiety, depression, immune dysfunction, sleep disorders and chronic fatigue.

Studies have shown that Rhodiola rosea, Schisandra chinensis and Eleutherococcus senticosus have positive effects on mental health by reducing symptoms of fatigue, improving attention and mood. These benefits are believed to be attributed to their ability to regulate the HPA axis and rebalance cortisol levels.

When the body experiences physical or emotional stress, it goes through a general adaptation syndrome. Adaptogens hack the stress response, increasing non-specific resistance and decreasing sensitivity to stressful stimuli. They also prolong the phase of resistance by providing a stimulating effect that holds off exhaustion. This allows you to stay in the resistance stage longer, allowing your brain and body to better deal with the stressors and maintain a healthy state of equilibrium.

Adaptogens can be found in a variety of foods and supplements. They are commonly incorporated into tea blends, such as Rhodiola and Panax ginseng tea, and can also be consumed in the form of powder or capsules. It is important to consult with a naturopathic physician before taking any supplements, including adaptogens, as they may interact with some medications. They can recommend the appropriate dosage strength and formula and advise on how to use these herbal remedies to best support your unique health needs. iHerb offers a wide selection of herbs and supplements, including many adaptogens, at an affordable price.

Nootropics

Nootropics (pronounced noh-U-TROP-iks) are natural, semi-synthetic or synthetic substances that purportedly improve cognitive functions such as executive function, attention and memory. They are found in dietary supplements, nutraceuticals and energy drinks. They also are available as prescription and non-prescription pharmaceutical drugs for specific conditions such as ADHD.

Some examples of nootropics include caffeine and choline. They act by increasing the availability of acetylcholine in neurons, improving the synthesis and uptake of phosphatidylcholine (a molecule used to form cell membranes), and by modulating the processing of APP (amyloid precursor protein).

In addition, they have antihypoxic properties, increase the elimination of oxygen free radicals, stimulate phospholipid metabolism in neurohormonal membranes and promote cellular plasticity through AMPA receptor activation. These effects have been demonstrated in a variety of brain cells including neurons and astrocytes.

Many people take nootropics to boost their intelligence and focus. But there is little clinical evidence of their effectiveness. Moreover, they may have harmful or unpleasant side effects such as nausea, fatigue and insomnia. They may also interact with other medications, supplements and over-the-counter or illicit drugs.

Unlike conventional medications, nootropics are not regulated by the Food and Drug Administration. However, they can be safe when taken under the supervision of a doctor. They have low toxicity and few side effects, compared to psychotropic drugs that cause significant sedation and are associated with a high risk of abuse and addiction. Nootropics can improve mental performance in healthy individuals by enhancing concentration, motivation, creativity and memory. They are also thought to protect against age-related brain degeneration. Nevertheless, their benefits vary depending on genetics, dosage and overall baseline health. They are more effective when taken regularly.
