What You'll Learn
Reishi mushroom's antioxidant properties
Reishi mushrooms, also known as Ganoderma lucidum, have been used for centuries in traditional Chinese medicine to boost immunity and promote overall health. Recent studies have also found that the mushroom's bioactive compounds have medicinal properties that may be beneficial in treating Alzheimer's disease.
Alzheimer's disease is a neurodegenerative disorder characterised by cognitive impairment, memory loss, and psychiatric abnormalities. The disease is caused by the accumulation of beta-amyloid plaques and neurofibrillary tangles in the brain, which leads to the degeneration of neurons. Oxidative damage has also been linked to the development of Alzheimer's.
Reishi mushrooms have potent antioxidant properties due to their active biomolecules, including terpenes such as ganoderic acid. These antioxidants can help protect the brain from oxidative damage, thereby reducing the risk of age-related cognitive impairment. In addition, the antioxidants in reishi mushrooms can alleviate neuronal damage and inhibit apoptosis, or cell death, in the brain.
Research has shown that supplementation with reishi mushroom extract can reduce the likelihood of mild cognitive impairment and improve cognitive deficits in rodents with Alzheimer's disease. One study found that reishi mushrooms improved cognitive ability and increased longevity in rodents. Another study on rats with Alzheimer's disease found that reishi mushrooms ameliorated non-spatial learning and memory deficits.
The potential therapeutic benefits of reishi mushrooms in treating Alzheimer's disease are promising, and further research and clinical trials are ongoing.

Lion's Mane mushroom's nerve growth factor
Alzheimer's disease is the leading neurodegenerative disorder affecting memory and learning in elderly people. Research has shown that certain mushrooms may help prevent the formation of beta-amyloid plaques and neurofibrillary tangles, which are associated with the disease.
Lion's Mane mushrooms (Hericium erinaceus) are known for their potential to stimulate nerve growth factor (NGF) production. NGF plays a crucial role in the development and maintenance of nerve cells, which has led researchers to investigate Lion's Mane as a possible treatment for neurodegenerative diseases, including Alzheimer's.
Neurotrophic factors are important in promoting the growth and differentiation of neurons. NGF is essential for the maintenance of the basal forebrain cholinergic system. Hericenones and erinacines isolated from Lion's Mane mushrooms can induce NGF synthesis. A 2009 double-blind, placebo-controlled trial found that 50- to 80-year-old Japanese men and women with mild cognitive impairment improved after taking four tablets of Lion's Mane mushroom extract three times a day for 16 weeks.
Lion's Mane mushrooms are also known to possess neuroprotective properties, including antioxidant, anti-inflammatory, and antimicrobial effects. These properties may help protect the brain from oxidative damage, which has been linked to the development of Alzheimer's disease.
Overall, Lion's Mane mushrooms show potential in stimulating nerve growth factor production and providing neuroprotective benefits, which may have applications in the treatment or prevention of Alzheimer's disease. However, further research is needed to fully understand their efficacy and mechanisms of action.

Medicinal mushroom's bioactive compounds
Mushrooms have been used as medicine for many years. They exhibit a broad spectrum of pharmacological activities, including antibacterial, antifungal, anti-inflammatory, antiviral, antidepressive, antidiabetic, and neuroprotective activities. The pharmacological activities of medicinal mushrooms are detected through in vitro assays and in vivo studies in animal models.
Medicinal mushrooms contain bioactive compounds, which are classified as nutraceuticals. Nutraceuticals are supplements with health-promoting and disease-preventing properties. The European Food Safety Agency has approved the use of medicinal mushrooms as supplements.
Some of the bioactive compounds found in medicinal mushrooms include:
- Α- and β-glucans, which are responsible for immunomodulatory effects due to their ability to bind to specific cell wall receptors and stimulate specific immune responses.
- Terpenes, which are important for their bioactivity.
- Phenolic compounds, which are antioxidants with different mechanisms of action, including oxygen scavenging, metal inactivation, and free radical inhibition.
- Linoleic acid, which has anticancer effects on breast, colon, and prostate cancer.
- Ergosterol, a sterol that undergoes photolysis to form vitamin D2 when exposed to UV radiation.
- Ergothioneine, a powerful antioxidant that can help protect the brain from oxidative damage, which has been linked to the development of Alzheimer's disease.
Recent research has shown that bioactive compounds in mushrooms may help prevent the formation of beta-amyloid plaques and neurofibrillary tangles, which are characteristic of Alzheimer's disease. Studies have found that the medicinal mushroom cordyceps (Cordyceps sinensis) has antioxidant and anti-inflammatory effects that can prevent neuronal cell death and memory loss. Lion's Mane mushrooms have also been studied for their potential to stimulate nerve growth factor (NGF) production, which is crucial for the development and maintenance of nerve cells, making them a potential treatment for neurodegenerative diseases, including Alzheimer's.

Cordyceps mushroom's anti-inflammatory effects
Reishi mushrooms, also known as Ganoderma lucidum, have been shown to have therapeutic potential against Alzheimer's disease in rats. However, the focus of this answer will be on the anti-inflammatory effects of Cordyceps mushrooms.
Cordyceps is a genus of fungi used in traditional Chinese medicine to treat various health issues. It has been studied for its potential health benefits, including anti-inflammatory effects. While research in humans is limited, animal and lab studies suggest that Cordyceps may help fight inflammation.
One of the most well-known species of Cordyceps is Cordyceps militaris, an entomopathogenic fungus and one of the most important traditional Chinese medicines. Studies have shown that this mushroom exhibits interesting biological activities, including anti-inflammatory properties. The polysaccharide extracts from this mushroom have different effects depending on their monosaccharide composition. The alkaline extract, from which a linear β-(1→3)-D-glucan was isolated, showed the highest anti-inflammatory effect by inhibiting IL-1β, TNF-α, and COX-2 expression.
Cordyceps also contains cordycepin, which is easily extracted with ethanol and is partly responsible for the anti-inflammatory effects of these mushrooms. Additionally, β-(1→3)-D-glucan, another compound found in Cordyceps, has been shown to exhibit anti-inflammatory effects as well. In vitro studies have shown that the β-(1→3)-D-glucan of C. militaris is efficient in inhibiting inflammation of THP-1 cells.
Furthermore, a 2024 study found that Cordyceps extract exhibited antioxidant properties and increased collagen production in the skin. Antioxidants are molecules that fight cell damage by neutralizing free radicals, which can contribute to disease and aging. The ongoing history of Cordyceps use in traditional Chinese medicine suggests it is nontoxic, but more human research is needed to determine the effectiveness and safety of Cordyceps supplements for treating inflammation.
