Mushroom supplements have become increasingly popular, with manufacturers claiming a wide range of health benefits, from anti-aging and anti-cancer effects to enhanced athletic performance and improved sleep quality. However, there is limited scientific evidence to support these claims, and the supplement market is largely unregulated, allowing manufacturers to make unsubstantiated assertions about their products' efficacy. While some studies have shown promising results in cell cultures and animal models, human clinical trials are scarce and often limited in scope. As a result, consumers are advised to be cautious and critical when evaluating the purported benefits of mushroom extracts.

What You'll Learn
Lack of regulation
The lack of regulation in the mushroom extract market has led to a variety of issues, including misleading marketing claims, product quality concerns, and potential health risks.
Firstly, the absence of strict regulations has resulted in a proliferation of mushroom products with unsubstantiated health claims. Companies selling mushroom extracts often make bold assertions about their purported benefits, ranging from treating anxiety and allergies to fighting cancer and improving athletic performance. However, as Nicholas Money, a biology professor at Miami University in Ohio, points out, these marketing claims often go far beyond what is supported by scientific evidence. The lack of regulation allows manufacturers to make unproven claims without providing experimental evidence to back them up.
Secondly, the lack of formal quality regulations in the supplement industry, as described by one expert as the "Wild West," means that consumers cannot always be certain about the quality and effectiveness of the mushroom products they are purchasing. The extraction process and the type of mushrooms used can vary significantly between products, and without proper regulations, it is challenging for consumers to make informed decisions.
Additionally, the lack of regulation can lead to potential health risks. Some mushroom extracts may contain toxic compounds or interact negatively with other medications an individual is taking. Without proper oversight and monitoring, consumers may be unaware of the potential dangers associated with certain mushroom products.
Furthermore, the lack of standardized dosing guidelines for mushroom extracts is concerning. It is currently unclear what the appropriate dosage, frequency, and duration of mushroom supplement consumption should be. This lack of clarity can lead to misuse or overuse of these products, potentially resulting in adverse health consequences.
While some regulatory bodies, such as the European Food Safety Authority (EFSA), have implemented rules for nutritional health and disease risk reduction claims, the overall lack of comprehensive regulation in the mushroom extract market remains a significant issue. This lack of regulation has contributed to a situation where consumers are faced with a multitude of products making varying health claims, with little guidance on which products are truly effective and safe.

Similarly, a small study of long-distance runners published in the Journal of Exercise Physiology Online in June 2021 found that specific medicinal mushrooms could boost endurance.
Mental Health and Cognitive Benefits
Mushroom extracts, such as psilocybin, are being studied for their potential in treating mental health conditions. Research published in Molecules in May 2021 explores the possibility of psilocybin mediating emotions and moods and treating depression, migraines, and other health conditions. Additionally, Lion's mane mushroom extracts have been linked to improved cognitive test scores in older adults with mild cognitive impairment and potential benefits for those with mild Alzheimer's disease and dementia.
Cancer Treatment Support
Some mushroom extracts have been used as complementary treatments for cancer patients. Turkey tail, a type of medicinal mushroom, has been employed as a mainstream cancer treatment in Japan since the 1970s and China since the 1980s. It contains polysaccharide-K (PSK), which may stimulate the immune system and improve survival rates for people with gastric or colon cancer. Similarly, lentinan, extracted from shiitake mushrooms, has shown promising results when combined with chemotherapy for patients with stomach, prostate, colorectal, and liver cancers.
While these initial findings are intriguing, more extensive human clinical trials are necessary to conclusively determine the efficacy of mushroom extracts in promoting health and treating various conditions.

Anti-aging effects
Mushrooms contain various bioactive compounds, including carbohydrates, bioactive proteins, fungal lipids, phenolic compounds, vitamins, and minerals. These compounds have been found to possess anti-oxidant, anti-wrinkle, and anti-aging properties. The anti-aging effects of mushrooms are primarily focused on skin aging and age-related diseases.
Mushrooms have been found to have anti-inflammatory properties that can help combat stress, balance the skin, and reduce redness. They can also address skin conditions like dermatitis, psoriasis, and eczema. Furthermore, mushrooms can boost the production of collagen and elastin, which are essential for maintaining skin elasticity and reducing the appearance of fine lines and wrinkles.
Mushrooms are also a rich source of antioxidants, which can help protect the skin from free radicals that cause premature skin aging. The reishi mushroom, for example, has been shown to reduce photoaging in the skin. Lion's mane is another mushroom that supports collagen production and improves the appearance of fine lines.
In addition to their topical applications, mushroom extracts have been found to have systemic anti-aging effects. For example, extracts of the medicinal mushroom Agaricus blazei Murill have been found to enhance the functions of phagocytic cells, contributing to anti-tumor effects and strengthening the immune system, which is crucial for healthy aging.
Mushrooms with high ergothioneine content, such as shiitake mushrooms, have been studied for their potential to act as therapeutic agents in eliminating senescent cells in neurodegenerative diseases. This may help to reduce the incidence of age-related diseases such as Alzheimer's and Parkinson's disease.

Cancer treatment
Mushrooms have been used in traditional Chinese medicine for hundreds of years to treat illnesses, including lung diseases in Japan and China. They are also used to complement cancer treatments in these countries. However, it is important to note that mushrooms cannot cure or prevent cancer.
Mushrooms are packed with vitamin D, which is essential for the immune system. They are also rich in fiber, which supports a healthy microbiome. The medicinal value of mushrooms comes from extracting the bioactive compound, the active ingredient of the mushroom, and making medicinal products such as tinctures, teas, and capsules. Culinary mushrooms, on the other hand, can be a great addition to a healthy diet.
Research has been conducted to determine whether mushroom extracts can prevent or stop the growth of cancer cells. Laboratory research has shown that mushroom extracts may slow the growth of breast cancer cells and have anticancer effects on skin, lung, and prostate cancer cells. However, it is important to note that substances that can kill cells in laboratory conditions may not translate into effective treatments for humans.
Some studies have shown that cancer patients who consume mushrooms may have improved survival rates, possibly due to a positive immune response or other factors. Mushrooms have been linked to improvements in several quality-of-life indicators for cancer patients, including improved appetite, physical and mental competency, and reduced fatigue. Additionally, mushrooms may help reduce the side effects of chemotherapy, such as nausea, bone marrow suppression, anemia, insomnia, and loss of appetite.
It is important to consult with a doctor before using mushrooms during cancer treatment, as they contain potent biological compounds that can behave like drugs. While mushroom extracts have shown potential as complementary treatments for cancer, more research is needed to fully understand their effectiveness and any potential side effects.
