What You'll Learn
Health benefits of mushroom supplements
Mushrooms have been used for their medicinal properties for centuries, especially in Asian regions. They are nutrient-dense and low in calories, making them a healthy addition to any diet.
Mushrooms are a good source of selenium, vitamin D, vitamin B6, and ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. They also contain polysaccharides, which are linked to improved insulin resistance and GI health. The polysaccharides in mushrooms pass through the gut to the colon, encouraging good bacteria to grow along the way.
Mushrooms are also a good source of potassium and are loaded with heart-healthy compounds that help prevent plaque buildup on arterial walls. They are naturally low in sodium, which helps to keep blood pressure low. Shiitake mushrooms, in particular, help to keep cholesterol levels low.
Research suggests that mushrooms may also have brain-boosting benefits. Studies indicate that eating 2 cups of mushrooms each week can cut the risk of developing cognitive impairment in half. Lion's mane supplements are thought to support cognitive health and help with focus and memory.
It is important to note that while mushroom supplements are available, they are not regulated and may not offer the same benefits as eating the whole mushroom. It is always best to prioritize eating a variety of whole foods first and consult a healthcare professional before taking any supplements.

Risks and side effects
While mushroom supplements may offer several health benefits, they also carry potential risks and side effects. Here are some key considerations:
Firstly, individuals with allergies to fungi should be cautious as mushroom supplements may trigger allergic reactions, including skin rashes. Additionally, those with autoimmune diseases or mushroom allergies are advised to exercise caution. Pregnant or breastfeeding women, as well as individuals on immunosuppressive medications, should consult their healthcare provider before consuming mushroom supplements.
The quality and source of mushroom supplements are crucial. Some products may be contaminated or may not meet the claimed potency, leading to potential harm. It is recommended to purchase supplements from reputable manufacturers and follow the recommended dosage to avoid adverse effects such as nausea, diarrhea, or an upset stomach.
Furthermore, the effects of mushroom supplements can vary depending on the specific type of mushroom and the individual consuming it. While some mushrooms may improve cognitive function, there are reports that lion's mane supplements may contain phytoestrogen, which could stimulate the growth of certain breast cancer cells. Reishi mushrooms, known for their stress-relieving properties, can also lower blood pressure, so they should be avoided when taking blood pressure medication.
It is worth noting that the majority of health claims regarding mushroom supplements lack sufficient clinical trials and human studies to support them. The extraction process and dosage of active compounds can vary, making it challenging to determine the exact contents of mushroom-based products. Therefore, it is advisable to consult a healthcare professional and exercise informed judgment when considering mushroom supplements.

Lack of scientific evidence
While mushroom supplements are often marketed as a cure-all, the scientific evidence to support these claims is lacking. Mushroom supplements are derived from various mushroom types, including reishi, maitake, and lion's mane, and are available in powder, capsule, and tincture form. Proponents of mushroom supplements claim that they offer a range of health benefits, such as improved cognitive function, enhanced immune system, and reduced stress levels. However, the majority of these claims are not supported by well-designed clinical trials on humans.
For example, chaga mushrooms, which grow on birch trees, are said to prevent wrinkles, counter IBD, and fight bacterial and viral infections. Similarly, cordyceps militaris, also known as the "zombie fungus," is reported to improve exercise performance, act as an antidepressant, and boost female libido. However, these claims are not backed by rigorous scientific studies. While some studies have been conducted, such as the one examining the impact of maitake mushroom extract on breast cancer patients, the majority of data comes from laboratory and animal studies, not human trials.
Additionally, the quality and safety of mushroom supplements can be questionable. The levels of active compounds in these supplements can vary depending on factors such as cultivation age and extraction methods. Contamination and toxicity may also be concerns, and overconsumption can lead to digestive issues. Furthermore, individuals with certain health conditions, such as autoimmune diseases or mushroom allergies, should exercise caution when consuming mushroom supplements.
It is worth noting that the effectiveness of mushroom supplements depends on the specific type and dose taken. While some studies suggest potential health benefits, such as improved cognitive function in older adults with mild cognitive impairment, the research is still ongoing and does not support all the health claims made by supplement manufacturers. As a result, consumers should be cautious when purchasing mushroom supplements and consult with healthcare professionals before incorporating them into their routines.

Quality and safety concerns
Quality and safety are important concerns when considering mushroom supplements. While some sources suggest that mushroom supplements can provide various health benefits, it is important to approach these claims with caution. Many of the purported benefits of mushroom supplements are not supported by well-designed clinical trials on humans, and the research in this area is still ongoing.
One issue is that the health effects of mushroom supplements can depend on a variety of factors, including the specific type of mushroom, the dose, the age of cultivation, the growing medium, and the part of the mushroom used. This makes it difficult to standardise and regulate mushroom supplements, and to determine the specific effects of different products.
In addition, the extraction and manufacturing processes can affect the quality and potency of mushroom supplements. Some products may contain contaminants or may not meet the claimed potency, leading to ineffective or potentially harmful results. It is therefore important to source mushroom supplements from reputable manufacturers and to follow the recommended dosage to avoid potential side effects such as digestive issues.
Individuals with certain health conditions, such as autoimmune diseases, mushroom allergies, or low blood pressure, should exercise caution when considering mushroom supplements. Pregnant or breastfeeding women and people on immunosuppressive medications should also consult their healthcare provider before using mushroom supplements.
Furthermore, it is worth noting that consuming whole mushrooms as part of a balanced diet may provide more benefits than taking supplements. Culinary mushrooms, such as shiitake, are rich in fibre and can support a healthy microbiome. Cooking with mushrooms adds flavour and nutrition to a dish, and they can also be used as a meat alternative.

Alternatives to supplements
While mushroom supplements are popular, they are not always suitable for everyone. For example, they are not recommended for children under 7, as their immune systems are still developing. Additionally, individuals with certain health conditions, such as autoimmune diseases, mushroom allergies, or blood pressure issues, should exercise caution. Pregnant or breastfeeding women and people on immunosuppressive medications should also consult their healthcare providers before using mushroom supplements.
- Whole Mushrooms: Nutritionists recommend consuming whole mushrooms, such as maitake, shiitake, and lion's mane, which offer fiber and nutrients that may not be present in supplements. These mushrooms can be easily incorporated into various dishes like stir-fries, omelets, or soups.
- Adaptogens: Adaptogenic herbs, such as maca root and ginkgo biloba, can provide similar benefits to mushroom supplements, including increased energy without the jittery side effects of caffeine. These adaptogens can be found in powder form and blended with other ingredients like lion's mane mushroom and B vitamins for a natural energy boost.
- Culinary Mushrooms: Culinary mushrooms, while not providing the same medicinal properties as functional mushrooms, are still an excellent addition to your diet. They are rich in fiber, which supports a healthy microbiome, and they add a savory "umami" flavor to your meals.
- Traditional Remedies: Traditional and ancient remedies have long used various types of fungi for healing purposes. For example, amadou, a spongy fungus, was used by Hippocrates to reduce inflammation, and Native American cultures used puffball mushrooms to stop bleeding and aid wound healing. Exploring traditional remedies that incorporate fungi may offer alternative ways to harness the potential benefits of mushrooms without relying solely on supplements.
It is important to remember that, while supplements can be convenient, a balanced diet that includes a variety of whole foods, including mushrooms, is always recommended. Consult with a healthcare professional or a registered dietitian to determine the best approach for your specific needs and to ensure that any supplements or dietary changes are safe and appropriate for you.
