Cordyceps mushrooms are generally considered safe, but may have negative side effects
Cordyceps mushrooms are generally considered safe to consume, but there is limited research on their health effects and possible side effects. While they are not traditional mushrooms, they have been used in traditional Chinese and Eastern medicine for their purported health benefits.
Cordyceps is a composite genus of fungi that grows on specific insects and arthropods, consuming them from the inside out. There are over 600 species of Cordyceps mushrooms, most of which are found in Asia. The two most commercially available types are wild Cordyceps sinensis and its cultured mycelium substitute. Wild Cordyceps sinensis is rare and expensive, costing up to $20,000 per kilogram.
Cordyceps has been studied for its potential health benefits, including boosting energy, supporting heart health, reducing inflammation, and fighting cancer cells. It has also been used to enhance immunity, improve kidney health, and regulate blood sugar levels. However, there is limited conclusive research on the effectiveness of Cordyceps, and it is not recommended as a treatment without further study.
While generally considered safe, Cordyceps may cause mild side effects such as upset stomach, nausea, diarrhea, and loose stools. People with certain medical conditions, such as autoimmune diseases, should avoid consuming Cordyceps as it may activate the immune system and worsen symptoms. Pregnant and breastfeeding women are also advised to avoid Cordyceps due to a lack of research on its safety during these periods. Additionally, Cordyceps may increase the risk of bleeding during surgery, so it is important to inform your doctor if you are taking it.

They are used in traditional Chinese medicine for their anti-fatigue, anti-aging and anti-cancer properties
Cordyceps is a fungus that grows on insects and has been used in traditional Chinese medicine for centuries. It is said to have several health benefits, including anti-fatigue, anti-aging, and anti-cancer properties.
In traditional Chinese medicine, cordyceps is believed to boost energy and support overall health. It has been used to treat various conditions, including fatigue, aging, and cancer. While it is generally thought to be safe, there is limited research on the potential side effects of consuming cordyceps.
The anti-fatigue property of cordyceps is one of its most well-known benefits. It is said to boost energy and reduce fatigue, making it a popular choice for those seeking increased stamina and endurance. Some studies have shown that cordyceps can enhance athletic performance, although more research is needed to confirm this.
The anti-aging property of cordyceps is also notable. Some research suggests that cordyceps may help to limit some of the naturally occurring changes due to age. For example, a 2022 study found that cordyceps may help to improve overall heart health and cholesterol levels, which can decline with age. Additionally, cordyceps' anti-inflammatory properties may also contribute to its anti-aging effects, as inflammation is a key driver of the aging process.
Lastly, cordyceps has been studied for its potential anti-cancer properties. Lab studies have shown that cordyceps may have antitumor effects and can potentially kill cancer cells. For example, one study found that cordyceps helped to shrink tumor size in lung and skin cancers. However, more clinical research is needed to confirm these effects in humans.
While cordyceps has been used safely in traditional Chinese medicine for centuries, it is important to note that it may not be suitable for everyone. Some possible negative side effects include upset stomach, nausea, and loose stools. Additionally, people with certain medical conditions, such as autoimmune diseases, should consult a doctor before consuming cordyceps, as it may activate the immune system.

There is some evidence that cordyceps may improve kidney health
Cordyceps is a medicinal fungus that infects insects and arthropods, growing inside its host and eventually killing it. It has been used in traditional Chinese medicine for its anti-fatigue, anti-aging, and anti-cancer properties. The fungus has also been studied for its potential health benefits, such as reducing inflammation, boosting energy, and supporting heart health.
While cordyceps is generally thought to be safe to consume, there is limited research on its health effects and possible side effects. Some studies have shown that cordyceps may cause gastrointestinal issues like nausea, diarrhea, and loose stools. People with certain medical conditions, such as autoimmune diseases, should also avoid consuming cordyceps as it may activate the immune system.
Despite the limited research on the health effects of cordyceps, there is some evidence that it may improve kidney health. In one large-scale study, cordyceps lowered creatinine levels in people with chronic kidney disease. Additionally, cordyceps protected the kidneys from toxic drugs, complications of diabetes, and transplant rejection.
Cordyceps militaris, in particular, has been found to improve chronic kidney disease by affecting the TLR4/NF-κB redox signaling pathway. A three-month treatment with cordyceps militaris resulted in a significant reduction in urinal protein, BUN (blood urea nitrogen), and creatinine levels in CKD patients. This suggests that cordyceps militaris can improve kidney function and control blood levels of these substances.
Overall, while cordyceps may offer potential health benefits, including improved kidney health, more research is needed to fully understand its effects and safety. It is always recommended to consult with a healthcare professional before consuming cordyceps or any other supplement.

Cordyceps may cause gastrointestinal issues like nausea, diarrhea, and stomach upset
Cordyceps mushrooms are generally considered safe for consumption, and have been used in traditional Chinese medicine for their purported anti-fatigue, anti-aging, and anti-cancer properties. However, as with any supplement, there are risks involved.
The potential for these gastrointestinal issues highlights the importance of understanding one's own medical history and consulting a healthcare provider before incorporating Cordyceps into one's diet or supplement regimen. While generally considered safe, Cordyceps may not be suitable for everyone, especially individuals with certain pre-existing medical conditions.
For instance, people with autoimmune diseases, including multiple sclerosis, inflammatory bowel disease, celiac disease, or rheumatoid arthritis, should refrain from consuming Cordyceps. This is because Cordyceps can activate the immune system, potentially exacerbating the symptoms of these autoimmune conditions.
Additionally, individuals taking blood thinners or those diagnosed with Type 2 diabetes may want to avoid Cordyceps as it could cause a dangerous drop in blood sugar levels. This is a critical consideration that underscores the necessity of seeking professional medical advice before consuming Cordyceps or any other supplement.
