Cordyceps Mushroom: Benefits, Dosing, Where To Buy, And More!

Cordyceps refers to a genus of 400+ parasitic mushrooms that grow on insect larvae, digesting them, and growing long sprouts that can be harvested.

Despite the somewhat disgusting origins of these fungi, they may actually have some powerful nootropic and health benefits.

And don’t worry, actually harvesting cordyceps from larvae is prohibitively expensive; most supplements use lab-grown fungus, no bug larvae involved.

Two species of cordyceps in particular, Cordyceps sinensis and Cordyceps militaris, have been used for centuries in Chinese and Tibetan medicine.

The reported health benefits include:

  • Improved athletic performance
  • Increased mood and memory
  • Higher libido
  • Anti-aging effects
  • Lower inflammation

Cordyceps Militaris cultivation and harvesting.

Folk healers have been using this fungus for an extremely wide variety of ailments. Among the Sikkim in northern India, cordyceps is prescribed for practically “all illnesses.”

And now modern medicine is starting to confirm what these cultures have practiced for ages.

According to one review of cordyceps, “many studies support C. Sinensis having diverse biological activities and pharmacological potential.”1Ashok Kumar Panda, et al. Traditional uses and medicinal potential of Cordyceps sinensis of Sikkim J Ayurveda Integr Med. 2011

It is worth noting that actual wild-harvested cordyceps are still prohibitively expensive. Unless you are extraordinarily wealthy you are unlikely to get your hands on “the real deal.”

Most of the supplements sold as cordyceps are actually lab-grown strains that are then made into an extract called CS-4.

It is unclear how effective CS-4 is in relation to naturally occurring cordyceps. However, most of the studies listed in this article use CS-4, so it is clear that this extract has a therapeutic benefit.

Where To Buy Cordyceps Mushroom

The Mushroom for Energy

Cordyceps Mushroom

  • Improve your stamina and energy levels

  • Helps improve your respiratory function and blood circulation

  • Potent anti-inflammatory and antioxidant effects

  • Helps ncrease the oxygen intake (VO2 max)

Cordyceps mushrooms are just one of the many natural options available for improving mental health. If you are looking for ways to reduce stress and anxiety or improve cognitive function, consider adding cordyceps mushrooms to your diet or supplement routine.

So, how do cordyceps mushrooms work for mental health and wellness?

These mushrooms contain compounds like cordycepin and polysaccharides which can help improve mental health by reducing stress and anxiety.

One of the main ways they do this is by helping to regulate the hormone cortisol. Cortisol is often referred to as the “stress hormone” as it is released when we are under stress.

Cordyceps also contains antioxidants that can protect the brain from damage caused by free radicals.

Studies show they can also help to improve cognitive function, memory, and focus while boosting energy levels. A recent study found that cordyceps improved memory and attention in a group of healthy adults. The study participants took either a placebo or cordyceps supplement for 12 weeks.

At the end of the study, those who had taken cordyceps showed significant improvements in memory and attention compared to those who took the placebo.


  • Available in capsules and powder form
  • Can protect against health problems like asthma, depression, diabetes, fatigue, high cholesterol, and upper respiratory tract infections.
  • Has been shown to improve athletic performance and reduce fatigue.
  • All-natural


  • Quality cordyceps can be quite expensive and hard to find

Cordyceps may have some potent nootropic benefits according to some researchers.

Cordyceps For Memory and Mood

Cordyceps may have the ability to boost mood and brainpower when taken as a nootropic supplement.

There have not been any human trials on the mental benefits of cordyceps, but there are some promising initial animal studies.

One team of researchers concluded that cordycepin, one of the active ingredients, “remarkably improved depression-like behavior” in rats.2Zhang Tianzhu, et al. Antidepressant-like effects of cordycepin in a mice model of chronic unpredictable mild stress Evid Based Complement Alternat Med. 2014

This lines up with anecdotes of cordyceps users experiencing a generally brightened, more energetic mood.

There are also multiple studies that have found memory improvements in rats that have been given cordyceps extract.3Guangxin Yuan, et al. Improvement of Learning and Memory Induced by Cordyceps Polypeptide Treatment and the Underlying Mechanism Evid Based Complement Alternat Med. 20184Zaixin Li, et al. Cordyceps militaris extract attenuates D-galactose-induced memory impairment in mice J Med Food. 20125Jungsook Cho, et al. NAntioxidant and memory enhancing effects of purple sweet potato anthocyanin and cordyceps mushroom extract Archives of Pharmacal Research. 2003

Anti-oxidant and Anti-inflammatory

There is also evidence that cordyceps has powerful antioxidant and anti-inflammatory effects.

Inflammation is an extremely important aspect of overall health. High levels can have far-reaching consequences for almost every system in the body.6Linlin Chen, et al. Inflammatory responses and inflammation-associated diseases in organs Oncotarget. 2018

Inflammation levels are largely a result of diet, pollution, and/or disease. However, some supplements, such as cordyceps, are proven to reduce some types of inflammation.

It appears that the compound cordycepin has some notable anti-inflammatory and anti-oxidant abilities.7Hardeep S. Tuli, et al. Pharmacological and therapeutic potential of Cordyceps with special reference to Cordycepin 3 Biotech. 2014

This means that cordyceps may have holistic benefits for a wide range of issues, including diabetes, heart disease, tumors, and auto-immune disorders (among others).

Cordyceps For Physical Performance

Cordyceps is famous in some cultures for boosting physical stamina and energy. It may be a useful performance enhancer for athletes, although the jury is still out on that.

One human trial saw an improvement in high-intensity training in people that took cordyceps.8Katie R. Hirsch, et al. Cordyceps militaris improves tolerance to high intensity exercise after acute and chronic supplementation J Diet Suppl. 2018

Another one found that older adults who supplemented with it had higher metabolism and ventilatory thresholds.9Steve Chen, et al. Effect of Cs-4 (Cordyceps sinensis) on exercise performance in healthy older subjects: a double-blind, placebo-controlled trial J Altern Complement Med. 2010

One study reported increased endurance for athletes that took a stack of cordyceps and Rhodiola another reported all-natural performance enhancer.10Chung-Yu Chen, et al. NRhodiola crenulata- and Cordyceps sinensis-Based Supplement Boosts Aerobic Exercise Performance after Short-Term High Altitude Training High Alt Med Biol. 2014

However, the evidence is far from conclusive on this subject. One trial concluded that cordyceps “has no effect on aerobic capacity or endurance exercise performance” on the trained male cyclists they were studying.11Allen C Parcell, et al. Cordyceps Sinensis (CordyMax Cs-4) supplementation does not improve endurance exercise performance Int J Sport Nutr Exerc Metab. 2004

So, more research is needed to determine if and how much this fungus could increase physical output.

Cordyceps For Libido

Sexual health (especially for men) is one of the major uses for this mushroom throughout history.

And fortunately, modern science is starting to confirm what many traditional healers have suspected all along.

Multiple human and animal trials point to cordyceps as a natural aphrodisiac. And it seems that both men and women can benefit from it.12Spandana Rajendra Kopalli, et al. Cordycepin, an Active Constituent of Nutrient Powerhouse and Potential Medicinal Mushroom Cordyceps militaris Linn., Ameliorates Age-Related Testicular Dysfunction in Rats Nutrients. 201913J S Zhu, et al. The scientific rediscovery of an ancient Chinese herbal medicine: Cordyceps sinensis: part I J Altern Complement Med. 1998

According to one meta-analysis, cordyceps can “can enhance libido and sexual performance, and can restore impaired reproductive functions, such as impotency or infertility, in both sexes.”14Kanitta Jiraungkoorskul, Wannee Jiraungkoorskul. Review of Naturopathy of Medical Mushroom, Ophiocordyceps Sinensis, in Sexual Dysfunction Pharmacogn Rev. 2016

These benefits seem to become more apparent in older populations, which obviously experience declining sexual desire, erections, testosterone, sperm count, and egg health as they age.

Anti-aging Benefits Of Cordyceps

But cordyceps not only preserves sexual health as you age. It also seems to have holistic properties that can slow the entire body’s aging process.

Multiple animal studies show that cordyceps’ antioxidant properties can delay some important genetic markers of aging.15Yiling Zhu, et al. Antioxidant and anti-aging activities of polysaccharides from Cordyceps cicadae Int J Biol Macromol. 202016Deng-Bo Ji, et al. Antiaging effect of Cordyceps sinensis extract Phytother Res. 2009

There is also evidence that cordyceps can prevent premature aging in human cells by scavenging free radicals, which can damage tissue.17Jun Myoung Park, et al. Cordyceps militaris Extract Protects Human Dermal Fibroblasts against Oxidative Stress-Induced Apoptosis and Premature Senescence Nutrients. 2014

Cordyceps For Diabetes

Cordyceps may be able to regulate blood sugar, making it a potentially valuable functional food for diabetics.

One trial found “significantly lower weight gain and higher blood glucose response” in diabetic rats that took cordyceps versus the control group.18Hui-Chen Lo. et al. The anti-hyperglycemic activity of the fruiting body of Cordyceps in diabetic rats induced by nicotinamide and streptozotocin Life Sci. 2004

How Cordyceps Mushroom Works In The Brain

Multiple rat studies suggest that cordyceps may increase testosterone production by regulating steroid and enzyme production.19Chih-Chao Hsu, et al. Regulatory mechanism of Cordyceps sinensis mycelium on mouse Leydig cell steroidogenesis FEBS Lett. 200320Chih Chao Hsu, et al. In vivo and in vitro stimulatory effects of Cordyceps sinensis on testosterone production in mouse Leydig cells Life Sci. 200321Yuan-Li Huang, et al. In vivo stimulatory effect of Cordyceps sinensis mycelium and its fractions on reproductive functions in male mouse Life Sci. 2004

In addition, this mushroom seems to be able to increase bloodflow to the nether regions. This can obviously help men get and maintain erections, but can also benefit women’s sexual health as well. 22W F Chiou, et al. Protein constituent contributes to the hypotensive and vasorelaxant activities of Cordyceps sinensis Life Sci. 200023Siegfried E Drewes, et al. Recent findings on natural products with erectile-dysfunction activity Phytochemistry. 2003

The unique organic compound cordycepin seems to be responsible for most of this mushrooms benefits

The organic compound cordycepin, only found in cordyceps, is thought to be responsible for its immune-boosting and anti-oxidant effects.24Xiaoxia Zhou, et al. Cordycepin is an immunoregulatory active ingredient of Cordyceps sinensis Am J Chin Med. 200825Y C Kuo, et al Cordyceps sinensis as an immunomodulatory agent Am J Chin Med. 199626Jovana D Vasiljevic, et al. Cordyceps sinensis: Genotoxic Potential in Human Peripheral Blood Cells and Antigenotoxic Properties Against Hydrogen Peroxide by Comet Assay Altern Ther Health Med. 2016

However, the precise mechanism of action is still unknown.

As far as increasing athletic ability, it seems that cordyceps works by upregulating “skeletal muscle metabolic regulators, angiogenesis, better glucose and lactate uptake” according to one animal study.27Rajesh Kumar, et al. Cordyceps sinensis promotes exercise endurance capacity of rats by activating skeletal muscle metabolic regulatorsJournal of Ethnopharmacology. 2011

How Much Cordyceps Mushroom Should I Take?

Cordyceps Mushroom Reddit Reviews

[su_quote cite=”u/SickkCunt” url=””]Having experienced my fair share of nootropics for the past 3 years, I can safely say cordyceps is definitely the most I’ve benefited from with absolutely no side effects at all. I tried most of the racetams, lion’s mane, ashwagandha, kratom, l-theanine, bacopa, uridine, phosphatidylserine, and probably a few others I forgot about. Many of the aforementioned nootropics particularly the racetams and ashwagandha caused sleep interruptions almost every time I took them so I had to ditch them. Lion’s mane was great as it drastically increased the vividness of my dreams in the most awesome way you could imagine (like high budget action movie shit), but didn’t notice any difference in my school performance whatsoever. My current stack only consists of cordyceps, guarana, and the ocassional kratom dose 2 or 3 times a week. I’ve been on this stack for 2 months now and acing my classes like it’s nothing. Not to mention cordyceps is AMAZING for sleep as I can sleep for 8 hours straight and feel like a million bucks. Last time I remember being able to sleep that long without any interruption was at the age of 16 and I’m 23 now. This stuff is gold![/su_quote][su_quote cite=”u/OptimusSpud” url=””]I’ll do an update later but yesterday I felt great. Not like a rush. Just aware, calm, collected and able to focus. Today however, I’ve been a bit of a shambles. And although I think cognitively I feel quite good, I seem unable to get my head around certain things. It’s quite frustrating. But this is also day 5 of being caffiene free. So perhaps it’s the last throws of that wearing off? I’ll stick at it.[/su_quote][su_quote cite=”u/OptimusSpud” url=””]After about 7 days I noticed more energy and more of a fluid train of thought with much less scatter brainedness.I’ve also started vivid dreaming which is nice. Albeit I wish they were lucid. [/su_quote]

[su_quote cite=”English Geek” url=””]When I heard about cordyceps, I was skeptical. My step father has late stage COPD and is a hospice patient. Just walking from the bedroom to the kitchen, his oxygen would drop down to 80, and his heartrate would jump to 120. Needless to say, he’s been bound to the hospital bed. So I figured I had nothing to lose. Since he started taking two capsules per day, his breathing is improving. Now when he walks to the kitchen and back, his oxygen sits at 97, heartrate 90. This is huge! His quality of life is improving, and he doesn’t use the nebulizer as often.A few weeks ago, I caught the flu, and I started taking it. Within three days, I felt much better.[/su_quote][su_quote cite=”Lee-Anne Woznak” url=””]I love these mushrooms! I got them to bring down the inflammation from my Lupus flare (which was so bad brought me to the doctor and got me diagnosed). Rather than take pharmaceuticals, I opted for a more natural approach, and thankfully, these products deliver! My achy painful body has calmed down, without having to deal with medication side effects! Thank you Real Mushrooms![/su_quote]
