Mushroom supplement gains popularity among athletes
Cordyceps, a functional mushroom once overshadowed by its psychedelic cousins, has become a staple in Ireland’s wellness market. The fungus is now recognized for its reported benefits—energy, endurance, and respiratory support—without producing a high.
From ancient medicine to modern shelves
The change in perception took time. For years, mushrooms beyond the common button variety were dismissed due to their association with psychedelics. By 2025, attitudes had shifted. Cordyceps, in particular, became popular among athletes, biohackers, and health-conscious consumers.
Traditionally used in Chinese and Tibetan medicine, Cordyceps is a parasitic fungus that grows on insect larvae. Its wild form, Cordyceps sinensis, is rare and expensive, found only in high-altitude regions like Tibet and Nepal. The cultivated variety, Cordyceps militaris, is more widely available as a functional, natural supplement.
In Ireland, the mushroom is sold in health food stores, online retailers, and specialty supplement shops. It is marketed as a natural alternative to caffeine, providing sustained energy without the crash. Some users include it in pre-workout routines, while others use it for respiratory support, a benefit long documented in traditional medicine.
What the science says
Research is starting to support some of the ancient claims. Studies indicate Cordyceps may improve athletic performance by increasing ATP production, the molecule that fuels muscle contractions. A 2010 study in the Journal of Alternative and Complementary Medicine found that older adults who took Cordyceps supplements showed better exercise performance and oxygen consumption. Another study on trained cyclists reported improved endurance after three weeks of supplementation.
Respiratory health is another area where the mushroom shows potential. It may enhance oxygen uptake, which could help people with conditions like asthma or COPD. A study in Chinese Medicine noted better lung function in individuals with chronic bronchitis after taking Cordyceps.
Immune support is also a possible benefit. Like other functional mushrooms, Cordyceps contains polysaccharides and antioxidants that may help regulate immune function. Some research suggests it can increase white blood cell activity, aiding recovery from illness.
This trend mirrors the rise of other traditional remedies in fitness culture. Adaptogens like ashwagandha started as niche products before gaining wider acceptance as scientific evidence grew. Cordyceps differs because it offers both performance enhancement and respiratory benefits, a combination uncommon in natural supplements.
In Ireland, interest in natural health solutions has also grown. Lion’s mane mushroom is among the functional mushrooms gaining attention.
The market for functional mushrooms in Ireland continues to grow, though with some caution. While Cordyceps is generally safe, research remains limited. For now, it is seen as a supplement—not a cure—supported by centuries of use and increasing scientific interest.
Those exploring natural health options may also consider lycopene, which studies suggest could help cancer patients.
