Best Supplement for asthmatic
I have never noticed such a dramatic difference taking a supplement ever! Best thing I've bought before my latest half marathon I had a 13 minute PB! I've always struggled to improve my cardio because of my asthma but I've felt like I haven't even needed my inhaler lately, I see why someone called it their "third lung" I can't sing cordyceps praises enough, Thank you!

Simon L.5/5Verified
I Was apprehensive at first as to wether they were just placebo, but I was wrong and they have boosted my fitness levels nicely
William P.5/5Verified
Great Performance booster!
Was slightly dubious about testing these out to start with, however performance has improved along with VO2 max (up 2). Used for just over 1 month now and have bought more! Very pleased with this performance booster!

Excellent
Daniel W.5/5Verified
BP’s + beyond
Helps a lot with intervals and BP’s, always cheaper getting it via the subscription. The supplement is probably the best from what I’ve taken. It’s given me the results I’ve wanted, so always worth it coming up to marathons and races.
Séamus Q.5/5Verified
I actually need to work out what they are for, how they help with my performance

Have taken these consistently for a month whilst sticking to my running plan and my VO2 max has increased which is proof of the results this supplement can give.

Matt R.5/5Verified
For me, they're a must in a training block for any race. Increased energy, mood and performance.
Simon D.5/5Verified
Better than expected.
After 10 days I've started to feel some effects. While at high intensity intervals there is definitely a performance boost I haven't felt before. I run very consistently so I am quite in tune with my efforts. Another thing I have noticed which is a surprise is my sleep has improved. Backed up by my garmin which I've struggled with since having a child. Overall the product has gone over my expectations.
Kevin5/5Verified
Wasn't sure at first, but I must admit my stamina has picked up, I feel able to maintain a faster pace for longer. Now this could all be in my head, but whatever I have definitely seen benefits having taken these. I would also recommend taking them in the morning, the one time I took them in the afternoon I had a poor night's sleep???? I will buy again as I am training for Brighton next year
Paul B.5/5Verified
Life's better with Cordyceps!
I recently incorporated PureSport’s Cordyceps into my daily routine and am delighted with the results. PureSport’s commitment to excellence is evident with another outstanding product.
The Cordyceps provided a natural energy boost that enhanced my endurance without any jitters, allowing me to perform at my best throughout the day, especially evident in my running.
I've also experienced improved mental clarity and focus, which significantly boosted my productivity.
I highly recommend giving the Cordyceps a try for one month because without a doubt you'll be ordering more!

Vlada5/5Verified
great daily supplement
Great daily product backed by science, what's not to like
Kieran5/5Verified
Great product
Thought I would try these to see if they helped when I was running, I believe they did but only when I was consistent with taking them, when I wasn't consistent I'm not sure it had much effect, I believe this product is good quality, JUST BE CONSISTENT WITH IT.
Josh4/5Verified
Good product
I took one course of cordyceps and they seem to improve my endurance running performance and general resting heart rate. Only side note is that I took them when training for a marathon so it's difficult to judge how much was due to training and how much was the cordyceps
Stuart4/5Verified
Cordyceps for fitness improvement
I've recently started using the Puresport brand of Cordyceps. There is no after taste and I've not had any issues with digesting the tablets. I'm not yet sure if they have helped with improving my cardiovascular fitness but have done a before test and will do 'an after' test to check for this.

Great for marathon training blocks!
Felt like they made a massive difference through my marathon training block! Heart rate dropped considerably, which must have had an effect from these!
Jack5/5Verified
Great
Have bought this multiple times and while it's hard to put it down to these specifically, I do think it has helped my cardio in general. Will continue to buy
Helena5/5Verified
Noticeable improvement
Felt a noticeable difference in my cardio workout after a few weeks of supplementation. Would definitely recommend
Calum5/5Verified
My no.1 supplement
Taken cordyceps for about 6months and now wouldn’t be without so set up the subscription. Really noticed a difference in my fitness, training feels slightly easier since I’ve started taking these.
Alaine5/5Verified
Does what it says on the tin
After taking these for a few days I noticed a marked improvement in my CV capacity and general alertness. I wasn't needing a mid morning caffeine hit to stay awake. I also found that because I was needing less caffeine, my sleep was so much better. Overall, I would recommend not just for the performance benefit but the general life benefits

Why do I need Cordyceps?
Cordyceps is a functional mushroom used to boost cardiovascular capacity and endurance. Puresport's version is built specifically to improve VO2 max, support aerobic efficiency, and reduce fatigue.
How does it work?
Each serving delivers a 6:1 Cordyceps Sinensis extract (2000mg per 2-capsule serving), standardised for polysaccharides, mannitol, and adenosine — the compounds researchers link to Cordyceps' effects on oxygen utilisation and stamina.
When do I take it?
Since it's fat-free, water-soluble extract it doesn't need to be taken with a meal the way - most people take it in the morning or pre-workout since the endurance/fatigue benefits are most relevant during activity.
Why Puresport?
Cordyceps are Informed Sport Certified, high strength, rigorously tested, and organic.
