Dopamine is a neurotransmitter that helps keep you motivated and focused on whatever task at hand.
It also plays an important role in your motivation, mental energy, and memory formation (which leads me nicely onto my next point).
Cordyceps mushroom is also known to increase ATP levels.
How the Cordyceps Mushroom boosts ATP levels
Adenosine triphosphate (ATP) works as the main energy source for our cells.
By increasing ATP, you can expect your brain's neurons to fire at a faster rate and make both short-term and long-term memory retrieval easier.
Cordyceps mushroom is also known to prevent free radicals from damaging our DNA, which can lead to serious diseases such as cancer.
By taking cordyceps mushroom supplements on a regular basis, you can help promote cell growth and regeneration by giving your body the energy it needs.
Now that I've taken a closer look at what the Cordyceps mushroom is and how it can help improve your brainpower, let's go over some basic facts about the supplement.
Cordyceps Dosage & Side Effects
Just like with any other herbal supplements you may be taking, cordyceps dosage depends on a number of factors such as age, gender, weight, etc., but most experts recommend around 1500mg per day.
It's also important to note that the cordyceps dosage will vary depending on what kind of supplement you are taking, so make sure you read through the label before purchasing!
As with any other herbal supplement, cordyceps can have some side effects for certain people.
Some of the most common side effects include nausea and headaches.
If you're experiencing these symptoms or anything else unusual while taking cordyceps mushroom supplements, please consult your doctor right away!
What are the benefits?
When it comes to benefits, it's hard to narrow down the list since cordyceps mushroom supplements can be used for so many different things.
That being said, here are just a few of its most popular uses:
When used as a Nootropic, cordyceps mushroom is known to promote better mental clarity, focus, and concentration.
It can also be used as a nootropic for those who suffer from ADHD or ADD since it helps to improve the brain's dopamine levels.
Can you take Cordyceps Mushroom and caffeine?
There is a lot of hype around cordyceps and caffeine, so I thought it would be important to mention that the two supplements do not work in the same way!
While both can help improve your mental focus and energy levels, they are actually quite different when it comes to the way they work.
Caffeine works by binding to receptors in the brain that are responsible for stimulating neurons, which can result in feelings of alertness and arousal throughout the day.
On the other hand, cordyceps mushroom is known to increase dopamine levels without affecting your heart rate or blood pressure.
So if you're looking to get a boost in energy without feeling jittery, cordyceps is the way forward!
If you've been struggling with fatigue and lack of motivation lately, or simply want to improve your cognitive abilities for better job performance and increased productivity - then it's time you gave Cordyceps mushroom supplements a try.
What I like about Cordyceps Mushrooms
I have personally used cordyceps and found it to be a great supplement for helping me feel less stressed.
I also find that I am able to focus more on my work without feeling fatigued at the end of the day!
I took 1000mg twice a day for about a month and felt much more motivated to get things done.
One thing I tried to experiment with was stacking it with caffeine.
I didn't really notice that much of a difference when stacking cordyceps mushroom with caffeine other than the fact that I felt a little jittery from the caffeine, which is why I would recommend cordyceps by itself when you're first starting out.
What I dislike about Cordyceps Mushrooms
The only thing I didn't like about cordyceps was the fact that it seemed to enhance the effects of caffeine.
I have a very low tolerance to caffeine in the first place, so I'm not sure if the jitters were just from that.
It was really hard for me to tell the difference between cordyceps and caffeine.
If you're thinking about stacking cordyceps mushroom with another Nootropic, I would highly suggest trying it out on its own first and seeing how you feel.
That way you can gauge the effects and work from there!
In Summary
The Cordyceps Mushroom is a very popular Nootropic.
It has been used in Traditional Chinese Medicine for hundreds of years and is known to boost energy levels, promote weight loss, combat stress/anxiety, improve focus/concentration and so much more!
If you're looking for a natural supplement that will give your brain the boost it needs without any of the harmful side effects, then Cordyceps mushroom is definitely for you.
The Cordyceps Mushroom works by increasing dopamine levels in the brain without affecting your heart rate or blood pressure.
It also helps boost ATP levels which can result in increased energy, stamina, and muscle strength.
The best part about cordyceps mushroom is that you don't have to take it every day!
You can simply use it as needed - whenever you are feeling stressed or fatigued, just pop some cordyceps into your mouth for an instant boost.
