X2PERFORMANCE Supplement Review

After my 10-mile run on Saturday afternoon, I am officially in taper mode. My Team in Training coaches have assured the group that your fitness level can’t improve in the two weeks before a race. Trying to push it during that time only increases the chance of injury. So, until April 27, I’m done with double-digit runs.


Since Saturday was my last chance to try a new fuel routine on a long run, I put my X2PERFORMANCE supplement to the test. I explained in this post that the supplement is meant to naturally increase energy, enhance endurance, and improve recovery. I was curious to see what effect it would have my long run. If it helped, I would plan to use it on race day. But it’s important to figure out your fuel routine before the big day.

I’ll admit that I was nervous about the instruction to consume the 2 oz bottle on an empty stomach 30 minutes before activity. I’m used to eating a snack around that time and didn’t want to entirely skip it. I compromised and ate a light snack one hour before my run, then drank the supplement 30 minutes before leaving. It didn’t taste as bad as I expected. I can be grossed out by anything that tastes like medicine, but the supplement has a very sweet citrus taste. I drank it with water, finished getting my gear together, and was ready to go.


Increased Energy – During the 30 minutes before my run, I kept trying to figure out whether I felt more energetic. I rarely drink coffee and never have energy drinks, so I was afraid I might get jittery. I didn’t feel more energetic until I started to run. Typically, the first three miles of my run are tough, and I find my rhythm by the fourth mile. This time, I felt energetic from the start and was still able to keep an even pace.

Enhanced Endurance – My energy level was consistent for the first eight miles. I kept my pace and was busy enjoying the sunshine and breeze coming off the Hudson. The last two miles were rough. I didn’t feel a crash in my energy, but my pace gradually slowed. I had to stop to stretch and grab another drink of water. I’ll have to try the supplement again to see whether the lack of endurance was a coincidence.

Improved Recovery – I’m writing this post a few hours after my run, and I feel great. After my first few 10-milers, I crashed when I got home. As soon as I ate, I needed a nap. Today, I don’t feel nearly as tired. I could use a good foam roll but otherwise feel like my energy has returned. I’m hoping this will mean that I’m not too sore tomorrow, so I can get in another intense workout in this beautiful weather.

Overall, I’m a fan of X2PERFORMANCE. I plan to test it out at least once more before deciding whether to use it on race day. I think the supplement would be worth taking just to start my race with more energy, as long as I don’t crash three-quarters of the way through. Have you ever tried a similar supplement?

    Nice review! You went a lot further on your run than I did on my trial! Good to hear that it sustained your energy for a long period. I agree that recovery was less crash-y than without.

    Do awesome in your race!

      Thank you! X2 definitely helped on my 10 mile run. I’m planning to try it on next week’s 8-miler before race day.

    That’s a nice overview of how X2 worked for the different aspects. Also a great idea to test it out one more time prior to the race. Good luck.

    Great thoughts! I like the idea of trying it a few times before race day. I found that I felt more energetic after the workouts as a result of using X2 as well.

    Glad to hear X2 helped! I am definitely finding it is helping on the recovery end – especially on days when I have back-to-back workouts.

    I agree with taking it on an empty stomach since I consume food 30 minutes before my training but I think it helped me overcome the need for food since X2performance has 60 calories. It may be mental for me :) great review!
