Delivers a burst of energy and improved focus without jitters and without the typical post-workout crash. Infinergy™ DiCaffeine Malate optimizes energy levels, promotes mental focus, and stimulates thermogenesis.

Zire Preworkouts pack more of what’s needed and none of what’s not. That means no artificial sweeteners, no added sugar, no artificial dyes, and no unnecessary ingredients. Instead, it provides clean energy from a clean-label formula. Trademarked and patented ingredients work together to deliver pure forms of crash-free caffeine that are easily digested and absorbed.

I’ve tried a lot of preworkouts but I never found one that worked well for me. So I worked with our food scientists to create one. Most preworkouts do a number on my stomach and the energy would go to waste because the discomfort would interfere with my actual workout. Zire Preworkouts were made out of necessity.
And they’ve become the go-to for Spartan racers, marathon runners, power-lifters, Crossfitters, spinners, and more. We’ve received a whole lot of praise since we launched them. Quite honestly, I’m not surprised and I couldn’t agree more with everyone who’s given us their positive feedback.
Our in-house food scientists really hit the mark with our preworkout formula. It lives up to its claims of clean energy without the jitters and without the crash. I start my day with a scoop followed by a morning run then straight into a workout -- either high intensity or power-lifting but it depends on my mood.
On days that I’m intermittent fasting, preworkouts really hold me over since I have no fuel in my stomach. It gives me the push I need and helps me get into my moment. Not having to worry about stomach issues or crashing after a tough routine, I’m able to focus on my workout and on getting 1% better everyday.
I went on a trip and airport security took my preworkout powder. I had to order another one before I got back from my trip. They ship super fast so I already got it. I love this company!
Can't go a day without it.
I was using a different preworkout before until I found out it had a fake sweetener in it. I'm happy I found Zire Nutrition since they don't use fake sweeteners. Best of all, no sugar!
This is the first time I'm trying preworkout. It definitely helps with my workouts but I don't have much to compare it to. I like the energy. It feels clean.
Mixes well and tastes GREAT
