Performance Nutrition

Creatine is one of the most popular sports nutrition supplements in the world, having been shown to support muscle gain, strength, endurance, and anaerobic performance for the last 25 years.†

Creatine works by aiding in the regeneration of ATP, the fuel source for muscle contractions. As a result, it can help you get more reps on weight training exercises, and sustain short burst anaerobic activities — such as sprinting, jumping, and martial arts training — with greater power for longer durations.†

What is Creatine?

(And Creatine Monohydrate)

Creatine is a molecule produced naturally in the body. It's also available in foods such as meat, fish, and eggs. Creatine monohydrate (in micronized form, provided by Creapure®) is one of the most widely used and studied sports nutrition supplements for more than 25 years. Recognized as safe and effective, creatine monohydrate helps supply energy to the muscles to train harder. It has long been trusted by gym goers and bodybuilders who want to gain muscle weight because it allows you to get more reps on sets of strength training, thereby increasing the stimulus to your muscles.†

Power athletes such as sprinters, volleyball players, and wrestlers use creatine to increase their explosivity and ability to repeat bouts of high intensity activity. While it undoubtedly enhances performance, creatine is not banned in any college or professional sports.†

A meta-analysis of 100 studies found that creatine supplementation improved body composition and resistance exercise performance, regardless of the subjects’ gender or training experience. Another massive review (22 studies) published in the Journal of Strength and Conditioning Research discovered that the average increase in muscle strength for subjects taking creatine while strength training was 8% greater than gains made on placebo. Looking deeper, the average increase in reps performed at a given percentage of the lifters’ maxes was 14% for those taking creatine. Bench press strength in particular went up—by as much as 43% for one-rep maxes.†

Most sports have anaerobic energy demands. They require you to go hard for a short duration, recover quickly, and go again. If you participate in these kinds of activities, either recreationally or at a high level of competition, creatine can help keep your gas tank topped off. A study on elite wrestlers found that creatine enhanced their average and peak power on an anaerobic endurance test. Another trial in 2014 on elite soccer players showed that those on creatine sustained jumping power during workouts while the placebo group saw its performance trail off. Finally, a similar study on collegiate volleyball players revealed that creatine improved repeated block jump height without creating any more fatigue in the leg muscles.†

Success is inevitable with solid nutrition

When you put in the work and pay attention to the details, seeing the results you want becomes not a question of if but when. It's just a waiting game. Because when your foundation is strong, adversity doesn't shake it—it merely becomes more brick and mortar to build with. Creatine is a cornerstone in a strength athlete's supplementation, providing the energy to take your workout farther into places that produce gains.†

The Evidence is Overwhelming

Creatine can help you become stronger, more explosive, and even look better — all while being safe for your body and for competition.†

Rated 5 out of 5 by from Perfect for any workout I just started getting back into a 4-5 day workout routine. After 4-6 weeks I'm starting to notice a difference in my physique and energy output.

Rated 5 out of 5 by from Gains Creapure Ceritfied Creatine. I started a new routine and hit the gym with this being my only supplement. I have been really suprised at the results I've seen in just the first 6 weeks. I am sure the change in routine helped, but I have started many new routines and never have I seen gains like I have recently.

Rated 5 out of 5 by from Very smooth This is only the third brand of creatine I’ve used so far and it’s now the only brand I’ll use. They’ve all been creatine monohydrate, some were ‘micronized’, all up to now have been almost impossible to mix and ended up gritty and sandy and stuck in my teeth. Onnit’s creatine mixes up almost as well as a high quality whey, without using a mixer.

Rated 5 out of 5 by from Fantastic! I’m about a month in and this definitely works! I noticed the difference almost immediately I’ve got more endurance and deep into sets I’m noticeably stronger. Mixed with a protein powder and I’m up 15lbs already which is impressive to me given I’m a hard gainer. I will continue with to purchase this product

Rated 5 out of 5 by from Beyond Satisfied! Just ordered my second container and am very happy with this product. No BS and it did not upset my stomach like some creatines. If you plan on loading order two off the bat!

Rated 5 out of 5 by from Works really well! I'm on my second can of the onnit creatine. I got it mainly for the cognitive benefits (I absolutely notice a difference there, which is great.), But I'm definitely much bigger as well. My muscles feel more full and stronger. I feel like I can contract them better than ever. It's great! I've set up an auto order.

Rated 5 out of 5 by from Great Creatine I love Onnit products because you know you are getting the value out of every product you buy. You know there isn’t a bunch of random added ingredients like most other companies. This creatine has significantly helped with my strength and muscle development. Thanks Aubrey Marcus and Team!!

Rated 5 out of 5 by from Onnit hit a home run with this one I’ve been using Onnit’s creatine for about a month now, and I love it. I’ve added at least 5 more reps to most of lifting. just need to stay hydrated while using it. Keep the good products coming Onnit!
Date published: 2018-12-08
Rated 5 out of 5 by from Great product, only one minor thought You only get enough per container to come up to the "Proves Strength + Performance" label. (about 25% full) Big container for so little. Im not sure if it goes bad quickly, but either give us more or smaller container? Supps are probably one of the highest margin products in history. For 30 bucks, c'mon....

Rated 5 out of 5 by from Great Creatine option Been using it for a month now and have added a few pounds of lean muscle. Good creatine for the price. Also tub does seem on the light side but I got my full servings and scoop!

Rated 5 out of 5 by from GAINS First of all very happy that Onnit sells creatine! Okay so after using this for about two weeks i can totally feel a difference i mix with my pre-workout and it helps give it a big boost. My endurance has gone up while using it i would highly recommend it for anyone who works out .

Rated 4 out of 5 by from Amazing price with better results. Having used Store Brand/Name Brand Creatine for years I finally caved in and bought this. It has been a wonderful experience. Pros: The product arrived undamaged/Clean Shipped and delivered on time Mixes well and dissolves very well! Little to no discernible taste "Feels" cleaner going in. Cons: I was really let down when I opened my tub and it was only half full. Every other supplement I buy come FILLED, not HALF full, all the way full. That I will keep ordering this and getting half filled tubs but I cant stop now, this stuffs too good. lol
Date published: 2019-03-22
Rated 4 out of 5 by from Doesn't dissolve?? I'm on my 3rd jug and I have made some gains, but I am wondering if I am getting all of the creatine absorbed into my body. The searching I have done says creatine will fully dissolve in water, but this product does not.
Date published: 2019-03-20
Rated 4 out of 5 by from Does it’s JOB! It definitely does what it’s supposed to do. For me it really made me eat more than I normally eat and you definitely notice a difference in your strength and increase in reps. I’m satisfied with it. Plus, the tasteless powder is great!

Rated 3 out of 5 by from Gritty This creatine is a bit gritty compared to other brands I've tried; doesn't mix well in water in a blender bottle. Also, I ordered three containers, when they arrived, I put the contents of all three into one to save counter space. (the containers are basically one third full!)
Date published: 2019-12-27
Rated 3 out of 5 by from Container basically empty when I opened it. Opened the container ready to dive in for the scoop only to find that it was less than half full. Maybe I missed something in the description when I purchased but this is the first time I’ve ever seen such little product per size of packaging. Other than that it’s a great choice for high intensity workouts. Only creatine I’ve ever taken that was truly flavorless.

Rated 3 out of 5 by from Creatine I’ve bought this a couple of time already. Quality is great, but expensive for the quantity

Rated 3 out of 5 by from Good product but hardly any in the container I just bought my first batch of Onnit creatine, stoked to start getting jacked. Well, I opened the container up (which is pretty small itself) and the actual product fills less than a third of the container. This was a big disappointment, I got a good deal but feel like I didn't after opening it up. We'll see if it actually lasts 30 days.
Date published: 2018-07-30
Rated 2 out of 5 by from Does not dissolve Possibly a bad batch or is it normal for it not to dissolve? After following the directions and shaking, letting it rest, re shake, adding more water, shaking some more. This stuff does not dissolve whatsoever.

Rated 1 out of 5 by from Container not full Will not purchase this again as the container was 3/4 empty.

Rated 1 out of 5 by from Sludge It does not dissolve in water. I have been using it for 2 weeks and in order to get full serving, I have to spin the water in the my container and drink it quickly. Even when I do this, there is a sludge at the bottom and on the sides of my water jug.
