Verified Purchase

Excellent

Product does not include teaspoon. I understand environmental awareness but it could be a different material design (biodegradable) and always offer this to customers.

As part of ON's effort to be environmentally conscious and reduce plastic, our Creatine Powder does not come with a scoop. The serving size for this product is one rounded teaspoon. We've shared your feedback for biodegradable options with our internal teams!

Yet another subscription

Before Creatine: I was strong. After Creatine: I was stupid strong. My deadlift spiked 70lbs to almost 5 plates within a month of getting on the goods. I am a believer and hooked. Ok, it wasn't just some magic powder that is probably on some banned list. But I was able to noticable go harder at everything in the gym and in the mountains. It certainly paid off in areas like gym lifting where it is easier to get measurable results. I guess this will now be like my iCloud and Spotify subscriptions – paying for life!

Just Right

Creatine is a critical part of my nutrition and training. I take it everyday and being about to buy in bulk is essential. Optimum Nutrition is a brand I trust and this product doesn't disappoints. It's a brand I trust and continue to come back to time and time again. I think the mouth of the container could be wider to make accessing the powder easier. If you're new to creatine or an experienced user this hits the spot.

No scooper

Does not come with a scooper. Wants to to carry around a spoon with you. Hope they saved a lot of money not including one. Will not buy again.

Better brands available

Creatine does not mix at all and is very gritty. Other brands at least mix a little bit. This container does not come with a scoop either.

Pull this from the shelves Sam…

This stuff is absolute garbage. Crystals the size of sugar that doesn’t dissolve. Terrible bloating feeling after drinking. By far the worst I have ever bought.

Creatine is a product that does not fully dissolve, so rest assured that this is completely normal. Note that creatine should be consumed immediately upon mixing.

Good from what I can tell

Started taking these a little over a month ago and noticed a slight difference in my workouts about 3 weeks in. It seemed to be most helpful on my bench reps specifically, but I am hoping it is benefiting my recovery as well as I was struggling with soreness. My training is a little dialed back currently but I am less sore and seem to be able to do a few extra reps in the gym. Only being able to order from them once every 90 days means I will need to find another source for my next batch which is annoying.

Prefer the pills over powder

Like almost all perimenopausal women, I’m concerned about sarcopenia, brain fog and have been taking creatine. First I used powder in my breakfast smoothie but then got tired of only ever having a smoothie for breakfast. Then I put in my coffee, but I could taste it and missed actually enjoying my coffee. The gummies are too expensive and extra sugar, so these capsules fit the bill well. Easy to take, no weird after taste. Will continue to use them.

New add to my daily supplements

Optimum Nutrition Micronized Creatine has become a permanent part of my daily supplement routine. I really appreciate that it contains no dyes, no unnecessary additives, and absolutely no flavor, which makes it incredibly easy to mix into anything. It dissolves smoothly and doesn’t leave any gritty texture behind, even when added to coffee. Because it’s completely tasteless, it never alters the flavor of my drinks, which is a huge plus compared to other creatine powders I’ve tried. I’ve noticed consistent performance and recovery benefits, and I love how simple and clean the formula is. If you’re looking for a reliable, no-frills creatine that fits seamlessly into your routine, this one is hard to beat.

Does Exactly What it Should

I love that I don't have to worry about getting powder all over the place. The capsules make it easy to take and be consistent with. That ease of use worked well for me. I keep it in the car so I can take it in the morning on my way to work. Creatine is not just for athletes and it has incredible benefits for cognitive function. A great supplement to take in my opinion and from a great brand too!!
