  • Simple, Effective, and a Must-Have for Lifting
Flavor Name: Unflavored - Capsules Size: 100 Count (Pack of 1)
I started my weightlifting journey about a year ago and added these creatine capsules to my routine about four months ago. The difference has been significant. I've noticed a clear improvement in my strength and performance during workouts since I started taking it consistently. I take the recommended serving of 5g daily (four capsules), and the capsule form is incredibly convenient—no messy powders or mixing required. It's easy to take with my other vitamins. I've been so impressed with the results that I've now added it to my monthly Subscribe & Save order. If you're looking for a straightforward and effective creatine supplement to support your training, I highly recommend this one. ... show more

  • Amazing!
Flavor Name: Unflavored - Capsules Size: 100 Count (Pack of 1)
Great value for the price and super effective for workouts. I’ve noticed improved recovery and endurance since adding this to my post-workout shakes. Mixes pretty easily with water or juice and doesn’t have any weird taste. A must-have for any strength training routine.

  • Convenient, effective, but not easy to swallow
Flavor Name: Unflavored - Capsules Size: 100 Count (Pack of 1)
I've been taking these creatine capsules for a while, and they’ve been pretty convenient. I used to use the powder version from the same brand — it worked great, but it was a real hassle to mix. I had to use warm water and stir it constantly just to get it to dissolve, and I even got a little scoop just to measure it out properly. The capsules are way more convenient in comparison. I usually take two before my workout. In terms of effects, I’d say it feels pretty much the same as the powder version. If you're new to creatine, don’t expect a dramatic boost like with a pre-workout — it’s more about steady strength support and helping with recovery. Creatine isn’t something that gives you an instant rush, but it’s definitely one of the most effective and safe supplements you can use long-term. The reason I gave it four stars is because the capsules are honestly huge. One time it actually got stuck in my throat and took a while to go down. Taking two at once is kind of a challenge, and considering you need multiple capsules a day to hit the usual 5g dose, it’s not a pleasant experience. ... show more

  • Convenient and Effective Supplementation
Flavor Name: Unflavored - Capsules Size: 300 Count (Pack of 1)
The Optimum Nutrition Micronized Creatine Capsules are a great addition to my supplement routine. These capsules appear to be the same powder in capsule form, which I really like for convenience. I initially considered creatine gummies but was concerned about their absorption compared to the powder. I still use creatine powder for my protein shakes, aiming for a total of 7.5g of creatine daily. However, dissolving powder in cold liquids was frustrating, especially for my morning dose. These capsules have solved that problem—I take two in the morning and then 5g of powder post-workout with my protein shake, making it simple and hassle-free. I’m planning to increase my intake to 10g daily once I’m confident it won’t cause any GI upset. Overall, these capsules are an excellent option for anyone looking to simplify their creatine supplementation without sacrificing effectiveness. ... show more

  • Best Capsule Option
Flavor Name: Unflavored - Capsules Size: 300 Count (Pack of 1)
Creatine powder disgusts me. I cannot drink it— it does not blend with anything. Water, juice, coffee, etc. It always has that gritty texture. It might be more cost effective, but only if you actually take it every day, which I did not. I switched to capsules in September 2024 and it has helped me stay consistent with my creatine intake. I’ve definitely felt results! My body looks pretty much the same but my strength gains have been noticeable— especially for my upper body strength as a woman. The pills are bit big, but if you shop around, the smaller pills from other brands need you to take 6+ pills per day (and they’re not even much smaller). In my opinion, these capsules are the best bang for your buck. Large but manageable in size, affordable options to buy in bulk, and third party tested. Good quality all around. ... show more

  • Premium.
Flavor Name: Unflavored - Capsules Size: 100 Count (Pack of 1)
These are amazing quality and have done so well for my stomach which I was very concerned about. No indigestion or discomfort. I already see a difference in my pain levels and focus. I work out and exercise but I didn’t get this creatine for those reasons in particular but they do help with my resilience and I can go longer and lift without getting tired easily. The difference in the issues with my back and the pains and cramps I was getting is fading quickly though and that’s exactly why I wanted to try these. Creatine really does have so many benefits and these are really worth the purchase. ... show more
