Fantastic product. I love using this is a capsule and not a powder. Capsule usage has fit into my routine better then trying to remember to mix a shaker on days I don't use preworkout.

Where is the measuring spoon?

Am I the only one still looking for the measuring spoon? I would at least expect some sort of measuring apparatus. I have different sizes of spoons. Do I really need to weight it every single use?

Does not dissolve and gritty

This is not the first time I have used a creatine product so I know what a good product mixes like. This does not dissolve even when using warm liquid and leaves a pile of sludge on the bottom of the glass. If I do physically mix it and take a sip it is gritty. There is so much waste at the bottom. I would like to return this product but we live an hour away so it will be awhile.

Review.

Easy to consume. I feel the powder works better for myself than previously consumed capsule or gummy products. As long as you are staying hydrated a phenomenal product. Powder mixes well into my water and dissolves with no problems. Will definitely be purchasing again and would recommend the product to anybody interested in a creatine product. One of the best for the price as well. Can't get much better.

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.

Not good

It tastes really bad. I normally can eat and drink things with no problem, but this stuff makes me gag every time. I wish I would've read the label more closely because this product is also full of artificial flavors and sweeteners. Skip this for a product with just creatine. This product also doesn't dissolve in water. It stays suspended for about 30 seconds before settling to the bottom of the cup.

The OG creatine

This works well for both me and my husband. We're active, healthy middle aged parents and we workout regularly but aren't gym rats. I've found (as a perimenopausal woman) the creatine helps me retain muscle, have more stamina during workouts. I usually put this in my coffee (I know not ideal, but it makes it so I remember to take it) and am intentional with water drinking. I did notice some water retention bloating after two weeks consistently using it which resolved in about a week. I think getting through the bloat phase and then staying consistent are key.

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!!
