Taste good, Price has always been excellent, Simple Protein, Meal Replacement
I use this as a meal replacement maybe 3 times a week and it really helps. The nutritional value and protein quality are both excellent for the price as far as im aware.The ingredients are simple and not packed with junk, which I appreciate. The seal is always tight and fresh when it arrives. It mixes easily with milk or water, tastes good enough for a protein. If I mix a banana, oatmeal, a scoop and a half, and sometimes whatever else I'm feeling - Blend for a little and you can use anything to mix it, it'll taste great.

Mixes Well and Tastes Decent - Good Product!
I have used Optimum Nutrition's Whey protein for years and love the product. I wanted to add a Casein protein to my regimen (right before bedtime) so I naturally thought of ON first. However, after reading some of the reviews, I was very concerned about the comments regarding awful taste and poor mixing (clumping). Having used the product for about a week I can assure you that my experience with it has not reflected either of these concerns. I mix the product in a 28 oz Blender Bottle with 8 ounces of fat free milk and about 6 ounces of water. I add one level scoop of the ON casein and shake well for about 20-30 seconds. I then like to put it in the refrigerator for an hour or so before consuming. A couple of quick shakes when I take it out of the fridge and it's perfect. No clumps, not overly thick! The flavor is a bit sweeter than I would prefer but certainly not bad. I think mixing it with fat free milk rather than just water helps to smooth out the flavor (I find the same is true with the whey proteins). As noted above, I also use a bit more liquid than the instructions require (the package instructions say 10-12 ounces and I use about 14). I think this also takes away some of the overly sweet taste. I have not used the product long enough to give good feedback regarding the effectiveness. However, after the first week I do notice a bit faster muscular recovery after workouts. We'll see if that continues. The key - get a larger (28oz) Blender Bottle! Not one of the crappy substitutes, but the real thing. You can get them on Amazon for $8 - well worth it! For the Casein protein I find the larger (28oz) size works much better than the smaller (20oz) size.

Night Time Chocolate Protein Shake
I'm constantly tweaking my nutritional support and workouts to continue pushing forward, competing with previous and upcoming versions of myself and looking to keep improving wherever possible. I'd begun taking Casein protein initially as it seemed to make some sense to me in the conventional terms of keeping the body fed at all times; vs. Whey, this is a slower burning protein and is why it's most often used in the evening, taken before bed, where it will digest over several hours. When I've taken this, it's certainly eliminated the nighttime cravings to munch on food, minimizing the need to get out of bed at night hungry, while certainly providing a better and healthier option than some middle of the night snack. The formulations for casein proteins tends to be thicker and a bit smoother in consistency too, making it a great option for milk shakes, ice cream, and even brownies (video on my YouTube with personal recipe). It's not going to mix as quick and easy as whey protein, so always best to have a blender cup prefilled with milk or water (or combination of both) and add this last, before blending. If not, it will end up clumped on the sides and particularly on the bottom. The chocolate flavor is very tasty and filling. Lately, with an increased maniacal focus on ketogenic dieting, I've stepped back from night-time Casein consumption as actually became worried that I might be consuming *too much* protein, so have been experimenting with lower (.8-1.2 grams per pound of lean body mass) amounts, so will only take this on days when my macros for protein (and minimal carb cost) allow. I believe this helps me to sleep a little better too when I've taken it and continue to take notes, log every exercise and calorie in FitBit. It's wonderful to have so many sourced options for nutritional support and the ability to continuously experiment and figure out what works. Cheers!

Me encanta el sabor. Espesa bastante en bebida de almendras. Se disuelve mal, pero con batidora o espumador de leche queda perfecto.

First time I open the lid of an Option Nutrition product and didn't find a seal.

日本製とは違うと覚悟はしていましたが、普通に飲むこともできないくらい味が濃かったです。 普通サイズのシェーカーでは到底薄めることはできなかったです。 高タンパクだったので、期待したかったのに後悔しか残りません。

Would not recommend cookies and cream flavour, it’s filled with cookie chunks which don’t dissolve in water. It might be good if you incorporate it into your cooking eg some pastries, but you would be better off with chocolate/vanilla flavours if you just want a shake to mix with water/milk.
