I have specific health needs that require a high-protein, low-calorie diet, and this protein powder works perfectly as a breakfast meal replacement. I typically mix one scoop with 12 oz of 2% Fairlife milk and 8 oz of cold brew, which totals around 40 grams of protein. On its own, it provides 22 grams of protein per serving, making it easy to use multiple times a day to meet macro goals, even with just water. The flavor isn’t too sweet, and it adds a nice richness without a chalky texture. It also keeps me full from breakfast until my 1:00 PM lunch, even when I start my workday at 8:30 AM. For best results, I recommend using a good mixer bottle. My favorite is the Helimix 22 oz. That said, the powder dissolves well and doesn’t clump, making it easy to mix. Overall, this is a great choice for anyone looking to add quality protein to their diet without unnecessary calories or unpleasant textures.

There is a biological difference between casein-based and whey-based protein. I find that whey protein is less viscous when mixed with the same qty. of liquid than casein, so depending on your preference you might want to consider adding 1-2 more oz. of your liquid, otherwise it can be a little pastey, similar to the consistency of drinkable yogurts. Having purchased other brands before, I find the Optimum Nutrition brand line to be more favorable for casein products. The creamy vanilla flavor doesn't taste as chemically as other brands, but it is a bit more sweet than other brands I previously tried. I overcome this by using about 9 oz. of cold coffee with which to mix with the powder. The combination between creamy vanilla and coffee is a quite balanced flavor, and if you use caffeinated coffee you get an extra jolt. Recognize that casein is not intended (ideally) to be used right after a strength workout, b/c of the organic nature of how casein slowly enters your bloodstream. I prefer to use it in the morning when I wake up to supplement a very light breakfast, which helps keep the edge off until lunch.
