### ⭐⭐⭐⭐⭐ Great taste and works well to relieve pain
*by H***K on 28 April 2025*

I used this as a muscle pain reliever, worked almost immediately after first night use. It is very gelatenous when mixed in water or my preferred Milk. The powder does dissolve well and tastes great.

### ⭐⭐⭐⭐⭐ Nice taste, but thick texture. A bit difficult to dissolve for shakes but is brilliant to make protein pudding dessert!
*by G***3 on 20 June 2013*

My first attempt to make a protein shake with this Casein powder wasn't very successful, as it doesn't dissolve as well as whey protein, even with a shaker (I found that mixing it first in a bowl/glass with a small amount of liquid then adding more liquid is easier to dissolve it properly. I actually took advantage of the thick-high absorbing properties to use it to make protein pudding, with the following proportions: 20g of casein powder, 70ml of unsweetened almond milk (or other milk), 50g of fat-free yogurt, 3g of unsweetened cocoa powder, 5g of peanut butter, mix well and chill in the fridge for 30min at least, it will get smoother and thicken even more resulting in a delicious chocolate peanut butter mousse/pudding. It tastes like an indulgent dessert for only150kcal : 21g protein, 6g carbs of which 3g of sugar, 4g of fat (good unsaturated fat from the peanut butter). Being low in sugar, it's healthier than most desserts and it has also replaced my usual chocolate fix! I agree with another customer on a kind of "cappuccino"-like smell of the dry powder, but once dissolved the chocolate taste is nice. I have also tried the vanilla as a sample, which tastes like vanilla ice cream. Both are properly sweetened for most people taste I think, however I have cut my sugar consumption for the past two months and being more sensitive to any sweetness, I now find it a bit too sweet to my taste, but I will keep buying it anyway.
