I recently "discovered" Met-Rx Protein Plus [I got the vanilla]. It's a metamyosyn protein blend with whey protein isolates.  I mix it in with regular skim milk.  It has a little aspertame in it as a sweetener, but you can hardly tell.  The stuff even tastes GOOD.  It tastes kind of like vanilla astronaut ice cream...

This morning I just mixed it in with my milk and it tasted like a milk shake.  Yesterday I threw it in the blender with 1/2 c of sliced strawberries and 1/2 a bananna.  It was REALLY good.

Wow, quite a flurry of answers huh? Ive never tried Muscle Milk myself, is it a powder mix? I can back up the recommendation for Optimum Nutrition, Ive used it for the last year... its great quality whey at a nice price (I get the 5lb jug for $20). Someone mentioned a fruit flavored protein... ON makes a "fruit punch" flavor of whey that can be mixed with water, although my experience with whey/water mixes has typically been less than spectacular.

ON, about 23.00 for 5 pounds.

I believe that natural forms of protein are still the best but because of the low quantities of protein in most foods, I find it becomes necessary to supplement your diet with extra protein.  I do not believe it is necessary to pay allot of money for expensive designer protein.  Check the protein for the number of serving per package, as many claim to provide higher amount of protein but only because you have to use more of the product.  I am sure I will get emails from protein manufactures but I do not think one protein is any better than another.  Make sure you follow the simple role of ensuring that your body is getting a minimum 1 gram of protein per pound of body weight.  Good Luck
