REVIEW: Muscle Milk Pro Series Protein Shakes

Flavor Tried: Intense Vanilla

Price: $8.99 for 4-pack ($2.25 per shake)

Nutrition: 170 Calories, 2g Fat, 8g Carbs (1g Sugar), 32g Protein

Whenever I have a long road trip ahead of me, I like to make sure I have protein shakes in the car. Otherwise, all I end up consuming is 100% carbs.

I could make my own shakes, but I love having ready-to-drink options at the ready. I’m not the biggest fan of protein shakes in general, so I tend to just buy whatever is on sale.

So, my most recent road trip led me to these Muscle Milk “Pro Series” protein shakes. I’ve had regular Muscle Milk protein shakes before (with less protein overall) so I wanted to give this higher protein version a try.

Overall thoughts on Muscle Milk Pro Series Protein Shakes

When you look at the nutrition facts, it looks surprisingly good for a protein shake.

The regular Muscle Milk protein shakes contain 160 calories and 25g of protein for the same size carton, so this is obviously a bit of an improvement on those.

The Pro Series also has a whole bunch of added vitamins & minerals compared to the original version, which is a nice little bonus.

Since I cut the ingredients list off, here is what this Pro Series protein shake contains:

Water, Milk Protein Isolate, Calcium Caseinate (Milk Derivative), Contains Less Than 2% Of Sodium Caseinate (Milk Derivative), Cocoa (Processed With Alkali), Soluble Corn Fiber, Natural And Artificial Flavor, High Oleic Sunflower Oil, Cellulose Gel, Inulin, Tripotassium Phosphate, Potassium Chloride, Potassium Phosphate, Sodium Polyphosphates, Cellulose Gum, Sucralose, Carrageenan, Acesulfame Potassium, Salt, Ascorbic Acid (Vitamin C), Sodium Citrate, Ferric Pyrophosphate, Calcium Phosphate, Vitamin E Acetate, Niacinamide, Zinc Oxide, Copper Gluconate, Calcium Pantothenate, Vitamin A Palmitate, Pyridoxine Hydrochloride (Vitamin B6), Vitamin D3, Thiamin Mononitrate (Vitamin B1), Riboflavin, Folic Acid, Potassium Iodide, Chromium Chloride, Biotin, Cyanocobalamin (Vitamin B12).

What is very interesting (and confusing) to me is how Muscle Milk advertises “contains no milk,” yet it contains milk protein. I guess it technically doesn’t contain milk, but that won’t help you if you’re vegan or have a dairy intolerance.

OK, but how do they taste?

Honestly, these Pro Series shakes were surprisingly bad. I can tolerate a bad protein shake because it’s a lot of protein to waste otherwise, but this is one of the worst-tasting pre-made shakes I’ve tried.

To be fair, I didn’t try these shakes refrigerated, so maybe that would change things slightly.

The vanilla flavor was pretty subtle, and there was an overpowering bitter flavor to it. Sipping it almost tasted like drinking spoiled milk.

Since the shake is so thin, almost like water, it saved that flavor from being repulsive. If it had been a thick shake that tasted spoiled, I’d probably have a hard time gulping it down.

On the flip side of that: do you really want a protein shake to be thin like water?

The shake leaves a slightly filmy feeling in your mouth, which seems to be standard for a lot of protein shakes out there. I reviewed Gatorade Zero with Protein, which gave that same filmy feeling, but that doesn’t happen with every product out there.

Muscle Milk Pro Series

On my road trip, I ended up suffering through these shakes and drinking them over the course of a long weekend, but I was less-than-thrilled about it.

I’ve had the original Muscle Milk shakes before and found them to be quite tasty, so these were definitely a let-down. I have to imagine that chocolate would be a better selection here, but in the future, I’ll definitely stick with regular Muscle Milk either way.

  1. I love the muscle milk slamming’ strawberry. 14 oz of delicious flavor and 40 Gram protein. To cheat a bit, I get these ice cold and pour half in a chilled glass , throw some Whip cream in, then fill with the other half and enjoy!!! I have also puréed some real strawberries and made slush. It’s a refreshing recovery after a good workout!!
