Written by Isaac

If you’ve found this article, then you know the catch-22 of protein shakes:

​Milk is too high in fat and carbs for cutting but most powders with water taste like chalk.

So we set out to find the best tasting protein powders with water so we didn’t have to force ourselves to down our morning shakes.

These five powders were without a doubt the best, and even we were surprised at how delicious they tasted.​

​...Now all those benefits are great. But what sometimes it’s left out is the all-important taste factor. It’s tough to keep downing protein shakes that make you want to gag.

​1. BSN SYNTHA-6 (Editor's Choice)

​Flavor: Chocolate Milkshake

If there’s one thing BSN gets right time and again, it’s flavor. And since we were looking for the best product, we turned to the chocolate milkshake flavor from their famous Cold Stone Creamery Series.

When both protein powder and water were combined, it was delicious.

The company claims it tastes like ice cream and mixes like a milkshake. We wouldn’t go that far, but for a shake without milk it was awesome.

Each scoop contains 22g of their ultra-premium “Syntha-6” and 10g of amino acids, so you get max muscle-building powder with the taste to match.

Honestly, it tasted so good that we actually looked forward to taking it post workout.

Part of us wishes it were lower in carbs because 15g is getting close to our limit per shake (though still under), but the mix of high-protein and great taste earns a spot here.


  • ​Cold Stone Creamery taste
  • ​High-protein/low-fat
  • ​10g of amino acids for better muscle building
  • check
    ​Hi-tech Syntha-6 protein


  • ​Great taste comes with a few extra carbs

​2. SFH Pure Whey Protein

Flavor: Chocolate

Next up is the cleanest entry on the list. If you’re looking for the best, leanest, healthiest powder, you can stop reading now. Pure Whey Protein from SFH lives up to its name.

The label is impressive to say the least. 24 grams of pure clean protein, only 130 calories, and only 2g of fat and 4g of carbs.

It’s great for anyone that wants to build muscle and limit everything else.

It’s 100% grass fed and contains no artificial anything. And since it’s so clean, it’s insanely easy for your body to absorb, which could lead to better long-term weight loss results.

If you’re anything like us, you struggle to stay within your macros.

Combining this protein powder mix with water provides a lot more breathing room without sacrificing taste even when mixed with water. Of course, this call comes at a price—it doesn’t taste as good as some of its competitors. That being said, it still tasted great.


  • ​Cleanest protein on the market
  • ​High-protein/VERY-low carb and fat
  • ​No artificial anything


  • ​Doesn’t taste as good as competitors

    ​Lack of carbs could decrease recovery

​3. Optimum Nutrition Gold Standard

Flavor: Double Rich Chocolate

For something so delicious, chocolate-flavored proteins have a nasty habit of tasting awful when not mixed with milk. With milk—amazing chocolate milkshake. Without milk—chalk and foam.

Optimum Nutrition has a great reputation around the fitness world for their great tasting flavors, so we went with their highest rated flavor for our taste test.

The double chocolate flavor was creamy, delicate, and, most importantly for us, easy on the stomach.

It went down really smooth and without any of that after taste you’re used to driving home from the gym with.

It’s also extremely lean—only 1g of fat and 3g of carbs (1g from sugar).

​As far as chocolate protein powder and water is concerned, this is about as good as chocolate gets.


  • ​Powerful chocolate taste
  • ​Extremely clean protein
  • ​Goes down smooth


  • ​Would be better without sugar
  • exclamation-triangle
    ​Double chocolate might be a bit much if not used to it

​4. Ultimate Nutrition Prostar

Flavor: Chocolate

Ultimate Nutrition is well known for their high-quality products at rock bottom prices, but their Prostar whey powder is their first foray into low-carb, all-around proteins for workouts.

They definitely kept up their best quality here, though it left a bit to be desired.

First, it packs a lot of protein (25g per serving) and is very low calorie, fat, and carb.

Second, it tastes pretty good. In fact, it tastes much better than it has any business tasting considering the price. 

Our first morning shake went down great and didn’t give us any of that overly full feeling during our workout.

However, there are a few things that show why it’s a bit cheaper than the competitors. It was a bit hard to mix (there were a few clumps), and it contains a few artificial flavors as well as soy.

It isn’t the best protein powder for water, but it’s a great choice if you need a healthy source of protein and you are on a tight budget.


  • Low in carbs, calories, and fat
  • Inexpensive
  • Mixes well with water


  • Contains soy, lactose
  • exclamation-triangle
    Contains artificial sweeteners

5. MuscleTech Phase 8 Protein Powder

Flavor: Milk Chocolate

If we had to choose one word to sum up this product, we would choose: BOOM.

Phase 8 is best known for their 8-hour multi-phase formula: the slow release of amino acids for 8 hours after consumption. In our opinion, this formula makes it one of the best proteins for post workouts.

Milk Chocolate is definitely our number one favorite flavor as we were surprised at how much we liked this one. The flavor when mixed with water smacks you straight in the face right off the bat.

It delivers a standard 26g of whey protein isolate with 5.6g of BCAAs and 5g of glutamine.

We’d recommend this to anyone who likes that creamy rich flavor.

Why Mix ​Protein with Water?

As much as we’d love to indulge on the best and delicious chocolate milkshakes all day, being serious about fitness means cutting the fluff and pumping your body full of as many clean, healthy nutrients as possible.

Mixing protein powder in water accomplishes two goals:

  • 1
    ​Your body absorbs proteins faster
  • 2
    ​It cuts unneeded calories, fats, and carbs out of your diet

​If you want to lose weight and gain lean muscle, you have very little nutritional wiggle room. When you mix whey powder with water, you are getting all of the good with none of the bad.

Milk vs Water: What’s the difference?

milk and water on the table

Aside from taste, the main difference between milk and water is the nutrient intake.

The best protein shake with milk will contain roughly 250 + calories, 10 + grams of fat, and 12 + grams of carbs.

If you mix it with water, you are looking at roughly 120-150 calories, 2g of fat, and very few carbs.

​On the flipside, drinking shake with milk provides your body more protein and more carbs, which is beneficial if you are trying to add mass. [1]

Verdict: Take protein with milk when bulking and with water when trying to lose weight.

​The Best Tasting Protein Powder with Water Is...

If we could drink shakes with milk all day and lose weight, we would. Instead, we are stuck with human bodies (and hope you are too or else this would be weird). The good news is you don’t have to sacrifice much taste at all. These products are by far the best tasting proteins to mix with water on the market.

However, if we had to choose a favorite, it would definitely be BSN SYNTHA-6 Protein Powder (Chocolate Milkshake Flavor).

The shakes were so delicious we forgot they didn’t have milk in them. It was the only product that made us look forward to our post-workout shake.

It isn’t the lowest calorie entry on the list, but this review is for the best protein powder, so that’s what we based it on. If you’re going for the best mix of great taste and healthy nutrition, this is without a doubt the best protein powder to mix with water.
