Protein2o Review

Protein water is an alternative to protein shakes that you may come across on the supplement market. It is water infused with whey protein to still give you the benefit of a shake – without the heaviness that comes with this.

It does this by being less caloric and containing nothing but water and protein. There’s not many products on the market that offer this kind of benefit.

So, how well will it work for you?

In this review, we look closer at Protein2o protein water’s nutrition facts, ingredients, safety, and how it fares for both bodybuilders and keto enthusiasts.

Protein2o Ingredients

Ingredients: Water, Whey Protein Isolate (Milk), Natural Flavors (Coconut, Pineapple), Gum Arabic, Medium Chain Triglycerides, Sucralose, Calcium Citrate.

*For this review, we chose the Tropical Coconut Flavor.

Below, we look at the pros and cons of these ingredients and what you may have missed regarding Protein2o.


  1. Natural Flavors – Protein2O uses no artificial flavors which can give you that sweet, natural taste without the side effects. However it does contain artificial sweetener sucralose (more on that later).
  2. No carbs or fats – This product contains no carbs or fats which makes them easier for you to manage your macros.


1. Not Vegan

Using Whey Protein is not a good idea for several reasons, the primary being is because it isn’t vegan. In doing so, this restricts the amount of people who can use Protein2O.

Not only is Whey an animal product, but it’s also a dairy product which can cause issues for those who are lactose intolerant.

2. May Cause Side Effects

Another issue with Whey is the dairy itself. Whey protein used to be a great resource when supplements first came out – as there was no other option – but now it should be avoided when possible.

Because it comes from dairy, it needs to be heavily processed to be fit for human consumption, and even then it has been linked to gastrointestinal distress, general stomach upset and diarrhea.

It’s not a great option for Protein2o to choose, we hope they consider a healthier alternative like rice protein in the future.

3. Contains Sucralose

Sucralose, also known as Splenda is not a great addition to Protein2o Water.

It’s a zero-calorie artificial sweetener. Although deemed safe, sucralose may raise blood sugar and insulin levels if you’re not used to taking it.

With raised blood sugar and insulin levels your body can store fat much easier, which can cause issues if you’re trying to stay lean.

There’s also some animal studies which show sucralose to have a negative effect on your gut bacteria.

Protein2o Bodybuilding

Is Protein2o suitable for bodybuilders?

It can be to some degree if you’re looking to boost your overall protein levels while staying hydrated. Protein is good for boosting your muscle mass after a workout – however, there are better sources of protein than whey.

As we’ve mentioned vegan protein like brown rice protein are easier for your body to absorb and are also don’t cause any digestive issues like the dairy properties of whey do.

Protein2o can still help you need 15 g of protein in a pinch – but there are better alternatives.

Is Protein20 Keto?

Yes. Protein2o’s macros suggests that it is suitable for a ketogenic diet. It is zero carb and contains protein – not infringing on any allowances you have on a keto diet.

However, you should know that the sucralose can raise your blood sugar and insulin levels – which could pose problems for your ketosis if you’re looking to stay in a fat burning mode.

Protein2o Where to Buy?

Below are the following locations where Protein20 water is available:

  • Their official site (DrinkProtein2o)
  • Walmart
  • Target

  • Publix

And more. It is available nationwide in the US.

Protein 2o Summary

As you can see, Protein2o is a nice idea – but it may have a few problems which stop it from being one of the better quick protein options on the market.

First off, we really appreciate the convenience of the ability to get a protein boost from just drinking flavored water straight from the bottle. It’s easy, keeps you hydrated and there’s plenty of great flavors.

That said, you need to consider the fact that this product contains the artificial sweetener sucralose – which can raise your blood sugar if you’re not used to it which may risk a ketogenic diet.

Another problem is the fact that it uses whey protein rather than a vegan alternative. Whey is linked to causing gastric distress, stomach upset and other digestive issues.

We recommend:
Performance Lab Protein Stack

Performance Lab's Protein stack is the cleanest and most effective protein powder we've seen on the market.

Made with USDA organic brown rice protein and enhanced with probiotics, it is all natural vegan alternative which claims to be 30% faster to absorb than whey products.

It's low carb at 2 g of carbohydrates per serving, and high protein making it perfect for keto diets or for those who want more control of their macros.

If you're in the market for a better protein powder, you should definitely read what we had to say about it:

Protein2o Water

Protein2o has 15 g of protein, 0 g of carbs, 0 g of fat - and just 60 calories. But certain areas like relying on whey protein rather than pea or rice, and artificial sweetener sucralose let it down. It's good in a pinch - but not as a regular option.
