Low sodium protein powders are key if you’re watching your sodium intake, and still looking for a top protein powder to optimize your fitness. And consumers spend a great deal of money on protein powders that promise to make them feel healthier, lose weight, and add muscle. Little do they know that many times they’re unwittingly adding something unwanted to their body as they chase better fitness – excess sodium.

Research shows that out of the 81 protein powders tested, 70 of them contained a higher amount of sodium content than the nutritional facts identify. (1)

But why so much sodium content?

Many of these protein powders promise solid muscle growth. But some have high amounts of sodium. Excess sodium causes bloating, which tricks consumers into believing they’ve added muscle mass when they weigh themselves.

In this article, we’ll highlight the best low-sodium protein powders you can use, without worrying about the risks of high sodium.

Read on to learn more.

How to Choose the Best Low Sodium Protein Powder

Before we jump to our top low-sodium protein powder list, here are some of the attributes to look out for. After all, if you go ahead and buy a low-sodium protein powder that falls short on these factors, you’ll be doing yourself a disservice.

  • Cost-benefit analysis: Because prices on different brands vary, it’s best to check which brand offers the best value. So focus on the cost per flavor and serving because these are the most significant determining factors on whether you’ll get the satisfaction you need. And always prioritize value, not price. 
  • Sugar content: You should remain mindful of a protein powder’s sugar content, especially if you’re trying to lose weight or are diabetic. A few grams of sugar make a difference.
  • Organic vs. non-organic: There’s an endless debate on the value of organic food vs conventional options. We suggest that if you desire organic products, you ensure they meet the designated standards because organic labels can be misleading.
  • Protein value: You’re buying a protein powder because of its protein content. So, the higher the protein content per serving, the more you get for your dollar. Even more, not all protein types are equal, so check the protein type in your chosen powder.
  • Sodium: You can find protein powders that contain no sodium or a minimal amount, which may vary between 10mg and 60mg. So, take into account your preferences. The FDA recommends 140 mg per serving and below. The different sodium types are sodium benzoate, sodium chloride, and monosodium glutamate. (2)
  • Taste and flavor: While this may or may not be a huge factor for you, consider it a bonus if you like your protein powder with a bit of flavor. Some protein powders have a chalky taste, so just keep this one in mind as you assess the list.

Now that you know what to look for when shopping for your low-sodium protein powder, let’s look into the best low-sodium protein powders in the market.

Crazy Nutrition Salted Caramel FlavourCrazy Nutrition’s 100% TRI-PROTEIN is a protein supplement that supports muscle recovery, burning fat, performance, and muscle growth. Its formula offers the body’s correct amount of protein for muscle development.

Furthermore, 100% TRI-PROTEIN contains six different protein sources released in three phases (hence the “TRI”). At each phase, proteins are broken down to aid in muscle growth, strength, and energy. The protein suits athletes and bodybuilders for lean muscle mass, better recovery, and gaining more strength.

  • Sodium: 0.19g per 30g serving

It gives your body more strength and energy than the regular soy, hemp, and other whey protein formulas.

Three-phased Release

TRI-PROTEIN has a 3-phased release mechanism, so the protein is “dripped” over 24 hours. So your muscles are sustained and fed protein in a phased release, as opposed to one dose and done.

2. Optimum Nutrition Gold Standard 100% Casein

Gold Standard 100% Casein - 8 Low-Carb Protein Powders for Healthy Muscle BuildingRapid protein usage is necessary before and after exercise to help refuel your recovering muscles, but sometimes delayed digestion and absorption are also beneficial. Because casein proteins are acid-sensitive, they tend to thicken in the stomach.

Thus, it takes twice as long for the Gold Standard 100% Casein to break down.

The powder is excellent for muscle support as you sleep and after a workout. It delivers 24g of slow-digesting casein per scoop.

Product Specification

Another standout feature is its low-carb/sugar content making it an excellent option for individuals on a ketogenic diet. Also, the Gold Standard 100% Casein is an excellent source of protein for lactose intolerant people.

MyProtein Impact Whey Protein - 8 Low Sodium Protein PowdersExcellent for muscle support post-workout and during sleep. This faster-digesting, low-sodium protein provides a range of essential and non-essential amino acids that stimulate growth and recovery.

  • 1g fat

Product Features and Benefits

This protein powder is quite well-known among athletes for being an affordable, high-quality protein. It wins our top pick in price, though it falls behind in macronutrient breakdown.

The main problem is a relatively high content of carbs and sugar. It may be fine for those on bulking or maintenance, but it may cause some difficulties for athletes who count every gram of carbs in their diet.

Still, it’s excellent in terms of its quality. The brand uses only natural ingredients; a great match if you are searching for protein with no extra additives but also like good deals.

In addition, grass-fed whey contains high immune boosters like lysozyme, lactoferrin, and beta-lactoglobulin. The compounds improve the body’s response to fight against infections. (4)

In addition to boosting immunity, the conjugated linoleic acid (CLA) helps preserve a lean muscle mass and enables you to burn more fat. Also, both CLA and omega-3 fatty acids support a better metabolism while improving your cardiovascular health.


It’ll cost you $94.99 for a 5lb tab. You don’t expect to buy first-class protein powder cheaply. It costs a little more if you wish to enjoy first-class quality.



7. Nutiva Organic Hemp Seed Protein Powder

Nutiva - 8 Low Sodium Protein PowdersThis protein powder has organic whole raw hemp seeds with the oil expeller pressed. The process extracts 80% of the oil content from the seeds. 

Nutiva isn’t very tasty because it contains only one gram of sugar and is sodium-free. But you’ll love that it blends well with juices and other shakes.

Product Specification

  • 1 g of sugar
  • 3 g fat
  • 15 g protein 
  • 110 calories 
  • Sodium 0mg

Product Features and Benefits

Nutiva is among the best options for a no-sodium protein powder in this list. It is an organic plant-based supplement, which is, on top of that, relatively affordable among other vegan products.

The most exciting part about this protein is the source of it – hemp. It is pretty unpopular on the market but has some valuable benefits. In our case, Nutiva contains no sodium, so it may be a perfect match for athletes with some health issues forcing them to decrease their salt intake.

On the other hand, people who are searching for the highest protein content better skip this option. The serving size is 30 grams, but only 15 are protein. That is, unfortunately, the biggest drawback of most vegan supplements. On the other hand, if you want to increase your protein intake, even 15 grams of it make sense.

Another benefit of Nutiva is the absence of lactose. Athletes with stomach issues may not tolerate whey proteins well, but plant-based options can be a great solution.


A peak protein 16 oz tab costs approximately $20.99. The different flavors and options have different prices. Also, you can save more through the discounts they offer when you buy in bulk or have a subscription.



Benefits of Low-Sodium Protein Powder

Excess sodium intake primarily hinders the cardiovascular system, which is harmful to the kidneys, and may make you look plumper than you are. Here are some of the benefits to expect in taking low-sodium protein powders.

1. Keeps Blood Pressure in Check

Your blood pressure is the most severely affected when taking too much sodium. It may spike your blood pressure, leading to numerous heart conditions such as stroke in the long term. Thus, most people prefer to stick to low-sodium protein powders.

2. Bloating

You might experience bloating and other gastrointestinal issues with increased salt intake. So, switching to a low-sodium protein powder is advisable.

3. Swelling

Your level of swelling depends on your sodium intake, which controls fluid balance in the body. If you notice that the face looks plump, it could be a sign of too much sodium intake. It’s high time you switch to low-sodium protein powders.

The Bottom Line

Sodium intake is just as critical as healthy fats, proteins, and carbs intake, and curbing sodium intake is as crucial as curbing sugar intake.

To sum up, the eight protein powders we’ve reviewed are some of the best low-sodium options on the market. They’ll help you stick to your low-sodium diet and help you with muscle building, weight loss, and general well-being.

Remember, these protein powders only supplement a healthy diet and lifestyle. They’re a supplement to whole foods to help you reach your fitness and health goals.
