Buying Guide – How To Choose The Best Low Sodium Protein Powders?

What Is Sodium

Sodium is an essential mineral. The body requires sodium to function normally. It’s one of the electrolyte minerals the body requires for fluid balance, nerve transmission, and muscular contraction. Table salt, or sodium chloride, is the most common form of sodium. The body needs sodium. Too much can lead to bloating, cardiovascular problems, kidney damage, and hypertension. 

How Much Sodium Should Be In Your Protein Powder

There’s no question that many people consume way too much sodium. One look at the labels of most processed foods and it’s easy to see why. The Dietary Guidelines for Americans recommends 2,300 mg of sodium per day for adults. If you have high blood pressure, you should be ingesting even less: 1500mg per day.  (1)

In terms of a packaged food, 140mg sodium per serving is considered low. Now think about how many protein powders contains between 200-400mg per serving. Every protein powder in this guide contains 65mg or less of sodium. Some powders are as low as 2mg. 

What You Should Look For In A Low Sodium Protein Powder 

A low sodium protein is one way you can begin to reduce your daily intake. Here are some things to look for in a low sodium protein powder: 

  • It Should Have 65mg Or Less Of Sodium – The lower the better, but you should go no higher than 65mg sodium per protein shake.
  • It Should Consist Of  High-Quality Ingredients – Your protein powder should have high-quality protein sources. It should also have a clean formula, meaning no artificial ingredients. In this guide, there are many choices with no more than 1-2 ingredients.
  • Flavoring – As noted above, the use of flavors doesn’t always increase the sodium content. You will find some flavored powders with less sodium than the unflavored versions. Muscle Feast Premium Protein is a good example of this. Naked Nutrition Naked Casein is an example of an unflavored version having less sodium than the flavored options.
  • Protein Quality – Always look for high-quality sources. This is true no matter what your reason is for buying a protein powder.

Why Protein Is Important

The body requires three macronutrients to maintain daily body functions. These are protein, carbohydrates, and fats. Every food you eat is a combination of each of these. 

Protein is the most important macronutrient. It provides 4 calories per gram. It’s important because the dry weight of your body is mainly protein. 

Amino acids are one of the components of protein. There are 20 common amino acids the body uses. These aminos can be organized into thousands of different sequences. All of these sequences control thousands of daily functions required by the human body.

Of these 20 aminos, 11 are made in the body. The remaining 9 must be provided by your diet and supplements. Protein must be ingested frequently. Your body needs protein daily. This means that protein must be consistently ingested during the day.

Your protein intake should consist of whole foods and quality low sodium protein powder. Protein is not an optional compound meant only for those that exercise or eat healthy. It’s critical for everyone, whether or not you eat right or exercise. (2, 3)

What Are The Benefits Of Protein

Here’s some of the benefits protein provides:

  • Supports Healthy Hair, Skin & Nails
  • Promotes Healthy Immune Function
  • Maintains Strong Bones & Teeth
  • Stimulates Protein Synthesis Which Triggers Muscle Growth
  • Enhances Recovery After A Workout
  • Helps Maintain An Anabolic Environment So Muscle Growth Can Occur
  • Supports Fat Loss
  • Prevents Catabolism – This Prevents Muscle Breakdown

What Are The Different Types Of Protein 

There are many different sources of protein that can be used for low sodium protein powder. Most supplement companies make whey, casein, and plant-based protein powders. Some companies make a whey and casein protein blend. Other products, such as Mutant Whey, consist of concentrate, hydrolyzed, and isolate.

Following are the most common types of protein used in low sodium powders:

Whey Concentrate – This is a very common type of whey protein. Whey concentrate is 80% protein with 20% consisting of fat and carbs. ProMix Nutrition Grass-Fed Whey Protein is a good example of high-quality whey concentrate.

Whey Isolate – This is the highest quality whey. It’s usually considered the best quality protein on the market. It will be low calorie with 90% protein content. 

Hydrolyzed Whey – This is whey isolate broken down into smaller particles for superior absorption. All whey proteins digest fast. Yet, this is the fastest digesting protein you can buy. Our guide features two products with hydrolyzed whey. One is Muscle Feast Hydrolyzed Whey Protein. The other is Mutant Pro. This is a specialized blend of three types of whey: concentrate, isolate and hydrolyzed. 

Micellar Casein – This is a milk protein that’s mainly known as slow-digesting protein. This can be used before bed or a long day at work. Micellar Casein is the highest quality casein protein. This is the protein used in our pick for best casein, Naked Nutrition Naked Casein.

Vegan Or Plant-Based – This can be a single vegan or plant source, or a blend of plant-based proteins. Common plant sources include brown rice or pea. There are also vegan sources such as sunflower and pumpkin. This guide features two Sprout Living Proteins using these two sources.

How To Use In A Low Sodium Protein Powder

Before using, make sure to read all the label information. You can mix low sodium protein powder with virtually any cold beverage. You can add it to your coffee as a high-protein coffee creamer. A low sodium powder can be mixed with oatmeal or yogurt. Some products, such as ProMix Nutrition Grass-Fed Whey Protein, are suggested for making homemade protein bars.

You can use a low sodium protein powder up to 3 times a day. This makes it easier to meet your protein requirements for the day. On training days, it’s important to consume one serving post-workout. This should be within 30 minutes after your training session is over. 

Finally, it’s important to drink a protein shake first thing in the morning. This is because you have been sleeping for as long as 7-10 hours. You will wake up in a catabolic state. For that reason, you should drink a protein shake. This will help you get back to an anabolic state.
