The Role Of Sodium In The Body

Sodium is an important mineral and electrolyte found in the food we eat, and the body needs salt for optimal health. The body needs about 500 milligrams of sodium to function properly to maintain fluid balance. conduct nerve impulses, contract and relax muscles, maintain the proper balance of water and minerals, and has a Recommended Dietary Amount (RDA) of less than 2,300 milligrams (mg) as part of a healthy eating pattern.

However, consuming too much sodium can negatively affect your health and cause problems like:

  • Fluid retention 
  • Weight gain 
  • Kidney diseases
  • Raised blood pressure
  • Higher risk of heart disease and stroke
What It SaysWhat It Means
Salt/Sodium-FreeLess than 5 mg of sodium per serving
Very Low Sodium35 mg of sodium or less per serving
Low Sodium140 mg of sodium or less per serving
Reduced SodiumAt least 25% less sodium than the regular product
Light in Sodium or Lightly SaltedAt least 50% less sodium than the regular product
No-Salt-Added or UnsaltedNo salt is added during processing – but these products may not be salt/sodium-free unless stated

To check the serving size and the number of servings you eat or drink to determine how much sodium you are consuming, always check the Nutrition Facts label for the food product’s sodium content. (Note that the nutrition information listed there is based on one serving)

Presence Of Sodium In Protein Powders

Most people drink protein shakes for many reasons like muscle gain, weight loss, and injury recovery. Daily protein intake creates a huge difference in your overall health, with the following health benefits:

  • Promotes growth and development 
  • Provides energy 
  • Carries oxygen throughout the body
  • Speeds up recovery from injuries 
  • Regulates hormones.
  • Builds muscle mass 
  • Reduces appetite and hunger levels 
  • Helps maintain a healthy weight 

But not all protein powders are created equal. Here’s why: 

The Truth About Sodium In Protein Powder Supplements

Sodium is a common ingredient in protein powder supplements. Some brands contain high amounts of sodium and most often assure quick and massive muscle growth. But in reality, high amounts of sodium can cause bloating and retain body fat, giving the illusion of gaining muscle mass

Others have ingredients that are naturally high in sodium. Pea protein powder supplements while being vegan, are often high in sodium, with products containing as much as 390 mg per serving, given the nature of their extraction process (the proteins are extracted through a salt solution). 

Supplements whose proteins are sourced from egg whites aren’t off the hook either. Egg whites also naturally contain a considerable amount of sodium, which does make its way into the protein powder, unless extracted mechanically or chemically.

Overall, opting for low-sodium protein powders and reducing the amount of sodium you consume may very well work wonders for your health.

Why Low Sodium Protein Powders Are Better

Low-sodium protein powder supplements are the best choice for anyone looking to increase muscle mass effectively without excess weight gain. It’s especially beneficial if you’re following a specific low-sodium diet. It can also help lower blood pressure, maintain cardiovascular health, and prevent fluid retention.

FAQs (Frequently Asked Questions)

What is low sodium protein powder?

Low-sodium protein powders are essentially protein powder supplements with a decreased amount of sodium. Sodium, an important chemical compound/electrolyte, is a common ingredient in protein powders; an excess of it can increase fluid retention and cause weight gain.

Why should I opt for low-sodium protein powder?

Choosing a low-sodium protein powder can help better meet your fitness goals and health needs since the decreased amount of sodium would not get in the way of muscle synthesis. It also offers a lesser risk of high blood pressure, heart problems, and kidney diseases.

Are there any health risks associated with low-sodium protein powder?

To date, there is no solid evidence that consuming low-sodium protein powder is harmful to bone, liver, or kidney health. However, individuals have been reported to experience bloating,  increased bowel movements, reduced appetite, or nausea after taking protein powders in excess. 

How does high sodium intake affect my health?

Consuming too much sodium can put you at an increased risk of high blood pressure, heart attack, and stroke, among other health problems. 

Can I use low-sodium protein powder for weight loss?

Yes. Opting for a high-quality protein powder that’s low on calories, carbs, sugar, lactose, and fat, paired with a healthy diet and exercise, can help you drop some pounds effectively.

What is the recommended daily sodium intake?

The Dietary Guidelines for Americans recommends a daily sodium intake of less than 2,300 mg — which is equal to about one (1) teaspoon of table salt.


  • Sodium is an important mineral and electrolyte found in the food we eat, and the body needs salt for optimal health, but consuming too much of it can cause health problems.
  • Sodium is a common ingredient in protein powders. While a mitigated amount is harmless, having a high sodium content may reverse the desired effect and result in fluid retention and unwanted weight gain. 
  • Low-sodium protein powders are an excellent choice for those who would want decreased amounts of sodium, either to avoid its side effects or if they’re opting to fast from it. 


When choosing a protein powder of your choice, consider a particular product’s nutritional label – how much protein it has, how high the sodium content is, or if it’s low on total sugars, carbs, calories, and fats. Choosing the best protein supplement helps you achieve your fitness goals and health needs better. 

Opting for low-sodium protein powders can make a huge, positive difference to your regular protein intake. You’ll be more set for optimal results, without the risks and side effects.
