Why Choose Low Sodium Protein Powder?
For those who do not consume enough protein from food, nutritional supplements may be the solution. However, many protein supplements on the market are loaded with sodium.
Sodium is vital for normal bodily functions. It helps maintain nerve and muscle function and controls fluid volume in the body. However, maintaining a healthy balance is crucial for heart health and weight management.
This is where low sodium protein powder becomes invaluable, offering a healthy alternative without compromising health.
How Sodium Affects Heart Health
The average American consumes around 3,400 mg of sodium daily, and the average global intake is estimated to be around 10,800 mg daily! This is ridiculously more than most health organizations recommend.
Excess sodium can lead to many health issues and associated symptoms. However, the most common is hypertension (high blood pressure).
High blood pressure is a significant risk factor for heart attack, stroke, and heart failure. Consuming more sodium than your body needs contributes to heart disease by causing fluid retention. Pumping this excess fluid leads to added stress on your heart muscle.
A high sodium diet can lead to other health issues including:
Just because you don’t use a salt shaker does not mean you are following a low-sodium diet. Sodium is present in nearly every food from every food group.
According to the FDA, over 70% of Americans’ daily sodium intake is from processed, packaged, and restaurant foods.
Sodium Guidelines for Heart Patients
The American Heart Association recommends that most adults consume no more than 2,300 mg of sodium daily, with an ideal limit of 1,500 mg of sodium daily, especially for those with a history of heart issues or high blood pressure.
For those with heart disease, high blood pressure, or at higher risk of developing heart disease, keeping sodium intake within these guidelines may be challenging. However, it is essential to managing health and preventing complications.
Low Sodium Terms to Know When Reading Labels
Reading and understanding the lingo on nutrition labels is crucial to meeting daily sodium guidelines. The American Heart Association defines low-sodium options using the following label claims:
| If the Label Says… | It Means… |
|---|---|
| Salt/Sodium-Free | Less than 5 mg of sodium per serving |
| Very Low Sodium | 35 mg of sodium or less per serving |
| Low Sodium | 140 mg of sodium or less per serving |
| Reduced Sodium | At least 25% less sodium than the regular product |
| Light in Sodium or Lightly Salted | At least 50% less sodium than the regular product |
| No-Salt-Added or Unsalted | No salt is added during processing – but these products may not be salt/sodium-free unless stated |
According to the table above, a “low sodium” food claim means that the food contains 140 milligrams of sodium or less per serving, while labeling it as “very low sodium” means it contains 35 milligrams or less per serving.
When shopping for low-sodium protein powders, I recommend finding one with less than 140 milligrams of sodium per serving. Locating a protein powder with the “very low sodium” claim can be very difficult.
The “low sodium” claim is more attainable and can still fit within your daily sodium limit, assuming you are mindful of other foods in your diet that may contribute to overall sodium intake.
Do You Need Sodium-Free Protein Powder?
Heart patients can benefit from low sodium protein powder in several ways. For one, whey and soy protein supplementation may help reduce diastolic and systolic blood pressure. Soy protein may also help reduce LDL cholesterol and total cholesterol levels.
You may need a low-sodium or sodium-free protein powder if any of the following conditions or health goals apply:
- Severe high blood pressure, congestive heart failure, or other heart conditions
- Kidney disease or impaired kidney function– Follow the advice of your doctor or registered dietitian for protein intake.
- Post-surgery or recovery diets in general– Low sodium protein shakes can support healing without adding excess sodium to the diet.
- Weight loss and bloating– Choosing a low sodium protein powder can prevent water retention, leading to bloating and weight fluctuations.
- Overall sodium reduction goals– Protein powders often contain 200–400 mg per scoop, which adds up quickly when used daily.
Top Picks: Best Low Sodium Protein Powders for Heart Health
Now it’s time to get to business. Here are my top seven low sodium protein powder options. With all of these low sodium protein powder options being under 100 mg of sodium per serving, they can help you achieve your daily protein goals without jeopardizing your heart health. Enjoy!
1. Pure Food Plant Protein Powder with Probiotics*
Sodium Content Per Serving: 76 milligrams
This protein powder is vegan-friendly and contains three plant sources of protein (pea, brown rice, and hemp). The powder mixes well in liquids and has a mildly sweet, earthy taste, mainly due to the pure and clean ingredients used.
As the label states, there is NO sugar, NO fillers, and NO junk. This option is also low in carbohydrates and has zero added sugars, making it an excellent choice for those with diabetes.
Another unique feature of this low sodium protein powder is that it contains probiotics to support GI health. In other words, Pure Food Plant Protein Powder with Probiotics* is a low sodium protein powder that has a pleasant taste and won’t cause any GI bloating or distress.
The Pure Food company is also very charitable and will donate 5 meals to Feeding America for every sale they make! How cool is that?
2. NOW Sports Whey Protein Isolate*
Sodium Content Per Serving: 45 milligrams
This low sodium protein powder is very pure, containing only two ingredients– whey protein isolate and sunflower lecithin. It is an excellent option for most individuals as it is free of any artificial colors, flavors, or added sugars.
It also mixes easily in any liquid and is unflavored. According to online reviews, most consumers agree that the quality of this protein powder is superior to most. However, other consumers report one major con is the unpleasant taste.
Overall, NOW Sports Whey Protein Isolate* is a low sodium protein powder that is clean and contains minimal ingredients. But overall, it may be best to blend it with other foods (AKA in smoothie form) to mask the “baby formula-like” taste.
3. Muscle Feast Grass-Fed Whey Protein Isolate*
Sodium Content Per Serving: 41 milligrams
This option stands out as a low sodium whey protein powder that is also low in carbohydrates and added sugars. Muscle Feast did a great job keeping this protein powder low with only 41 milligrams of sodium per 24-gram serving.
It is sweetened with stevia, which I like. This whey protein isolate is another clean option with minimal ingredients and no artificial flavors or fillers.
There are several natural and delicious flavors to choose from, including:
- Vanilla
- Chocolate
- Cappuccino
- Unflavored (slightly more sodium- 43 milligrams per serving)
While I appreciate the simple formula, some reviewers do not feel this whey protein powder mixes as well as other options, and complaints are noted for being overly sweet (in flavored varieties) or having an aftertaste.
Considering everything, this is a good lower-calorie, low sodium protein powder. If you don’t mind the taste of stevia, then give Muscle Feast Grass-Fed Whey Protein Isolate* a try.
4. Up 2U Pronativ Native Whey Protein Isolate*
Sodium Content Per Serving: 20 milligrams
One unique feature of this low sodium protein powder is that it is sourced from fresh milk from a trusted network of U.S. dairy farmers. According to the company, their whey protein isolate is processed using a cold-filtration technique that boasts quick muscle-building with fewer servings and calories.
This option is also third-party tested for over 285 banned substances and contaminants. Additionally, it contains all nine (9) essential amino acids with a higher leucine content, making this an undeniable choice for muscle gains or weight loss.
Pronativ Native Whey Protein Powder* is lactose-free for better digestion, and has zero fillers, artificial ingredients, gums, rBST, or added colors. And if that wasn’t enough, it is also safe for those following gluten-free, vegetarian, or Kosher dietary restrictions.
There is little negativity to report back with this option, other than slight texture issues after mixing. One online reviewer felt it was like drinking “sand”. However, most others agree this is the best whey protein isolate on the market.
5. Genepro Plasma Treated Protein*
Sodium Content Per Serving: 20 milligrams
This low sodium protein powder is an appealing option for several reasons.
Like the Pronativ Native Whey Protein Powder, this option is just as versatile in terms of use. It’s unflavored, so you can easily mix it in sweet or savory recipes without changing the taste or texture.
It is also a super clean protein option with only one ingredient– whey protein isolate! According to the packaging, it is “plasma treated,” which reduces the protein molecule size and increases absorption. This means that an 11-gram serving is equivalent to 33 grams of protein.
Small serving size = Big protein benefits in this case.
Genepro 3rd Generation Plasma Treated Protein* is also suitable for a diverse number of health needs and conditions. Check out these other impressive facts about this low sodium protein powder:
- Low in calories
- Sugar-free
- High absorption rate
- Hormone-free
- Gluten-free
- Keto-friendly
- FODMAP friendly
- Contains milk, but is lactose-free
- Non-GMO
This may seem incredible however, there are still some online critics. Some complaints with this protein powder include poor dissolvability and an unpleasant taste despite it being “unflavored”. It appears that some of this brand’s loyal users feel that the formula isn’t what it used to be and they are now disappointed.
Overall, this one is an excellent choice for increasing protein intake without increasing calories- it’s only 44 calories per serving!
6. Manitoba Harvest Hemp Yeah! Organic Max Protein Powder*
Sodium Content Per Serving: 15 milligrams
Here’s a low sodium protein powder all-star! Hemp is not only a great protein source, it is also plant-based and carbon-neutral, making it environmentally friendly.
This option is made with only two ingredients: hemp protein concentrate and natural oregano extract. It is also unsweetened.
Some special features that set this protein powder apart from the rest are the omega-3 and 6 fatty acids from hemp and the high amount of potassium. One serving of Organic Hemp Yeah! Max Protein* contains 922 mg of potassium! This is a desirable nutrient to consume if your goal is optimal heart health.
While this option is pure, unadulterated hemp protein, the added oregano extract gets mixed reviews. The biggest complaint with this low sodium protein powder is the smell and taste. Some reviewers even go so far as to compare the flavor to “grass clippings” and say the oregano smell was “overwhelming”. While oregano tastes great in Mexican and Italian dishes, it may not be ideal to mix into a beverage.
If you give this one a try, I’d love to hear what you mix it with!
7. PB2 Pure Peanut Protein
Sodium Content Per Serving: 0 milligrams
If you’re looking for a low sodium protein powder option with minimal ingredients and the lowest sodium content, this one puts all others to shame! The only ingredient is roasted peanuts, and it is completely SODIUM-FREE!
I recommend the unadulterated peanut-only version. The PB2 brand sells peanut protein in other flavors like Dutch cocoa and Madagascar vanilla, though the sodium content is much higher.
If you choose this as your go-to protein powder, you’ll rest easy knowing it’s gluten-free, non-GMO Project Verified, free of added sugars or salt, and a great vegan option.
And since this is made from only peanuts, this low sodium protein powder has healthy fats and fiber to boot!
While this option doesn’t contain any sodium, it does have the highest amount of calories compared to all the other protein powders mentioned (200 calories per serving).
With that said, PB2 Performance Pure Peanut Protein may not be the best choice if you drink more than two protein shakes per day and weight loss is your goal.
