Protein Powder for High Blood Pressure

Can Protein Powder Cause High Blood Pressure?

As you probably already know, excessive sodium intake can lead to high blood pressure.

This is relevant because many protein supplements contain moderate to high levels of sodium.

Some animal-based protein powders, like whey and egg white protein powder, naturally contain a moderate amount of sodium.

Some plant-based protein powders, especially pea protein powders, are high in sodium because they contain plant protein concentrates and/or isolates, which are made using a dilute salt solution.

If you are on a low sodium diet for high blood pressure, I highly recommend hemp, collagen, or nut-based protein supplements, as they are all low in sodium.

Keep in mind that what you mix your protein powder with can add a considerable amount of sodium.

1 serving of milk, for instance, could add over 100 milligrams of sodium to your shake.

If this is a concern for you, it is recommended that you mix your protein powder with water.

It is worth adding that some protein powders contain added caffeine, which can temporarily raise blood pressure.

If this is a concern for you, avoid metabolism-boosting or thermogenic products formulated with caffeine-rich ingredients such as green tea extract.

What Is the Best Protein Powder for High Blood Pressure?

As long as it is low in sodium and caffeine-free, the type of protein powder you use does not matter if you have high blood pressure.

Ingredients do matter, however.

Regularly consuming certain protein powder ingredients, namely food additives and protein concentrates and isolates, could indirectly cause high blood pressure.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other ultra-processed can alter the composition and function of your gut microbiome (North Clin Istanb, 2019).

These shifts, known as gut dysbiosis, have been linked to high blood pressure (Hypertension, 2015).

Gut dysbiosis might contribute to hypertension by curbing the production of beneficial short-chain fatty acids, increasing inflammation, and disrupting metabolic and immune pathways.

⚠️ Here is a list of the most common food additives in protein supplements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Protein concentrates and Isolates

You might also want to avoid ultra-processed protein concentrates and isolates.

Most protein supplements are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help your gut break them down.

You therefore do not digest them in the same way that you do whole foods, which could affect your gut health.

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
