Why Most Protein Powders Are a Scam
ESTIMATED READ TIME: 4-5 MINSWalk down the supplement aisle or browse Amazon, and you'll find dozens of protein powders claiming to help you build muscle, lose weight, recover faster, or stay full longer.
I'm certainly not against consuming more protein—and in fact, I believe getting enough is one of the most important things you can do for your health, especially as you get older.
The problem is that many protein powders are marketed as health foods even though they're made with highly processed whey, along with added sugar, artificial sweeteners, thickeners, and other fillers.
The quality of your protein is just as important as the quantity that you consume. Here are four reasons I encourage people to look beyond marketing claims and take a closer look at the ingredient label before choosing a protein powder.
Many Protein Powders Are Highly Processed
Protein should come from real food, first and foremost, not a chemistry experiment. Unfortunately, most popular protein powders undergo extensive processing before they ever reach the container on your shelf.
Some are exposed to high heat, harsh chemicals, or multiple manufacturing steps that can alter the natural structure of the protein, while also sometimes removing beneficial compounds that originally accompanied it.
Others are little more than isolated protein mixed with artificial flavors, gums, synthetic vitamins, and preservatives. Some are even contaminated with heavy metals and other concerning ingredients.
A 2025 analysis by the Clean Label Project tested 160 of the top-selling protein powders and found that 47 percent exceeded at least one federal or California safety threshold for heavy metals such as lead, cadmium, arsenic, or mercury.
Plant-based protein powders were found to contain approximately five times more cadmium than whey-based powders, largely because plants absorb heavy metals from the soil in which they're grown.
Quality varies tremendously from brand to brand. I prefer protein supplements from reputable brands that test their products and are as close to their natural source as possible, whether that's grass-fed beef protein, collagen peptides, bone broth protein, or minimally processed whey.
Read the Ingredient List, Not Just the Protein Count
It's easy to flip the container over and look for one number: grams of protein.
How much protein you get in every serving is important, but I care even more about everything else in the container. I recommend only consuming protein powder that isn't made with:
Artificial sweeteners, such as sucralose and Acesulfame K
Artificial flavors
Artificial colors
Seed oils
Maltodextrin
Excess gums and thickeners
Fillers that add little nutritional value
A protein powder shouldn't need a long list of ingredients to taste good or provide you with actual protein. The best products contain only a handful of recognizable ingredients, so whenever possible, look for those that prioritize quality.
Here are some tips for reading protein powder labels:
A short ingredient list with recognizable, whole-food-based ingredients
Clean powders over sugary "protein" gummies, bars, and ready-to-drink shakes
At least 20 grams of protein per serving from a high-quality source
Protein sourced from grass-fed, pasture-raised, or responsibly raised animals whenever possible
Minimal added sugars, artificial sweeteners, gums, fillers, or preservatives
Third-party testing or quality certifications that verify purity and screen for contaminants like heavy metals. Supplements aren't required to undergo FDA approval before being sold, so voluntary third-party testing is important
Transparent sourcing, so you know exactly where the protein comes from and how it's produced
Products that fit your individual goals, whether that's collagen peptides for skin and joints, bone broth protein for gut support, or a complete protein such as grass-fed whey for muscle maintenance
Just Because It's High in Protein Doesn't Mean It's Healthy
Another factor to consider is how well you actually tolerate the protein source. Whey and other dairy-based protein powders, for example, may contain A1 beta-casein unless they're specifically made from A2 dairy. Some people find A1 dairy more difficult to digest and experience symptoms like bloating or digestive discomfort.
Plant-based proteins aren't automatically easier on the gut, either. Soy and pea protein can be difficult for some people to digest, meaning a powder can look impressive on the nutrition label while still leaving your stomach unhappy.
That's why I look beyond grams of protein and consider the quality, digestibility, and nutritional value of the source itself.
Some protein sources also provide beneficial nutrients and compounds that highly isolated proteins simply don't. These are some of my top picks:
For example, collagen supplies amino acids such as glycine and proline that support healthy skin, joints, connective tissue, and gut integrity. It can be especially helpful as we age, when our natural collagen production begins to decline.
Bone broth protein naturally contains collagen peptides along with other compounds traditionally valued for digestive health, joint support, and maintenance of the integrity of the intestinal lining.
Eggshell membrane protein remains one of nature's highest-quality complete proteins and also provides naturally occurring collagen, glucosamine, chondroitin, and hyaluronic acid—compounds that support healthy joints, cartilage, and connective tissues.
Different proteins serve different purposes, which is why eating a variety of protein-rich whole foods and even combining protein powders, is usually better than relying exclusively on one or two supplements.
Protein Powders Should Supplement Your Diet, Not Replace Real Food
A common mistake is to treat protein shakes as meal replacements every day. There's a time and place for a convenient shake, such as after a workout, while traveling, or during a busy morning.
But I never want a protein powder to replace the nutrition found in whole foods, especially those rich in protein as well as essential vitamins, minerals, and fats, such as:
Eggs
Grass-fed beef
Wild-caught fish
Lamb
Organ meats
Fermented dairy from pasture-raised animals
Bone broth
These types of foods provide countless naturally occurring nutrients that can't be replicated in a scoop of powder. So overall, think of protein powder as a tool, but not the foundation of your nutrition plan.
Key Takeaway: Choose Protein That Resembles Real Food
Protein powders aren't inherently bad, and in fact, some—such as a quality collagen powder or bone broth protein powder—can be excellent.
But others are little more than ultra-processed convenience foods wearing a health halo. When buying a protein powder or supplement, ask yourself a few simple questions:
Where did this protein come from?
How heavily was it processed?
Can I recognize every ingredient on the label?
Would I feel good consuming this every day?
For me, it's key to prioritize nutrient-dense whole foods first, use high-quality protein powders for extra nutrients or when needed for convenience, and remember that no supplement can replace a healthy diet built on real, nourishing foods.
That's an approach that supports not only stronger muscles, but also better health for years to come.
