Overhead view of various foods , fish, nuts, vegetables and more

Did you know that after water, protein is the most abundant substance in the body? We literally can’t live without protein. Protein is one of the body’s most basic building blocks and it’s not just for building lean muscle. Protein can be used to help develop bones, skin, and cartilage — while also promoting satiety and weight loss. Here are some other protein facts you may not know:


  1. Protein exists in every single cell in our body. Without protein, life would not exist.
  2. According to research, protein is the most satiating macro, which helps explain why high-protein diets help promote weight loss and weight-loss maintenance.
  3. Protein is made up of 22 amino acids, nine of which are essential, meaning we have to get them through food because our bodies cannot produce them.
  4. Each gram of protein provides 4 calories.
  5. You have to eat protein every day. The body can’t store protein like it can carbohydrates and fat.
  6. The lifespan of a protein in the body is two days.
  7. Approximately one-fifth of our body weight is protein.
  8. On the go or after the gym, in between meals, as a snack, or even right before bed – protein shakes are a super convenient way to meet your protein intake daily.
  9. You can cook with protein powders. From muffins, pancakessmoothies and smoothie bowls, to waffles, cookies and cake, you can satiate that sweet-tooth while boosting protein intake.
  10. Modern Source Plant-Based Protein is comprised of a unique blend of organic rice protein isolate, pea protein isolate, potato protein and cranberry protein in specific ratios to help give it a strong amino acid profile ideal for those who are vegan and love to exercise.
  11. The first flavor of PRO7EIN Synthesis™, which contains 34g of quality protein per serving, came out over a decade ago. White Chocolate Peppermint is the ninth addition to the already impressive lineup of crave-worthy flavors like Peach Mango, Cookies and Cream, Caramel Pretzel and Pumpkin Spice.
  12. Yellowfin Tuna contains the most protein (30g per 100g serving) of all fish. It is followed by anchovies (29g), salmon (27g), halibut (27g), snapper (26g), and tilapia (26g).
  13. Low-sodium parmesan cheese contains the highest amount of protein found in cheeses at 41.6g per 100g serving (but that’s about a half a cup of cheese!).
  14. Pumpkin seeds provide 33g of protein per 100g serving.
  15. Crickets, however, provide 60g of protein per 100g serving (that’s about 3.5 ounces). Chirp!
