Exclusively developed by 4Life, PRO-TF® is powered by a patent-pending blend containing low molecular weight, extensively hydrolyzed (high DH), and ultra-fast absorption whey and egg protein. (High DH proteins are absorbed faster, more easily digested, and more effectively utilized by the body than other forms of protein.) PRO-TF® is your total protein infusion!*

PRO-TF® has been independently and university-tested to support:

  • Calorie and fat burning*
  • Muscle growth*
  • Muscle protection*
  • Increased metabolism*
  • Hunger suppression*

Plus, PRO-TF® is gluten-free and contains zero grams of lactose.

Every serving of PRO-TF® provides ten grams of one of the most advanced and effective proteins available to help you transform your body, optimize performance, and promote health. PRO-TF® includes a critically essential protein source, plus 300 milligrams of the exclusive immune system support of 4Life Transfer Factor® in every serving.* Two servings per day are recommended to get 20 grams of protein and 600 milligrams of 4Life Transfer Factor® Tri-Factor® Formula. Check the protein calculator on the label or the 4LifeTransform® App to determine your individual protein needs.*

The Low Molecular Weight PRO-TF® Protein Blend was tested in an independent, pre-clinical university study and shown to significantly increase muscle protein synthesis (muscle growth) by 74% and was the leading whey protein in the following areas1:

0 %

Stimulates fat burning markers from visible/surface fat for up to 3 hours2*

0 %

Stimulates fat burning markers from “bad fat” stores for up to 3 hours2*

0 %

Reduces hunger cravings markers for up to 3 hours2*

The Power of Protein

Do you dream of a day when you wake up feeling your best? Not only would you feel healthy and ready to go experience life, but you’d also be proud of your reflection as you look in the mirror. Protein can help you get there! Transform your body with quality protein to help you burn fat, gain muscle, and achieve the optimal health needed to live a vibrant life.

There’s a good chance you’re already consuming some protein in your diet every day—but are you consuming enough of the right kind of protein to help you meet your goals? Learn how supplementing your diet with high-quality protein such as PRO-TF® can help you transform your body and your life.

Five reasons you need protein:

Protein supports fat burning in healthy adults of all ages. It’s a great addition to any healthy eating and exercise program. Not only can protein help you achieve your ideal weight, it can also help you feel fuller between meals and reduce cravings for unhealthy junk food that can derail your efforts.

Protein can help protect healthy muscle in people of all ages, by increasing muscle growth and reducing muscle breakdown. A diet higher in protein than carbohydrates has been reported to provide the greatest benefit for reducing the adverse effects associate with age-related muscle and strength loss—the two factors most highly correlated with quality of life in later years.1 This makes protein an essential supplement for older adults who want to age well.

Embrace an active and healthy lifestyle. Whey protein can be a powerful and effective tool to transform both your body and your health. Whether you want to support healthy blood glucose levels and appetite, improve sports performance and recovery, or just look and feel better, protein can help you achieve your goals.

Protein supports healthy muscle mass and a healthy immune system. Because muscles release signaling molecules that communicate with the brain, liver, pancreas, bones, fat tissue, and many other organs, the healthier and more active your muscles, the healthier your overall immune system response will be.2

Ever dream of the day when you were truly happy with your body—not just for a few weeks of strict calorie deprivation and beating yourself up at the gym—but for the rest of your life? No matter your body transformation goals—to loose body fat or gain muscle—protein can play a significant role in helping you achieve and maintain your ideal body composition. Even people who consider themselves to be “too skinny” can add more quality muscle (in combination with a healthy diet and exercise) versus those who primarily eat high glycemic carbohydrates or fat.3
