Peanut Butter Toffee"Nutrex Research ISO Fit protein is the best protein I’ve ever tried! It’s smooth, tastes great, and it’s lactose and gluten free. What more could you ask for?!?!?!?! This is the way to go!" - Tania O. |
Vanilla Bean Ice Cream"Many powders either taste gross, mix terribly and stay clumpy, or both. This protein powder is absolutely delicious mixed with almond milk or water and never clumps. Not a meal replacement, but does make a great breakfast smoothy blended with fruit and/or coffee and heavy cream." - Heather S. |
Banana Foster"I’m not a protein person AT ALL. The smell bothers me a lot, however, this protein tastes and smells amazing! I mix it in with smoothies or my morning coffee and I don’t ever detect it. Highly recommend!!" - Kelsey S. |
Chocolate Shake"I've been in health and fitness for over 15 years and can honestly say this ISOFIT is one of the best proteins ever!" - Lonnie H. |
Why Choose IsoFit?
Don’t settle for less than “ultra-clean” ISOFIT, made with MCT oil powder and organic agave inulin fiber instead of inferior inflammatory thickening agents. Plus, our unparalleled delicious gourmet flavors and easy mix-ability make every scoop of ISOFIT a true tasting experience.†
