Product Information
Man lifting a kettlebell next to a tub of Nutrex ISOFIT Whey Protein Isolate

ISOFIT is our purest whey protein isolate ever. It’s ultra-fast digesting and absorbing for the ultimate muscle recovery support after intense training or anytime of day. Every serving of ISOFIT is jam-packed with essential amino acids (EAAs), including branched chain amino acids (BCAAs), that help ignite muscle protein synthesis for superior strength and major muscle gains. 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 mixability make every scoop of ISOFIT a true tasting experience.

ISOFIT nutritional information: 25g Protein, 12g EAA, 5.8g BCAA, 1g Sugar Key benefits of Nutrex ISOFIT: 25g protein, easy digestion, 5 gourmet flavors, and added MCTs Nutrex ISOFIT quality seals: GMP Certified, Artificial Color Free, 3rd Party Tested, and Made in USA Nutrex Research 'Be Unstoppable' banner with athletes and ISOFIT protein

I love this ISO protein. The vanilla flavor is good, nothing overpowering or underwhelming. Always grab this during the sales. M&S sales are unmatched as well…thanks*

The Chocolate Shake Flavor was great, and as expected tasted sweet enough and had a natural chocolate taste. The Cookies & Cream didn't taste like I expected and definitely needed additions to help with the taste (i.e. sugar free chocolate syrup, and vanilla unsweetened almond milk). Would buy chocolate again, but not cookies & cream; looking forward to try bananas foster next*

Feels too thick for the recommended 5oz of water. Mixes very well with water. Looking forward to see how it performs in terms of digestion and muscle recovery.*
