Allmax IsoFlex (Best By 07/2026)

The Best Whey Protein Isolate on the Market

ISOFLEX: 100% Pure Whey Protein Isolate Powder uses a unique protein extraction technology called Hybrid-Ratio Ion-Filtration (HRI). A hybrid of two isolate purification technologies incorporated at a specific ratio to produce a truly superior ultra-pure Whey Protein Isolate powder. Cutting-edge HRI Technology allows ISOFLEX to retain an exceptionally high protein yield while maintaining enhanced bioactive whey fractions. This process is one of the reasons Isoflex is considered by many to be the best whey protein isolate on the market today.

ISOFLEX CONTAINS ABSOLUTELY NO WHEY CONCENTRATE!
Concentrates have higher levels of fat and sugars with a lower percentage of protein and lower bioavailability than Isolates. While other brands use Concentrates, ISOFLEX users know that Isolates have a superior protein percentage and won’t settle for non-Isolate blends.

That’s right, Pure Whey Protein Isolate at your fingertips, giving you a whopping 90% protein content! With only Native and Intact, Non-Denatured Whey Protein Fractions. 27 g of Pure Protein that has been laboratory tested, certified and approved.
