The Proof Is in the Products

Long-Term Weight Loss Study:

Dr. Paul Arciero and his team of researchers recently analyzed how combining Shake Days and Cleanse Days (when used as part of a system), in addition to other Isagenix products, can help improve body composition and contribute to better overall health during weight loss. The results of this study* also offer evidence that shows participants obtained better long-term weight maintenance compared to a traditional heart-healthy diet. Study participants were observed over a 15-month span while using products such as IsaLean™ Shake, IsaLean Bar, Cleanse for Life®, and Complete Essentials™ Daily Pack to name a few.

Performance Study (Women):

A recent study* has demonstrated that physically active women who used Isagenix products for increased protein intake while engaging in an exercise program enhanced their muscular endurance, strength, power, and cardiovascular health. Participants used products such as IsaPro®, IsaLean PRO Shake, IsaLean Bar, e+™, Replenish (now AMPED™ Hydrate), Ionix® Supreme, and Complete Essentials Daily Pack. Researchers found that receiving quality nutrition offered in Isagenix products yielded better results compared to participants that used other supplements and a lower protein intake, maximizing users’ return on investment from working out.

Performance Study (Men):

A recent study* has found that physically fit men who used Isagenix products to boost their protein intake and improve their nutrition when training, observed a significant enhancement in their muscular power, strength, aerobic performance, and flexibility. The study also suggests that Isagenix products, in conjunction with a higher protein intake, support training-induced improvement in several performance outcomes – which includes positive adaptations for strength, power, endurance, and increased muscle growth (as indicated by IGF-1, a known marker for muscle growth).

Healthy Aging Study:

A recent study* has found that IsaGenesis®, when taken on a daily basis, can support the body’s concentration of catalase, an enzyme that is highly regarded as a biomarker of healthy aging.† Catalase was found to increase its circulating levels by 15 percent within study participants who supplemented their diets with IsaGenesis. Additionally, catalase plays a role in protecting telomeres (the protective caps found on the end of our chromosomes).
