How can Instaflex® Advanced help me?
Instaflex® Advanced relieves discomfort and stiffness in the knees and joints. Feel significant improvements in comfort, mobility, and flexibility starting in one week. Get back to enjoying life with friends and family and doing the things you love again.

How is it different from other joint supplements?
Instead of simply masking the soreness and tenderness, target the problem at the source with a doctor-created formula backed by clinical research and cutting-edge science to NOURISH and REVITALIZE your joints. With TWICE the power of glucosamine + chondroitin, Instaflex® Advanced significantly improves joint comfort, mobility, and flexibility starting in one week. Improvements in knees and joints can increase with continued daily use, for up to 90 days.

It’s results like these that make it the #1 selling joint formula at GNC stores nationwide. For powerful support, enjoy the convenience of one tiny pill, taken once daily. No other joint supplement contains the same powerful combination of ingredients, at the exact level of potency confirmed in scientific studies. The ingredients in Instaflex® Advanced are safe, non-habit-forming, and drug-free. Instaflex Advanced is even, independently verified for quality and potency by Consumer Lab, a leading authority on supplement testing.

What’s in it?
AprèsFlex®: A highly-concentrated form of Boswellia Serrata, which has effectively helped with joint discomfort for thousands of years, especially in the knees. Clinical studies show AprèsFlex® can significantly improve discomfort in as little as 7 days, with results improving with continued daily use.

UC-II® Collagen: A patented form of undenatured type II collagen that’s twice as effective as glucosamine and chondroitin at improving joint discomfort, stiffness, and mobility. And it’s safe if you have a shellfish allergy.

Turmeric: An Asian herb providing additional joint support by lowering histamine levels.

Resveratrol: A natural polyphenolic compound, commonly associated with wine, that has powerful antioxidant properties.

BioPerine®: A black pepper extract that increases the bioavailability of nutrients through increased absorption.

How do I use it?
Take one capsule a day with water.

How many bottles should I order?
Our bestselling bundle offer is the 3-bottle package. However, because our customers take Instaflex® Advanced regularly on a recurring basis, we recommend the 5-bottle package for the deepest discount.

What if I’m not seeing the results I wanted?
