The Ingredient That Sets
Flexcin Apart
Most joint supplements stop at glucosamine. Flexcin adds CM8™.
What is CM8™?
CM8™ is Flexcin's purified form of cetyl myristoleate (CMO), a naturally occurring fatty acid ester. It works alongside glucosamine rather than replacing it, as part of a formula made to support joint comfort and flexibility.
CM8™ is the signature ingredient in every Flexcin formula. Combined with MSM, Hydrolyzed Collagen Type II, Bromelain, and Glucosamine, it makes a complete daily joint formula.
"I'm a senior golf pro, and I've used Flexcin for 20 years to keep mobile."
