Estraflex® CMO (Cetylated Fatty Acids)

Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

Estraflex® CMO supplies cetylated fatty acids, a group of fats including cetyl myristoleate (CMO) studied for joint health. These specialized fatty acids appear to lubricate and calm the joints, and clinical research has examined them for improving comfort and function in osteoarthritis.

Studied Dose Commonly around 350 to 500 mg of cetylated fatty acids per day.
Active Compound Cetylated fatty acids, including cetyl myristoleate (CMO) and related cetylated esters.

Benefits

Joint function

In a randomized controlled trial, cetylated fatty acids improved knee function in people with osteoarthritis, supporting their joint-comfort positioning.

Joint comfort and mobility

Cetylated fatty acids are studied for easing joint stiffness and improving range of motion and everyday movement.

Joint lubrication

The fatty acids are thought to support the lubricating quality of joint tissue and fluid.

Mechanism of action

1

Membrane and lubrication support

Cetylated fatty acids incorporate into cell membranes and joint tissue, where they are thought to improve lubrication and reduce friction.

2

Anti-inflammatory action

The cetylated esters appear to calm inflammatory signaling within the joint, easing discomfort.
