Joint comfort (as part of CFA blends)

Limited Evidence

Small trials of CFA blends suggest modest improvements in joint comfort and function. Direct evidence for cetyl palmitoleate as a single agent is lacking.

How it works

Cetylated fatty acids are theorized to act as joint lubricants and to influence cell membrane composition and inflammatory signaling. The mechanism is not well established, and most research has been conducted on mixed CFA preparations rather than cetyl palmitoleate alone. In supplement products, cetyl palmitoleate is typically one of several ingredients in a 'CFA complex' rather than the primary active.

Dosage

There is no established RDA. DSLD does not provide a median dose for this entry. Follow product directions for the full CFA blend rather than the individual ester.

When and how to take it

Take with a meal containing some fat to support absorption. No specific time of day is required.
