Cetylated fatty acids are a group of naturally occurring fats. But cetylated fatty acids used as medicine are often made in a lab. These fats include cetyl myristoleate, cetyl myristate, cetyl palmitoleate, cetyl laurate, cetyl palmitate, and cetyl oleate. Cetyl myristoleate receives the most attention. Many products containing cetyl myristoleate also contain a mixture of these other cetylated fatty acids.

Cetylated fatty acids are commonly used for osteoarthritis. They are also used for other types of arthritis, knee pain, fibromyalgia, and other conditions, but there is no good scientific evidence to support these uses.

Natural Medicines rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

Cetylated fatty acids might help lubricate joints and muscles, soften tissues, and increase flexibility. It also might help the immune system and reduce inflammation (swelling).

When taken by mouth: Cetylated fatty acids are POSSIBLY SAFE when taken by mouth, short-term. Side effects have not been reported. But there is not much information available about the safety of long-term use.

When applied to the skin: Cetylated fatty acids are POSSIBLY SAFE when applied to the skin, short-term. Some people might be sensitive to creams containing cetylated fatty acids.
