Overview Information

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

Cetylated fatty acids are commonly used by mouth and applied to the skin for osteoarthritis. Cetylated fatty acids are also used for other types of arthritis including rheumatoid arthritis (RA), Reiter's syndrome, and ankylosing spondylitis, along with many other conditions. But there is limited scientific research to support these other uses.

How does it work?

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).


Uses & Effectiveness?

Possibly Effective for

  • A type of arthritis called osteoarthritis. Taking a specific blend of cetylated fatty acids combined with soy lecithin and fish oil by mouth seems to decrease pain and improve knee motion in people with knee osteoarthritis. However, this combination does not appear to improve knee stiffness in the morning. Applying the same specific blend of cetylated fatty acids directly to the skin either alone or in combination with menthol also seems to decrease pain and improve function in patients with knee osteoarthritis.

Insufficient Evidence for

  • Rheumatoid arthritis.
  • Systemic lupus erythematosus (SLE).
  • Multiple sclerosis.
  • Reiter's syndrome.
  • Behcet's syndrome.
  • Sjogren's syndrome.
  • Psoriasis.
  • Fibromyalgia.
  • Emphysema.
  • Benign prostatic hyperplasia (BPH).
  • Silicone breast disease.
  • Leukemia and other cancers.
  • Various types of back pain.
  • Other conditions.
There isn’t enough evidence to rate the effectiveness of cetylated fatty acids for these uses.

Side Effects

Side Effects & Safety

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

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of cetylated fatty acids during pregnancy and breast-feeding. Stay on the safe side and avoid use.



We currently have no information for CETYLATED FATTY ACIDS Interactions.



The following doses have been studied in scientific research:


  • For osteoarthritis: 1050 mg of a specific blend of cetylated fatty acids plus 150 mg of soy lecithin and 225 mg of fish oil taken 6 times daily.
  • For osteoarthritis: a specific blend of cetylated fatty acids applied twice daily to the affected joint
