Omega-3 polyunsaturated fatty acids (PUFA) which are found in fish oil, have been studied in a wide variety of diseases, ranging from Alzheimer’s disease to Herpes Zoster (shingles). Omega-3 PUFA have proven anti-inflammatory and neuroprotective properties and have been used to treat rheumatoid arthritis, Crohn’s disease, ulcerative colitis, psoriasis, lupus erythematosus, multiple sclerosis, as well as migraine headaches.
A new study just published in Neurology showed a strong beneficial effect of Omega-3 PUFA in the treatment of diabetic nerve damage, or diabetic sensorimotor polyneuropathy in patients with type 1 diabetes. After one year of taking 750 mg of EPA and 560 mg of DHA (two of the main omega-3 fatty acids) there was a significant improvement in the nerve function.
Omega-3 PUFA are proven to help patients with coronary artery disease, while in many other conditions, including migraines, the evidence is not as strong. However, considering that we have a very large amount of data showing a benefit in a wide variety of conditions and that Omega-3 PUFA are very safe and inexpensive, it is reasonable to try EPA with DHA for any auto-immune or inflammatory condition, as well as depression.
Eating fatty fish, such as salmon and sardines 2-3 times a week can be sufficient for general health, but those with coronary artery disease and other conditions could benefit from a daily supplement. Also, fish often contains mercury, which can cause neurological and other problems. Omax3 and prescription fish oil, Lovaza are my preferred products because they contain no mercury and are highly concentrated, requiring only 1 or 2 pills a day.
