Salmon Oil Capsules & Side Effects

Omega-3 fatty acids make up the primary ingredient in salmon oil. Salmon oil, a form of fish oil, decreases fat in your blood stream, notes Gale Maleskey, a registered nutritionist and author of "Nature's Medicines: The Definitive Guide to health Supplements." This action of salmon oil protects you from built-up fatty plaques in your arteries. Your risks of heart attacks and stroke decrease with the consumption of salmon oil. Before starting this or any supplement, speak with your doctor and obtain his advice.

Gastric Upset

A side effect of salmon oil may occur as gastric or stomach upset, reports Drugs.com. Salmon oil may irritate the lining of your stomach, causing you to feel nauseated, primarily when you first ingest the capsules. Your body will adjust to the salmon oil supplement within a few days, in most cases. If this stomach upset continues, however, and becomes bothersome, call your medical practitioner for advice. Stop this supplement until you speak to your physician.

You may suffer from belching while your body acclimates to salmon oil capsules, Maleskey reports. Belching will occur unexpectedly at different times. Burping and belching occur because of increased gas in your intestines caused by the digestion of the salmon oil. Your doctor may suggest over-the-counter anti-gas medications for you to take. Talk to your physician if this side effect continues after a few days.
