Omega-3 Side Effects

Heartburn or indigestion, bad breath, and diarrhea are some of the common gastrointestinal problems that may occur as side effects of omega-3 fatty acids. These can often be eliminated by keeping any fish oil products in the freezer. Potentially serious reactions that should be reported to a healthcare provider right away include high blood sugar, signs of bleeding, and allergic reactions.

However, even though they are "natural" products, omega-3 supplements may cause problems. For most people, these side effects are merely bothersome. However, potentially serious reactions are possible, especially when taken at higher dosages, which is often necessary in order to obtain some of the omega-3 benefits.
