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.
A normal dietary intake of omega-3 fatty acids (that is, through food) is probably free of significant side effects. 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.
Many omega-3 fatty acid supplements are fish oil products, and these may cause gastrointestinal side effects. Some people find that keeping their supplements in the freezer helps reduce many of these problems. These possible side effects include:
- Abdominal pain (stomach pain)
- Diarrhea or loose stools
- Constipation (if you take it without enough water)
- Indigestion or heartburn
