WHAT ARE THE SIDE EFFECTS
Many people who take fish oil experience digestive system upset including burping-which can be disconcerting because you may burp a “fishy” smell. But you will most likely not have that problem by taking the capsules with meals.
Also, some companies make specially designed capsules that make sure the oil makes it into the small intestine before breaking down. Such claims are advertised so you might consider their capsules to find out whether their product alleviates the problem of burping or “fish breath.” Since fish oils also have a blood-thinning effect, consult with your doctor if you are taking any blood-thinning medications.
You might have an increase in LDL cholesterol while supplementing fish oil (although, not common). If a blood test shows your cholesterol count is rising, you can take garlic supplement to help neutralize this potential effect of the fish oil.
Although people have relatively few and minor issues with the side effects of fish oil, there’s a risk that the capsules can contain rancid oil. It’s simple to check, however rust cut open the end of a capsule. If the fish oil has gone rancid, you’ll be able to smell the strong odor. You’re better off getting a fresh bottle with new capsules.
Finally, examine the label of any brand you buy to ensure the product was tested for contaminants such as heavy metals.
