Fish oil side effects are something everyone should be worried about, but the good news is that they are easily averted by knowing what to do. The main reason most people are worried about fish oil side effects is because of all the talk about fish swimming in polluted waters and so on.

Studies have shown that there exist certain types of fish in certain parts of the world which are very pure and practically free from any heavy metals and toxins. With all that said, here are the 3 fish oil side effects and what to do about them.

1. Burping is something that can happen quite easily with omega-3 fatty acids, especially if you take them right after a meal, because you will be burping the food you ate, and that will push up the omega-3's as well. But did you know that the higher quality supplement you use, the less burping you will have?

2. Gas can happen if you're using a supplement that has gone rancid or is very low quality. It most likely means that your body cannot absorb the contents and causes one of the most common fish oil side effects: gas, and even bloating. The same solution applies here, look for a high quality, natural and pure supplement to avoid this side-effect.

3. Poisoning is the most serious of the fish oil side effects and happens when the product has not been properly purified and the wrong fish species are used. Always make sure your product is molecularly distilled to ensure purity and look at clinical trials that prove the effectiveness and safety.
