Can You ‘Overdose’ On Omega-3?

Yes you can! but before you ban salmon for good, let’s have a closer look...

The thing is that you really have to take in A LOT of Omega-3 over a long period of time to over-consume on it.

The FDA* states that Omega-3 is safe if you don’t take in more than 3,000 mg of fatty acids a day, while the EFSA** says we can even go up to 5,000 mg a day

However, populations like the Inuit Eskimos and the Japanese consume much more than these upper limits, as much as 6 grams per day, and this without any ill-effects showing.

First of all. The upper limits are mainly set because Omega-3 may prevent blood from clotting in some people if taken in high amounts, so that is why the EFSA sets its limit to 5,000 mg a day and advises to tell your doctor you are taking Omega-3 supplements when having surgery planned. 

Another reason for the limit is that a lot of Omega-3 supplements come with vitamin A (like cod liver oil). As vitamin A can be toxic in high amounts, you better be careful with the amounts you take of those type of supplements. 
(Not to blow our own horn, but that is another good reason why we choose to take Krill oil as an Omega-3 supplement, but you can read all about that here :) )

Last but not least, although it is important to keep your Omega-3 intake at a healthy level, it has not been shown that taking more than 5,000 mg will provide you with even more benefits, so no need to challenge the limit... No point in taking over 5,000 mg if it won’t give you any advantage.

It is simple, if you experience nausea and loose stools after taking any supplements, or you are not sure about them, then stop taking the supplement(s) and go talk to your GP or the practice nurse for more advise.


So you can rest assured that you probably won’t ‘overdose’ on Omega-3 very easily and if you would overdo it, it is most likely that your body will tell you rather quickly...

On the other hand, the consequences of an Omega-3 deficiency can have a much bigger impact on your health, so make sure you have enough of it in your diet or through supplements. More about this later in the JellyFish blog ;)
