What is Optimal Omega 3 Dosage through supplement and/ or fish?

[nameless]

If I remember right, around 200-300mg/daily of EPA/DHA was found optimal for longevity purposes. Or fish 2x week should cover it.

Fish - two times per week! I eat it 2-3 times per day!

I feel that recommendation is way too below our requirement given the harsh environment of our digestive system, not to mention the flushing effect of fibre of you love veg. How on earth do we retain any benefit from one portion of fish once every 3-4 days?

With 2-3 times fish per day I would be seriously worried about heavy metal poisoning...

[Snoopy]

I've weighed this one up on one side of the scale. But I often wonder which one is worse, not getting enough quality omega 3 DHA from unozxidized unmanfactured sources OR getting a steady gradual build up of heavy metal over a lifetime... It's a tough trade off given all the positives of omega 3 coming out.......

nupi, you think there Is there such thing as an anti mercury regimen? Chelators and what not.....?

[nupi]

There is but chelation is something I would not approach without medical guidance... Done improperly, you are likely to create more damage than benefits.

Hi,

I know this thread is abandoned but there is some serious misconceptions that needs to be addressed lest other readers will take away wrong information.

Yes, we have to be careful with certain fish, especially deep sea ones which could be contaminated with mercury, PCBs etc. Shallow water fish, eg mackeral, sardines, and anchovies have less of such problems. Look at the attached file for Mercury level of various fish.

One way around this problem is to take Omega 3 fish oil supplement. There are lots of brands out there. Read the labels & select those that says purified, or distilled. Some use terms like Pharmaceutical Quality, which suggests that the fish oil has been processed to rid off mercury & other harmful substances.

Some brands say their fish oil contains Omega 3 but the Nutrition Label at the back of the bottle should also indicate the quantity of DHA & EPA (the 2 major components of Omega3) if it is purified or distilled.

Generally the ratio of EPA:DHA is usually 2:1. Those with a higher percentage of DHA usually cost more. A higher level of DHA is recommended for little children, expectant mums & older folks, as these are brain fortifying supplements. Those with active lifestyle will need a higher ratio of EPA.

If you regularly eat fish I would advise to take a lot of vitamin B1, most of fish contain thiaminase which is an enzyme that destroys thiamine.
This is why asians are more at risk at getting the beri beri disease.
