Better to drink flaxseed oil or fish oil for omega3? Is the omega3 that comes from fish the same quality as from vegetables? Which is digested better?

Eat fish for Omega 3. Our bodies don't convert omega 3's from flaxseed into the epa & dha readily available in fish (oil). There are some attempts to make epa & dha from seaweed & algae but otherwise, read label for epa & dha content. You won't see much from flaxseed products nor will you get much conversion either.

Fish oil advantages. Flaxseed oil contains Alpha linolenic acid (ala), an omega 3 that our bodies need to covert to the essential epa & dha oils that are found in fish oil. However, people don't convert ala to epa very efficiently & may not be able to convert it to dha at all. If one is vegan they can get dha from algae extracts. I advise purified fish oil; it is better digested if it is emulsified. See my comment:. Read more...
Irrelevant. Krill oil and fish oil are the new snake oil, both are high in omega 3 fatty acids which are extremely fragile. Omega 3 fish oils reduce triglycerides by impairing the liver's ablility to make them. However the oxidative stress caused by fish oil actually raises LDL cholesterol. Some day we may use the phrase "this is just more fish /krill oil" or "here comes the fish/krill oil salesman". Read more...

For a vegetarian, how much more flaxseed must be taken to get the same effect as fish oil?

No equivalence. Less than 5% of alpha linolenic acid (ALA) which is flaxseed oil is converted in the body to EPA (eicosopentaenoic acid) and DHA (docosahexagenoic acid) which are found in fish .Although all are omega 3 polyunsaturated fatty acid, only the fish derived fatty acid(EPA and DHA) has been found to have possible cardiovascular benefit. ALA effect is neutral. Read more...
Not always possible. For some people no amount of flax oil gives the same benefits of fish oil. This is because our bodies must convert the ALA in fish oil into the EPA & DHA found in fish oil and this is not done very efficiently & some people can't convert it at all. However, you can find vegan sources of DHA & EPA from algae. See http://chriskresser.com/why-fish-stomps-flax-as-a-source-of-omega-3. Read more...

I am becoming vegan and i'd like to know if vegan omegas (flaxseed) and vitamin d2 are good replacements for fish oil and d3.

Flax for some, NO D2. Flax & hemp seed oil are good replacements for many but not all- we need to convert the ala to epa & dha & not everyone does that well. Vegan dha from algae is available. I strongly advise against d2- see http://articles.Mercola.Com/sites/articles/archive/2011/11/30/taking-the-right-type-of-vitamin-d.Aspx vegan d3 is available.Search "plant based vitamin d3."i advise 5000 iu/day in fall & winter.
