Is there such a thing as vegetarian omega 3's?

Is this for real?

Are they in a bio-available form? Wouldn't the phenols and phyto-chemicals be detrimental to absorption?

I currently take chlorella and spirulina daily, as well as 2000-3000mg of wild Norwegian Salmon oil. Am I being redundant?

Isn't eating seeds inadvisable?

ALA from flax and walnut can be translated to EPA/DHA in the body. It is 18:3 (n−3) acid. So its not very long. EPA(20:5, n−3) and DHA(22:6, n−3) are longer, particularly DHA which works in brain. I doubt longer molecule can cross BBB more then shorter. There might be some transport system for DHA that is not there for ALA, since 3D structure is not that similar.

Yes you have to find the right algae DHA supplement because most of the stuff is packed in sunflower oil so you are getting a healthy dose of o3 and unhealthy dose of 09 and 012.

I have vegetarian friends that have to order their algae based omega 3s from Europe, not sure why, maybe they're not produced in the States?

Flax doesn't cross the blood/brain barrier though. I've worked with women dealing with postpartum depression, and flax oil doesn't help, but fish oil does.

Anti-nutrients don't really have anything to do with the digestion of the macromolecules. See: http://www.vivo.colostate.edu/hbooks/pathphys/digestion/smallgut/absorb_lipids.html

The supplement contains DHA (Docosahexaenoic acid) produced from algae.

As far as I know the long-chain omega-3 fats in fish oil originate from algae. In the sea Algae are at the bottom of many food chains and the omega-3 fats they produce work their way up to be concentrated in larger carnivores such as fish.

Producing DHA from algae is not complicated however each algal cell only produces a tiny droplet of lipids. You have to grow up a huge amount of algae to get much oil but this is less of a problem now with modern growing systems if you use the right kind of algae.

If you separate the oil from enough algae you have quite a pure source of DHA.

Producing quantities of EPA from algae is much harder but I understand people are working on solving this problem.

When this process becomes cheap enough I think it will be used to replace most fish oil supplements. I might help to stop us fishing the worlds oceans until they are empty. There isn't enough fish left now to provide everyone with fish oil.

Chia seeds are omega-3 powerhouses. Ever read Born to Run? They are becoming trendy now, there are several products available at Whole Foods

Yes. Eggs are vegetarian and a good source of omega 3s--especially if they are pastured. And if you are actually asking about vegans, again yes. Walnuts and flax seed also have omega 3s.
