GNC sells DHA supplement pills. DHA can come from fish or algae, but it doesn't say on the bottle. Does anyone know where it comes from?<br><br><br><br>
DHA is 1 of 2 omega-3 oils not found in flax oil. The other is EPA.

If it doesnt say, its probably fish. THe ones using algae are fairly new and they like to brag about it ;-) Get DHA supplements made from algae, I was not able to find them at GNC or Vitamin Shoppe but I was able to find them at my health food store, and at Whole Foods. THey are EXPENSIVE though!!<br><br><br><br>
Another note: It is widely considered that people can create DHA in their bodies from ALA and other omega 3 sources. I am taking DHA supplements because I am pregnant, but I was fine with flax and other omega 3 sources before that. There are millions of Jains in India and the US who have never had fish or eggs pass their lips and they are in perfectly good health. My friends who are Jain eat nuts every day for their "healthy fats" as they say ;-)

I'm having trouble with tendinitis in my knees, so I wanted to try it.<br><br><br><br>
Yeah, I've read that people can make dha and epa from ala, but I've read that sometimes it isn't converted efficiently. I've been on flax oil for a long time now. Just something to try.<br><br><br><br>
But it seems that in the history of the world, there must have been people that didn't have access to fish for dha and epa.

Yep...and in the history of the world most people died by age 35. <img alt="" class="inlineimg" src="/images/smilies/wink3.gif" style="border:0px solid;" title=";)"><br><br><br><br>
Why don't you call the manufacturer and ask how they derive their pills? I also take vegan DHA specially marked as vegan.

well according to dr. fuhrman in his book "eat to live" people can easily ocnvert omega 3's found in flax, walnuts, etc... to DHA and EPA and thats why those fats arent considered essential

are you sure that it's both? i was quite certain not DHA. i am not going against what you are saying, i've just been studying dietetics and health for a while and never heard that. can you reference it, and then i can grab the book?

"Another case in which fish oils may be useful is the rare individual who does not convert omega-3 fats into DHA sufficiently" page 127<br><br><br><br>
About Flax>"The body can manufacture EPA and DHA from these omega-3 fats for those of us who do not consume fish" page 183<br><br><br><br>
but let me say that i dont know much about dietetics yet. although i am in my first nutrtion class right now<img alt="" class="inlineimg" src="/images/smilies/dancingbanana.gif" style="border:0px solid;" title=":nana:"> and eventually want to become a registered dietician.

It's both but the conversion isn't very efficient. The efficiency depends on several factors. Most vegans/vegetarians consume too much omega 6. The omega 6/ omega 3 ratio is too high and that reduces the conversion efficiency. To say that people convert omega 3 easily, that's not true.

Thanks for the replies. Good for you on the RD path - it was mine, too! Have a blast. I'm going to get the book from the library.<br><br>
Kyo - thanks for the reply, also

You're welcome laurie15 and thanks for responding to my post. I'm not studying to become an RD if that's what you mean but I've read up on omega-3 and a few other things. The book "Becoming Vegan" discusses omega-3 and it's written by 2 RDs. I read about it there and a few other places. Later I'll post some quotes from the book.

Ironically, I have that book. I just haven't read it again since I've been looking more into this. I'll check it out - thanks!

Its funny you should mention this. I just read 'Healthy at 100' by John Robbins, and he discusses the 'Hunza' who are known for living very long healthy lives, and not suffering from the debilities that we usually assume are just part of the normal aging process. These people keep perfect vision and never even get presbyopia (which kicked in for me at age 46). When I found out that they have been sprinkling flax seed on everything they eat from time immemorial, I went right out and bought another bag of it! They have traditional always gotten their omega-3's in their diet, and it has not been from fish.<br><br><br><br>

Kyo, I agree with you that it is both, and I do not believe that this is actually a point of controversy. The controversies and confusion seem to surround the issue of how efficiently the conversion of ALA into EPA and finally DHA happens in various individuals and why. ALA is a short chain omega-3, and EPA and DHA are longer chain omega-3's, with DHA being the longest chain of the 3. The process of conversion from ALA to DHA is not direct, in the sense that the body first converts the ALA to EPA before it finally becomes DHA. In other words, it takes more processing for the body to reach the end result. Laurie, perhaps you got confused because of that intermediate step that the ALA has to go through before it finally becomes DHA? That is, because it isn't actually a direct jump from the short chain ALA straight to DHA.<br><br><br><br>
Kyo, that is a good point about the Omega 6's. I recently asked Dr. Fuhrman (on his member website) about why some people convert the ALA from flaxseed into EPA and DHA more efficiently than others. He said that it was partly due to genetics, but also that the more omega-6 eaten competes for the desaturation enzymes that convert the short chain omega-3 into the longer EPA and DHA. Basically, it is very common for people to overload on the Omega-6's, and they compete for the same resources that the body uses to convert the short chain omega-3's into DHA. If you eat a fat deficient diet (no nuts,seeds, or avocado) with lots of grains in it, then you end up with too many omega-6's, and get this imbalance. As I see it, this problem was actually encouraged when the U.S. gov't decided to put grains at the bottom of the food pyramid, while training us all to be fat-phobic.<br><br><br><br>
