Omega 3 / 6 -- and Fish Oil info..

So i've been studying this site, and found some information on here that i haven't really studied that much before, so I though this would be worthy of a new thread. It's a bit lenghty, and a big site, but I think this link covers Omega 3/6 and fish oil very well. (And very unbiased IMHO / nor trying to sell product.)

One thing that I didn't know (besides from taking a multi of course anyways) is that a Vit E sup. seems almost essential while taking fish oil...

Supplementing with fish oils has been found to be entirely safe even for periods as long as 7 years and no significant adverse effects have been reported in hundreds of clinical trials using as much as 18 grams/day of fish oils. Fish oil supplementation does, however, lower blood concentrations of vitamin E so it is a good idea to take extra vitamin E when adding fish oils to your diet. A clinical trial carried out by the US Department of Agriculture found that taking 200 mg/day of synthetic vitamin E (equivalent to about 100 IU of natural alpha-tocopherol) is sufficient to completely counteract this effect of fish oil supplementation. [74, 75, 77, 78]

If you want more vitamin E:

Eat more spinach, chard, broccoli, sunflower seeds, mixed nuts, tomatoes, pumpkins, canola and olive oils.

Don't pop another pill. Besides, vitamin E is fat soluble, so I doubt this is a concern in healthy people.

To Monger...

it seems a fish of the coast of New Zeland named "Hoki" is the best source of DHA and EPA through Omega 3 fatty acids.

An excerpt from the site above...

Swedish researchers also confirm that fatty, cold-water fish are the best sources of EPA and DHA and that the conversion rate of alpha-linolenic acid (flaxseed oil) to EPA is very low, even in healthy humans – probably in the order of 2-5%.

Ahh, yea i didn't think of it that way when i was reading the article Madmick. I wasn't taking into consideration that some people eat right, and consume enough vegatables (nor take multi's) I was going more along the lines of people who don't eat clean, and are very deficient in vitamins and nutrients already.

Thanks for remembering me!

Great information but it's not all that relevant when buying Omega-3 supplements (as we talked about in a previous thread). This is because you can always look at the nutritional table to find the amounts of DHA and EPA. As I alluded to in the other thread, it's better to look at these ratios on the bottle when doing comparative shopping vs. looking to see what fish the oils is coming from. Thanks again for the info, its interesting!

Yep, I'm going to have to agree with you. It seems after looking around and researching, most companies use different fish as a sales gimmick(IMHO). It's not really "where" it comes from (as in fish) but more of, as you said, how much DHA and EPA and the quality (pharmecutical grade) of the product that counts.

The only real thing I can see comparing when shopping is being aware of the *type* of pills you are buying. Definately want to buy the molecularly distilled pills, and from what I collected, the best ones are always packaged hidden from light. (Whereas cheaper ones will be in a bottle that doesn not block out light / uv).
