I recently began taking a multivitamin that has the following stuff in one serving. You have to take three pills throughout the day to get a serving, but supposing its all at once:
: Alpha-Linolenic Acid (ALA) - 890mg
:* Elcosapantaenoic Acid (EPA) - 340 mg
:* Docosahexenoic Aicd (DHA) - 225 mg
- Omega 9
:* Oleic Aicd (OA) - 500 mg
- Omega 6
:* Linoleic Acid (LA) - 284 mg
:* Gamma-Linolenic Acid (GLA) - 200mg
There is nothing on the bottle or the website that gives you any indication of what this means. It’s basically buyer beware. I think I can say for sure that I usually do not have as much oil in my food as these capsules contain. So what kind of a diet would a person who got all these oils every day follow, and does anyone naturally follow such a diet? Do you get all these oils by following the basic food pyramid?
Perhaps you should reverse your thinking. Seek out an objective and independent source (or more) as to a nutritionally competent and medically sound recommendation of vitamins and daily dosages, and not a commercial product’s opinion.
After all, there is that disclaimer on the site … "The information on this site is for information purposes only and is not intended as a substitute for advice from a physician or other health care professional or any information contained in product labeling.

Well, let’s see. Eicosapantaenoic (not Elcosapantaenoic) acid is found in salmon. Docosahexaenoic acid is synthesized in the body from eicosapantaenoic acid. That much oleic acid could be found in maybe half a teaspoon of olive oil. Linoleic acid, α-linolenic, and γ-linolenic acids are in most vegetable oils, probably less than a tablespoon for those amounts, all told.
2.5 g of fat is really not that much. I think a decent number of people get all this in their diet, easy.
Well, Omega-6 is very common in a normal diet. You need no supplementation there. It’s in (wiki) * poultry
* whole-grain breads
* baked goods
* most vegetable oils
* flax/linseed oil
* hemp oil
* soybean oil
* cottonseed oil
* sunflower seed oil
* corn oil
* safflower oil
* pumpkin seeds
OTOH, Omega-3’s best sources are fatty cold-water fish and flax. Those numbers you give are about what the FDA suggests you should take.
There’s about 1 gram of Omega-3 in 3oz of Salmon, but it varies wildly.
So, either eat 21oz of Salmon a week, or take the pill daily.
Those aren’t vitamins, they’re fatty acids. Molecules of fat are formed by glicerol and fatty acids, so unless you live on vegetables cooked with zero oil and fat, you’re probably getting a lot more “oils” than you thought. Even if you’re living on vegetables cooked with zero oil and fat, some of them contain a lot of oil (you know, the ones from which we do extract oils).
Darn, out of time.
Omega-n means that the molecule of oil (which is basically a line of carbon atoms with an “acid” group at the end, see oleic acid here(1), the acid is the part with the Os) has a double bond in the n position counting from the “tail.” The end of the drawing is a carbon, every angle is another carbon. If you count from the tail, you’ll see the = is at the 9th position. So yes, oleic acid is an omega-9 acid.
(1) the drawing in the English version is different. It may be more “dynamic looking,” but this one is the usual one, being more compact.
