<p>Walnuts are also high in omega3. Whether you burp from these is up to you!</p>
<p>Nut allergy.</p>
<p>DS takes them all the time. He has me buy the ones with enteric coating. Says that takes away the issue of burping/fish smells.</p>
<p>I take 1200 mg of omega-3 fish oil supplements and have not seen any adverse side effects. I also take Vit’s E, B-12, C and a multivitamin. I never get colds or the flu and feel great for a 60+ non-AARPian. I also try to eat at least 3 servings a fish/wk.</p>
<p>I have read about Puritan Pride’s excellent quality of supplements and know that my sis uses them, along with a cider vinegar capsule, which helps control her high blood sugar. Apparently, she is very happy with this mail order company.</p>
<p>Pure canola oil or olive oil are also high in Omega-3’s… other cooking oils, not so much.</p>
<p>I have taken 4000mg a day of fish oil capsules for five years. I take them last thing at night, so if I’m burping, I don’t know it <lol>.</lol></p>
<p>Puritans Pride line of supplements was recommended as the top brand by the UW sports nutritionist who gave a talk at D’s team nutrition seminar. Apparently, they use natural isomeric forms of chiral vitamins, not the racemic mix usually found in store brands.</p>
<p>“natural isomeric forms of chiral vitamins, not the racemic mix usually found in store brands.”</p>
<p>This is why I hate to get into taking supplements of any kind. There is so much I don’t understand or care to understand.</p>
<p>I asked about fish oil in January. You might find some help here too.</p>

<p>I had major problems with fishy burps and switched to this brand:</p>
<p>[Double</a> Strength Odorless Fish Oil | Nature’s Bounty | Walgreens](<a href=“http://www.walgreens.com/store/product.jsp?CATID=100178&navAction=jump&navCount=0&skuid=sku3429602&id=prod3430762]Double”>http://www.walgreens.com/store/product.jsp?CATID=100178&navAction=jump&navCount=0&skuid=sku3429602&id=prod3430762)</p>
<p>No more fishy burps. :)</p>
<p>Fish oil does have a side effect of “fish” burp.<br>
It is generally accepted that fish oil does help to lower triglyceride levels. However, the dose for this effect is a minimum of 3.8 grams per day. You won’t see a significant effect below that amount. You have to be very careful about choosing a supplement because most of them are of bad quality. Good manufacturing standards are just beginning to be phased in. They will be completely enforced by July 2010. There are supplements/vitamins which don’t dissolve. Some are not true to their label. I recommend you buy supplements which are USP certified. It shows they are of minimum quality.
The issue with the supplement studies, in general, you cannot generalize them . For each result, you can say it is only true for that brand because there is no standard.
Most things in nature come in racemic mixtures. Whether or not it is one isomer or another only matters with amino acids. A lot of the times, molecules actually flip between isomers.</p>
<p>Nova, in addition to amino acids, nucleic acids and their building blocks, nucleosides and nucleotides, are chiral, too, as well as many sugars. Whether the so called D or L isomer is the natural form - it depends on the molecule. Nature loves chirality, since it helps differentiate the “good” from the “bad”. L isomers (non-natural ones) of nucleosides, for instance, are being pursued as antiviral drugs. Viral repliucation machinery is primitive enough not to “see” the differnces between D and L isomers, at the same time the human enzymes have much higher recognition standards. The result should be a drug that “hits” only the viruses, and does not have any side effects in human cells (in theory; in practice one has to worry abou too many other things).</p>
<p>Back to vitamins. Tocopherol (Vit. E) is one of such chiral molecules. Synthetic tocopherols (the cheap stuff) have a 50-50 mixture of chiral centers (DL, RS or +/-).</p>
<p>Is there an “eyes glazing over” emoticon I can add here?
I may just skip the fish oil. Sounds like it’s very hard to gt the right kind that does the right thing without side effects.</p>
<p>Six grams a day here. I use the ones from VitaminShoppe, aiming for a dosage of 1800 DHA/1200 EPA a day. </p>
<p>Pure canola oil or olive oil are also high in Omega-3’s… other cooking oils, not so much. </p>
<p>Canola oil has NO Omega 3s. It is pure 6. Olive oil is omega 9 (which seems to have no positive benefits other than the fact that it isn’t a 6 - which is big.)</p>
<p>“It is generally accepted that fish oil does help to lower triglyceride levels. However, the dose for this effect is a minimum of 3.8 grams per day.”</p>
<p>This is for the FDA-approved fish oil Lovaza (which will cost you $80/month.) You can get the same dosage by callibrating the DHA/EPA ration using other brands. (That’s how I know the 6 gram of VitaminShoppe or 10 grams of Costco brand do the trick.)</p>
<p>However, dosage is a tricky question for fish oil generally speaking. The health benefit doesn’t come from the fish oil per se, but rather from changing the ratio of Omega 3s to Omega 6s. So eliminating 6s will have equivalent impact.</p>
<p>Full replacement in the body, brain, nerves, etc., is said to take around two years, though benefits are often seen in 3-4 weeks.</p>
<p>missypie, sorry for the confusing gibberish about chirality. You do not have to worry about that stuff with fish oil. We went off the main track there with our discussion of other vitamins. And you probably do not have to take as much as mini’s mega-doses for cardiovascular problems. D was told to take 2 capsules of Costco or similar brand fish oil (or flaxseed oil) daily for her dry eyes.</p>
<p>Some of us finished chemistry in 1976 and never looked back.</p>
<br>
<br>
<p>Not in biological systems. It’s almost always true that one enantiomer or the other is biologically active and not both. With a few very rare execptions, amino acids from biological sources are always L. Sugars are always D. And so on. Racemic mixtures occur only in synthetic or inorganic sources. </p>
<br>
<br>
<p>Wrong again. Due to the high specificity of enzymes, only one enantiomer in a racemic mixture will be biologically useful. The other will be inert. This applies equally to amino acids, sugars, or lipids. For example synthetic vitamin E will be a racemic mixture: DL-tocopherol. But only the D form can be absorbed and used by your body. If the vitamin E is derived from natural sources it will consist of only the D form to begin with.</p>
<p>As for fish oil, if it is really derived from fish and not adulterated with other oils, it will automatically consist of only the correct biologically active isomers.</p>
<p>(coureur, psst, we are not supposed to be discussing this stuff here. We have to help missypie develop affection for fish oil supplements, and this isomer discussion does not sound too appetizing to some ;))</p>
<p>I’ve had bad side effects to Costco/Kirkland and other brands of fish oils but have found MegaRed omega-3 krill oil by Schiff from Costco to be easy to take and well tolerated. Schiff claims that krill oil is more easily absorbed and “stronger” than fish oil (on a mg for mg basis) because it’s in a phospholipid form instead of a triglyceride form. They say that 1 MegaRed = 3 typical fish oil capsules. Schiff also claims environmental sustainability and product purity for the stuff.</p>
<p>I’ve never taken chemistry but talk to me about molecular distillation, yes or no?</p>
