For people with a truly balanced diet and healthy GI tract, oral multivatamins appear to have relatively small benefit, but they can clearly make a difference for people will subclinical nutrient deficiencies, which may be more common than official statistics.
Omega 3 fatty acid have proven health benefits. But it is best to get them from eating fish - just make sure you eat fish that has low risk of mercury accumulation. |
Also I see that alot of people are taking flax seed oil to get the omega-3's. I think this is a mistake simply because although linolenic acid, a fatty acid in flax has some intrinsic benefits, it's conversion to (umm is it epa or dha, i can't remember, I’m too lazy to google) I think epa, is dependant on the delta-6-desaturase which I have been told is easily inhibited by various factors and is present in varying amounts due to biochemical individuality. Why not just take performed fish oil with both epa and dha with no omega 6's which can convert to pro-inflammatory acids. ahhh this brings back *fond* memories of bio-chem... |

| I grind flax seed in my coffee grinder . I take 1 TBSP/ day . Is the flax seed better for the Omega 3 than flax oil ? |

I'm not sure what you mean. Most forms have around 100 to 200 mg each of epa and dha per 1 gram of fish oil. I have bought the "deoderized" forms but I found that freezing the fish oil caps does just as well. |

with fish oil it is buyer's beware of fish oil contamination ! " As good as it is ,it has a drawback: contamination . the vast majority of fish oil supplement in health food stores are only one step removed from the outflow of any major chemical processing plant .
Farmed fish have to be fed crude fish oil in order to attain normal growth . Of course the crude fish oil is contaminated with toxins. this is why the levels of PCB and dioxins in farmed fish are actually significantly greater than in wild fish. So you get a dose of toxic substances if you take fish oil supplement in high amount. " It all depends on the manufacturing techniques !
what brand do you use ? |

Chris , this is the info : the lab is at the University of Guelph in Canada. They test & post the level of toxins in fish oil sample. They post the batch # & the result . Also it is free ! International Fish Oil standard. If I remember brands like The Zone , Dr Weil , Nordic Natural ..... ultra refined concentrate.... You will find the info at www.ifosprogram.com .
Hope this will help you . |

thank you for posting this info. this lab give great info . I was even able to look the batch # of the fish oil ! It gives the batch result for mercury PCB Dioxins , oxidation & peroxide.
It gives the concentration of omega 3 EPA/ DHA . From now on I will purchase Dr Weil omega 3 complex ultra-refined capsules. The Zone fish oil is too expansive. |

Dr Todorov ,
I look at the website posted www.ifosprogram.com for the fish oil. They post total oxidation / peroxide result . Can you explain what peroxide means in fish oil capsules? |

Peroxide is any molecule of type R-O-O-R , where O is oxygen and R could be hydrogen or fatty acid or other molecule. If both R are hydrogens, you get hydrogen peroxyde. If case of oil and/or lipids, you get R-O-O-H or R-O-O-R where R is a fatty acid.
Oil/lipid peroxides are created in the process of oxidation of oil, including fish oil.
All peroxides are harmful as they create free radicals. |

They don't provide that much detail on what analytical chemistry methods they use for testing, but if their data are accurate, it can be useful in selecting the best brand.
They use maximum allowable amounts of contaminants from guidelines of Council For Responsible Nutrition. I do not know what this council is and how they derive their guidelines.

It's interesting. Maybe I am mistaken but I think that the companies are submitting their products for testing which means that they are probably giving them their best lot of product but these companies are known to be reputable so I’m sure all of their lots are of good quality. If I can get some more info I may be able to do some analytical tests here at the University on my Rexall brand of fish oil. |

| It is somewhat of a red flag if indeed the companies submit samples themselves. But if it is a large entablished brand, the lot variation is likely to be relatively small due to standardization of technological process. |
