- Can the body convert ALA from Udo’s Oil Blend into the n-3 derivatives EPA + DHA contained in fish oils? If so, how much conversion takes place?
- Is conversion sufficient for health needs?
The second study, done with six men, showed that the men converted an average of 16% of the ALA they received into long-chain n-3 derivatives (8%EPA, 8%DPA). In this study, the men produced no DHA. However, another study showed that men convert ALA to DHA as well.
Using rate of conversion measured in the study with men, how much ALA is converted? A 150-pound man converting 16% of the recommended 3 tablespoons/day (again, 1 tablespoon/50 pounds of body weight/day of Udo’s Choice Oil Blend) ends up with 3,360mg of long chain n-3 (EPA + DPA), the equivalent of 11 large capsules of fish oil. This again is more than the highest recommended therapeutic dose of fish oil. The fact that no DHA was produced in the study with men prompted the researchers to speculate that men may need to eat fish or take fish oil supplements, but other studies find that men do make DHA.

Isn't it better to cite a study that isn't offered by the company that sells udo's?
It even states that DHA isn't produced requiring supplementation of fish oil. A blend of both would probably be better.

Hence the first line of the beginning of my post.Originally Posted by evoVIII
The answer to biggun's question is clear even by Udo's own admission: For males, ALA will convert at a substantially lower rate than fish oil.
I'll hazard a guess that Udo didn't commission the research study done by the BJN, rather that he is only referencing it. Probably more troublesome is that the study uses a sample size of six, calling into question its satistical significance given the size of the population. Still, when it comes to fats Udo has a wealth of knowledge that should not be discounted off-hand. Udo's Choice Blend mixes a variety of oils (flax, sunflower, sesame, rice germ, oat germ, evening primrose, MCT, coconut). His goal was to create a blended balance of what he considers the optimal ratio of n-6 to n-3.
However, I certainly agree with you that it would be better to have an unbiased study comparing the two. Feel free to post a reference to such a study.
