Some suppliers of fish oil claim that it does not matter that
EPA is higher than
DPA because
body will convert part of
EPA to DPA. This is indeed true but like
conversion of ALA to DHA
percentage of conversion is very low. This is due in part to
high consumption of Omega 6 in
typical Western diet. Enzymes needed for
conversion are in 'short supply' in
bodies of those people who have a reasonably high level of Omega 6 intake (via vegetable oils). This is because
enzymes needed are 'used up' in having to deal with
processing of Omega 6 oils. As a result,
conversion in most people is quite negligible which further supports ingesting
DHA directly. Important Point # 5
As I indicated earlier most fish oils are in
triglyceride forms. A triglyceride consists of 3 fatty acids attached to a glycerol backbone. It does not pass easily through
cell membrane as it is changed. It also requires two enzyme steps to 'release' its fatty acids.
Sometimes because of
structure of
triglycerides
fatty acids are not released but rather stay attached to
glycerol backbone. In contrast, if
oil is esterified during
concentration and purification processes
resulting substance can easily enter
body's cell membranes. The esterified molecule has no charge and only requires one enterase enzyme to release
fatty acid. (DHA). This enables
body to use it as an immediate energy source, or store it for later use. In Summary:
To receive
many benefits of DHA you have to consider ensuring that you do as follows: 1. Find a source of fish oil that is high in DHA or alternatively be prepared to take much higher doses of conventional fish oil. 2. Ensure that
fish oil you use is molecularly distilled. 3. Try to find
oil in
Ester form for better bio-availability. In conclusion, try to find a quality fish oil supplement that meets these three criteria and your benefits will far outweigh
cost.
