This is the first time I've looked for Lovaza here, though I know this is not the normal way for Wikipedia to list medication or suppliments, it is what's here. I'll take a picture and work on adding some basic information here. It might be better as Omega-3-acid ethyl esters (LOVAZA) as it's noted in the GlaxoSmithKline information on it and is more normal for Wikipedia. --Bcw142 (talk) 23:13, 18 March 2009 (UTC)[reply]

Note: 38% + 47% + 17% = 102% (>100% due to rounding)

Question: Is rest all fish oil?

"Each 1-gram capsule of LOVAZA contains at least 900 mg of the ethyl esters of omega-3 fatty acids sourced from fish oils. These are predominantly a combination of ethyl esters of eicosapentaenoic acid (EPA - approximately 465 mg) and docosahexaenoic acid (DHA - approximately 375 mg)." Source: http://us.gsk.com/products/assets/us_lovaza.pdf (Section 11 Description)

Hence: ~37.5% DHA ethyl esters, ~46.5% EPA ethyl esters, >=~6% other Omega-3 (which equals >=90%) Hence: ~10% other fish oils (an assumption?)

Can someone explain the signicance of ethyl esters versus "natural forms"? —Preceding unsigned comment added by 96.241.3.227 (talk) 07:18, 22 July 2010 (UTC)[reply]

Possible contextual discussion needed: The third sentence of this article (as of 22 OCT 2010) describes the process by which GlaxoSmithKline "transformed" a dietary supplement into a "pharmaceutical." Was there any controversy about this? That is to say, it seems to me that what GlaxoSmithKline appears to have achieved is to convince the FDA to approve an excluse right to market (purified) fish oil as a pharmaceutical (with all attendant potential financial gain) while others must market it as a dietary supplement. Does this fit within standard practice of the FDA? Could another company, for example, apply to the FDA to market St. John's Wort capsules as a "pharmaceutical" with exclusive rights?

"Natural" fish oil contains fatty acids incorporated into triglycerides and as free fatty acids. Making an ethyl ester involves converting everything to free fatty acids, getting rid of saturated fatty acids, which has the effect of concentrating EPA and DHA, and then sticking an ethanol molecule on one end. Hence ethyl for the ethanol and ester for the fatty acid. Any product with ethyl esters should not be described as 'natural.' David notMD (talk) 10:28, 8 April 2017 (UTC)[reply]

Because many popular fish oil supplements use ethyl esterification to avoid contaminates as well[1], I changed:
in these respects it is considered a pharmaceutical: unlike unregulated extracts, there is no risk of contamination by methyl mercury, arsenic, or other pollutants that are often seen in the world's oceans.
to:
Due to the esterification process during manufacturing there is no risk of contamination by methyl mercury, arsenic, or other pollutants that are often seen in the world's oceans.

Confirming that in that link, Vitamin World Ester-Omega is an ethyl ester dietary supplement ingredient. Almost all of the other products in that link are not ethyl esters. David notMD (talk) 10:33, 8 April 2017 (UTC)[reply]

See discussions at Talk:Omega-3 fatty acid about making all these fish oil/omega-3 articles make sense across Wikipedia. Jytdog (talk) 00:52, 1 April 2016 (UTC)[reply]
