Pharmaceutical grade fish oil is an interesting term, because the reality is that there actually is no such thing as pharmaceutical grade fish oil, other than the fact that it's a term - A  term used to signify a degree of quality - the highest quality at that -  of fish oil supplements available. Unfortunately, the U.S. Pharmacopeia does not actually publish any manufacturing and purity regulations for fish oil supplements. As a result, many an independent testing facility has surfaced to meet the needs of fish oil supplement manufacturers seeking scientific backing, or an accreditation of sorts that would help differentiate them from the rest of their competition. Out of these testing facilities, which in essence, are private organizations, the most respected standard that currently serves as a universal standard for fish oil supplement quality, it would, fittingly enough, be the International Fish Oil Standards (IFOS). Some manufacturers believe that if their fish oil supplements meet IFOS standards, which, in truth, are indeed tougher than "standards" used by many other manufacturers, their fish oil product should be endowed with the title of pharmaceutical grade fish oil. The only problem is that some of the standards have been deemed to be lacking in certain regards. In other words, if you are looking the for the highest quality fish oil supplement, which in actuality, is the same thing as "pharmaceutical grade fish oil", ensure that all  IFOS standards are being exceeded. The truth of the matter is there are few fish oil supplements that truthfully deserve to be called pharmaceutical grade. This said,  immediately below are the highest quality fish oil supplement brands currently manufactured and sold - no doubt about it.
