Fish Oil Supplements
Fish oil supplements have been receiving a significant amount of attention lately for both their health benefits as well as claims regarding their purity and quality. Concerns have been raised that fish oils may be contaminated with heavy metals or other toxins. Fish oil used by Douglas Laboratories is taken from clean, unpolluted waters and prepared using a molecular distillation method that serves to eliminate heavy metals and other potential contamination. The fish used to create our fish oil products come mostly from the cold waters of the Atlantic and Pacific oceans. An additional complication that has recently entered the world of fish oil is use of the phrase "pharmaceutical grade fish oil." This phrasing can be seen on some internet sites and is being used to describe a specific classification of fish oil that is somehow "better" than other forms. While the term sounds official, "pharmaceutical grade fish oil" does not exist. For something to be truly considered "pharmaceutical grade" it must have a classification and appear in an official compendium, such as the USP. This would then define exactly what the substance is, what it should and should not contain, amount of active components, etc. No such compendial designation exists for fish oil. Don't get caught in the trap of the term "pharmaceutical grade fish oil." A quality fish oil product should be derived from fish taken from clean water, processed via a method using molecular distillation, and supply a significant amount of omega-3 fatty acids. Mercury, lead, arsenic, and cadmium should all be < 0.1 ppm. Figure 2 shows a recent independent analysis of our DEPA product. Note that heavy metals are all < 0.1 ppm.
