In the past, women have sometimes been cautioned not to take fish oil during pregnancy. Today, most healthcare practitioners recommend a good omega-3 supplement, as long as it is carefully selected. Here, you can learn about the selection criteria that anyone should use and the benefits of supplementation.
There are four main things that should be considered when choosing a supplement. Those are:
Purity
Freshness
Source
Omega-3/DHA content
Let’s look at each of those things in a little detail.
In order to judge the purity of a supplement before you buy it, there are a couple of different things that you can look for. Manufacturers that adhere to the International Fish Oil Standards are relatively pure, but some companies have even higher standards. The best way to judge purity is to look for the manufacturer’s COA or certificate of analysis.
The analysis is conducted by an independent laboratory and will list:
Common contaminants and whether or not they were detected
Oxidation levels, which indicates freshness
Omega-3/DHA content
So, three out of the four criteria relevant to taking fish oil during pregnancy can be determined simply by viewing a manufacturer’s COA. Now, why are those things important?
Mercury and PCB contamination is common in our oceans, the fish and their oils. Exposure to mercury or PCBs during pregnancy can cause birth defects. The COA should indicate that the contaminants were not detected in the oils.
High oxidation levels indicate that the fish were allowed to rot on the deck or dock, before the oils were extracted and encapsulated. Spoiled oils cause fishy tasting burps and nausea, things that no pregnant woman needs.
