Five years ago, I went to see a naturopath about my PCOS. The first thing she said to me was, “We need to get you on a good fish oil.” I had never taken fish oil before and the idea of it actually made my stomach turn. I remember my Mom talking about how she had to take cod liver oil when she was a kid and how much she hated it. I expected the worse but was pleasantly surprised.

I have been taking a teaspoon of Carlson Lemon Flavored Fish Oil almost every day since and I can honestly say it actually tastes good. In fact, my whole family takes it.  My boys, ages 9 and 6 actually remind me to give it to them in the morning.

It is important that you purchase your fish oil from reputable companies who have verified by independent laboratory analysis that their product is free from chemical contamination. I like Carlson Very Finest Fish Oil Lemon Flavor because it is reasonably priced, around $20 for a 200ml bottle. The product is regularly tested (using AOAC international protocols) for freshness, potency and purity by an independent, FDA-registered laboratory and has been determined to be fresh, fully potent and free of detectable levels of mercury, cadmium, lead, PCB’s and 28 other contaminants.

Fish oil is harvested from cold water fish like salmon, mackerel, sardines, trout, herring, tuna, eel and anchovies. These fish are high in omega-3 essential fatty acids (EFAs), which break down into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EFAs are a primary component of cell membranes and hormones.  Together EPA and DHA  aid PCOS and fertility because they can help with hormone regulation and they are anti-inflammatory.’

Here is a little more detail about how Fish Oil can help with PCOS from

“There is a very important distinction between the omega-3 fatty acids in fish oil and omega-3 fatty acids found in most foods, such as nuts and seeds. Flax seeds or flax seed oil is a good example. The omega-3 fatty acids in flax are not the same as in fish oil. The oil in flax is called alpha linolenic acid (ALA). It must go through a metabolic transformation before it is converted into final omega-3 fatty acids called EPA and DHA. This transformation is controlled by an enzyme called delta-6-desaturase (D6D).

There are many factors that inhibit the performance of the D6D enzyme and thus reduce the conversion of alpha linolenic acid (ALA) into EPA/DHA. Among the D6D inhibitors are elevated cholesterol, caffeine or alcohol consumption, saturated fat or trans-fat consumption, vitamin and mineral deficiencies, and hormonal abnormalities, including stress hormones, insulin resistance, and hypothyroidism. Women with PCOS and infertility typically have some of the factors at play, possibly resulting in impaired D6D activity. The consequence is that needed EPA and DHA is not created in sufficient quantities.

Fish oil solves this problem. Fish oil already contains EPA/DHA. So when you consume fish oil, you don’t have to worry about how well your D6D enzyme is working. You have completely bypassed that metabolic bottleneck by ingesting your EPA/DHA instead of having to create it yourself.”

I personally have noticed that when I take fish oil my skin is clearer, my cycles more regular, my hair loss slows and my insulin sensitivity is improved.  However, make sure that you buy fish oil only from reputable companies who have verified by independent laboratory analysis that their product is free from chemical contamination and peroxides.
