Just a couple years ago flax oil was touted as essential for anyone who wanted to improve health or body composition. However, the recent popularity of fish oil has undoubtedly left some people confused. While there are several reasons I’d opt for fish oils, I’ll present one argument here. 

Flax oil provides both Omega 6 and Omega 3 fats. Since most North American diets provide Omega 6 in excess of our requirements we are typically out of balance. We have far too much Omega 6 and far too little Omega 3.

 

Illnesses associated with having too much Omega 6 include: 

ADHD, allergies, eczema, asthma, breast cancer, colon cancer, prostate cancer, lowered immunity, heart disease, strokes, diabetes, high blood pressure, depression, fibromyalgia, ulcerative colitis, Crohn’s disease, arthritis, osteoporosis, and Alzheimer’s, painful menstruation, back pain, neck pain, and headaches.

Flax oil also provides its Omega 3’s in the form of Alpha-Linolenic Acid (ALA). Since the body prefers to use Omega 3’s in the form of EPA and DHA some conversion is required.

Unforunately, one of the major enzymes required for conversion (delta 6 desaturase) is impeded by high Omega 6 intake, saturated fat, vitamin or mineral deficiencies, alchohol, and stress. The average North American would be lucky to get a 10% conversion.

Fish Oil provides Omega 3 fats and very little in the way of Omega 6. It also provides almost all of its Omega 3’s in the form of EPA and DHA. It essentially skips the conversion process and gives the body what it needs immediately.

One Final Comparison

1 tsp flax oil contains 57% (or 2850mg) ALA.
After conversion this yeilds:

EPA: 5.7mg
DHA: 1.34mg

1 tsp fish oil with no need for conversion:

EPA: 800mg
DHA: 500mg

While I could probably go on for hours about this, the simple fact is that you’re going to get more of what you need when you need it with fish oils.
