Watch your fish oil labels 17. December 2009 William Davis (36) A quick quiz: How much omega-3 fatty acids, EPA + DHA, are in each capsule of fish oil with the composition shown on the label below:If you said 1340 mg (894 mg + 446 mg), sorry, but you're wrong. There are 670 mg EPA + DHA per capsule. Did you notice that the composition, or "Supplement Facts," lists the contents of two capsules? Rather than the usual one capsule contents, this product label lists two capsules. I don't know why some manufacturers or distributors do this. However, I have seen many people tripped up by this kind of labeling, taking half the omega-3 fatty acids they thought they were taking. This can be important when you are trying to obtain a specific dose of EPA + DHA to reduce triglycerides, reduce Lp(a), control abnormal heart rhythms, reduce bipolar mood swings, or other important effects. I liken this to pulling up to a gas station where the sign says gasoline for $1.25. Wow! Can't beat that! You then find out that it's really $1.25 for a half-gallon, or $2.50 a gallon. In truth, the labeling is accurate; it's just very easy to not notice the two capsule composition.
