Pharmaceutical Grade Fish Oil

A member asked why CVS has stopped selling its Pharmaceutical Grade Fish Oil. We asked CVS, which gave no good reason, but we suspect that the product may have been considered an "unapproved" medication due to its similarity to prescription fish oil.

Fish Oil Helps in Schizophrenia

A study found that concentrated fish oil greatly reduced symptoms in more people who had recently experienced a first episode of schizophrenia than did a placebo. The greatest effect was on depressive symptoms, which is consistent with other studies which have shown fish oil to reduce depression, particularly in people who do not regularly eat fish.

This impact on depression has also been suggested as one reason why fish oil has shown some benefit in people with cognitive decline. Details about the studies and products used, including our tests and reviews of similar fish oil supplements, are found in the Fish Oil and Omega-3 Fatty Acid Supplements Review >>

Higher levels of B vitamins and vitamins C, D, and E, as well as marine omega-3 fatty acids (EPA and DHA) appeared helpful. On the other hand, higher levels of trans-fats (from hydrogenated oils) had a negative impact. You can learn more about each of these nutrients in our various reports.

Studies are showing that higher blood levels of DPA (an omega-3 fatty acid obtained from fish) are associated with healthier aging and reduced cardiovascular disease. Although a cause-and-effect relationship has not been established, if you're interested in increasing DPA in your diet, we just published the amounts of DPA that we found in popular brands of canned tuna and salmon. Some had virtually no DPA, while others provided nearly 100 mg per serving. (Also see our Top Picks for Canned Tuna & Salmon.)

Supplement vs. Prescription Fish Oil?

As we have written before, by choosing an extremely concentrated fish oil supplement, you can get essentially the same type of fish oil as you would get from a prescription fish oil. But according to a recent study, fish oil supplements are more likely to be rancid (oxidized) than prescription fish oil. However, a closer look at the study by ConsumerLab staff suggests that this finding may be misleading, as explained in the "Quality Concerns" section of the Fish Oil Supplements Review >>

Olive Oil Review Expanded: Many Do Not Make the Grade

We tested three new olive oils based on reader requests, and the results are in! Our new tests included two olive oils that claim to be high in polyphenols, and the results were surprising:

-- One olive oil was rated so poorly by our professional taster it was considered to be "lampante" -- i.e., not fit for human consumption.

-- The other high-polyphenol oil delivered a good amount of polyphenols, rated well for taste, and is now our new Top Pick for a very high-polyphenol olive oil.

We also tested California Olive Ranch Global Blend but were somewhat disappointed.

Best Olive Oil for Heart?

This week, the FDA agreed that oils that are at least 70% oleic acid may claim to reduce the risk of coronary heart disease when substituted for saturated fats.

Spoiled Fish Oil Is Less Effective

Spoiled fish oil does not lower LDL "bad" cholesterol, while the same amount of non-spoiled fish oil does, according to a new study. If you take fish oil to improve your cholesterol levels, it would seem best to use a product that is not spoiled — something ConsumerLab tests for.
