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.

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 >>

Algal Oil vs. Fish Oil

Fish get their omega-3's from algae and many people are now doing the same by taking algal oil, but how does it compare to fish oil?

Problem with Too Much Krill Oil

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.

8/22/2014

Flaxseed Lowers Blood Pressure

Concern with Rancid Fish Oil

As our tests have shown, some fish oils are spoiled by the time you buy them. Spoilage produces a variety of compounds. You can smell and taste some of these (if you take the oil directly by spoon, for example) but others you cannot. An expert panel recently reported on the safety of consuming rancid fish oil. See their conclusions in the Fish/Marine Oil Supplements Review, which includes our test results.

10/04/2011

Fish Oil's Impact on Cognitive Decline

Cognitive decline may be a normal part of aging, but a new study suggests that high-dose fish oil particularly rich in DHA may provide some benefit. In people over age 65 with mild cognitive impairment, fish oil was associated with improved verbal skill. Perhaps as important, fish oil also reduced depressive symptoms, which can be a risk factor in the progression to dementia.
