Fish Oil


Omega-7 fatty acids are unsaturated fatty acids found in certain fish, like salmon and anchovy, and oils such as olive oil, macadamia oil, and sea buckthorn oil. Palmitoleic acid is one of the most common omega-7s. One small, but placebo-controlled, study using a palmitoleic acid-rich supplement (made from specially-processed anchovy oil) found that it significantly lowered levels of CRP (a measure of inflammation in the body), triglycerides, and LDL ("bad") cholesterol, while increasing HDL ("good") cholesterol.  

Interestingly, if you take a fish or krill oil supplement, you may already be getting significant amounts of omega-7s but this depends on the type of oil, with some containing no omega-7s. These amounts are typically not listed, but we checked omega-7 levels in the supplements we tested.

You can find these amounts, as well as more information about omega-7 fatty acids, and what are claimed to be "omega-10s," in our Fish and Marine Oil Supplements Review >>

I have really bad gums; taking sea buckthorn (Life Oil from has been responsible for making my gums stronger and more healthy. I no longer have loose teeth.

Hi Max - The fact that sea buckthorn appears to have made your gums stronger may due to the fact that it is high in vitamin C - which is important for healthy gums and connective tissues. It's possible that you were deficient in vitamin C. In any event, glad it helped you. You may want to consider increasing your consumption of citrus and other sources of vitamin C (see our Vitamin C Supplements Review for more information:

I have used the Cardia7 from Tersus for many of my patients to lower CRP. It is effective, assuming no active infection or other cause. No side effects noted, probably about 30-40 people.

Thanks for this information.
This comment was written in 2014, so by now you probably have experience from much greater number of patients than 30?
