Calanus oil supplements effective for Omega-3 Index increases

Scientists from Leibniz University Hannover and Justus-Liebig-University Giessen reported that two grams per day of Calanus oil increased the Omega-3 Index from 6.07% at the start of the study to 7.37% after 12 weeks.

“This is the first study to show that intake of 2 g [calanus oil] over a period of 12 weeks significantly improves the O3I in elderly participants engaging in a moderate exercise intervention while exercise alone did not affect the O3I,” ​they wrote in the British Journal of Nutrition​.

“These data provide the first indication that wax ester-bound n-3 PUFAs from [calanus oil] are well absorbed and are suited to cover the n3-PUFA supply.”

The Omega-3 Index measures the level of long-chain omega-3 fatty acids, EPA+DHA, in red blood cell membranes expressed as a percent of total fatty acids.

An Omega-3 Index in the range of 8-12% is one indicator of better overall health. As a part of an overall healthy lifestyle, an Omega-3 Index in the 8-12% range may help to maintain heart, brain, eye and joint health. 

Sourced from copepods

Calanus oil is extracted from the copepods of the same name, Calanus finmarchicus. ​According to Salma et al. (Prostaglandins Leukot Essent Fatty Acids​, 2016, Vol. 108, pp. 13-21), Calanus finmarchicus​ is “the most abundant crustacean in the North Atlantic Ocean with annual production of several hundred million tonnes.

“The total annual harvest amounts to less than 0.01% of the annual growth in accordance with regulations by Norwegian fisheries management.”
